The AFR in a diesel at idle can be as high as is needed to create just enough energy to keep the engine idling. As a larger quantity of diesel is injected, the engine will speed up and create more energy. But it always combusts in the same way: the liquid diesel ...

Blending these fuels with gasoline or diesel can help to reduce our dependence on fossil fuels and promote the use of renewable energy sources. The conventional approaches for estimating the densities and viscosities of novel blended oxygenated fuels are either inaccurate or overly complex. With the ...
DieselIn this paper, we present a density-method-based model to allocate the refining cost to petroleum products such as gasoline and diesel. By using this model, we also present an empirical study of China, which is based on a virtual crude oil refining process proposed referring to the ...
The Energy Department’s EIA measures consumption of gasoline in terms of barrels supplied to the market by refiners, blenders, etc., and not by retail sales at gas stations. The volume of gasoline supplied has fallen for the third week in a row. This is unusu...
air. This air is very dense and very hot, so it is passed through a charge-air cooler, where it cools and gains even higher density before entering the engine. The presence of this compressed air makes the fuel burn more efficiently, delivering greater power while consuming less energy. ...

Diesel fuel and gasoline fuel produced from crude oil are commonly used fossil energy sources used in internal combustion in compression ignition or diesel engines and in spark-ignition engines, respectively. Crude oil contains many different hydrocarbons. Crude oil is physically separated into various ...
Wide distillation fuel is an option to improve compression ignition engine by blending diesel with gasoline at different octane number. The blend resulted in low soot emission, improved thermal efficiency and little sensitivity to gasoline octane number [16]. The effects of high RON on low ...
