This investigation is an effort to find best optimization method for diesel engine using blended fuel. Present time, the scarcity of fossil fuel is a serious problem all over the world. So, researchers are trying to find best alternative fuel for that conventional fuel. When we use alternate fuel in diesel engine, we must have to optimize the parameter of diesel engine. The present trend will b...

Automotive Systems A u to m o tive Sstem s Th e fuel pressure control system (FPCS) was developed to comply with increasingly strict fuel-effi ciency and emissions regulations by improving fuel economy and reducing emissions. It controls the discharge fl ow rate of the fuel pump and fuel injection pressure in accordance with engine operating conditions. Past fuel supply systems have operated th...

air pollution is one of the major issues about the diesel engines in todays' world. it is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilo...

The emission of solid carbonaceous particulate matter (i.e. soot) is a world-wide problem that effects both human health and global environmental health alike. Although a number of sources contribute to the concentration of soot in the atmosphere, Diesel engines play a significant role. Diesel engines, or direct-injection compression-ignition engines, are the primary power plant for delivering ...

The environment has recently led to very severe regulations on fuel consumption and exhaust emissions. I propose a scheme to minimize rate of fuel consumption for a direct fuel injection engine used by combination with a continuously variable transmission. Target values for the engine and the transmission which minimizes fuel consumption ensuring driving performance is calculated based on the n...

The purpose of present paper is simulation a direct injection stratified charge natural gas engine. The KIVA-3V code was used for gaseous fuel injection simulation. Compression and expansion stroke of engine cycle is simulated using KIVA-3V code. In cylinder fuel equivalence ratio distribution criterion is used for studying mesh independency. The results show that 550000 cells number is suff...

diesel engine emission standards are being more stringent as it gains more publicity in industry and transportation. hence, designers have to suggest new controlling strategies which result in small amounts of emissions and a reasonable fuel economy. to achieve such a target, multi-objective optimization methodology is a good approach inasmuch as several types of objective are minimized or maxi...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...
