Trigger signal control engine decompression device

Abstract

The invention relates to a trigger signal control engine decompression device. The device comprises a control chip, a relay, a throttle position switch and a motor, wherein when an engine works, a signal of a trigger and a signal of the throttle position switch are input into the control chip in a balance mode, or when the throttle position switch is turned off, namely in a normal acceleration state, the control chip determines that the engine normally works and does not send any instruction, and the motor stops working; and under the condition that the engine is decelerated, namely when the signal of the trigger is higher than 1,200rpm and the throttle position switch is turned on, the control chip sends a signal to the relay, the relay is operated, the motor pushes a gas inlet valve to move downwards, compressed gas of the engine is completely discharged from the gas inlet valve, and the engine loses compression pressure and stops working, so that the sliding distance of a vehicle is increased, the suction of fuel oil is stopped, a carburetor engine can save oil by over 10 percent, and an obvious effect is achieved.

Description

technical field [0001] The invention relates to a motor vehicle engine compression and decompression device, in particular to a trigger signal control engine decompression device. Background technique [0002] Gasoline internal combustion engines generally use carburetors to supply oil, which accounts for the vast majority. This mechanism has a simple structure and is easy to maintain, but it has obvious shortcomings: the vehicle needs to constantly change the opening angle of the accelerator under different road conditions to change The speed of the engine, when transitioning from high speed to low speed, the throttle valve is loosened to the lowest position, but the speed of the engine is greater than the opening of the throttle valve, and the strong negative pressure generated by the throat makes the carburetor idle nozzle and main nozzle The fuel injection volume of the scooter is several times higher than the normal value, resulting in unnecessary fuel consumption of th...

[0002] Gasoline internal combustion engines generally use carburetors to supply oil, which accounts for the vast majority. This mechanism has a simple structure and is easy to maintain, but it has obvious shortcomings: the vehicle needs to constantly change the opening angle of the accelerator under different road conditions to change The speed of the engine, when transitioning from high speed to low speed, the throttle valve is loosened to the lowest position, but the speed of the engine is greater than the opening of the throttle valve, and the strong negative pressure generated by the throat makes the idle nozzle of the carburetor and the main nozzle The fuel injection volume is several times higher than the normal value, resulting in unnecessary fuel consumption of the engine. At the same time, especially for scooters, due to the compression resistance of the engine, the sliding distance is short, the temperature rises high, and it is easy to wear and other disadvantages.
