A diesel engine including a technique for limiting the fuel value injected into each cylinder so that overfueling does not occur. A fuel value limit is calculated based on ambient temperature and pressure, fuel temperature, fuel heating value and the conditions of the fuel pump and injector. This fuel value limit is compared to the actual fuel value commanded and if the limit is greater than the fuel value commanded, then the engine operation is derated. Alternatively, if the fuel value is below the calculated limit, then the engine can accept the fuel value without affecting its operation.

1. An internal combustion engine, comprising:a cylinder including a combustion space; a fuel system for injecting a fuel value into said combustion space in response to the engine load; a controller for determining a fuel value limit for the cylinder in response to one or more engine operating conditions; and wherein said controller controls the fuel system to inject a fuel value that does not exceed said fuel value limit.
