Description
This thesis is concerned with the experimental testing of a diesel dual fuel engine at low load and the development of a model to represent combustion in a dual fuel engine.<br><br>The experimental work involved the testing of various parameters such as injection timing and pressure, micropilot injection and boost pressure to determine their effect on the combustion, performance and emissions of a diesel dual fuel engine.
The effect of each of these strategies has been evaluated and in cylinder pressure measurements were also taken to allow the validation of the model produced during this project.<br><br>The theoretical side of this project involved the development of a turbulent flame model to be used with dual fuel engines. The model is based on the laws of thermodynamics and previous work found in the literature. The model has been made into a computer simulation program which predicts compression, combustion and expansion in a dual fuel engine.

The model has been compared to the experimental data and all results both experimental and theoretical have been discussed.<br><br>From the work undertaken it was discovered that by optimising the injection timings and quantities substitution rates can be achieved of up to 99%. It was also shown that the interaction between injection parameters can have a substantial effect on engine out emissions, with reductions in NOx between diesel and dual fuel operation and reductions in THC between dual fuel and micropilot operation.<br><br>There are also recommendations for future work to further improve the model and dual fuel engine performance and emissions.
