Active modular internal combustion engine system concept analysis

Today’s gasoline engines are using the group of new technologies to fulfill emission legislation and at the same time improve fuel consumption with excellent drivability performance and increase specific power and torque output. One technology group is focusing on the improvement of efficiency at low loads which includes Variable Charge Motion, Variable Valve Actuation, GDI Stratified and Homogenous Injection and the other group is shifting engine operating point towards more efficient operating areas by using Super/Turbo-Charging, downsizing the engine volume and choosing a longer gear ratio (down-speeding). This paper will show the engine concept with fully variable load and compression pressure control on extremely downsized engine as a part of unsynchronized boosting and turbine recuperation system. The concept in its nature offers constant torque over the full range, high transient response, no pumping losses which increases low load efficiency and highly efficient in-cylinder cycle.
