Electric control integrated system of carburetor

Abstract

The invention is characterized by integrating a core execution unit in an electric control system of a carburetor of a motor vehicle, namely a duty ratio electromagnetic valve, with the carburetor, and carrying out relevant modification to the carburetor structurally to form a novel electric control integrated system of the carburetor. The system comprises an electronic controller (ECU), the duty ratio electromagnetic valve, a desorption electromagnetic valve, a magnetor trigger signal wire, an oxygen sensor, an intake air temperature sensor, a cylinder end temperature sensor, the novel carburetor after change, an assistant air faucet, a muffler with catalyst (catalytic muffler), an air cleaner, relevant wire harnesses and pipelines, and the like. The system can conduct higher-precision and higher-efficiency adjustment and control on the air-fuel delivery ratio of the engine of the carburetor, thus improving the work reliability and stability of the system, and remarkably achieving the effect of reducing and controlling the exhaust emission of the motorcycle, which can achieve above European three-emission standards. In addition, the work noise of the duty ratio electromagnetic valve in the system is also greatly reduced.

Description

technical field [0001] The carburetor electronic control integrated system integrates the electronic control unit and the carburetor, and uses the mechatronics technology to form a new carburetor electronic control integrated system. Background technique [0002] Usually, the fuel supply curve of a carburetor motorcycle is determined by the carburetor configuration. From the analysis of the carburetor fuel supply curve, the ideal fuel supply volume and air-fuel ratio of the carburetor only account for about 40% of the engine design speed range. However, the fuel quantity and the air-fuel ratio in the speed range of more than 60% of the working process of the engine are in a non-ideal state of being too rich or too lean, resulting in problems such as excessive fuel consumption and exhaust emissions. [0003] In order to improve the above problems, an electronically controlled gas supply system device has been used (see attached Image 6 ). The electronic control air supply s...

AI Technical Summary

Problems solved by technology

However, there are still problems that the working efficiency of the system device needs to be improved, and the working noise of the air supply solenoid valve needs to be further reduced.

Moreover, this set of system devices cannot solve the problem that motorcycles meet the emission standards above Euro III
