Gas electrojet system of two-stroke outboard engine

Abstract

The invention relates to a gas electrojet system of a two-stroke outboard engine, which comprises a gas cylinder, a switch electromagnetic valve, an LPG / CNG gas preheating pressure regulator, a gas common-rail nozzle, an electronic control unit, a throttle valve angular transducer, an idling bypass-valve, a water temperature sensor, a synchronous reference signal sensor, a high-energy ignition system, an oxygen sensor and a ternary catalytic converter, wherein an outlet of the gas cylinder is provided with the switch electromagnetic valve and the LPG / CNG gas preheating pressure regulator; an engine throttle valve body is provided with the throttle valve angular transducer and the idling bypass-valve; an exhaust pipeline of the engine is provided with the oxygen sensor and the ternary catalytic converter; the top of the engine is provided with the high-energy ignition system; the synchronous reference signal sensor is arranged at the position of a cylinder corresponding to a crankshaft; the electronic control unit is used for receiving working condition signals coming from all the sensors, and control signals are output to control the work of the two-stroke gas outboard engine after the working condition signals are processed. The gas electrojet system can improve the output power of the two-stroke gas outboard engine, reduces the consumption of fuel, and minimizes the pollution of the tail gas of the engine for the environment.

Description

technical field [0001] The present invention relates to the technical field of two-stroke gas-fired electric injection engines, and specifically relates to a method for controlling two-stroke gas-fired outboard motors to ensure accurate ignition advance angles and fuel injection volumes of the engines in various working conditions, so that the two-stroke gas-fired outboard The two-stroke outboard motor gas electric injection system has a high output power of the outboard motor, reduces fuel consumption, and minimizes the pollution of the engine exhaust to the environment. Background technique [0002] The engine is a device that provides power, and its function is to burn the fuel supplied to it to generate power. The engine is divided into gasoline engine, diesel engine and gas engine according to the fuel used. According to the number of strokes to realize the cycle, it is generally divided into two categories: four-stroke engines and two-stroke engines. [0003] For eve...

AI Technical Summary

Problems solved by technology

Most of the existing gas outboard motors are four-stroke gas outboard motors, but four-stroke gas outboard motors have complex structures, high failure rates, difficult maintenance and low output power, high equipment replacement and use costs, and poor cost performance
