DYNAMIC CYLINDER DEACTIVATION FOR A SPARK IGNITION ENGINE
Original language description
Significant efficiency loss of the spark ignition engines with stoichiometric mixture stems from the throttling that occurs at the partial load of the engine, which is the most utilized mode during the engine operation. Downsizing and downspeeding have enabled to partially decrease this loss, however, with the upcoming trend of "rightsizing", de-throttling methods are again of higher interest. One of the approaches is cylinder deactivation, which has been used in static mode yet, i. e., usually half of the even number of cylinders is switched-off during part load operation (and lower engine speed). Another approach in the cylinder deactivation is its dynamic use, i. e., all cylinders continuously switch between the activated and deactivated mode. This is suitable particularly for odd number of cylinders and does not exist in production yet. The paper deals with 1-D simulation of this kind of cylinder deactivation, compares different approaches to the gas exchange process of such deactivation, points out the benefits and advantages over other partial load control methods and also shows simulation issues that emerge with the dynamic deactivation.
