Optimized Driving Cycle Oriented Control of a Highly Turbocharged Gas Engine 2019-01-0193
The article is focused on a 1-D drive dynamic simulation of highly turbocharged gas engine. A mono fuel CNG engine has been developed as a downsized replacement of the diesel engine for a medium size van. The basic engine optimization is provided in a steady state operation and a control adjustment is applied to a dynamic vehicle model for a transient response improvement in dynamic operation modes of the WLTC (world light duty test cycle), that has been selected for investigations. Vehicle simulation model with optimized control system is used for a cycle fuel consumption and CO2 emissions predictions and compared with the basic engine settings.
