- Abstract
- In order to meet the stricter and stricter emission regulations,
cleaner combustion concepts for Diesel engines are being
progressively introduced. These new combustion approaches
often requires closed loop control systems with real time
information about combustion quality. The most important
parameter for the evaluation of combustion quality in internal
combustion engines is the in-cylinder pressure, but its direct
measurement is very expensive and involves an intrusive
approach to the cylinder. Previous researches demonstrated
the direct relationship existing between in-cylinder pressure
and engine block vibration signal and several authors tried to
reconstruct the pressure cycle on the basis of information
coming from accelerometers mounted on engine block.
This paper proposes a method, based on the analysis of the
engine vibration signal, for the diagnosis of combustion
process in a Diesel engine. To this aim, the vibration signal
was firstly pass-band filtered and then, using this signal,
some global variables which characterize the combustion
quality were estimated. Finally, a possible control system
using the estimated combustion indicators was described.
All the experimental tests were carried out on a four-cylinder
Diesel engine running with operating conditions which
ensured low temperature and premixed combustions. (literal)
