The main target for the development of power sport engines is and will be in future the increase of the power-to-weight ratio. However, the reduction of carbon dioxide emissions is getting more and mo....
Racing engines are required to be developed quickly in order to adapt to ever-changing regulations. A CFD-based optimization would be a useful tool to discover the best solution given the restrictions....
Based on the fuel consumption analysis methods published on last year's SETC [1], we compared fuel economies of a typical 125cc production motorcycle equipped with either electronic (port) fuel inject....
Within a project of a research association (Forschungsver-einigung Verbrennungskraftmaschinen e.V.) a DI spark-ignition engine with small engine displacement was designed at the Institute of Internal ....
Recently, producing energy with reduced CO₂ emissions has been one of the most important topics of global discussion. Combined heat and power (CHP) systems, which use natural gas to produce thermal en....
The research shows the experimental results for a free piston linear engine according to operation conditions of the linear engine and the structure of linear generator for generating electric power. ....
An existing 4 stroke-cycle gasoline engine has been partially modified without dynamically changing its mechanism for the purpose to utilize compressed air as an alternative energy source. The princip....
Small combustion engines can be found in various applications in daily use (e.g. as propulsion of boats, scooters, motorbikes, power-tools, mobile power units, etc.) and have predominated these market....
This paper is describes the proposal of continuous variable valve timing and lift mechanism by the electromagnetic valve applying the solenoid. This continuous valve timing and timing mechanism is ver....
Emission regulations in California typically require exhaust treatment with a 3-way catalyst to achieve emission standards for inboard boat engines. The relevant legislation of EPA (Environmental Prot....
Extensive research is being carried out to improve the volumetric efficiency of the engine by improving port flow. Port flow characteristics plays vital role in determining the overall performance of ....
Engine life and effectiveness can be improved with effective cooling. In designing and optimization process, simulation plays a vital role. The cooling mechanism of the air cooled engine is mostly dep....
