BACKGROUND We examined whether sales of new motorcycles was a mechanism to explain the relationship between motorcycle fatalities and gasoline prices. METHODS The data came from the Motorcycle Industry Council, Energy Information Administration and Fatality Analysis Reporting System for 1984-2009. Autoregressive integrated moving average (ARIMA) regressions estimated the effect of inflation-a...

In the present investigation, behavior of fuel consumption was studied due to high cost gasoline and its price increase in Ecuador recent years, for which reason different mixtures have been obtain lower consumption. The optimum mixture rate a T18SED e-tec II engine, Multiport Electronic Fuel Injection System (MPFI) between extra gasoline, super ethanol obtained on two urban roads city Quito (E...

In this experimental study, the effect of alcohol (ethanol and methanol) use on the performance, emissions and combustion characteristics of a low power single-cylinder engine described the rated power output of the engine e.g. 2 kW were investigated and the results were compared with conventional gasoline operation. The tests were performed at full-throttle valve opening and variable engine sp...

Homogenous Charge Compression Ignition (HCCI) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. But in contrast to gasoline and diesel engines, HCCI engines suffer from lack of having direct means to initiate combustion. A combustion timing controller with robust tracking performance is the key requirement to leverage HCCI application in production ...

With modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. In this experiment tri fuel concept was used according to that diesel and turpentine different proportion bled introduced in diesel engine and acetylene entre in the diesel engine through intake manifold in the diesel engine. Among the many process parameters,...

The present study converses the usability of ethanol as a clean and green renewable alternative fuel for spark ignition engine. The study emphasizes not only on the inherent properties of ethanol as a fuel but also elaborately reviews about the performance characteristics of the engine considering the effects of different important parameters like cyclic variability, ignition timing, internal c...

In an effort to reduce dependence on petroleum-based fuels and increase engine efficiency, fuel-flexible engines with advanced technologies, including variable valve timing, are being developed. Fuel-flexible spark-ignition engines permit the increased use of ethanol–gasoline blends. Ethanol, an alternative to petroleum-based gasoline, is a renewable fuel, which has the added advantage of impro...
