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

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.

► We measured detonations in a high-speed engine of racing motorbike.
► Application of these detonations was considered with regard to various viewpoints.
► The exact quantitative measuring of the detonations was performed by means of a detonation counter.
► This process was done in order to bring out optimum power output of the engine, especially the spots, carburetor settings and ignition timing.
