Study On The Performance And Emission Of 465Q Methanol Engine

The situation of domestic and international resources are introduced, werealized that China are facing huge pressure that petroleum resources fallshortage and environmental pollution are serious at present, therefore differentenergy-saving measures must be taken to make use of available resources in themotor technology. To find new energy resources are active path to solve theproblem that we reduce the excessive dependence of petroleum. Methanol isclean alternative fuel for petroleum that have showed its great latent capacity,thus abundant coal resoUrces can be utilized sufficiently and effectively in ourcountry.The feasibility of the oil-based replaced by methanol is analyzed, thetechnology approach and methods of Methanol having been applied in internalcombustion engine and merits and demerits of this kind of fuel, and thepreponderance of developing fuel methanol in shanxi ,which is a coal province,are summarized. Some problems and opportunities of developing fuel methanolin shanxi are proposed in this paper. Some specific goals expected are laiddown. In order to alleviate the motors' dependence on petroleum, and meet thedemands of the exploitation of energy, the widely used engine of 465Q has beenimproved technologically and experimentally on application of M85 fuel, whichcontain 85 percent of Methanol and 15 percent of gasoline. In the experiment,the constructure of engine has been changed and the relative factors have beenadjusted, and the related experimental research and theoretical analysis on theinfluence on the cylinder by injecting the mixed fuel with M85 Methanol andthe gasoline have been carded on. The results proved that, compared with thegasoline engine 465Q, the methanol engine has many advantages in dynamic,economical, and pollution. The methanol fuel can be used in fixed gasolineengine.When using the mixed fuel with M85 MethanOl and the gasoline, the motiveof the engine is obviously higher than that of the original engine, the maximalpower of the engine is about 2 kw higher than that of the original engine; and themaximal torsion is about 9 N.m higher than that of the original engine. Theeconomy of this engine is obviously superior to that of the original engine, theequivalent fuel consumption of methanol is about 30g/kW.h lower than that ofthe original engine. The advantage on discharging is also very .obvious, and thequantity of HC and CO has been improved,...
