Methanol engine capable of improving thermal efficiency

Abstract

The invention provides a methanol engine capable of improving the thermal efficiency. The methanol engine is applied in the technical field of new energy vehicles. A fuel nozzle (3) is arranged at theposition of a cylinder (2) of a methanol engine body (1) of the methanol engine capable of improving the thermal efficiency, the fuel nozzle (3) communicates with a methanol storage box (5) through amethanol supply pipeline (4), a throttle valve (10) of the engine body (1) communicates with a buffer tank (7) through a hydrogen supply pipeline (6), the buffer tank (7) communicates with a hydrogenproduction component (8), and the hydrogen production component (8) communicates with an exhaust pipe of the engine body (1) through an exhaust gas supply pipeline (9). The methanol engine capable ofimproving the thermal efficiency is simple in structure, the problem of engine cold start difficulty is effectively solved, reformed gas is mixed with air before the throttle valve and then enters the engine for mixed burning after the engine temperature rises, the methanol fuel thermal efficiency is improved, and the overall performance of the engine is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and more specifically relates to a methanol engine with improved thermal efficiency. Background technique [0002] At present, methanol engine is a research and development hotspot in the field of energy vehicles. Automobile manufacturers have launched 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 r...
