摘要： A method is disclosed for detecting misfire or partial burn and for controlling spark retard in the cylinders of an internal combustion engine operated under the control of a microprocessor and utilizing signals indicative of the pressure in said cylinder at crank angle positions before and after initiation of combustion. A ratio of the actual pressure to the motored pressure in the cylinder at one or more predetermined crank angles is used to estimate the fraction of fuel burned which, in turn, enables a determination of combustion failure in said cylinder cycle. Confirmation of said misfire or unacceptable partial burn leads to correction of engine operation by said controller and/or to a diagnosis of possible damage to the vehicle's catalytic converter. This method also permits better engine operation under conditions of high spark retard.

摘要： A method of controlling a direct fuel injection engine is provided. In the method, under a condition where an ignition timing which is accurately detectable is constant, a fuel injection timing is advanced and delayed to measure an average ion current, and the fuel injection timing is controlled so as to maximize the average ion current. Even when the efficiency of a solenoid is lowered to cause a variation of the fuel injection timing, the fuel injection timing can be controlled to be optimized, thus making it possible to maintain an intended efficiency of the direct fuel injection engine over a long period of usage. Particularly, the method can be realized by the use of a conventional ion current detecting device for detection of a misfire, it can be executed with an apparatus which can be attained at low cost. A direct fuel injection engine control system and a storage medium storing the control method of this invention are also provided.

摘要： A vehicle data acquisition and analysis system which acquires digital and analog input signals and analyzes information relating to vehicle component operation characteristics. A digital acquisition card is connected to at least one vehicle component to acquire a digital input signal data, and an analog acquisition card is connected to at least one vehicle component to acquire an analog input signal data. A connector (e.g., a bus) that provides a connection between the digital and analog cards synchronizes the digital and analog data acquisition when the acquisition of one card triggers the acquisition of the other card. The synchronized data is further processed upon the user's request to display the related vehicle characteristics.
