Not very.
only about 15% of the energy is used to drive your car on the road.
62% of the energy is used up in the engine itself, converting the gas to energy.
17% is used when the vehicle idles.
5% is expended in the transmission
2% is used for accessories.
Internal combustion engine.
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
The internal combustion engine give rise to the auto industry.
A steam engine is an external combustion engine.
Not totally, just because it is an internal combustion engine doesn't exactly mean that fossil fuels need to be burnt. The concept of the Internal Combustion engine is relatively reuseable, the major problem with it is its efficiency. As we all know a good petrol engine will probably get around 25 - 30% efficiency as in driving force. The rest is lost mostly to either friction or heat. If these problems can be rectified the Internal Combustion engine could possibly run on fossil fuels for another century (Oil depending/Government b*llshit). Yet fuel cells and other means of power are being developed so this depends on the movement of technology.
The formula to calculate the Otto cycle efficiency is: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio of the working fluid. The Otto cycle efficiency impacts the overall performance of an internal combustion engine by determining how effectively it converts the energy from fuel into mechanical work. A higher efficiency means that more of the energy from the fuel is being used to power the engine, resulting in better fuel economy and performance.
The thermal efficiency of the Otto cycle is important for internal combustion engines because it measures how effectively the engine converts heat from fuel into mechanical work. A higher thermal efficiency means the engine is more efficient at converting fuel into useful energy, leading to better performance and fuel economy. This is crucial for reducing emissions and improving overall engine performance.
a gasoline engine is an Internal combustion engine
Internal combustion engine.
and internal combustion engine and a gasoline engine are the same thing.
Reciprocating engines (piston engines) are internal combustion engines. Rotary engines ( Wankel engine) is also an internal combustion engine. In general, all types of engines in which the combustion chamber is an integrating part of the engine is considered a internal combustion engine.
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
combustion engine
The four-stroke engine used in automobiles is an example of an internal combustion engine.
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
Internal combustion engines are now operating at about 30-40 % efficiency with the application of computer controls and continues to get better all the time. I am not sure of the efficiency rating of external combustion or central combustion engines. I will make an attemp to find out. Note that these engines to my knowledge are only used by the military in torpedoes so I am not sure if there is any info available to the general public. I have seen electric motors up to 55% efficiency. I am not sure if there are more efficient motors out there but I would bet yes.
The thermal efficiency of an internal combustion engine using the Otto cycle is a measure of how effectively it converts heat energy from fuel into mechanical work. The Otto cycle, which consists of four processes (intake, compression, power, and exhaust), plays a key role in determining the engine's thermal efficiency. By optimizing the compression ratio and combustion process within the Otto cycle, engineers can improve the engine's thermal efficiency, resulting in better fuel economy and performance.
