This document summarizes the computational analysis of a single cylinder, air cooled diesel engine using diesel-RK software. The analysis provided the engine's specifications, geometric properties, and results including 1.43 kW of power at 1500 rpm, 9.1146 Nm of torque, and 85.52% mechanical efficiency. Charts of heat release rate, NOx and soot concentration were also generated for the standard diesel fuel and an alternate 90% CH4 + 10% H2 fuel.
