The launch of the new 1.8 l TFSI engine marks the third generation of the successful four-cylinder gasoline engine family from Audi. It has been completely revised in order to meet ambitious CO2 targets and ensure compliance with future Euro 6 emissions standards. The new generation features numerous innovative technologies, including an exhaust gas cooling system integrated into the cylinder h...

This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performa...

Driven by the Paris agreement and tightening IMO regulations, marine sector is focusing on lowering engine emissions moving to low-carbon fossil or renewable fuel such as methane. The dual-fuel concept allows usage of methane main energy-source in diesel engines. A small pilot injection acts an ignition source for premixed It was investigated how NOx formation, mainly taking place during combus...

Hybrid excavator control strategy based on rules optimizes the specific fuel consumption only to determine engine operating point in the perspective of qualitative analysis, it is not sufficient to reduce the excavator fuel consumption because of ignoring the affect of engine power output. In this paper, an instantaneous minimum fuel consumption control strategy for hybrid power-train is propos...

A comprehensive study on the methanol as an alternative fuel has been carried out. A four stroke four cylinder diesel engine was adopted to study engine power, torque, break specific fuel consumption, break thermal efficiency and exhaust temperature with the fuel of fraction methanol in diesel. In this study, the diesel engine was tested using methanol blended with diesel at certain mixing rati...

The dual clutch transmission was introduced in vehicles to improve driving comfort compared with manual transmissions, and performances, fuel efficiency compared with automatic transmissions. The dual clutch transmission allows to shift gears quickly, comfortably and without interruption in traction. In the dual clutch transmission, the management of the dual clutch in the gearshift phase is a ...

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...
