Low octane commercial and aviation gasoline could be used if engine oil was added, jet fuel Jet A, B, JP-4, 5, 7, and 8 could be used, as well as fuel oil #1 and #2. [5] In practice, they only used diesel fuel, their tactical advantage was never needed, and in time they were replaced with commercial diesel engines.
Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). [1] By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50–50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel.

Jet fuel is more expensive than diesel fuel but the logistical advantages of using one fuel can offset the extra expense of its use in certain circumstances. Jet fuel contains more sulfur, up to 1,000 ppm, which therefore means it has better lubricity and does not currently require a lubricity additive as all pipeline diesel fuels require.
The most common combustion cycle for aero engines is the four-stroke with spark ignition. Two-stroke spark ignition has also been used for small engines, while the compression-ignition diesel engine is seldom used. Starting in the 1930s attempts were made to produce a practical aircraft diesel engine. In general, Diesel engines are more ...
Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. [1] In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced ...
A tank of diesel fuel on a truck. Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.
For combustion engines to use 100 percent hydrogen, they need components that can withstand high temperatures and corrosive environments. Scientists from the University of Alberta discovered a new ...
Kerosene is used in kerosene lamps and as a fuel for cooking, heating, and small engines. It displaced whale oil for lighting use. Jet fuel for jet engines is made in several grades (Avtur, Jet A, Jet A-1, Jet B, JP-4, JP-5, JP-7 or JP-8) that are kerosene-type mixtures. One form of the fuel known as RP-1 is burned with liquid oxygen as rocket ...
