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
Lower Diesel Emissions: Reducing Diesel Engine Emissions with Technologies
Lower diesel emissions mean better health for both people and the environment. To be fair, however, it should be noted that diesel engines exceptionally fuel efficient in relation to gasoline, ethanol, biodiesel, and propane-powered engines. A diesel engine is between 25 percent and 35 percent mor
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
