Analysis of HC Emissions on Single Cylinder During Transient Conditions 2004-01-0981

For studying simultaneously and early in the development process the effects of engine design parameters and of control strategies on HC emissions, a methodology has been set up to reproduce on a gasoline single-cylinder engine the beginning of MVEG cycle. This methodology uses different fuels and analysis tools to assess the HC sources. Oil and water are heated to follow the thermal behavior of a multi cylinder engine. A fast prototyping system is used to control the engine. Special attention has been paid to take into account the acoustic effect on the air feeding.
The main tendencies observed in stabilized conditions are similar to transient test conditions with GDI engine. Wall wetting appears as the main source of HC emission in case of direct injection. Transient effects are especially sensitive during cold conditions.
