Abstract
The objective of this Master Thesis is to investigate the homogeneity level of the Partially
Premixed Combustion using different injection strategies, for low load engine conditions.
In order to achieve this aim, it is necessary to understand the Partially Premixed Combustion
process of an engine through the performance of optical measurements in an optical setup.
Partially Premixed Combustion (PPC) is a process that can provide a combustion with low
emissions and high efficiency. The term Partially Premixed Combustion is used to describe
an engine which is operating somewhere between fully homogeneous combustion HCCI and
diffusion controlled diesel combustion. Hence, the goal of this work is to increase the
knowledge base of PPC.

knowledge base of PPC.
This project will be performed in a light duty engine based on a Volvo D5. This engine has
been modified to be run in an optical setup, in order that the engine was converted into a
single cylinder with a Bowditch piston extension.
Optical diagnostic methods based on combustion chemiluminescence were carried out to
determinate the homogeneity level of the combustion. These events will be recorded by a
high speed camera, a device capable of capture processes in the combustion chamber.
The analysis of the combustion homogeneity is carried out through a frequency analysis which
allows to compare the different injection strategies that have been studied and analysed in this
master thesis. (Less)
