COMPRESSION IGNITION INITIATION DEVICE AND INTERNAL COMBUSTION ENGINE USING SAME

摘要

An internal combustion engine (10) having a compression ignition initiation device (20) is provided. The compression ignition initiation device (20) includes a body (21) defining a chamber (34) and an outlet (36) from the chamber (34). The device (20) further includes means, within the chamber (34), for generating a combustion initiating shock front from the outlet (36). A method is provided, including compressing a mixture of fuel and air in an internal combustion engine cylinder (18) to a point less than a compression ignition threshold, and initiating ignition of the mixture by subjecting it to a shock front.
