Diesel Emissions: What They Are and What Are Their Consequences
Diesel emissions recently made headlines when it was discovered automobile manufacturers were cheating diesel emissions tests. In 2015, evidence surfaced that Volkswagen was cheating on diesel-engine emissions tests. According to the Financial Times, John German — a senior fellow at the Internatio
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
Myths about Diesel and Diesel Engines Debunked
An American Scientific subscriber wrote to the magazine and asked why European cars are not available in the United States. What prompted the question is the fact that many European passengers, “cars are more efficient and better for the environment.” The answer received was short. According to
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
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
Fuel Catalyst: What is a Fuel Catalyst and What Does a Fuel Catalyst Do?
A fuel catalyst is a pre-combustion mechanical device that increases fuel efficiency and decreases emissions. There are both diesel fuel catalysts and fuel catalysts for gasoline. Because of the difference in density between fossil fuels, fuel catalysts have varying degrees of impact with respect to
Diesel Emissions: Types and Effects of Diesel Engine Emissions
Diesel emissions compared to gasoline, biodiesel, ethanol, propane, and natural gas is debated with regard to least/most and safest/worse. With respect to fuel efficiency, there is no debate. Diesel engines are far more fuel efficient than gasoline engines of comparable size. In fact, diesel engines
Gasoline vs Diesel Emissions: Types and Effects of Each on Health & Environment
Gasoline vs diesel emissions is a comparison measured by an accounting for fuel economy, fuel composition, and engine-type combustion characteristics. It is not unreasonable to assume that gasoline and diesel engines produce the same emissions. After all, both gasoline and diesel are hydrocarbon bas
