Abstract
The scavenging efficiency in a two-stroke uniflow scavenged engine is strongly affected by the velocity orientation of the gas entering the engine cylinder through the inlet ports. The report presents the effect of the inlet velocity orientation on the scavenging efficiency for the General Motors GM6V53T six cylinder, two-stroke, uniflow scavenged, direct injection turbocharged diesel engine. The only way the scavenging process can be studied accurately is by using multi-dimensional modeling because the process is geometry dependant. A two-dimensional model with swirl is used with the turbulence effects simulated using the K-e model. The momentum, continuity, energy, concentration, turbulence kinetic energy and energy dissipation rate conservation equations are written in finite difference form and solved explicitly in time.
