Characterization of Glow Plug and HCCI Combustion Processes in a Small Volume at High Engine Speed - Load Range, Emission Characteristics and Optical Diagnostics

Manente, Vittorio LU (2007)
Abstract
The objective of this research that has taken me halfway to my PhD degree was

to understand how HCCI combustion behaves in a small volume at high

rotational speed. The investigation has been carried out using a modified model

airplane engine. The whole study can be divided into two main parts; in the first,

the nature of the glow plug combustion was investigated through experiments on

a metal engine and by use of optical diagnostics. Once the glow plug combustion

process was fully understood, the engine was modified in order to achieve pure

HCCI operations. Initially, a basic investigation was carried out using a metal and

optical engine. Later, further research was... (More)

process was fully understood, the engine was modified in order to achieve pure

HCCI operations. Initially, a basic investigation was carried out using a metal and

optical engine. Later, further research was performed on the main parameters

affecting HCCI operations in such a small volume, i.e. the quenching distance,

wall temperature and combustion chamber geometry.

In addition to these studies, a model for calculating the amount of retained gas in

a 2-stroke engine was developed and a miniature HCCI free piston engine was

designed from scratch. (Less)
