The purpose of this research is to clarify that ignition characteristics such as ignition energy and discharge pattern have effect upon maximum pressure, maximum pressure appearance timing. IMEP and revolution of engine on the lean burn of mixture. In this paper, We studied relations between discharge performance of ignition energy and extension of lean inflammability by development of High Frequency Ignition System.

In the spark ignitio engine, the number of the electronic control parts is increased so that the harmful exhaust gas can be reduced and the thermal efficiency of the engine can be enhanced. ECU can control the function of the engine better when the function signals of the engine are converted into the electrical signal under optimum condition. This study deals with the improvement of the signal measuring and processing for the electronic control in the SI engine. The measurement algorithm was developed within 1°accuracy of the crank angle, and as a result, the function of the engine can be more precisely controlled, such as the duration of the fuel injection and the timing of the spark ignition.

In the spark ignition engine, the amount of the electronic control parts increase so that the harmful exhaust gas can be reduced and the thermal efficiency of the engine can be enhanced. ECU(Electronic Control Unit) can control better when sensors which are mounted on the engine are converted into the electrical signal and processed to the optimum condition for the engine control. This study aims at the development and the improvement of the signal measuring and the signal processing for the electronic control in the SI engine. We can get the algorithm of the measurement within 1° of the crank angle, and as a result we can control the function of the engine more precisely such the duration of the fuel injection and the timing of the spark ignition.<br/>

In a SI engine, it is necessary to control fuel quantity in accordance with intake air amount in order to reduce exhaust emission and improve the specific fuel consumption. Precise AFR control requires measurement of air amount with respect to the cylinder and injection fuel according to the air amount. In this paper, we applied nonlinear fuel injection model, and developed the algorithm of AFR control. This algorithm includes the methods of measurement of transient air mass flowing into each cylinder, of calculation of injection pulse width for measured air mass, and the method of feedback and estimation control by using lambda sensor. Also we developed control program for IBM-PC by using C++ Builder, and tested it in the commercial engine. The results we have got from the work better than those of the commercial ECU.<br/>

For a digital engine control system, control timings such as ignition and injection are based on the crank shaft angle. Therefor, it is very important that the angle of the crank shaft have to be detected with accuracy for the fuel injection and ignition timing, the sequential multi-point injection(MPI) system that has a independent injector in each cylinder, is used to inject the fuel of the accurate quantity, and to cope with varying of the engine status. The distributorless ignition(DLI) System that is the direct ignition method, is used for the accurate ignition and the flexible ignition timing. We install a sensor that occurs a number of events for the accurate detecting of the angle of the crank shaft.<br/> This study aims to make a event detecting algorithm, a method to detect the crank shaft angle by a event, and a software witch output a control signal at the given angle values.<br/>

It is a necessary condition to control the precise air-fuel ratio with real time for the stability of lean burn including transient operating condition as well as other factors as flow of mixture and ignition energy in SI engine.<br/> This study aims to development of software and hardware such as the engine control system and interface. Real time control system is introduced and its characteristics are tested in SI engine. The real time control system was applied to SI engine and the results are shown.<br/>
