Abstract

The invention provides a methanol-diesel oil dual-fuel engine and a rail locomotive. The methanol-diesel oil dual-fuel engine comprises: a diesel oil engine, a methanol injection system and an electronic control system; the methanol injection system comprises: a methanol tank connected through a primary methanol pump and a methanol nozzle mounted at a combustion chamber; a controller of the electronic control system controls injection starting time and injection mass of methanol according to acquired rotating speed of the engine, throttle opening and water temperature. The rail locomotive is provided with such a methanol-diesel oil dual-fuel engine. According to the methanol-diesel oil dual-fuel engine and the rail locomotive provided by the present invention, the injection starting time and injection mass of the methanol are controlled according to the rotating speed of the engine, the throttle opening and the water temperature, and therefore, the methanol and the diesel oil do not need to be premixed by adding a co-solvent and the cost of the fuels is reduced.

Description

technical field [0001] The invention relates to a methanol-diesel dual-fuel engine and a rail locomotive, belonging to the technical field of rail vehicle manufacturing. Background technique [0002] In recent years, as energy issues and environmental issues have become more and more prominent, energy conservation and environmental protection have become the focus of engine research and development. Therefore, the methanol-diesel dual-fuel engine that can effectively protect the ecological environment and has good economy has become the key to engine research and development. [0003] The methanol-diesel dual-fuel engine in the prior art uses the existing diesel engine. After adding methanol and a co-solvent to the diesel oil to make the methanol and diesel oil miscible, the mixture is sprayed into the combustion chamber of the cylinder through the diesel nozzle and ignited. . [0004] But the realization process of this methanol-diesel dual-fuel engine needs to add a larg...
