Abstract

An internal combustion engine includes a cylinder including at least one intake valve which is selectively open to allow at least air to enter the cylinder and at least one exhaust valve which is selectively open to allow residual gas escape from the cylinder after a firing event. An auto-ignition system for such an engine comprises a device communicably coupled with the cylinder. The device is, effective to allow an amount of high temperature and pressure residual gas to enter the cylinder in the compression stroke of an engine cycle after valve closure of the intake valve.
