The Electronic Return-less Fuel System (ERFS) manages the delivery of fuel from the fuel tank to the engine. The pressure in the fuel line is electronically controlled by the fuel system control module by speeding up or slowing down the fuel pump. This allows the system to efficiently control the amount of fuel provided to the engine when compared to vehicles equipped with a standard fuel syste...

A significant proportion of worker fatalities within Australia result from truck-related incidents. Truck drivers face a number of health and safety concerns. Safety culture, viewed here as the beliefs, attitudes and values shared by an organisation's workers, which interact with their surrounding context to influence behaviour, may provide a valuable lens for exploring safety-related behaviour...

Aerodynamic drag is the cause for more than two-thirds of the fuel consumption of large trucks at highway speeds. Due to functionality considerations, the aerodynamic efficiency of the aft regions of large trucks was traditionally sacrificed. This leads to massively separated flow at the lee side of truck trailers, with an associated drag penalty: roughly a third of the total aerodynamic drag. ...

Carbon deposition considered in a solid oxide fuel cell (SOFC) model may be influenced by the operating voltage, inlet water/methane ratio, working temperature and pressure, inlet molar fraction of fuel and so on. The effects of these parameters in a planar SOFC implementing a novel bi-layer interconnector are not well understood. This paper is focused on the numerical study of carbon depositio...

As occupant protection offered by new passenger vehicles has improved, there has been growing concern about the harm that some vehicle designs may inflict on occupants of other vehicles with which they collide. Preceding analyses of crash statistics have clearly demonstrated the incompatibility between passenger sedan cars (PS) and pick-up trucks (PU) involved in side impact crashes in British ...

Consequences of non-linearities in sfc, i.e. specific fuel consumption, of a heavy truck combustion engine are studied. A quasi-static analysis gives valuable insights into the intrinsic properties of the studied problem, i.e. minimization of fuel consumption on small gradients. Two objective functions are shown to give different optimal velocity trajectories on a constant gradient due to non-l...

The availability of retail stations can be a significant barrier to the adoption of alternative fuel light-duty vehicles in household markets. This is especially the case during early market growth when retail stations are likely to be sparse and when vehicles are dedicated in the sense that they can only be fuelled with a new alternative fuel. For some bi-fuel vehicles, which can also fuel wit...

This paper shows the modeling and simulation of fuel economy and vehicle dynamics of a heavy truck with Modelica. The work was carried out on MWorks, which is developed by Huazhong University of Science & Technology. Comparisons between measured data and simulation results validate the correctness of the model, and demonstrate that Modelica can be used in the modeling and simulation of vehicle ...

The increase in global competition and energy prices over the past decade has forced industries to search for potential savings in their transportation supply chains and logistics systems. In some industries, such as the forest products industry, minimizing the transportation costs of raw materials is even more crucial. The relatively low value and high weight of their raw materials accounts fo...
