• Examples of engines that ...read more

Exhaust is the waste gases or steam expelled from an engine, turbine, or other machine.

• Exhaust is produced when fuel is burned in an engine.

• It contains harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter.

• Exhaust systems in vehicles are designed to reduce emissions and noise.

• Exhaust gases can also be used to power turbines and generate electricity.

• Regular maintenance of exhaust systems is important to ensure proper functioning and prevent leaks.

An engine is a machine that converts fuel into mechanical energy to power vehicles or machinery.

• Engines come in various types such as internal combustion, diesel, electric, and hybrid.

• They are used in cars, trucks, airplanes, boats, generators, and more.

• The engine's main components include cylinders, pistons, crankshaft, and camshaft.

• The engine's power output is measured in horsepower (hp) or kilowatts (kW).

AC stands for Alternating Current.

• AC is a type of electrical current that periodically reverses direction.

• It is commonly used in household appliances and power transmission.

• AC voltage and frequency vary depending on the country and region.

• AC can be converted to DC (Direct Current) using a rectifier.

• AC is measured in units of Hertz (Hz).
