Internal combustion engine 82.3.08

An internal combustion engine is a heat engine that converts fuel into mechanical work by burning fuel inside the engine itself.

The main types include spark-ignition engines (such as gasoline engines) and compression-ignition engines (such as diesel engines).

They are generally powerful, have a high energy density, and can run on a variety of fuels.

They produce emissions that contribute to air pollution, are less efficient than electric motors, and rely on fossil fuels.

It works by drawing in air and fuel, compressing them, igniting the mixture to produce energy, and using this energy to move pistons.

Common fuels include gasoline, diesel, biofuels, and alternative fuels such as propane and hydrogen.

Yes, they emit greenhouse gases and pollutants, contributing to climate change and air quality issues.

Internal combustion engines typically have an efficiency of 20-30%, while electric motors can reach efficiencies of over 90%.

The future includes advancements in clean technology, more efficient designs, and potential replacements with electric vehicles.

Regular maintenance includes oil changes, spark plug replacements, air filter checks, and ensuring the cooling system functions properly.
