Optimising at least the composition or quantity of air-fuel mixture fed to IC engine combustion chamber or the ignition of the mixture

摘要

The method involves determining whether the engine should be partially heated during the rest phase. The composition or quantity of the delivered mixture or its ignition is controlled depending on the measurement result. The measurement step determines whether the engine should be heated by a separate heating device. The separate heating device is a heat source which acts upon the engine block.
