Fuel Injection Systems. The domain of internal-combustion engines also includes such exotic devices as supersonic combustion ramjet engines (scramjets), such as those proposed for hypersonic aircraft, and sophisticated rocket engines and motors, such as those used on U.S. Stationary Internal Combustion Engines Stationary Internal Combustion Engines. Alternative Fuels, Combustion in SI and CI Engines. Spark-ignition engines also are used in the aeronautics industry however, aircraft gas turbines have become the prime movers in this sector because of the emphasis of the aeronautics industry on range, speed, and passenger comfort. Basically, an internal combustion engine transforms the thermal energy of the burning air-fuel mixture into mechanical energy. In these early designs, the engine was used as a gasifier for a single stage turbine (Underwood 1957, Klotsch 1959).

In the 1950s, experiments were conducted with free piston engines in automotive applications. This is because of its outstanding performance as a prime mover in the ground transportation industry. The use of free pistons in internal combustion engines has been investigated for quite some time. The most common internal-combustion engine is the four-stroke, gasoline-powered, homogeneous-charge, spark-ignition engine.

In turboprop engines (bottom) the hot gases drive a turbine, which powers the compressor and propeller, and provide jet thrust. Some air taken in by the turbofan (top) goes to the compressor the rest bypasses the main engine. Each is bounded by the cylinder head, the cylinder and the piston. Britannica Explains In these videos, Britannica explains a variety of topics and answers frequently asked questions. A cars internal combustion engine generally comprises several combustion chambers.

This Time in History In these videos, find out what happened this month (or any month!) in history. Internal combustion (IC) engines operating on fossil fuel oil provide about 25 of the world’s power (about 3000 out of 13,000 million tons oil equivalent per yearsee Figure 1), and in doing so, they produce about 10 of the world’s greenhouse gas (GHG) emissions ().#WTFact Videos In #WTFact Britannica shares some of the most bizarre facts we can find.Demystified Videos In Demystified, Britannica has all the answers to your burning questions.Britannica Classics Check out these retro videos from Encyclopedia Britannica’s archives.
