Optimization of four stroke spark ignition engine for firesport

The effort of engineers is to achieve the highest possible power from the engine of a given size, in other words, to improve the weight - power ratio. This must be achieved while maintaining other parameters such as service life, emissions, fuel consumption, and others. Engine power is (simply put) given by the amount of air supplied to the combustion process. From this point of view, there are two ways to increase engine power: engine overcharging or improving the hydraulic conditions of the intake and exhaust system. This paper describes the second way - modifications of the four-stroke spark-ignition engine, which lead to engine power increase. Outputs using laboratory measurements have been verified. In addition, an engine model in Lotus Engine Simulation software has been created. The paper deals with the effect of some engine adjustments on the power: modification of valve shapes, modification of intake and exhaust ports, and camshaft modification. The described engine is mainly used in firesport, which is one of the most popular sport disciplines in the Czech Republic and in Slovakia. All adjustments are designed so that the modified engine meets the rules for firesport. Due to the fact that the assessed engine for sports industry has been used, neither fuel consumption nor emissions have been monitored.
