DUAL INJECTOR ENGINE HAVING HEATER METHOD FOR CONTROLLING ENGINE USING IT

摘要

PURPOSE: A method for controlling an engine using a double injector engine having a heater is provided to start an engine smoothly even only low- energy density of a bio fuel is used by spraying the bio fuel with heated inhale-air to a combustion chamber in a low-load condition of a vehicle. CONSTITUTION: A double injector engine comprises a first injector, a second injector, a heater and a pressure sensor. The first injector is installed in a cylinder head of an engine and sprays diesel oil to a combustion chamber. The second injector is installed in an intake pipe(13) of the cylinder head. The second injector sprays bio fuel to the intake pipe. The heater is installed in the intake pipe and heats intake air flowing into the intake pipe. The pressure sensor is installed in the cylinder head and senses the pressure of the combustion chamber.
