Hydrogen engine

Abstract

The invention discloses a hydrogen engine, which comprises: a cylinder and a hydrogen fuel feeding system. A gas piston is arranged on the top center, i.e. when the crank is in an angle of 90 degrees, there's no space between the top of the gas piston and the cylinder, and when the gas piston runs from the top center to the middle point of the stroke, i.e. the crank is in an angle of 180 degrees, the spark plug is fired and pushes the gas piston to the bottom center; the gas piston runs from the bottom center to the top center to complete the exhaust stoke. A cycle of operation includes the air-in working process and exhausting process. Hydrogen fuel preparation tank is connected to a hydrogen-oxygen mixer via an electrical hydrogen injector with pipes, an air filter is connected to the other port of the hydrogen-oxygen mixer via turbochargers, gas outlets of the hydrogen-oxygen mixer is connected to the inlet port of the gas tank. The hydrogen engine is equipped with a waste gas recycle system and a water-spraying device.

Description

technical field [0001] The invention belongs to power machinery, in particular to a hydrogen engine. Background technique [0002] At present, the hydrogen engine installs a hydrogen supply system on the prototype gasoline engine, uses the air pressure in the hydrogen storage tank to deliver hydrogen to the engine, and uses the traditional four-stroke working method of compression combustion to do work. The advantage of this hydrogen engine is that it can be used with gasoline, but because it still adopts the working mode of compression combustion (combustion is more than explosion), the rotating speed is slow, and it not only fails to make full use of the characteristics of hydrogen explosion to improve the working efficiency of the engine, but also in During the compression process, there are hidden dangers of self-ignition, pre-ignition, and reverse rotation due to the increase in cylinder temperature, resulting in serious failures such as knocking on cylinders and damagi...

The advantage of this hydrogen engine is that it can be used with gasoline, but because it still adopts the working mode of compression combustion (combustion is more than explosion), the rotating speed is slow, not only the characteristics of hydrogen explosion cannot be fully utilized to improve the working efficiency of the engine, but also in During the compression process, there are hidden dangers of self-ignition due to the increase of cylinder temperature to pre-ignition, reverse rotation, and serious failures such as knocking on cylinders and damage to parts.
