一种氢气汽油双燃料发动机制造技术

本发明专利技术提出一种氢气汽油双燃料发动机，其包括进气歧管总成、发动机本体、排气歧管总成以及供油系统；所述供油系统的终端为气道喷射喷油嘴，其布置于进气歧管总成的每根进气歧管的两侧。其还包括一套供氢系统，所述供氢系统的终端是氢气喷嘴，所述氢气喷嘴也布置于进气歧管总成的每根进气歧管的两侧。本发明专利技术是在传统汽油机的进气歧管气道喷射喷油器的异侧增加一套氢气喷嘴，同时增加一套发动机供氢系统，可以在发动机不同工况下有选择地使用氢气和汽油燃料，不但能减少化石燃料的使用，延长使用寿命，还能降低发动机有害排放物，能满足日益严格的汽车排放法规；同时对于氢气汽油的选择使用，还能有效抑制氢气比热值低而带来的动力不足的缺点。

Hydrogen gasoline dual fuel engine

The invention provides a hydrogen gasoline dual fuel engine, which includes intake manifold assembly, engine body, exhaust manifold assembly and fuel supply system; the terminal oil supply system for port injection nozzle, on both sides of each intake manifold disposed in the intake manifold assembly. The utility model also comprises a hydrogen supply system, wherein the terminal of the hydrogen supply system is a hydrogen nozzle, and the hydrogen nozzle is arranged on both sides of each intake manifold of the air intake manifold assembly. The present invention is the opposite side of fuel injector in the intake manifold of traditional gasoline engine and the addition of a hydrogen nozzle, while adding a hydrogen supply system in the engine, the engine at different operating conditions, the selective use of hydrogen and gasoline fuel, not only can reduce the use of fossil fuels, prolong service life, reduce engine emissions also, to meet the increasingly stringent emission regulations; at the same time for hydrogen gasoline use, power shortage can effectively inhibit hydrogen than low calorific value and bring the disadvantages.
