ENGINE IGNITION AND COMBUSTION PROMOTION TECHNIQUE

摘要

Provided is an engine 100 equipped with: an intake port 20; a plasma generation part 31 which is provided on an inner wall 11a of a cylinder head part 11, generates non-thermal plasma in a combustion chamber 12, and is capable of reforming an air-fuel mixture introduced from the intake port 20 or an air-fuel mixture formed by using a fuel injection valve to inject fuel into air introduced from the intake port 20, the plasma generation part 31 comprising a first electrode exposed in the combustion chamber 12, comprising a second electrode facing the first electrode and covered with a dielectric material, and being embedded in the inner wall 11a of the cylinder head part 11; and an ignition part which is provided on the inner wall 11a of the cylinder head part 11 and ignites an air-fuel mixture reformed by electric discharge. An engine ignition method is also disclosed.
