Vehicle engine deceleration and decompression device

Abstract

Vehicle engine deceleration and decompression device, the decompression device includes a drive mechanism and a push rod, one end of the push rod is fixed in the drive mechanism, and when the push rod is extended, the other end touches against the engine valve. The upper end surface of the rocker arm; the drive mechanism controls the telescopic movement of the push rod. The decompression device of the present invention reduces the running resistance of the cylinder piston of the engine when the engine is dragged backwards by the vehicle during the forward process of the vehicle, slows down the tendency of the engine speed to decrease, and prolongs the sliding distance of the vehicle when the engine is rotated backwards. The decompression method when the vehicle engine is running in the present invention uses the electronic control unit in the vehicle to judge the running state of the vehicle through the information of each sensor, so as to perform the decompression action on the vehicle engine, so that the vehicle is dragged backwards under the set state The sliding distance when the engine is rotating is extended, which has practical value.

Description

technical field [0001] The invention relates to a vehicle engine deceleration and decompression device. Background technique [0002] When the vehicle accelerates to a certain speed, the engine speed must be higher than the engine speed when the engine is idling. At this time, if the driver releases the accelerator pedal, the fuel supply system in the engine will be in the state of idling, that is There is no human control of the fuel supply system or accelerator. At this time, the speed of the engine will be dragged backward by the vehicle, and the speed of the engine will decrease with the speed of the vehicle. One end of the engine rocker arm contacts the engine valve. During this process, the valve opens and closes as the engine rocker rotates. When the valve is closed, the running resistance of the piston in the cylinder becomes larger, which makes the engine speed drop faster, resulting in a shorter gliding distance of the vehicle. Contents of the invention [0003...

At this time, the speed of the engine will be dragged backward by the vehicle, and the speed of the engine will decrease with the speed of the vehicle. One end of the engine rocker arm contacts the engine valve. During this process, the valve opens and closes as the engine rocker rotates. When the valve is closed, the running resistance of the piston in the cylinder becomes larger, which makes the engine speed drop faster, resulting in a shorter gliding distance of the vehicle.
