Abstract

The invention provides a methanol fuel engine applied to the technical field of new energy cars. A hydrogen nozzle (3) of an engine body (1) of the methanol fuel engine communicates with a hydrogen storage tank (4), a methanol water solution tank (7) communicates with a methanol water steam reforming hydrogen production reactor (6), an exhaust pipe of the engine body (1) communicates with a wasteheat recycling device (5) which communicates with the methanol water steam reforming hydrogen production reactor (6), and the hydrogen storage tank (4) communicates with the methanol water steam reforming hydrogen production reactor (6). The methanol fuel engine is simple in structure, engine tail gas during engine work is used, methanol water solution online hydrogen production is achieved, the prepared hydrogen serves as fuel to be supplied to the engine to work, when the engine is started, the problem of difficult cold starting of the engine does not exist, meanwhile, engine heat efficiencycan be improved, and clean combustion is achieved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and more specifically relates to a methanol fuel engine. Background technique [0002] At present, methanol engine is a research and development hotspot in the field of energy vehicles. Automobile manufacturers have introduced methanol vehicles. Methanol vehicles have the advantages of energy saving and emission reduction, and also have advantages in terms of economy. Methanol is a renewable resource, so that the energy of automobiles no longer relies solely on fossil fuels. However, methanol cars have a disadvantage: cold start is difficult. The reasons are as follows: the calorific value of methanol is lower than that of gasoline, and more methanol vapor is required for combustion; the latent heat of vaporization of methanol is high, and more heat is required for evaporation; the ignition point of methanol is higher than that of gasoline; The air-fuel ratio is higher than that o...
