A Study on Knocking Analysis Simulator Based on CRDI Engine ECU
In order to meet the recently enhanced emission standards at home and abroad by applying CRDI (Common Rail Direct Injection) diesel engines to industrial engines, this study developed the CRDI ECU control algorithm that users can adjust fuel injection timing and amount. This study aimed to improve fuel economy and to reduce harmful gas emissions effectively by developing the algorithm distinguishing diesel knock and long tooth with the use of CKP and CMP sensors among the input factors of CRDI engine control ECU, and by adjusting engine balance through the development of algorithm that can determine when adjusting the fuel injection timing and amount, and distinguish abnormalities of engines.
Vehicle Diesel Engines
The diesel engine came to be used as a car engine relatively late after the first demonstration of its operation in 1897. The introduction of the first mass produced diesel passenger cars in 1936 finally enabled diesel engines to vie with the dominant gasoline engines of the day as an alternative drive concept in this segment too.
Diesel- und Erdgasmotoren fuer schwere Nutzfahrzeuge. Emissionen, Verbrauch und Wirkungsgrad
Sowohl bei den limitierten Schadstoffen, insbesondere bei Stickoxiden und Partikeln, wie auch bezuglich der Ozonbildung und Karzinogenitat ist Erdgas den konventionellen Treibstoffen uberlegen. Die CO2-Emissionen und der Wirkungsgrad treten bei den Antriebsquellen vermehrt in den Vordergrund. Der nachfolgende Beitrag der Empa (Schweizerisches Forschungsinstitut fur Materialwissenschaften und Technologie) stellt aktuelle und zu erwartende Tendenzen von Motoren fur schwere Nutzfahrzeuge und Busse dar.
