Hydrogen engine

Abstract

The invention relates to a hydrogen engine comprising a hydrogen supplying system, an air intake system, an engine body and an exhaust system, wherein the hydrogen supplying system comprises a high pressure hydrogen bottle, a solenoid valve, a first-grade reducing valve, a second-grade reducing valve, a flame arrestor and a connecting pipeline. A hydrogen pressure temperature sensor is arranged in a hydrogen air-rail, an air intake pressure temperature sensor is arranged at the front end of a pressure stabilization cavity of an air intake manifold, and a wide scope oxygen sensor is arranged on an exhaust manifold of the exhaust system, an electronic throttle is arranged at the front end of the air intake manifold, the hydrogen pressure temperature sensor, the air intake pressure temperature sensor and the wide scope oxygen sensor transmit signals to an ECU (electronic control unit). In the hydrogen engine, gasoline is replaced by hydrogen to be used as engine fuel, and CO2 emission is reduced to the maximum extent on the basis of not changing the engine body and not increasing the engine cost, so as to improve the emission level of the engine.

Description

technical field [0001] The invention relates to a hydrogen engine. Background technique [0002] As an important member of the fossil fuel consumption family, automobiles bear unshirkable responsibility for the excessive consumption of fossil fuels and global warming. Traditional gasoline engines can no longer meet the higher emission requirements. At present, automobile companies in various countries are actively developing various forms of new products to meet the increasingly stringent automobile emission regulations. [0003] see figure 1 , the traditional gasoline engine is mainly composed of engine intake manifold 3, intake manifold 4, engine body 1 (including cylinder block, cylinder head, etc.), port injection injector 2, exhaust manifold 5, exhaust manifold 6 and three Element catalyst 7 (Three Way Catalyst, TWC) composition. Among them, the intake and exhaust manifolds are respectively connected with the intake and exhaust manifolds, the intake and exhaust manif...

AI Technical Summary

Problems solved by technology

[0004] In the working process of this traditional gasoline engine, due to the difference in fuel quality, different fuel injection methods and the limitation of the catalytic capacity of the three-way catalytic converter, the fuel consumption and emissions of the traditional engine cannot be further optimized. Crude oil reserves continue to decrease, and the development of traditional gasoline engines will be difficult
