Glow fuel is a fuel source used in model engines – generally the same or similar fuels can be used in model airplanes, helicopters, cars and boats. [1] Glow fuel can be burned by very simple two-stroke engines or by more complicated four-stroke engines, and these engines can provide impressive amounts of power for their very small size.
The net result is that to make a given amount of power, more high-octane fuel must be burned in the engine. Lighter and "thinner" fuel also has a lower specific heat, so the practice of running an engine "rich" to use excess fuel to aid in cooling requires richer and richer mixtures as octane increases.
Fuel consumption increases and the Jevons paradox occurs. Inelastic Demand: A 20% increase in efficiency causes a 10% increase in travel. The Jevons paradox does not occur. Economists have observed that consumers tend to travel more when their cars are more fuel efficient, causing a 'rebound' in the demand for fuel. [12]
Greases are typically composed of about 80% lubricating oil, around 5% to 10% thickener, and approximately 10% to 15% additives. In most common greases, the thickener is a light or alkali metal soap, forming a sponge-like structure that encapsulates the oil droplets.
In the fall of 2006, STP fuel additives began being used in Marathon gasolines, likely to compete with Chevron's Techron additive. [4] In 2010, Clorox sold Armor All and STP to Avista Capital Partners. It named the business Armored AutoGroup. In April 2015, the Armored AutoGroup was acquired by Spectrum Brands. [5]
M85 is a fuel consisting of 85% methanol and 15% gasoline (petrol). [1] It is a potential alternative to traditional gasoline and ethanol. M85 is similar to E85, but cannot be used in vehicles designed for E85.
Methanol fuel is also used extensively in drag racing, primarily in the Top Alcohol category, while between 10% and 20% methanol may be used in Top Fuel classes in addition to Nitromethane. Formula One racing continues to use gasoline as its fuel, but in prewar grand prix racing methanol was often used in the fuel.
Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.
