An important task while operating motor vehicles is to maintain the necessary oil temperature in its units, where various heating techniques and modules are used. Recently, researchers observe the heat capacity from exhaust gases of internal combustion engines (ICE). The use of the ICE for researches on necessary design parameters of oil heating systems is quite expensive. Current research deals with the design of the simulating exhaust system module for the KamAZ vehicles with forming a gas flow at a temperature close to the temperature of the ICE exhaust gases. The simulating module provides imitation of the engine operations in idle mode (engine crankshaft speed n = 800 min-1). The main units and parts of the simulating module are the fuel tank, fuel pump, injector, ignition system, supply fan, combustion chamber, intake pipe, thermocouple, electronic converter with digital display and muffler. It was found that the temperature of gases at the combustion chamber outlet of the simulating module with the fuel pump pressure of 0.35 MPa and an air flow rate of the supply fan of 6.5 m/s, is in the range of 420±15 ℃ and corresponds to the temperature of the exhaust gases in the KamAZ 740 engine. The results of the current research proved the efficiency of the designed simulating module in exploring oil heating systems in transmission units.
