There could be a few things that can cause this humming sound. It could be the wheel bearings rubbing, it could be the gears rubbing, it could even be coming from the engine pistons.?æ
Steam turbines are external combustion engines.
A small amount of rubbing alcohol mixed with gas should not hurt your cars engine. The alcohol will burn with no problems.
No, it is not recommended to put rubbing alcohol in a diesel engine. Rubbing alcohol is not formulated for use as a fuel additive and can cause damage to the engine. It's best to use diesel fuel additives that are specifically designed for diesel engines.
There are four causes of the engine failure. The four causes of the engine failure includes engine overheating, lubrication problems, misassembly , and detonation.
This is a heat engine, they come in various types such as internal combustion, external combustion, steam turbines, gas turbines, etc.
The engine parts are rubbing until the engine oil pressure builds up and the oil starts to lube the parts. Old oil, wrong viscosity, or a clogged filter can cause this to be worse than necessary.
A Jet engine contains a series of turbines that accelerate the air that enters the engine. As the air is accelerated it is compressed to a higher density at which point the fuel is able to begin combustion at ambient temperatures. As the engine warms it becomes more efficient as the fuel is pee heated and the compressor is able to spool faster. At higher altitudes the engine becomes more efficient as the initial air density is lowered causing less resistance on the turbines to accelerate the air, thus allowing a higher spool rate with less fuel. Jet engines are very inefficient at sea level when compared to their efficiency at cruising altitudes.
It has evolved into steam turbines etc... which are still used to generate power.
By a generous estimate, they can be about 30% more efficient than a gasoline engine. I assume you mean "are turbines more efficient than piston engines". Depends on the running conditions. At full load, steady running conditions, turbines are better than piston Engines. At varying loads, turbines often do quite poorly.
Industrial turbines have many uses. The primary use of turbines today is Electrical Generation. Small turbines are used to operate pumps, compressors and other machinery, and they are used as propulsion units on most ships. These turbines range in size from 10 hp oil pump drives to 1.5 million horsepower generating units.
No gas in the engine
