Title:
INTERNAL COMBUSTION ENGINE AND DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/171017
Kind Code:
A1
Abstract:
[Problem]
To provide an internal combustion engine suitable for a hybrid system and capable of preventing a reduction in medium/high-speed horsepower as well as torque, improving fuel consumption, and reducing the environmental load by reducing global warming, for example.
[Solution]
In an intake stroke a piston (14) within a cylinder (1) descends, an intake valve (20) opens, and air is drawn into the cylinder (10). This indrawn air is compressed by an external supercharger (80) and cooled by a cooling device (90), and the flow volume is adjusted by a throttle mechanism (70). In a pressurization chamber delivery stroke the piston (14) rises, a pressurization chamber delivery valve (40) opens, and pressurized air is delivered to a pressurization chamber (60). In a pressurization chamber intake stroke the piston (14) descends and a pressurization chamber intake valve (50) opens, thereby drawing the pressurized air into the cylinder (10) again from the pressurization chamber (60). Subsequently a compression stroke, a combustion stroke, and an exhaust stroke, which are identical to those in a four-cycle internal combustion engine, occur.
