Which outcome results when a diesel engine operates with excessively retarded fuel injection timing?

💡 Explanation

When fuel injection is retarded, combustion occurs later in the expansion stroke because less time is allowed for heat release near top dead center leading to higher exhaust temperatures. Therefore increased exhaust valve temperatures result, rather than reduced peak pressures, elevated fuel consumption, lower power which require earlier injection timings.
