Hydrogen and gasoline dual fuel engine

Abstract

The invention provides a hydrogen and gasoline dual fuel engine. The hydrogen and gasoline dual fuel engine comprises a gas inlet manifold assembly, an engine body, an exhaust manifold assembly, a gasoline supply system and a hydrogen supply system; the terminals of the gasoline supply system are gas channel jet gasoline nozzles arranged on both sides of each gas inlet manifold of the gas inlet manifold assembly; and the terminals of the hydrogen supply system are hydrogen nozzles arranged on both sides of each gas inlet manifold of the gas inlet manifold assembly. In the hydrogen and gasoline dual fuel engine, a set of hydrogen nozzles and a set of hydrogen supply system of the engine are additionally arranged on the different sides of the gas channel jet gasoline injectors of the gas inlet manifolds of the conventional gasoline engine simultaneously. Under the different working conditions of the engine, hydrogen fuel and gasoline fuel can be used selectively, so the use of fossil fuel is reduced and the service life is prolonged, and harmful emissions of the engine is reduced; the engine can meet the increasingly strict automobile emission rule; meanwhile, due to the selective use of the hydrogen and the gasoline, the shortcoming that the power is insufficient due to a low specific heat value of the hydrogen can be restrained effectively.

Description

technical field [0001] The present invention relates to engines, in particular dual fuel engines. 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 new engines 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-way catalytic converter 7 (Three Way Catalyst, TWC). Among them, the intake and exhaust manifolds are respectively connected with the intake and exhaust manifolds, the intake a...
