Electric-controlled work system for motorboat with petrol engine

Abstract

The invention provides an electronic control work system of a motorboat with a gasoline engine, comprising an air intake system, a fuel oil supply system, an ignition system as well as an electronic control system; the electronic control system consists of a sensor section, an electronic control unit ECU and an actuator section, wherein the sensor section includes a throttle position sensor and an intake pressure and temperature sensor which are arranged on an intake pipe of an intake system, a camshaft position sensor, a coolant temperature sensor and an engine oil pressure switch signal and crankshaft position sensor which are arranged on the engine as well as a tail gas thermo-switch signal and direction column position sensor and a capsizing switch sensor which are arranged on an exhaust pipe of the engine, and the components of the sensor section are all connected with the ECU; the actuator section consists of an electric fuel pump, an oil sprayer, an idle valve and a fault indicating lamp; the components of the actuator section are all connected with the ECU, and the ECU includes a non-accelerator control program and an interrupting control program; furthermore, the electronic control work system has good power performance, fuel economy and emission performance.

Description

technical field [0001] The invention belongs to the technical field of engine automatic control, and relates to an automatic control device for gasoline engine motorboats, in particular to an electronic control working system for gasoline engine motorboats. Background technique [0002] As we all know, the traditional motorboat engine uses a carburetor as its gasoline atomization device. Like the traditional carburetor-type engine car, because the carburetor-type engine does not implement intelligent control of the combustion process of fuel in the cylinder, Cause its gasoline to burn incompletely, not only waste gasoline, what is more serious is that waste gas emission is more serious, pollutes atmosphere. To solve this problem, the use of electronically controlled gasoline injection technology is a more effective way. In recent years, the use of ECU to realize electronically controlled gasoline injection technology has been rapidly applied in the field of automobile engin...

Problems solved by technology

In addition, the existing motorboats and other boats do not have brakes. If you are not sure whether you can stop the motorboat before hitting an obstacle, you need to increase the accelerator and change the direction.
