Method for accurate measurements of detonations in motorbike high speed racing engine

摘要

All high-efficiency engines are inclined to destruction tendencies in consequence of detonation combustion. Most often the producers of engines solve this problem with a limitation of a maximum output performance but therefore there is decreased an efficiency of fuel utilization. When the detonation caused by pre-ignition and postignition, it is generally known that strong vibrations from the combustion chamber develop from impact of that combustion pressure. This will affect the engine. Methods to accurately measure the strength of this detonation and its usage are being considered and used from various viewpoints. We measure this detonation quantitatively by the detonation counter. This is done in order to bring out optimum performance of the engine, specifically the spots, carburetor settings, and ignition timing. Where adjustments must be made and it is useful as a tool for judging, conducting, and setting adjustment directions and volume quickly and accurately.
