Embodiment Construction

[0024] 1. Hydrogen fuel internal combustion engine multi-channel hydrogen injection electronic control system

[0025] The hydrogen fuel internal combustion engine multi-channel hydrogen injection electronic control system of the present application includes an electronic control unit ECU 18, and the electronic control unit ECU 18 controls and connects hydrogen injection devices such as Figure 2 to Figure 5 As shown, each hydrogen injector is as close as possible to the intake port according to the engine structure and is evenly distributed along the circumference of the intake manifold, where the angle between each hydrogen injector and the intake manifold is not greater than 45 o The inclination setting, especially 30 o Within is the best, the smaller the inclination angle, the more consistent the flow direction with the intake airflow, which is beneficial to reduce the residence time and quantity of hydrogen gas in the intake pipe, but the size of the inclination angle is ...

Abstract

The invention relates to a hydrogen internal combustion engine (HICE) as well as a multi-path hydrogen injection electronic control system and a hydrogen injection control method thereof. The multi-path hydrogen injection electronic control system of the HICE comprises an ECU (electronic control unit), wherein the ECU controls and is connected with a hydrogen injection device which is connected with an air inlet duct through an air intake manifold; the hydrogen injection device comprises at least two paths of hydrogen injection machines which are adjacent to an inlet valve seat up to the hiltaccording to an engine structure and are uniformly distributed along the circumferential direction of the air intake manifold; the number of the hydrogen injection machines in the hydrogen injection device satisfies the requirement of the full load of the HICE on the hydrogen injection amount; and at least two paths of hydrogen injection machines are determined according to the requirement of thefull load on the hydrogen injection amount, and the hydrogen injection machines are adjacent to the inlet valve seat as far as possible and are uniformly distributed along the circumferential direction of the air intake manifold. According to the invention, the problem that an existing single-path hydrogen injection system can not complete quantitative hydrogen injection within short time can be solved.

Description

technical field [0001] The invention relates to a multi-channel hydrogen injection electronic control system and a hydrogen injection control method of a hydrogen fuel internal combustion engine, and also relates to an internal combustion engine using the system and the hydrogen injection method. Background technique [0002] With its unique advantages in energy and environmental protection and its good performance in vehicles, hydrogen fuel is considered to be the most promising leading fuel for future vehicle engines, and developed countries attach great importance to it. Due to the obvious difference in the physical and chemical properties of hydrogen fuel and petroleum fuel, the formation and combustion of the mixture gas in the hydrogen engine is organized by the intake pipe type low-pressure hydrogen injection system, which is more prone to pre-ignition and backfire. Different from the abnormal combustion of traditional petroleum fuel engines, such as the early ignitio...
