Investigation of Cylinder Deactivation (CDA) Application on a Naturally Aspirated Engine

Increasing oil prices and emission legislation have forced automotive company to investigate new methods technologies reduce the harmful effect produced from motor vehicle, particularly CO2 (Carbon-Dioxide).A lot of studies research been put into in order achieve a zero vehicle with usage electricity rather than fossil fuel, but challenge cost environmental makes an IC engine is still being predominant power plant for automobile this century. One popular techniques among manufacturers better efficiency cylinder deactivation. Cylinder deactivation promising method fuel consumption by operate at higher load. However, combustion pressure extreme temperature firing cylinders will result NOx composition. This paper further performance, economy using one-dimensional (1-D) simulation tool. A standard 1.6 litre naturally aspirated four in-line cylinders, port injection modelled correlated measured test data. The model then simulated mode deactivating intake exhaust valves no 2 3 as well various speeds part load conditions show improvements consumption, emissions, pumping losses effects on CO emission. used application EGR level. Also, in-cylinder are presented. study shows that very significant CDA mechanism ensure overall emissions reduced simultaneously.
