Closed-Loop Control of an HCCI Engine

Olsson, Jan-Ola LU ; Tunestål, Per LU orcid and Johansson, Bengt LU (2001) SAE World Congress, 2001 In SAE Transactions, Journal of Engines 110(3). p.1076-1085
Abstract
This paper presents a strategy for closed-loop control of a multi-cylinder turbocharged Homogeneous Charge Compression Ignition (HCCI) engine. A dual fuel port injection system allows control of combustion timing and load individually for each cylinder. The two fuels used are isooctane and n-heptane, which provides a wide range of autoignition properties.



Cylinder pressure sensors provide feedback and information regarding combustion. The angle of 50% heat release is calculated in real time for each cycle and used for timing feedback.



Inlet air preheating is used at low loads to maintain a high combustion efficiency.
