explain different types of combustion.
Answers
Explanation:
Combustion is the act of burning, in which fuel, heat and oxygen release energy. There are several types of combustion, such as internal combustion, diesel combustion, low temperature combustion and other novel forms.
Answer:
Types of Combustion
Internal combustion is a common type of combustion. This type of combustion happens inside an engine, which is why that type of engine is called an "internal combustion engine." Most of the vehicles you will see on roads are powered by internal combustion.
Diesel combustion involves spraying jets of fuel into a compression heating system that ignites and makes a flame.
Clean diesel combustion occurs in a similar manner to regular diesel combustion. The main difference is there is more fuel and air mixing prior to ignition. Less soot results from this efficient combustion, as well as less nitrogen oxide pollution.
Homogenous charge compression ignition (HCCI) is an advanced form of combustion that works at a lower temperature. Before it is compressed, fuel is vaporized and mixed with air before being sprayed and compression-heated. This type of combustion is considered highly efficient because it does not yield soot.
Low-temperature combustion (LTC) is a lower temperature flameless combustion. A diluted fuel-air mixture is compressed until it autoignites. Diluting the fuel mix means less fuel is needed, making this form of combustion more efficient than diesel combustion. Another benefit to LTC is the control of autoignition timing and the heat-release rate. Having a lower temperature also means the engine will not lose as much energy to its surroundings. The engine can work longer, and will not knock as in spark ignition. This can reduce engine noise and damage.
