摘要

A correlation based ignition delay calculation and knock integral model was investigated with experimental data using a multi-cylinder turbocharged direct-injection diesel engine at simulated altitude conditions. The study was conducted using three different cetane number fuels and altitude condition from sea level to 7,620 m (25,000 feet). A new method of determining start of combustion (SOC) with a dynamic threshold value was developed and verified for a range of operating conditions with high accuracy. Number of correlations found in literatures were tested for an Arrhenius equation with knock integral model to predict start of combustion and ignition delay at various operating conditions. The impact of manifold charge air temperature, fuel cetane number, and altitude were investigated. The predicted start of combustion was reasonably well matched to experimental results.
