Problems solved by technology

[0005] The hydrogen / gasoline dual-fuel internal combustion engine can flexibly select gasoline and hydrogen to enter the pure gasoline or pure hydrogen internal combustion engine mode according to the storage conditions of the fuel. Due to the operation of the pure hydrogen mode, the hydrogen consumption is large, and there are few hydrogen refueling stations, resulting in hydrogen / gasoline Dual-fuel engines use pure gasoline most of the time, and gasoline engines have low thermal efficiency and high emissions. It can be seen that the economical and environmental performance of hydrogen / gasoline dual-fuel internal combustion engines is average.

Abstract

The invention relates to a hydrogen-gasoline mixed fuel engine and its control method, which mainly includes an electric control gasoline injection and ignition system and an electric control hydrogen injection and ignition system. The electric control hydrogen injection and ignition system includes a hydrogen injection and ignition control unit, a fuel injection pulse width control module and an ignition angular advance control module. The fuel injection pulse width control module is disposed between the electronic control unit and the fuel nozzle controlled by the hydrogen injection and ignition control unit. The ignition angular advance control module is disposed between the electronic control unit and the ignition module controlled by the hydrogen injection and ignition control unit.

Description

technical field [0001] The invention provides a hydrogen-gasoline mixed fuel engine and a control method, in particular to the control of a combustion engine. Background technique [0002] Environmental protection and transformation of energy structure are the two major themes of the 21st century. Hydrogen fuel, with its unique advantages in energy and environmental protection, is expected to promote the arrival of an economic era marked by it. Hydrogen energy is regarded as the energy source with the greatest potential for development in this century because of its cleanliness, high efficiency, and renewability, and the existing petroleum fuel-burning automobile internal combustion engines can burn hydrogen with a slight modification. In addition, hydrogen fuel also has many advantages when used in automobiles. For example, the calorific value per unit mass of hydrogen is higher than that of gasoline; the flame propagation speed of hydrogen is much faster than that of petro...
