98. One of the factors limiting the amount of load which can be put on a modern marine diesel engine is the __________.

Excessive exhaust temperature can damage engine components, limiting the safe load capacity of a modern marine diesel. Engine manufacturers specify maximum exhaust gas temperatures to prevent overheating and material failure; exceeding these limits can result in damage to exhaust valves, turbochargers, and other critical parts. Therefore, exhaust temperature is a primary limiting factor on engine load.
