Forklift Engine - Also called a motor, the engine is a tool which can transform energy into a useful mechanical motion. When a motor changes heat energy into motion it is usually called an engine. The engine could be available in various types like the internal and external combustion engine. An internal combustion engine normally burns a fuel making use of air and the resulting hot gases are utilized for creating power. Steam engines are an example of external combustion engines. They use heat to produce motion together with a separate working fluid.
The electric motor takes electrical energy and generates mechanical motion through varying electromagnetic fields. This is a typical type of motor. Some kinds of motors function by non-combustive chemical reactions, other types could utilize springs and be driven by elastic energy. Pneumatic motors function by compressed air. There are other designs based upon the application required.
Internal combustion engines or ICEs
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 for instance the nozzles, pistons, or turbine blades. This force produces useful mechanical energy by moving the component over a distance. Usually, an internal combustion engine has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotating engine. The majority of jet engines, gas turbines and rocket engines fall into a second class of internal combustion engines known as continuous combustion, that occurs on the same previous principal described.
Steam engines or Stirling external combustion engines significantly differ from internal combustion engines. The external combustion engine, where energy is to be delivered to a working fluid such as pressurized water, hot water, liquid sodium or air that is heated in a boiler of some sort. The working fluid is not combined with, consisting of or contaminated by combustion products.
A variety of designs of ICEs have been created and placed on the market along with numerous weaknesses and strengths. When powered by an energy dense fuel, the internal combustion engine provides an effective power-to-weight ratio. Even if ICEs have succeeded in several stationary applications, their actual strength lies in mobile applications. Internal combustion engines control the power supply utilized for vehicles like for example aircraft, cars, and boats. Some hand-held power gadgets utilize either battery power or ICE gadgets.
External combustion engines
In the external combustion engine is made up of a heat engine working with a working fluid like for instance gas or steam that is heated by an external source. The combustion will occur through the engine wall or via a heat exchanger. The fluid expands and acts upon the engine mechanism which generates motion. Next, the fluid is cooled, and either compressed and used again or discarded, and cool fluid is pulled in.
The act of burning fuel along with an oxidizer so as to supply heat is called "combustion." External thermal engines may be of similar operation and configuration but make use of a heat supply from sources like for instance solar, nuclear, exothermic or geothermal reactions not involving combustion.
The working fluid can be of whichever composition. Gas is the most common kind 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 changes phases between gas and liquid.
