Description

Single cylinder engine intake elbow

technical field

The utility model relates to an intake elbow of an engine, in particular to an intake elbow of a single-cylinder engine which can be equipped with a fuel injector.

Background technique

At present, the intelligent engine management system has been widely used in the field of automobiles, but there are few mature solutions on motorcycles. Because the scooter itself has less effective space, it is difficult to arrange the fuel injection system, and because the engine itself is running Such vibration is relatively large, how to use the limited space to arrange the fuel injection system and ensure a strict fuel injection angle has become a breakthrough point for the realization of the engine intelligent management system.

Utility model content

The purpose of the utility model is to overcome the above-mentioned shortcomings, and provide a single-cylinder engine intake elbow that can be equipped with a fuel injector.

The technical scheme of the utility model is: a single-cylinder engine intake elbow, including an intake elbow body, a fuel injection nozzle seat is arranged on the intake elbow body, and a seat hole is provided at one end of the fuel injection nozzle seat. The other end is provided with a fuel injector cap fixing platform, and a bolt hole is provided on the fuel injector cap fixing platform; an inclined hole on the inner wall is provided under the seat hole to make room for the sprayed oil beam, and a nozzle cap fixing platform is also provided. There are limited holes, and the centers of the limited holes, seat holes and bolt holes are on a straight line.

The beneficial effects of the utility model are: effectively solve the limitation of space, ensure that the installation of the fuel injection nozzle does not interfere with other parts, so that the engine can ensure an accurate fuel injection angle under any working conditions, and then ensure accurate fuel injection volume and Homogeneous gas mixture.

Description of drawings

Fig. 1 is the structural representation of the utility model,

Fig. 2 is a structural schematic diagram of the inner wall of the seat hole of the utility model.

In the figure: 1 air elbow body, 2 fuel injector seat, 3 seat hole, 4 fuel injector cap fixing platform, 5 bolt hole, 6 inclined hole on the inner wall, 7 limit hole.

Detailed ways

as the picture shows.

An intake elbow for a single-cylinder engine, comprising an intake elbow body 1, an oil nozzle seat 2 is arranged on the intake elbow body 1, and a seat hole 3 is provided at one end of the oil injection nozzle seat 2, and a seat hole 3 The fuel injector is installed on the top, and the other end is provided with a fuel injector cap fixing platform 4, and a bolt hole 5 is provided on the fuel injector cap fixing platform 4, and the bolt hole 5 is used to connect the fuel injector cap; since the seat hole 3 is For downward sloping, the lower inner wall has obvious edges and corners, which is prone to wet wall phenomenon and affects the fuel injection volume. Therefore, there is an inclined hole on the inner wall below the seat hole to make room for the sprayed oil beam, which can avoid wet wall phenomenon; The fixed table 4 is also provided with a limit hole 7, the centers of the limit hole 7, seat hole 3 and bolt hole 5 are on a straight line, passing through three points and one line to prevent the nozzle cap from rotating.

The utility model ensures that the installation of the fuel injector does not interfere with other components under the premise of utilizing limited space, and uses the limit hole 7 to prevent the rotation of the fuel injector cap to ensure accurate fuel injection angle and fuel injection volume, and realize engine management The fuel injection of the system enables the engine to obtain a mixture of reasonable air-fuel ratio under various working conditions, so as to reduce emissions and reduce fuel consumption.

Claims (2)
