Method of starting a cylinder injection engine

A starting method of a cylinder injection engine which includes a combustion chamber introducing air, a fuel injection valve directly injecting a fuel into said combustion chamber, a piston varying volume of said combustion chamber, a starter for starting up the engine, an EGR piping connecting an exhaust pipe to an air intake pipe, and an EGR valve, said method comprising the steps of:

• actuating said starter in a cold start of said engine when an engine coolant temperature is lower than a predetermined value;
• opening said EGR valve while said starter is actuated for starting up said engine in said step of actuating the starter;
• and
• injecting a fuel provided in deflected spray form during a compression stroke in said step of actuating the starter.

A starting method of a cylinder injection engine which includes a combustion chamber introducing air, a fuel injection valve directly injecting a fuel into said combustion chamber, and a piston varying volume of said combustion chamber, a starter for starting up the engine and a variable valve mechanism for controlling opening and closing timing of an intake valve, said method comprising the steps of:

• actuating said starter in a cold start of said engine when an engine coolant temperature is lower than a predetermined value;
• controlling a valve closing timing of said intake valve at the maximum retard position while said starter is actuated for starting up said engine in said step of actuating the starter;
• and
• injecting a fuel provided in deflected spray form during a compression stroke in said step of actuating the starter.
