آزمون های موتوری سوخت و نقش شان در ارزیابی کیفی سوخت خودروهای بنزینی و دیزلی

Engine tests have an essential role in optimize, simulate actual operating conditions and evaluation of performance of internal combustion engines fuels. in this tests, standard and special engines are driven under certain conditions and adjustments in determined time. the results used for optimizing of motor fuel formulation and improving of engines efficiency, minimize the engine problems (fuel sediments, soot and injectors fouling), promotion of fuel economy and   reduction of vehicles exhaust emissions. engine tests are designed and defined based on the standards world or factory methods. high costs to inaugurate and enforcement the tests and difficult to prepare and security of spare parts of engines are barriers to their expansion. this paper has been paid to investigate and introducing of engine tests in quality evaluation of fuel of gasoline and diesel vehicles in iran and other parts of the world.
