*Two-Stroke Super/turbocharging
Original language description
*Scavenging of two stroke engine requires the positive pressure difference between inlet and exhaust systems. The excess of scavenging air ? the greater, the poorer scavenging efficiency is ? dilutes burnt gas, decreasing its temperature. The inlet-exhaust pressure difference has to insure the necessary flow-rate during scavenging, depending significantly on available flow area of engine valves during scavenging period. The fast assessment of the system may be done using algebraic model of steady flow through engine with overlapped valve opening, turbocharger turbine-compressor power balance and exhaust gas temperature calculated from energy balance of a reciprocating two-stroke engine. All parameters describing gas exchange quality have to be estimated from experience or found by more deep 1-D or 3-D simulations combined with specific scavenging experiments.
