Abstract: Economy of engine operation depends on combustion quality of fuel. When engine degree of compression is increrased, conditions for mixture preparation in cilinders are improved. Due to that, CO and CnHm are reduced in combustion products, specially when engine workload is not high. However, increase of compression degree results in increase of burning temperature as well as the amount of NOx in combustion products. The range of diesel engine workload and velocity is wide in operating conditions. Air surplus coefficient is very uneven (approximatelly it is about 1,3-5,0). It looks like air is enough for fuel to be burnt completely. However, the amount of CO and CnHm in combustion products does not depend on mixture composition, but it is of a local character - air deficitis felt in flame front and near the walls of a combustion chamber. Due to this reason the this component was introduced into the analysed fuel - dehidrated ethanol. It ensures a larger amount of oxygen during burning process. The research made proved, that emission of combustion products and minutely changed performance allow considering this fuel to be a serious alternative to fuel of mineral nature
