LPG has been well known as a clean alternative fuel for vehicles. Recently, several LPG engines for heavy-duty vehicles have been developed, which can replace some diesel engines that are one of the main sources for air pollution in the urban area. Because cylinder bore size of heavy-duty LPG engine is larger than that of gasoline. the study of knock characteristics is essential for developing LPG engines.
In this study, three-dimensional transient simulation was performed and a knock model was implemented to predict knock occurrence and autoignition site in a heavy-duty LPG engine. A FAE premixed combustion model and a flame wall-quenching model were applied to simulate flame propagation. A reduced kinetic model was adjusted to LPG fuel and used to simulate autoignition in the unburned gas region
Engine experiments using a single-cylinder research engine are performed to calibrate the reduced kinetic model and to verify the results of this modeling. A pressure transducer and head-gasket type ion-probe circuit board are installed in to detect knock occurrences, flame arrival angles, and autoignition sites.
The simulation result shows good agreements with the cylinder pressures, flame arrival angles, knock occurrences, and autoignition sites of the engine experiments. It also provides much information about in-cylinder phenomena and some ways to reduce knocking tendency. This knock simulation can be used as a development tool of engine design.
