INTERNAL COMBUSTION ENGINE WITH SUPERCHARGER

摘要

PROBLEM TO BE SOLVED: To provide an internal combustion engine with a supercharger increasing generated torque, having a high degree of freedom of design and inhibiting generation of knocking by accelerating atomization of fuel spray.

SOLUTION: The internal combustion engine 10 with the supercharger rotates a turbine 16 with exhaust gas discharged from an exhaust pipe 14 for supercharging of intake air sucked into an engine main body 30 from an intake pipe 12 through an air cleaner 18 and a throttle valve 20. Each cylinder 32 of the engine main body 30 is provided with two intake valves 34 and two exhaust valves 36. Two intake port portions 42 branched from an intake manifold 40 are connected to each cylinder 32. The two intake port portions 42 of each cylinder 32 are provided with one fuel injection valve 60 each. A total injection amount of the two fuel injection valves 60 provided on each cylinder 32 fulfills 400 cc/min or more.
