Gasoline premixing and diesel igniting engine as well as control method thereof

Abstract

The invention discloses a gasoline premixing and diesel igniting engine as well as control method thereof. The gasoline premixing and diesel igniting engine includes a diesel engine and a main control unit for controlling the action of the engine, wherein a control signal output end of the main control unit is connected with the diesel engine, at least one gasoline injector is arranged on an air inlet pipeline of the diesel engine, and the gasoline injectors are connected with a gasoline electronic pump through a gasoline common rail; the control method is as follows: the main control unit receives information acquired by an information acquisition unit; and further, the main control unit judges the working condition of the engine as per various received information, and selects corresponding ignition mode to start the engine. The gasoline premixing and diesel igniting engine has simple structure and low cost, only requires arrangement of multiple gasoline injectors on the air inlet pipeline of the existing diesel engine, and meanwhile, can efficiently lower the oil consumption and reduce emission of harmful substances. The gasoline premixing and diesel igniting engine is applicable to engines used in fields of automobiles, locomotives, steamships, farm machinery, engineering machinery and the like.

Description

technical field [0001] The invention belongs to the field of automobiles and relates to an engine, in particular to a gasoline premixed diesel ignition engine and a control method thereof. Background technique [0002] At present, since the internal combustion engine is the prime mover with the highest thermal efficiency and the largest power per unit volume and unit weight, the internal combustion engine is still the most commonly used power device at present. Because internal combustion engines use oil as fuel, the oil content in the world has long been declining, especially in my country, where the oil content is not high, and with the continuous increase in mining, the existing oil in our country is getting less and less, so now our country Imported oil is used to meet the needs of production and life. According to statistics, in 2006, my country's dependence on oil imports has reached 47%, of which, the oil consumption of internal combustion engines accounts for more th...

Problems solved by technology

[0004] In view of the above-mentioned environmental pollution problems, internal combustion engines need to rely on "exhaust gas purification equipment". With the continuous improvement of emission requirements, after-treatment equipment has become more and more complicated, and the corresponding prices are also rising. Currently, the best The cost of aftertreatment equipment accounts for about 40-90% of the original engine cost

In particular, post-processing equipment often needs to consume a large amount of precious metals, and the world's precious metal resources are very limited, thus causing a shortage of precious metal resources and an increase in costs
