Contrast Experiment Research On Plunger Matching Parts Assembly Of High Pressure Oil Pump Worn By Diesel Fuel And DME-Diesel Blended Fuel

With the attention of environment protection and the increase of the automobile recoverable amount in the world, the engine faces the double pressure of continuing improving existing performance and reducing discharge. The discharge composition of engine has something to do with not only the burning course of engine, but also the fuel of the engine. In order to improve the discharge performance of engine, the most direct method is to use the fuel which generates less harmful discharge. Meanwhile, because of the reduce of the world petroleum resources day by day, people need a kind of new energy to replace it urgently. Therefore, the research of clean alternative fuels have become a advancing front in the internal-combustion engine field.Dimethyl Ether (DME) is the most promising ultra-low-emission alternative fuel discovered recently in the world. It is showed by research that its cetane number is so high that DME is perfectly suitable to be alternative fuel of diesel engine, and it is hopeful meeting the future stringent emission regulation of diesel engine because of its clean...
