Accelerator Stroke Adjusting Device for Compression Ignition Mixed Fuel Engine

Abstract

The invention relates to the field of engine throttle control devices, and particularly discloses a throttle stroke regulation device of a compression-ignition-type mixed fuel engine. The device comprises an electromagnetic valve, a cylinder body connected to the electromagnetic valve, a piston arranged in a center hole of the cylinder body, two piston ejection rods extending out of the cylinder body from the two ends of the piston and a sliding regulation rod arranged on the outside of the cylinder body, wherein the two ends of the sliding regulation rod are connected with the ends, away from the cylinder body, of the piston ejection rods respectively. The two sides of the bottom of the cylinder body are respectively provided with an air in-out nozzle, the electromagnetic valve is linked to the cylinder body through the two air in-out nozzles, the two ends of the cylinder body and the two sides of the sliding regulation rod are correspondingly provided with limiting devices, and the sliding regulation rod moves horizontally relative to the cylinder body under the pushing action of the piston ejection rods. On the condition that a throttle pedal stroke is not changed, maximum oil supply amount of a throttle is limited in a linear mode, and the engine throttle control device is mainly used for meeting operation control requirements of the engine when the mechanical compression-ignition-type engine converts between a single fuel combustion mode and a mixed fuel combustion mode.

Description

technical field [0001] The invention relates to the field of engine throttle control devices, in particular to a throttle formation regulating device for a mixed fuel engine. Background technique [0002] In recent years, many vehicles using mixed fuels have appeared. Accurate air supply control is particularly important in mixed fuel engines. Once the accuracy of air supply decreases, it will cause fuel loss and even damage the engine. In the prior art, in order to ensure that the fuel supply of the engine in the co-combustion mode is not greater than the set value, a fixed-point fuel limit mode is usually adopted, that is, the displacement size of the throttle rod is limited. The stroke of the accelerator pedal is reduced by about 50%, thus changing the driver's driving habits, and the control accuracy is greatly reduced due to the vibration of the vehicle. Contents of the invention [0003] The object of the present invention is to propose a throttle stroke adjustment ...
