Knock damage in spark-ignition engines
… the damage caused by knocking combustion in spark-ignition engines. A literature review indicated that, in general, research into knock has focused on the causes and avoidance of knock, rather than on the damage resulting from knock. The few published works concerning the effects of knock …

The octane requirement of spark ignition engines
The thesis covers the fundamentals of refining and fuel technology, engine technology as regards parameters which influence knock and the results of engine tests. Definitions of octane number and the interpretation of the system developed to establish these numbers using the CFR engine are given. …

Particulate matter formation in spark-ignition engines
… of the mechanisms by which PM is formed in spark ignition (SI) internal combustion engines. A study was undertaken in order to understand the effects of dilution on measured PM, to examine and model the effect of steady state engine operating conditions on engine-out PM, and to characterize …

Modeling of combustion in spray-guided spark-ignition engines
… combustion process in modern spray-guided spark-ignition engines. Particular emphasis is placed on the ignition process, which requires the reproduction of the complex interactions of fuel injection, ignition, and early flame front propagation. In spray-guided spark-ignition engines, the …

Simulation of turbulent flames relevant to spark-ignition engines
… especially for internal combustion (IC) engines. Therefore, models used to predict such combustion have to be reliable, accurate and robust. In this work, the flamelet approach in the Reynolds-Averaged Navier- Stokes framework, is used to simulate flames relevant to spark-ignition IC …

Liquid fuel transport into the cylinder in spark ignition engines
… hydrocarbon (HC) emissions from automotive spark ignition engines particularly during the start-up and subsequent warm up period. As fuel does not readily vaporize under cold engine conditions, significant quantities enter the cylinder in liquid form, where they would be stored in various …

The potential of dissociated methanol as a fuel for spark ignition engines
This thesis examines the potential of dissociated methanol to increase the thermal efficiency or reduce the exhaust emissions of an internal combustion engine. It is assumed that liquid methanol will be dissociated onboard a vehicle using engine waste heat to produce a gas consisting of hydrogen …

The effect of inlet swirl on knock limits in spark ignition engines
… the effect of swirl ratio on knock limits in spark ignition engines. Initially it was attempted to find a correlation between swirl ratio and Knock Limited Spark Advance (KLSA) for a selection of commercially available engines. A comparison of measured swirl ratios and KLSA indicated that no …
