APPARATUS AND METHOD FOR CONTROLLING COLD STARTING OF DIESEL ENGINE VEHICLE

摘要

A method for controlling a cold starting of a diesel engine vehicle may include determining whether a cold starting condition is satisfied by detecting data for controlling a diesel engine, determining torque generated by combustion for starting the diesel engine when the cold starting condition is satisfied, determining a combustion delay and a combustion phase based on the torque and detected data, determining a main injection timing according to the determined combustion delay and combustion phase, determining a latent heat of fuel based on the torque and detected data, determining a pilot injection amount according to the determined latent heat of fuel, determining a total amount of heat by combustion based on the torque and detected data, determining a main injection amount according to the determined total amount of heat, and controlling an operation of an injector based on the main injection timing, pilot injection amount and main injection amount.
