Abstract

The invention discloses a dual-fuel spraying internal-combustion engine accomplishment method and device of alcohol liquid fuel and fuel oil, which comprises the following parts: at least one cylinder motor, fuel oil spraying device, state detection device, electronic control unit (ECU) and alcohol liquid fuel spraying device, wherein the alcohol liquid fuel spraying device is set on the motor inlet branch pipe of motor and between air throttle and fuel oil sprayer. The invention adapts a combination device of two independent spraying units to control the proportion of fuel oil and alcohol liquid fuel according to the different running condition. When the automobile starts or accelerates, the device will reduce the alcohol proportion. When the load runs stably, the device increases the alcohol proportion to guarantee the motor power output and dynamic property, which affirms the automobile accelerating ability and driving ability.

Description

technical field

[0001] The invention relates to an internal combustion engine, in particular to a method and device for realizing an internal combustion engine using dual fuel injection. Background technique

[0002] Now almost all fuel vehicles use gasoline or diesel as fuel. As we all know, the world is facing the problems of increasing shortage of oil resources, high oil prices and increasingly stringent environmental protection requirements, especially those belonging to the poor. my country, an oil country, is particularly prominent on this issue. For this reason, the use of fuels other than petroleum as fuels or fuel additives for automobiles has become a common concern of the whole society. Alcohols such as methanol and ethanol that have good volatility, high octane number, and can significantly reduce pollutant emissions are used Liquid fuel has become the preferred auxiliary fuel for automobiles. In the current technology, the method of mixing a certain proportion o...
