HCCI Combustion Phasing with Closed-Loop Combustion Control Using Variable Compression Ratio in a Multi-Cylinder Engine
(2003) In SAE Transactions, Journal of Engines 112(4). p.1233-1245- 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) - This study applies Closed-Loop Combustion Control

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)
