摘要： The pressure of a combustion chamber is monitored and a pressure history in terms of crank angle, compiled over the compression and expansion phases of the engine for a period following a change from a non-transitory mode of operation to a transitory one. This data is used to derive a variable such as the maximum pressure or the like, the development characteristics of which are used to determine the type of fuel (fuel composition) being supplied. The fuel supply under transitory or both transitory and non-transitory modes of operation is modified in accordance with the fuel type analysis. During engine start-up the initial fuel supply can be modified in accordance with the last recorded analysis data.

摘要： A system and method for controlling a multi-cylinder internal combustion engine includes a plurality of pressure-responsive sensors, each detecting the internal pressure in a corresponding cylinder (or in a corresponding cylinder group), means for determining whether the pressure-responsive sensor for any one of the cylinders (cylinder groups) is malfunctioning on the basis of the readings from the sensors, and means for controlling the ignition timing for each cylinder (each cylinder group) on the basis of the readings from the respective pressure-responsive sensors and retarding by a predetermined retardation offset the ignition timing for any of the cylinders whose associated sensor has failed. The ignition timing of a malfunctioning cylinder is offset by the predetermined offset with respect to the ignition timing for one of the other cylinders (cylinder groups) whose corresponding sensor is operating normally and which has the most retarded ignition timing among such cylinders.
