KOMPICS on a High BMEP Engine

Abstract

A current strong demand for conserving raw materials and fuel economy of diesel engines leads us inevitably to a high BMEP (break mean effective pressure) engine concept. Since the engine based on this concept explore more power within the limit of the same raw material package as well as within the same noise limit, the high BMEP approach seems better than the high engine speed approach to establish high output. However a high BMEP engine concept has not been used well so far except for some special application such as a military engine due to its disadvantages which is so far considered inherent. To resolve these disadvantages of a high BMEP engine, KOMPICS- an electronically controlled high injection pressure system was applied and the fact that the disadvantages of high BMEP engine such as smoke, low end torque, and transient response can be removed by KOMPICS has been found. This high BMEP engine was installed on a generator set and the performance and market seeding test has been done. The results are found acceptable and attractive. Thus it is concluded that a high BMEP engine is now at a stage of a wide application.
