Abstract

The invention discloses an idle speed increasing structure for an orthostichous mechanical pump diesel engine. The idle speed increasing structure comprises a cantilever assembly, an idle speed increasing valve and a pull block assembly, wherein the cantilever assembly is fixed on an air suction pipe assembly of the diesel engine; the idle speed increasing valve is fixed on the cantilever assembly; the middle part of the pull block assembly is connected with the cantilever assembly in a rotating mode; a return spring is connected between one end of the pull block assembly and the cantilever assembly; a piston rod of a cylinder of the idle speed increasing valve is pressed against the other end of the pull block assembly; and the pull block assembly is connected with a flameout oil stop cylinder in a rotating mode. The idle speed increasing structure can be arranged on the orthostichous mechanical pump diesel engine easily; furthermore, the idle speed can be adjusted and increased as required; therefore, the idle speed of the orthostichous mechanical pump diesel engine can be increased by 100 to 200 r / min.

Description

technical field [0001] The invention relates to an idle speed raising structure of an in-line mechanical pump diesel engine. Background technique [0002] When the passenger car is idling, the idling speed needs to be increased due to the use of air conditioners. The idle speed of our traditional diesel engine is 600 r / min, at which speed the air conditioner cannot work effectively. [0003] Now the air conditioner is generally directly installed with an idle poppet valve. The idle poppet valve includes a solenoid valve and a cylinder. The air in and out of the cylinder is controlled by solenoid valves. After the solenoid valve is opened, the gas enters the cylinder, and the piston of the cylinder moves forward to push the throttle handle. is increased to increase the engine idle speed. The in-line mechanical pump diesel engine of the passenger car is provided with a flame-out and oil-stop cylinder to control the throttle handle, and the above-mentioned idle poppet cannot ...
