Abstract

The invention discloses an air intake joint structure of a double-cylinder engine. The air intake joint structure of the double-cylinder engine comprises an air intake joint body which is connected among an air filter, an engine throttle valve and an idling stepping motor; one end of the air intake joint body is provided with a first port communicating with the air filter, and the other end of the air intake joint body is provided with a second port, a third port and a forth port which communicate with the first port and can correspondingly communicate with the engine throttle valve and the idling stepping motor; the second port and the third port are connected with two throttle valve throat openings of the engine throttle valve correspondingly; and the fourth port is connected with an air intake throat opening of the idling stepping motor. By integrating the air filter, the engine throttle valve and the idling stepping motor to form the whole air intake joint structure, the air supply requirement of double cylinders of the engine is met, idling air supplement of an electric injection system is achieved, the whole air intake joint structure makes air intake arrangement compact, the assembling space is saved, air intake of the double-cylinder engine is more smooth, and the air intake joint structure of the double-cylinder engine is quite practical.

Description

technical field [0001] The invention relates to a double-cylinder engine intake joint structure. Background technique [0002] The twin-cylinder engine has two independent combustion chambers and two independent EFI throttle valves. During operation, the gas enters the throttle valves respectively through the air filter through the intake joint, and then flows into the engine block for operation. In general, the air intake connector and throttle valve are all independent structures, and at the same time, the air filter and the air intake throat of the stepping motor are separately connected through a hose to realize the idling air supply of the EFI system. The overall structure is relatively complicated, and for the twin-cylinder engine, the space utilization rate is low, and the overall air intake smoothness of the twin-cylinder engine is poor due to the arrangement of each intake pipeline. Contents of the invention [0003] Aiming at the deficiencies in the above-mentio...
