Abstract
This study applies Closed-Loop Combustion Control

(CLCC) using Variable Compression Ratio (VCR) and

cylinder balancing using variable lambda to solve the

problem. Step changes of set points for combustion

phasing, Compression Ratio (CR), and load together

with ramps of engine speed and inlet air temperature

are investigated. Performances of the controllers are

investigated by running the engine at either a constant

amount of injected fuel corresponding to an

approximate load of 1.5 or 2.5 bar BMEP and/or

constant speed of 2000 rpm. Commercial RON 92

gasoline is used in the test. The CLCC is found to be

fast and effective and has a... (More)

fast and effective and has a potential of handling step

changes in a matter of cycles, while the speed and

temperature ramps need some more optimization of

the CLCC. The CR controller is very fast and has a

time constant corresponding to three engine cycles at

2000 rpm. (Less)
