Understanding Fuel Economy — “Gas” Mileage
Thermal efficiency, compression ratio, and fuel density are the primary factors that determine the fuel efficiency — a.k.a. fuel economy — of an engine. If mounted in a car, pick up, truck, boat, ship, a piece of heavy equipment, etc., even more, variables come into play with respect to the fuel
Gasoline Versus Diesel Engines: A Fuel Efficiency Comparison
Gasoline vs diesel engines — with respect to fuel efficiency — is not even a debate. Unlike in Europe and the vast majority of the rest of the developed world, it is not uncommon for people in the United States to be unaware that diesel is a better fuel than gasoline with respect to fuel [&helli
Latest Advances in Diesel Technology And What is To Come
Diesel, in relation to other fossil fuels, is an exceptionally dense fuel. There are a variety of properties that are inherent in dense fuels. Because of the inherent properties of diesel, diesel engines are extremely energy efficient both respect to combustion efficiency and thermal efficiency. H
Why Catalytic Converters are Necessary and Differ from Fuel Catalysts
Why Catalytic converters are necessary is because fossil fuels — particularly gasoline — do not combust efficiently without combustion-enhancing technologies. For some fossil fuels, their inherent chemical composition limits combustion efficiency potential, again, particularly gasoline. While
Compression Ratio: Why Diesel Engines are More Efficient than Gasoline Engines
Compression ratio plays as large a role in fuel efficiency as any other engine combustion factor. Diesel engines are between 25 percent and 35 percent more fuel efficient than gasoline engines of comparable size. If two vehicles have engines that are equal in size, but one has a diesel engine and th
What Determines Engine Fuel Efficiency: “Gas” Mileage of a Vehicle
Fuel efficiency is the product of two variables. Fuel density is one of two factors that determine fuel economy and thermal efficiency is the other. That is to say, fuel density and thermal efficiency determine the “gas” mileage of diesel, gasoline, biofuel, ethanol, and propane-powered vehicles
Why Diesel Engines are More Fuel Efficient than Gasoline Engines
Diesel engines are more fuel efficient than gasoline engines. That is to say, diesel engines get better “gas” mileage than comparably sized gasoline powered engines. There are two reasons why. First, diesel is a better fossil fuel than gasoline with respect to energy density. And second, diesel
