Findings of the Research of Operating Conditions of Internal Combustion Engines of Fire Vehicles
Results of the researches of a technical condition of cylinder-piston groups of power-generating sets of fire vehicles in cold and warmed up to optimum temperatures condition are given in this work. It is experimentally proved that compression of engines both in their "cold", and "hot" condition decreases with the increase of degree of their wear. In the process of wear of engines the average value of their compression in "cold" and "hot" condition also decreases. For guarantee of high dynamics duringthe response of fire vehicles to emergencies, it is necessary to provide heating of average and strongly worn outengines during the time a fire vehicle is in the apparatus room or it is necessary to essentially reduce the rate of their cooling.
