ABSTRACT:
A diesel engine has a fresh-air intake, an exhaust-gas output, and a cooling system in which a liquid coolant is circulated. This system is provided with an antiexplosion system having an intake flame arrester in the intake and a jacketed exhaust-pipe section connected to the output and receiving exhaust gases therethrough from the engine. The cooling system is connected to the jacketed exhaust-pipe section to cool same and to cool the exhaust gases therein by indirect heat exchange with the coolant. An exhaust-gas heat exchanger is connected through the jacketed pipe section to the output. The cooling system is also connected to the heat exchanger to cool the exhaust gases therein by indirect heat exchange with the coolant. An output flame arrester is connected via another exhaust-pipe section to the heat exchanger for conducting cooled exhaust gas from the exchanger to the arrester. Both of the flame arresters have an arrester housing and at least one plate therein defining a multiplicity of parallel passages of very small flow cross section and a similar output flame arrester. In addition the system has a venturi-type exhaust-gas diluter downstream of the output flame arrester for mixing the cooled exhaust gas with ambient air.
