Optimization of the Performance of Two-Stroke Spark-Ignition Engines Using a Capacitor in the Exhaust Manifold 891807

The performance of a small cross-scavenged two stroke spark ingition engines have been analysed by means of a displacement-mixing model for the intake gases, a two-zones combustion model, and one-dimensional numerical technique for the gas flow in the exhaust system. Numerical studies have shown that two stroke engine performance can be optimized by using a resonant chamber connected by means of a valve to the exhaust manifold. The configuration of the exhaust system C the resonant chamber's volume, the geometry of the pipe) may be determined as function of the required engine applications by the implemented code.
