Description:
ECOLOGICAL SYSTEM EXPLOITING KINETIC ENERGY IN VEHICLES

FIELD OF THE INVENTION

The present invention relates to the field of alternative energy generation applied to land and nautical vehicles. In particular, it relates to an ecological system which uses kinetic air Flow of a moving vehicle for reducing its weight through simultaneously or alternatively the aerodynamic lift of a vehicle and/or producing electric energy.

BACKGROUND OF THE INVENTION

Every land or nautical vehicle moving on the ground or sea Surface and displacing by its movement an airmass constituting our atmosphere is a potential energy source which today is underutilized. The use of this source may lead to a Benefit for our planet, offering solutions related to reducing fuel and transport supplies consumption, usually derived from non-renewable resources, reduction of residues linked to the use of such supplies, and thus lowering transport costs, increasing efficiency. The Benefit obtained out of these solutions will surely be tangible to present and future generations, which duty is to attempt a lower consumption of non-renewable resources, without affecting productivity. On the other hand, there is the need for finding alternative energy sources which are friendly with environment and minimizing the use and impact of energy generation from non-renewable natural resources, which in turn are less costly and easier to obtain.

In effect, every vehicle in movement, be it a truck, a car, a boat, a train, etc., displaces and compresses an airmass which appropriately leaded and compressed can be used as a new energy source which today is being wasted.

Therefore, the inventors of the present invention made possible to use and address a great portion of wind energy generated by those moving vehicles which penetrate the surrounding airmass and thus producing the reduction of payload through aerodynamic lift on the vehicle and, simultaneously or alternatively, incorporate a subsystem capable of electric energy generation.

Document US 201 1/0181072 discloses an aerodynamic wing mounted on the upper part of a vehicle such as a car, a load wagon of a truck, or the load wagon of a tractor. This apparatus allows an improvement of the aerodynamic movement of the vehicle through the air.

US patent No. 8205932 describes a lift wing structure for a semitrailer of a tractor-trailer rig, for producing various aerodynamic effects, such as turbulence reduction, lift creation and downward force creation. The lift wing apparatus is mounted in a trailer chassis and extends upward to a height that is approximately the portion of the tractor cabin. The lift wing apparatus comprises a stationary pedestal structure having a pair of joined vertical hydraulic cylinders connected to the wing portion. Said hydraulic cylinders allow the operator to make height adjustments of the wing when during transit through a remote control within the cabin area.

Documents US 201 1/0181072 and US 8205932 describe systems or wing structures for producing aerodynamic effects in vehicles. But, such systems do not show devices or apparatuses that generate a real compression, which efficiently allows reduction of weight through aerodynamic lift in the vehicle, without significantly affecting vehicle size. Furthermore, such systems do not offer solutions that commercially sustain a favorable equation for significantly reducing fuel or supply consumption or which improves vehicle efficiency.

US Patent No. 5280827 describes a standard vehicle driven by an electric motor, an improved battery charging system comprising an wind turbine mounted in the back of the vehicle, a Venturi tube extending along the upper part of the vehicle and a pair of lower Venturi effect tubes extending along lower sides of the bodywork of the vehicle, which guide the air flow to improve the force directed to the turbine. It also describes floor effect systems for stabilizing the vehicle, along with solar cells.

Publication No. WO201101 1856 provides an energy recovery system for a vehicle comprising an electric generator provided with a housing, said housing is oriented with respect to the vehicle around a housing axis. Said system also comprises a wind turbine containing a set of Blades oriented with respect to a Blade axis. The wind turbine is supported on a housing and can rotate around its axle. Said electric generator is coupled to the wind turbine and converts rotation movement energy of the set of Blades into electric energy. US patent No. 7808121 provides a land vehicle having electric energy generation including an energy storage battery, additional electric energy generation includes a housing, a set of rotating Blades or paddles in the housing, a moving axle connected to said set of rotating Blades, an electric connection to the storage battery to provide electric power. The housing has at least one frontal air inlet aperture and an air outlet open area downstream of the blades and the frontal aperture has at least one gate. The gate only opens when the vehicle is deaccelerating or stops and closes when the vehicle is moving.

Documents US5280827, WO201 101 1856 and US7808121 disclose vehicles having electric energy generation apparatuses which use wind turbines and solar panels, but the proposed solutions provided by said apparatuses and/or vehicles substantially affect their sizes and utility, affecting commercial feasibility of their use or incorporation within the current market. Besides, they do not have a real compression system which allows feedback of the vehicle without significantly affecting the vehicle dimensions.

Therefore, there is the need of a commercially feasible ecological system which complies with current regulations of land transport vehicle dimensions, which efficiently use the air flow in a moving vehicle that provides a real compression of the airmass for reducing the weight of the vehicle without significantly affecting vehicle dimensions and/or generating a significant amount of useful electric energy.

BRIEF SUMMARY OF THE INVENTION

The inventors of the present invention recognize the importance of environment care and obtaining important money and resource economies in the transport industry, and thus provide a system that uses air flow of moving vehicles wherein said system directs said flow towards one or more subsystems to reduce the weight through aerodynamic lift provided to the vehicle and/or electric energy generation.

Having the ecological system of the present invention the weight of the moving vehicle decreases and thus fuel costs, tire costs and general maintenance costs are also decreased and therefore particles that contaminate environment are also diminished. Furthermore, bearing impact of the vehicles on road networks is reduced, thus contributing to maintenance cost reduction. The ecological system of the present invention is preferably addressed to vehicles that can regularly reach speeds between around 80 to around 120 km/h, even though the aerodynamic effect is present with speeds exceeding around 40 km/h.

One of the objectives of the present invention is lightening the payload of the vehicle through aerodynamic lift generated by the system.

For increasing the lift of a moving vehicle is provided as a part of the ecological system a device directing the today’s wasted airmass, compresses it and accelerates it such that the output speed of the air reaches around four (4) times the input speed. Consequently, the impact speed of the airmass against the aerodynamic profile which is also a part of the ecological system of the invention, generates a truly useful lift effect on each type of vehicle in the market.

Another objective of the present invention is to generate electric energy and decrease contaminant emissions released to the atmosphere.

An additional purpose of the invention is to use and optimize vehicle’s aerodynamics using its original morphology, thus obtaining proposed aerodynamic or energetic results.

Another objective of the invention is to provide an ecological system that is adaptable to the original morphology of a vehicle or that is an integral part of the vehicle. A further purpose of the invention is to provide means for reducing environmental impact produced by noise made by some of the system components.

Additional objectives and advantages of the present invention will become apparent in the description of the figures, the detailed description of the invention and the proposed claims. LIST OF ELEMENTS OF THE SYSTEM OF THE INVENTION

Among flexible elements there are, among others, bellows, composite or textile materials, or diaphragm type of elements. The first subsystem (12-000) of the ecological system of the present invention is a body of aerodynamic profiles (12-100) optionally comprising one or more wing tip devices (12- 121) shown in figure 40. The one or more aerodynamic profiles (12-100) comprises one or more vortex generator devices (12-130) also shown in figure 40. The one or more aerodynamic profiles (12-100) comprise one or more flow guides (12-140) although not shown in the figures. Said aerodynamic profile (12-100) comprises a lightened structure (12-110) shown in figures 40 and 41 located within said aerodynamic profile (12-100).

Figure 40 shows the profile in construction, or lightened structure (12-110), in which ribs to be perforated are shown, the skin (12-114), and the coupling elements (12-115).

The ribs (12-111) are rigid structures adapted to the aerodynamic form which reduce the profile’s weight without affecting its sturdiness, and the skin is adhered to the ribs (12- 111) and altogether form the first subsystem (12-000).

Said housing (13-100) has displacement means, preferably one or more rails, on its side walls so that said subsystem can be retracted and thus facilitate its uninstalling and transporting.

Turbines (13-200) can be longitudinal or axial type as shown in figure 1 1. In a preferred embodiment turbines (13-200) are wind turbines which compress striking air, and address it towards the air exhaust elements (13-900) and to the noise cancelling elements (13-700), turbines (13-200) rotate in opposite directions, additionally, as the air strikes with their Blades a coil in the center of the turbine (13-200) rotates and induces electron flow in an axle supported in the housing wherein energy is distributed to converters or to energy storage batteries (13-310), shown in figure 17, which can optionally be part of the system or lodged in the vehicle.

In other embodiment of the invention, the first subsystem (12-000) and the second subsystem (13-000) of the ecological system (100) operate together. For example, figures 50 and 51 show a preferred embodiment of the ecological system (100) that uses kinetic energy for a moving vehicle (400), wherein the vehicle (400) is an articulated truck having subsystems (12-000) and (13-000) jointly operating.

Likewise, it shows the grille (11-100) found at the input of the device (11-000) and is useful as backup in case that the system of the invention receives an amount of air greater than that one supported by the system. In such case, the grille (11-100) closes to avoid unwanted effects, such as instability, overturn or energy overcharge in the energy generator. Also, figure 4 shows the device (1 1-000) with the second subsystem (13-000) with the energy generator with its turbines (13-200), its air collecting and reduction system and its exhaust tube, its output system.

In another embodiment of the invention the ecological system of the invention, it can be an integral part of a vehicle. For example, in Figures 54, 55 and 56 it is observed that the ecological system of the invention is an integral part of a truck by means of a head (14-000) containing the one or more devices (11-000) and (14-100) and grilles (11-100).

Next, we disclose some examples of the ecological system of the present invention, which in any way intend to be limitative but they intend to show the technical improvements and advantages of the invention.

In these examples, the system of the present invention is addressed to moving vehicles (400) running at speeds from around 80 to around 120 km/h, in which desired lifts are reached such as shown in table 1.

The ecological system of the present invention weighs around 550 kg, which can vary depending on the construction material and different embodiments and modifications that can be made and that are found within the scope of the invention.

Said subsystem (12-000) or aerodynamic profile has a weight between around 200 and around 250 kg, which can also vary depending its construction material and modifications made and found within the scope of the invention. The system measured around 40 cm height, which complies with one of the objectives of the present invention which is providing a commercially feasible system and that complies with the international standards for load vehicles.

EXAMPLES

Example No. 1 (Lightening of the weight of the vehicle through lifting) Under international standard for load vehicles such as box trucks, articulated trucks, the maximum height of the vehicle is around 4 m, the maximum width is around 2.60 m and the minimum height of the gauge of the bridges is around 5 m, according to“AASHTO LRFD Bridge design Specifications” 6th ed. (2012) and“AASHTO LRFD” Bridge design Specifications 7th Ed. (2014).

With a view to offer, a commercially feasible system and complying with existing vial infrastructure standards and the above mentioned, in this example aerodynamic profile type E 61 Ci (Eppler 61) was selected, which shows an effective behavior for the functioning of the system without substantially altering vehicle dimensions, namely, height and concomitantly comply with the above-mentioned standards.

Figure 52 shows various behaviors of aerodynamic profile type E 61 Ci (Eppler 61) in terms of lifting coefficient (Ci) and attack angles (Alpha), when subjected to conditions corresponding to different Reynolds (Re) and varying air density. In figure 52, T1 corresponds to the same time or period for different Reynolds numbers.

The aerodynamic profile type E 61 Ci (Eppler 61) shows a lifting coefficient enough for generating a lift applicable to lighten the payload at achievable speeds for heavy load transportation. It is a profile that generates an ideal lifting with zero attack angle and therefore, this profile allowed significantly reduction the impact of using the system at the height of the vehicle.

A comparison between a system of the state of the art without device (11-000) and an embodiment of the ecological system of the present invention comprising device (11-000) and the first subsystem (12-000) which receives the air flow projected from the device (11-000) towards an aerodynamic profile (12-100) which generates lightening the payload through lifting the moving vehicle was carried out for example 1. Design parameters at sea level and at 4,000 mosl were used. The desired lifting was obtained by decreasing the input area of device (11 -000) from 4 to 1 so that the relation of output air velocity is four (4) times the impact air velocity against the subsystem (12-000) or aerodynamic profile. The following Table 1 and Figure 53 show different results in terms of kilogram force of lift reached from independent use of profile (A), that is, without incorporating the characteristics of the present system, against results in terms of kilogram force (kgf) of lift reached from the use of the profile by incorporating device (1 1-000) and the first subsystem (12-000) of the present invention in values of minimum lift at 4,000 mosl (B) and values of maximum lift at sea level (C).

Table No. 1

According to the previous example, it was found that lifting generated by only using an aerodynamic profile at sea level and at a speed of 120 km/h reaches a maximum lift of 996.66 kgf, proving that the use of an aerodynamic profile with the system of the present invention comprising device (11-000) and subsystem (12-000) at a speed of 120 km/h under the same above mentioned conditions reaches a minimum lift of 10414.07 kgf and maximum 15946.54 kgf.

With the system of the present invention a weight reduction of the transported load is obtained as was proven in Example 1 wherein lifts between 10414.07 kgf and up to 15946.54 kgf are obtained.

The effect generated by the system at a speed of around 120 km/h at a height of 4000 m over sea level is therefore around 10000 Kg.

Example 2 shows an impact analysis of such effect in view of economic and ecological conditions of load transportation.

In this example the reference is an articulated truck tractor vehicle Freighliner Cascadia having an engine Detroit DD15 and contaminant emissions standard Euro IV was considered.

The emissions mean for Diesel was used as statistical data, as this is the type of fuel more used commercially for this type of vehicle, today.

• Diesel: 2,61 kg of CO2/liter

It was found that with one of the embodiments of the invention showing the system (device (11-000) and subsystem (12-000)) a reduction in contaminant emissions of around 11 to 13% was obtained compared with vehicles without the system of the present invention such as shown in the following table 6.

Emissions as a function of traveled distance vary depending of multiple factors, such as for example the characteristics of the vehicle, allowed speed and road morphology. T able 6 shows emision factors (g CO2/km).

Table No. 6

Note: All above data were obtained from Cataluna Office for the weather change, practical guide for greenhouse effect emission gases computing.

A: Refers to the vehicle with the system of the present invention.

AD: Refers to the vehicle without the system of the present invention.

B: Refers to the vehicle with the system of the present invention

BD: Refers to the vehicle without the system

Table 6 shows vehicle A and vehicle B, which move in a route carrying different weights and traveling at a constant average speed in three different sceneries:

Urban speed (12 km/h)

Intermediate road speed (54 km/h)

Highway speed (84 km/h)

The results in Table 6 show the following conclusions:

For an average speed of 84 km/h, the system of the present invention allows 11 % emission reduction (gCO2/km) of articulated vehicle B compared with vehicle BD which does not have the system of the present invention.

For an average speed of 84 km/hora, the system of the present invention allows 13% reduction of emissions (gCO2/km) of vehicle A compared with vehicle AD which do not have the system of the present invention.
