The developed 3-cylinder engine concept is compared to a benchmark 4-cylinder engine provided by VCC with respect to steady state performance and fuel consumption as well as transient response (Time-To-Torque). The 3-cylinder engine model is developed, tested and evaluated with GT-Power but it has not been fully validated with test-rig data.
