The operation of a large two-stroke marine diesel engine during fire in the scavenging air receiver was investigated through simulation. A detailed performance prediction code for reciprocating engines was used, extended with a model capable of simulating fires in scavenging spaces. Simulation runs of several cases of fire were performed, including the case of a severe fire which caused turbocharger compressor surging and flow reversal. The case of engine slow-down during a severe fire was also examined revealing that, under certain conditions, the engine cannot be stopped. By analysing the simulation results, an insight into the effects of fire in the scavenging space on the operation of the engine and turbocharger was obtained.
