Why Diesel Engines Get Better Gas Mileage and Burn Cleaner than Petrol Engines
Why diesel engines get better gas mileage and burn cleaner than petrol engines is because diesel is a cleaner more energy dense fuel. A diesel engine is between 25 and 35 percent more fuel efficient than a gasoline vehicle of comparable size. With a diesel engine, you go to the pump much less often
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
Diesel vs Biodiesel: Which is better for the Environment and Why?
Diesel versus biodiesel, which is better for the environment? The answer to the question seems to have an obvious answer. The names alone indicate which is better for the environment, right? The prefix “bio” implies that biodiesel is inherently clean. Not only does the name imply biodiesel is cl
What is in Diesel and How is Diesel Made from Crude Oil
“What is in diesel?” is a question with two answers, one very short and the other very long. The short answer is hydrocarbons. Hydrocarbons, as the name implies, are molecules made of hydrogen and carbon atom bonds. Hydrocarbons are the components of every fossil fuel — and biofuel — that ma
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
What is Diesel Fuel After All?
An In-Depth Explanation of Diesel Versus Other Fossil Fuels The first things that spring to mind for most people when they think of diesel are semi-tractor trailers and heavy equipment. Most people associate diesel fuel with big, powerful engines that have a deep rumble and can do extraordinary thin
Diesel, the Best Fossil Fuel
Comparing Diesel to Gasoline, Natural Gas, and Coal for Quality, Utility, and Availability There are three categories of fossil fuels: solid, gas, and liquid. Of all the solid fossil fuels; the gas fossil fuels; and the liquid fossil fuels, diesel has the highest energy-production-to-low-emissions r
