Combustion in Engines: Technology, Applications and the Environment - International Conference(1992-10 Proceedings of the Institution of Mechanical Engineers)

The need to reduce exhaust emissions for car engines is well known. The design of combustion engines with special emphasis on emission reduction while saving fuel and enhancing performance is a great challenge for engineers. Advanced computational techniques supported by experimental techniques have speeded up design precesses considerably. A major international conference "Combustion in Engines", organized by the Institution of Mechanical Engineers and held in London in December 1992 examined the latest developments in engine technology. Sessions covered computer modelling, diesel engines, spark igntion and combustion analysis. Some of the papers given were: development of a high fuel economy and high performance four-valve lean burn engine, warm-up characteristics of a catalyst heated by exhaust gas ignition and port throttles applied to a high performance four-valve SI engine. This volume contains the papers presented at the conference.
