Exhaust gas emissions from motorized vehicles also contribute to air pollution in our environment. So it is necessary reduce so that the negative impacts on humans, animals and environment can be reduced. Hoping making alternative tools exhaust 100cc motorcycle vehicles. With experimental methods testing of motor vehicle with a comparison standard data. Tests are carried out determine results e...

A number of large studies have reported that environmental pollutants from fossil fuel combustion can cause deleterious effects to the immune system, resulting in an allergic reaction leading to respiratory tract damage. In this study, we investigated the effect of motorcycle exhaust particles (MEP), a major pollutant in the Taiwan urban area, on airway inflammation and airway hyperresponsivene...

In recent years, increasing concerns regarding the energy costs and environmental effects of urban motorcycle use have spurred the development of hydrogen-electric motorcycles in Taiwan. Although gasoline-powered motorcycles produce substantial amounts of exhaust and noise pollution, hydrogen-electric motorcycles are highly energy-efficient, relatively quiet, and produce zero emissions, feature...

Previous studies in the United States and internationally suggest that low motorcycle conspicuity, or the inability of the motorcyclist to be seen by other road users, is an important factor associated with the risk of motorcycle crashes. However, there has been limited research on motorcycle conspicuity in the United States in the past two decades, while at the same time, there has been a rene...

Different optical techniques were applied to describe the thermal and chemical processes that occur in a SI small engine from the ported fuel injection and in-cylinder mixture formation to the combustion process and the exhaust emission. In PFI SI engines, the atomized fuel is sprayed towards the intake valves, where it may evaporate, puddle or rebound. Furthermore, a portion of the fuel may fl...
