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.

Abstract

The invention relates to an ECU of an electronic control work system of a motorboat with a gasoline engine; the ECU consists of an input circuit used for connecting a sensor section, a singlechip CPU, a memory ROM, a RAM and an output circuit used for connecting an actuator section; two ends of the singlechip CPU are connected with the input circuit and the output circuit, and the memory ROM and the RAM are connected with the singlechip CPU; The ECU includes an oil injection interrupting control program and a non-accelerator state control program; the ECU is the core part of the engine control system of the motorboat; the ECU can provide the gas mixture with the optimum air fuel ratio and the optimum ignition time for the engine according to different working conditions, thus the engine can be in the optimum working state all the time, and the motorboat can have 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 a motorboat with a gasoline engine, in particular to an ECU for an electronic control working system of a motorboat with a gasoline engine. 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...
