Motorcycle electric injection intake manifold

Abstract

The invention provides a motorcycle electric injection intake manifold. The motorcycle electric injection intake manifold comprises a manifold body, an oil injector, an oil inlet cap, a T-MAP, an annular sealing ring and a split washer. The manifold body is provided with an air inlet hole, an oil inlet hole, a T-MAP hole, an oil outlet hole and an annular sealing groove which communicate with oneanother; the working end of the oil injector extends into the oil inlet hole, the oil inlet cap is arranged at the other end of the oil injector, and a connecting lug is matched with a connecting protrusion of the manifold body; the working end of the T-MAP extends into the T-MAP hole; the annular sealing ring is arranged in the annular sealing groove in a nested manner; and the split washer is connected with an oil injector ring groove in a clamped manner and fixedly matched with the manifold body through the oil inlet cap. By additionally arranging the T-MAP, the intake air temperature and pressure can be accurately detected and fed back to an ECU to achieve the optimal oil and air mixing; and by arranging the annular sealing ring, the split washer and an anti-rotation structure, it is guaranteed that the oil inlet cap is firmly and reliably installed, and it is guaranteed that an oil injection curve of the oil injector does not change. The overall structure is simple and compact, and manufacturing is convenient.

Description

technical field [0001] The invention belongs to the technical field of motorcycle engine equipment, and in particular relates to a motorcycle electric injection intake manifold. Background technique [0002] The EFI intake manifold is a device that initially mixes air and fuel in the motorcycle EFI system, and is one of the important components of the engine fuel system. The EFI intake manifold, also known as the engine intake pipe, is connected to the engine block and is used to connect the engine intake. [0003] With the implementation of the National IV standard, most domestic motorcycles have begun to develop EFI motorcycles. There is an important component in the motorcycle EFI system, namely the intake air temperature / pressure sensor (T-MAP for short). The main function of T-MAP is to feed back the detected intake air temperature and pressure to the ECU, and the ECU synthesizes other feedback signals to determine the instantaneous operating conditions of the engine,...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned EFI intake manifold has the following defects: the space of the motorcycle is small, and some models cannot arrange T-MAP electronic integrated components on the throttle valve; in addition, the throttle valve repeatedly moves between fully closed and fully open A vortex will be formed when the pressure is high, causing the intake pressure near it to be unstable, which is quite different from the actual intake pressure, and the detection value of T-MAP will be distorted.
