Title:

INTERNAL COMBUSTION ENGINE OPERABLE IN PCCI MODE WITH EARLY CONTROL INJECTION AND METHOD OF OPERATION

Document Type and Number:

WIPO Patent Application WO2001086128

Kind Code:

A3

Abstract:

An internal combustion engine (10) operable in a premixed charge compression ignition mode and a method for operating the engine (10), the engine (10) including an engine body (12) with a piston assembly (14), a combustion chamber (16) formed in the engine body (12) by the piston assembly (14), an intake system (18) for delivering intake air to the combustion chamber (16) during an intake stroke, a mixing device that mixes a first fuel (23) with the intake air to provide a premixed charge of air and the first fuel (23), a direct fuel injector (26) adapted to directly inject a second fuel (27) into the combustion chamber (16), and a control system (20) adapted to control the direct fuel injector (26) in a manner to provide at least one early control injection, and preferably, a plurality of early control injections of the second fuel (27) into the combustion chamber (16) before start of combustion of the premixed charge.
