Problems solved by technology
Although this patent can solve the problem of the same air intake volume of the two cylinders, it still cannot solve the problem of inconsistent base leakage at idle speed caused by manufacturing dispersion, and at the same time, it cannot realize the differential and precise adjustment of the compensation air volume

The invention discloses a mechanical electric jet throttle valve of a double-cylinder gasoline engine. The mechanical electric jet throttle valve comprises a throttle valve body. A left air inlet channel with a left cavity spring sheet and a right air inlet channel with a right cavity spring sheet are arranged on the throttle valve body. The left cavity spring sheet and the right cavity spring sheet are connected by a spring sheet rotating shaft. The left air inlet channel and the right air inlet channel are separately divided into a left front cavity, a left rear cavity, a right front cavityand a right rear cavity by the left cavity spring sheet and a right cavity spring sheet. An idling air channel is arranged in the throttle valve body and between the left air inlet channel and a rightair inlet channel. The left front cavity, the left rear cavity, the right front cavity and the right rear cavity separately communicate with the idling air channel by idling bypass air channels. A flat adjusting head is arranged in the idling air channel. The flat head adjusting head is connected with a steeping motor arranged on the throttle valve body. The mechanical electric jet throttle valvehas the advantages that the physical design is ingenious and application is reliable. Air inlet volumes of the two air inlet channels are guaranteed to be the same, high engine idling stability is achieved, and the low-speed performance of the engine is achieved.
Description
technical field [0001] The invention relates to a double-cylinder gasoline engine, which is characterized in that it is a mechanical electronic injection throttle valve of the double-cylinder gasoline engine. Background technique [0002] At present, due to the cost limitation of the existing motorcycle (general-purpose) gasoline engine, its EFI system can only control a stepper motor to control the air flow of the idle bypass air passage, and arrange a load sensor in a single cylinder to control the intake air volume. Make an estimate. Due to the high working speed of the motorcycle (general purpose) gasoline engine, the conventional throttle body cannot well avoid the mutual disturbance (snatching air) of the intake air of the two cylinders, resulting in uneven intake air of the two cylinders, which makes the work of the two cylinders inconsistent. Ultimately, the idling speed is unstable and the engine's low-speed power is poor. [0003] In CN201635843U, a utility model...
