Sistem Pembakaran Mesin Internal

Internal combustion engine combustion engines where the fuel (generally, fossil fuels) has occurred with the oxidizer in the combustion chamber. In an internal combustion engine and high temperature expansion of the gas pressure, generated by combustion, directly apply force to move machine components, such as turbine blades or pistons and move distance, yielding useful mechanical energy.

The term usually refers to the internal combustion engine on the engine where combustion intermittent, such as the more familiar four-stroke and two-stroke piston engine, along with variants, such as the Wankel rotary engine. A second class of internal combustion engines use a continuous combustion: gas turbines, jet engines and most rocket engines, each of which is an internal combustion engine on the same principles as described previously.

Internal combustion engine (or ICE) is very different from the external combustion engine, such as steam or Stirling engines, where the energy sent to the working fluid which does not consist of, mixed with or contaminated by combustion products. working fluid can be air, hot water, pressurized water or even liquid sodium, is heated in some type of boiler with fossil fuels, burning wood, nuclear, solar etc.

A large number of different designs for ICES has developed and built, with different strengths and different weaknesses. Backed by solid fuel energy (which is very often gasoline, liquid derived from fossil fuels), ICE provides the ratio of the power-to-weight very well with little or other security weaknesses. Although there are still many applications and stationary, the true power of internal combustion engines in mobile applications and they dominate as power supplies for cars, planes, and boats, from smallest to largest. Only for handheld power tools they share part of the market with a battery-powered devices.
