279 - 2.0 110 kW Engine with Gasolina Direct Injection - Volkspage

Engine

Engine management Stratified charge operation is not possible over the entire map range. The range is restricted due to the fact that greater loads require a richer mixture and the fuel consumption advantage becomes progressively less. Combustion stability also deteriorates with Lambda values less than 1.4, as the mixture preparation time is no longer adequate with increasing engine speeds and the greater airflow turbulence has a negative effect. Homogeneous operation λ = 1 or λ > l with 3-way catalytic converter Homogeneous lean operation with λ = 1.5 Charge stratification with adapted in-cylinder flow and optimised EGR strategy Effective mean pressure (bar) Engine speed rpm 279_029 Maximum fuel economy is achieved in stratified charge operation. 22
