Reducing vehicle fuel consumption has become one of the most important issues in recent years. Aerodynamic drag contributes to 50-60% of fuel consumption in trucks on highways. Vehicle aerodynamic performance is mainly determined by drag coefficient, which directly affects engine requirements and fuel consumption. It’s well known that drag changes in a crosswind compared with a condition without a crosswind, and that the change depends on the vehicle shape. Pressure drag, a major drag for...

The gap between certified and real-world passenger vehicle emissions is widening and has driven vehicle policy transitions in the US and in Europe, particularly in the wake of emissions measurement scandals. Since carbon dioxide emissions are highly correlated with fuel consumption (FC), fuel consumption regulation is a useful policy instrument to combat climate change. Although the Chinese government set fuel economy standards in 2004, like many countries it does not conduct testing to confirm...

This paper looks at fuel consumption due to shaft power off-takes from the engine and the related increase in the aircraft's fuel consumption. It presents a review and comparison of published and unpublished data on this kind of consumption. Insight is given into the effects caused by off-takes, looking at phenomena inside the engine when shaft power is extracted. The paper presents results from the TURBOMATCH engine simulation model, calibrated to real world engine data. Generic equations are...

The main Soviet biomedical experiments conducted since the beginning of space flight are reviewed; on the basic of their results, it is concluded that prolonged manned space flight is possible, although certain apparently reversible changes in vital processes have been noted. The experiments are divided into four groups: research on mammals and turtles, on insects and amphibians, on plants, and on microorganisms and tissue cultures. In these experiments, the genetic effect of cosmic ionizing...

The Compressed Natural Gas (CNG) is a vaporous type of regular gas, it has been proposed as one of the promising option fuel because of its considerable advantages contrasted with gas and diesel. Iraq is considered as the fundamental NG repositories on the planet. Albeit normal gas can meet strict motor discharge controls in numerous nations, it has not utilized as a fuel for transport motors. In this study, regular gas motor qualities were explored tentatively to assess the impact of motor...

For fully supersonic flows, an efficient strategy for obtaining numerical solutions is to employ space marching techniques. A full potential marching technique, known as the SIMP code and capable of handling such embedded subsonic regions, has achieved some success analyzing low supersonic Mach number flows. The extension of the full potential approach to the Euler equation which model the exact nonlinear inviscid gas dynamic flow processes is presented. Within the assumption of an inviscid...

Hybrid vehicles are common in the marketplace for passenger cars and commercial applications such as delivery trucks and transit busses. One of the biggest justifications for hybrids is their fuel efficiency. However, the U.S. military has yet to field a hybrid vehicle even though battle field fuel costs can be as much as $400 per gallon. This is not due to a lack of investment in research and development, since much work has been done. The goal of this survey paper is to summarize past...

The primary question posed in this study is whether premium or regular gasoline is more cost effective for the Montgomery County Public School (MCPS) bus fleet, as a whole, when miles-per-gallon, cost-per-gallon, and repair costs associated with mileage are considered. On average, both miles-per-gallon, and repair costs-per-mile favor premium gasoline by a slight margin. However, cost-per-mile significantly favors the use of regular gasoline with the net result that the total cost-per-mile is...

The development of a theoretical model is investigated of the incompressible jet injection process. The discharge of a turbulent jet into a cross flow was mathematically modeled by using an integral method which accounts for natural fluid mechanisms such as turbulence, entrainment, buoyancy, and heat transfer. The analytical results are supported by experimental data and demonstrate the usefulness of the theory for estimating the trajectory and flow properties of the jet for a variety of...

An online power management strategy (PMS) for plug-in hybrid electric vehicles is presented in this paper. This PMS with the capability to reduce both the fuel consumption and the emission, has simple mathematics and excludes a priori knowledge of the driving cycle. The only required information is the driving duration that can be estimated by the driver or by the vehicle information systems, so the proposed method can be easily implemented. Furthermore, an adaptive form of this PMS is...
