CONSTITUTION:A control unit 30 controls an igniter 27 according to an optimum ignition timing determined on the basis of an engine operative state, and further, feedback-controls the opening of an ISC valve 14 at judgment of an idling operation. There is provided a mode judging unit 31 for ...
Method for split ignition timing for idle speed control of an engine A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, such as after an engine cold start, the method operates an engine with a first group of cyli...

In addition, the ignition delay is affected by various parameters such as fuel characteristics, combustion quality, engine speed [107], and injection timing [108]. For HCCI and LTC combustion, the ignition delay is one of the key factors affecting the successful development of the engine. ...
A method and an apparatus for setting the timing of the ignition system (CDI) of an internal combustion engine (M); after checking the timing of the ignition circuit (CDI) with the engine (M) running at a predetermined speed, and determi... V Alessandro,G Christian 被引量: 0发表: 1996...
The highest engine efficiency was achieved with the same natural gas DI system. The highest iSHC, iSCO, iSCO2 and iSNOx emissions reduction achieved at low and part load conditions with DI-CNG compared to GDI combustion. Particulates formation was lower with the gaseous fuel compared to gasoline...
The valve train and engine management system must provide a fast and smooth transition between these two very different combustion modes keeping all relevant engine and combustion parameters in an acceptable range. To accommodate such transition a valve event (comprising duration, timing and lift) has...

The liquid WI mass into the cylinder depended on the intake air mass, the temperature of compressed air, the water temperature, and the engine speed, among other parameters. The injection of excessive amounts of liquid water into the cylinder could result in poor evaporation and could have an...
Modern engines employ knock sensors to detect when knock is occurring and then adjust the spark timing of the engine to lower the pressures and temperatures, thus avoiding knock, albeit at a lower engine performance. This paper aims to comprehensively examine the different signals that are ...
