Embodiment Construction

[0075] figure 1 It is a schematic pipeline connection diagram in which the engine and corresponding devices are connected through corresponding pipelines according to the present invention. figure 2 is a schematic flow chart of the engine starting and / or running method. see figure 2 , the application provides a driving vehicle engine 1 (see figure 1 ) method for starting or / and running, the engine 1 is a compression ignition engine 1, and the method is used to reduce the diesel consumption of the engine 1;

[0076] S100, cracking the first methanol into a hydrogen-rich gas, where the hydrogen-rich gas contains at least hydrogen and carbon monoxide;

[0077] S200, mixing the second methanol, hydrogen-rich gas and diesel;

[0078] S300. Ignite the diesel by compression ignition, and the ignited diesel ignites the second methanol and hydrogen-rich gas to drive the engine 1 to start or / and run.

[0079] see figure 2 , further, the method utilizes the engine 1 (see figure...

Abstract

The invention provides a method for driving a vehicle engine to start or / and operate and the engine, and relates to the field of vehicle engines. The engine is a compression ignition engine. The method is used for reducing the diesel usage amount of the engine and includes the following steps that first methanol is decomposed into hydrogen-rich gas which at least contains hydrogen; second methanol, the hydrogen-rich gas and diesel are mixed; and the diesel is ignited in a compression ignition mode, the ignited diesel ignites the second methanol and the hydrogen-rich gas, and thus the engine isdriven to start or / and operate. The inventor creatively uses the hydrogen-rich gas and the methanol to replace diesel, so that the compression ignition engine such as a diesel engine is driven. Sincethe hydrogen and the methanol generate water after burning, the influences on the environment are small. In addition, compared with the diesel, the hydrogen and the methanol can be easily obtained inthe modes of water electrolysis and the like.

Description

technical field [0001] The invention relates to a vehicle engine, in particular to a method for driving the vehicle engine to start or / and run and the engine. Background technique [0002] The advantages of diesel engines are large torque and good economic performance. The working process of a diesel engine has many similarities with a gasoline engine. Each working cycle also goes through four strokes: intake, compression, power, and exhaust. However, since the fuel used in diesel engines is diesel oil, its viscosity is higher than that of gasoline, and it is not easy to evaporate, but its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition of combustible mixtures are different from those of gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression ignited rather than ignited. When the diesel engine is working, what enters the cylinder is air, and when the air in the cylinder is c...
