Problems solved by technology

This method has a good fuel-saving effect and is easy to use. The disadvantage is that it increases the labor intensity and wears out the release bearing of the clutch, which increases the failure rate and thus increases the operating cost of the car. No power generation during taxiing and no air conditioning

Abstract

The invention discloses a variable circulation control system for an automobile engine. According to the system, during gear engaging sliding of an automobile, the four-stroke engine can automatically become to passively run in a two-stroke cycle manner. Oil supply of an exhaust gas turbocharger is not interrupted all the time while rotation of the engine is maintained. In addition, when gear engaging accelerated running is converted into sliding, the automobile can have the sliding distance and oil saving effect similar to those of engine flameout neutral position sliding in the state that the automobile keeps the deserved braking performance without neutral position and flameout operation. When gear engaging sliding is converted into the acceleration state, the starting operation can be conducted without the neutral position or stepping of a clutch pedal.

Description

1. Technical field [0001] The invention relates to a variable circulation low resistance control system of an automobile engine. The system changes the circulation mode of the automobile engine immediately after the automobile enters the state of sliding in gear, so that the resistance and vibration generated when the automobile engine is in the state of passive rotation are reduced. to minimum. 2. Background technology [0002] At present, when a known vehicle is running, especially a truck, its coasting state accounts for more than 30% of the total running time or mileage of the car. The modes of coasting include: coasting at idle speed and neutral gear, coasting at forced idle speed, coasting with engine off and neutral gear , turn off the engine and slide in gear, turn off the engine and put in gear and step on the clutch to coast. [0003] Each taxi mode has its own drawbacks: [0004] Idling and neutral coasting, the engine runs at idling speed, this method has a lon...
