Forklift Engine - Otherwise called a motor, the engine is a device that could transform energy into a useful mechanical motion. When a motor transforms heat energy into motion it is normally referred to as an engine. The engine can be available in numerous kinds like the external and internal combustion engine. An internal combustion engine normally burns a fuel along with air and the resulting hot gases are used for creating power. Steam engines are an example of external combustion engines. They use heat to produce motion along with a separate working fluid.
In order to produce a mechanical motion via varying electromagnetic fields, the electric motor needs to take and create electrical energy. This particular kind of engine is extremely common. Other kinds of engine can function using non-combustive chemical reactions and some would make use of springs and be driven by elastic energy. Pneumatic motors are driven by compressed air. There are different styles based on the application needed.
Internal combustion engines or ICEs
Internal combustion happens whenever the combustion of the fuel combines with an oxidizer in the combustion chamber. In the IC engine, higher temperatures will result in direct force to certain engine parts such as the turbine blades, nozzles or pistons. This force produces functional mechanical energy by moving the part over a distance. Normally, an ICE has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotary engine. The majority of gas turbines, rocket engines and jet engines fall into a second class of internal combustion motors known as continuous combustion, which happens on the same previous principal described.
External combustion engines such as steam or Sterling engines differ significantly from internal combustion engines. External combustion engines, where the energy is delivered to a working fluid like for instance pressurized water, liquid sodium and hot water or air that are heated in some sort of boiler. The working fluid is not combined with, consisting of or contaminated by burning products.
Different designs of ICEs have been developed and are now available with various strengths and weaknesses. If powered by an energy dense gas, the internal combustion engine delivers an efficient power-to-weight ratio. Although ICEs have succeeded in numerous stationary utilization, their actual strength lies in mobile applications. Internal combustion engines dominate the power supply meant for vehicles such as cars, boats and aircrafts. Some hand-held power tools use either battery power or ICE devices.
External combustion engines
An external combustion engine utilizes a heat engine where a working fluid, like for instance steam in steam engine or gas in a Stirling engine, is heated by combustion of an external source. This particular combustion takes place through a heat exchanger or via the engine wall. The fluid expands and acts upon the engine mechanism which produces motion. After that, the fluid is cooled, and either compressed and used again or disposed, and cool fluid is pulled in.
The act of burning fuel along with an oxidizer to be able to supply heat is referred to as "combustion." External thermal engines may be of similar application and configuration but use a heat supply from sources such as geothermal, solar, nuclear or exothermic reactions not involving combustion.
The working fluid can be of any composition. Gas is the most common type of working fluid, yet single-phase liquid is sometimes used. In Organic Rankine Cycle or in the case of the steam engine, the working fluid varies phases between gas and liquid.
