Forklift Engine - Also referred to as a motor, the engine is a tool that can change energy into a useful mechanical motion. Whenever a motor transforms heat energy into motion it is usually known as an engine. The engine can come in various kinds like for instance the internal and external combustion engine. An internal combustion engine typically burns a fuel using air and the resulting hot gases are utilized for creating power. Steam engines are an illustration of external combustion engines. They make use of heat to generate motion using a separate working fluid.
The electrical motor takes electrical energy and generates mechanical motion through various electromagnetic fields. This is a typical kind of motor. Several types of motors function through non-combustive chemical reactions, other types can make use of springs and be driven through elastic energy. Pneumatic motors are driven through compressed air. There are different designs based upon the application required.
ICEs or Internal combustion engines
Internal combustion occurs whenever the combustion of the fuel combines along with an oxidizer inside the combustion chamber. In the IC engine, higher temperatures would result in direct force to certain engine components like the turbine blades, nozzles or pistons. This force produces useful mechanical energy by way of moving the part over a distance. Typically, an internal combustion engine has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotating engine. Most gas turbines, rocket engines and jet engines fall into a second class of internal combustion motors known as continuous combustion, that takes place on the same previous principal described.
Steam engines or Stirling external combustion engines very much differ from internal combustion engines. The external combustion engine, where energy is to be delivered to a working fluid like for instance liquid sodium, pressurized water, hot water or air that is heated in a boiler of some type. The working fluid is not mixed with, having or contaminated by combustion products.
Various designs of ICEs have been created and are now available along with numerous weaknesses and strengths. If powered by an energy dense fuel, the internal combustion engine produces an efficient power-to-weight ratio. Although ICEs have been successful in numerous stationary utilization, their real strength lies in mobile applications. Internal combustion engines control the power supply meant for vehicles like for example boats, aircrafts and cars. Several hand-held power gadgets use either battery power or ICE equipments.
External combustion engines
In the external combustion engine is made up of a heat engine working using a working fluid like for example gas or steam that is heated by an external source. The combustion would happen via the engine wall or through a heat exchanger. The fluid expands and acts upon the engine mechanism which generates motion. Then, the fluid is cooled, and either compressed and used again or disposed, and cool fluid is pulled in.
Burning fuel with the aid of an oxidizer to be able to supply the heat is referred to as "combustion." External thermal engines may be of similar operation and configuration but use a heat supply from sources such as exothermic, geothermal, solar or nuclear reactions not involving combustion.
The working fluid can be of any constitution. Gas is actually the most common type of working fluid, yet single-phase liquid is occasionally used. In Organic Rankine Cycle or in the case of the steam engine, the working fluid varies phases between liquid and gas.
