Research has been carried out on feasibility of using biomethanol as a fuel in diesel engines converted for work on spirits, compared to usage of diesel fuel of petroleum origin. For realization of these tasks at Department of Automobile Transport in IFNTNG was converted for work on methanol automobile diesel engine of model XI7DTL OPEL. To convert the diesel engine to methanol compression strength of the engine was reduced to 14.1 by installing of additional gaskets under the head of cylinder block, an original microprocessor DIS ignition system of own design was installed, and engine management system was optimized. Experimental dependences of effective power and specific fuel consumption on the crankshaft rotational speed for the original diesel engine and converted for methanol diesel engine have been investigated. It is established that transferring diesel engine for work on methanol it is possible to achieve power indexes of original one. Analysis of exhaust gases during transferring of diesel engine to work on methanol shows that in all modes of engine there is a significant reduction in emissions of nitrogen oxides and carbon monoxide.
