Abstract

In the dual fuel engine, much of the energy release comes from the combustion of the gaseous fuel and only a small amount of diesel liquid fuel provides ignition through timed cylinder injection. Such operation with optimum conversion methods has the potential to provide operational characteristics that are comparable or superior to those of the corresponding diesel or spark ignition engines. These characteristics may be realized only if sufficiently effective measures can be ensured both for the avoidance of knock, usually at high loads, and incomplete gaseous fuel utilization at relatively light loads. To overcome these problems associated with the operation of dual fuel engines over a wide range of fuels and their mixtures, better control of the relatively complex processes of combustion is essential. Both experimental and analytical modeling procedures for effecting optimum improvements to the combustion process are described.
