dc.description.abstract |
Diesel engines are the most commonly used internal combustion engines nowadays, especially in European transportation. This
preference is due to their low consumption and acceptable driveability and comfort. However, the main disadvantages of traditional
direct injection Diesel engines are their high levels of noise, nitrogen oxides (NO x) and soot emissions, and the usage of fossil fuels.
In order to tackle the problem of high emission levels, new combustion concepts have been recently developed. A good example
is the premixed charge compression ignition (PCCI) combustion, a strategy in which early injections are used, causing a burning
process in which more fuel is burned in premixed conditions, which affects combustion noise. The use of a pilot injection has
become an effective tool for reducing combustion noise. The main objective of this paper is to analyze experimentally the pollutant
emissions, combustion noise, and performance of a Diesel engine operating under PCCI combustion with the use of a pilot injection.
In addition, a novel methodology, based on the decomposition of the in-cylinder pressure signal, was used for combustion noise
analysis. The results show that while the PCCI combustion has potential to reduce significantly the NO x and soot emission levels,
compared to conventional Diesel combustion strategy, combustion noise continues to be a critical issue for the implementation of
this new combustion concept in passenger cars. |
