Hydrocarbon (HC) emissions from direct injection (DI) diesel engines are mainly due to fuel injected and mixed beyond lean combustion limit during ignition delay and fuel effusing from the nozzle sac at low pressure. The concept has been developed to provide an elegant model to predict the HC emissions considering slow burning. The model has been validated by collecting data on HC and pressures in cylinder and in fuel injection system from the experimental engines which are naturally aspirated, turbocharged or turbocharged with intercooling. New universal coefficients for the correlation of HC with operating parameters were obtained.
