This paper describes the method used for heat transfer measurement and prediction on the LiquidPiston XMv3 small rotary engine at its current state of development. A 1D engine model (GT-POWER) and a 3D CFD model (CONVERGE), were coupled together with the objective of quantifying the engine heat transfer losses inside the combustion chamber.

This paper describes the initial development progress of small rotary internal combustion engines developed to operate on the High Efficiency Hybrid Cycle (HEHC). This innovative rotary engine architecture shows a potential indicated efficiency of 60% and brake efficiency of >50%. Two prototype ‘X’ rotary engines are discussed. The first engine is the larger X1 engine (70hp), which operates on the HEHC with compression-ignition (CI) of diesel fuel. A second engine, the XMv3, is a scaled down X engine (70cc / 3HP) which operates with spark-ignition (SI) of gasoline fuel.DOWNLOAD NOW
