Title:
GASOLINE ENGINE WHOSE DEGREE OF COMPRESSION IS EQUAL TO OR LESS THAN 45
Document Type and Number:
WIPO Patent Application WO/2005/111396
Kind Code:
A1
Abstract:
The inventive gasoline engine whose degree of compression is equal to or less than 45 comprises a crankshaft provided with a rotation velocity sensor thereof, an intake manifold provided with a throttle gate and an electronic control unit (ECU). Said engine also comprises a vacuum pump with a drive and the vacuum pump input coupled with the engine intake manifold, wherein the vacuum pump drive and the throttle gate drive are connected to the electronic control unit outputs. Said electron control unit produces signals for the vacuum pump drive for the activation thereof after ignition is switched-on, thereby removing air from the intake manifold when a fuel injection device and the throttle gate are closed. When a specified vacuum level is attained in the intake manifold, the electronic control unit forms a signal to a starter for turning the crankshaft. Said invention makes it possible to improve the engine ignition reliability and enables the engine to turn at peak revolution.
