Title:
METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/105876
Kind Code:
A3
Abstract:
The invention relates to motor construction and specifically to internal combustion piston engines. The technical result of the invention consists in using a fuel with a low octane number, reducing the specific fuel consumption at minimum speeds and during idling, and also producing a maximum output power and torque at maximum speeds. On medium and maximum loads, air is fed into the combustion chamber by a compressor, and in the idling mode and on low loads, the compressor drive is disconnected from the engine shaft, and a feed of air into the combustion chamber is performed by creating a pressure drop between the atmosphere and the combustion chamber. The temperature and pressure of the compressed air fed by the compressor and the operating conditions for the compressor are regulated by changing the transmission ratio between the engine shaft and the compressor drive by means of a continuously variable variator. The compressor drive is additionally connected to the transmission shaft of the motor vehicle with the aid of a controllable clutch, and on low loads the controllable clutch of the compressor drive with the transmission shaft of the motor vehicle is left switched on. The air fed into the combustion chamber is additionally compressed in the compressor, which is driven by the energy of the products of combustion.
