Study On Direct Injection Diesel Engine With Additional Injection Of Liquid Or Fuel Containing Hydroxyl

The energy and environment are two important problems existing in the development of human society. More and more energy is needed and the environment protection becomes more and more important. Due to petroleum crisis and the vehicles emissions that have done a great harm to human's health in the world, the dominance of gasoline and diesel used as the fuel in vehicle engines must be diverted into more kinds of fuel in the future. The kinds of fuel be used quickly or slowly, which firstly depends on petroleum shortage and exhaustion or not, secondly depends on the development sophistication of the engine energized by various kinds of alternative fuels, thirdly depends on degree of pollution from the alternative fuel engines. The petroleum oil shortage and emission regulations are getting stricter. Except traditional gasoline and diesel fuels, engines must use more clean fuels and some other fuels that emit less pollution. Developing more kinds of fuel for diesel engines, we should find out virtues and defects of fuel used in diesel engines, add to virtues and correct defects, diesel engine can use different fuel when diesel engines have a little reform. To reduce petroleum import from other countries, we shouldn't count on petroleum import. It is a good method that is in keep with our country, and is advantageous to growing of vehicles and petroleum industry as well.The key to Study fuel containing oxygen and hydrogen, or liquid with oxygen and hydrogen on a DI Compression Ignition Engine is to design a DI Compression Ignition Engine with dual Injection systems. On the basis of the T1115 diesel engine, developing work includes how to drive second Injection system, to reform cylinder cap and injector, to control fuel per cycle between the tow injectors, to install sensor of cylinder pressure and grating plate of crank angle measure, to install electric motor and generator for engine starting, to control automatically temperature of cooling water and lubrication oil. The test engine has its characteristics; such as dual Injection systems are synchronism, injection quantity per cycle can be adjusted independence, injection time can be adjusted independence in 0~720°CA, pressure of the cylinder can be measured while fuel burning conveniently. The results prove that the test engine can satisfy the needs of the DI Diesel engine by Additional Injection of liquid with oxygen and hydrogen.The liquid with hydroxyl (HO) be injected into combustion chamber of a DI...
