Abstract
The density of fuel being used by a compression-ignition engine and the flammability of the fuel (readiness to ignite when injected into a combustion chamber of the engine, under the current operating conditions of the engine) are respectively detected. When the flammability is excessively low and the density is above a threshold value, the oxygen concentration of the intake air supplied to the cylinders is increased until the flammability reaches a reference condition, while when the flammability is excessively low and the density is below the threshold value, the compression ratio of the engine (and/or each pilot injection amount) is increased until the flammability reaches the reference condition.
