Engines for Forklifts - Also called a motor, the engine is a device that can change energy into a functional mechanical motion. When a motor changes heat energy into motion it is normally called an engine. The engine could come in many types like for example the internal and external combustion engine. An internal combustion engine normally burns a fuel with air and the resulting hot gases are used for creating power. Steam engines are an example of external combustion engines. They utilize heat to generate motion together with a separate working fluid.
The electric motor takes electrical energy and produces mechanical motion via different electromagnetic fields. This is a common type of motor. Some kinds of motors function through non-combustive chemical reactions, other types can use springs and be driven through elastic energy. Pneumatic motors are driven by compressed air. There are other styles based on the application required.
ICEs or Internal combustion engines
Internal combustion occurs when the combustion of the fuel combines along with an oxidizer inside the combustion chamber. In the IC engine, higher temperatures will result in direct force to certain engine components like the turbine blades, nozzles or pistons. This particular force produces functional mechanical energy by moving the component over a distance. Usually, an ICE has intermittent combustion as seen in the popular 2- and 4-stroke piston motors and the Wankel rotary motor. Nearly all gas turbines, rocket engines and jet engines fall into a second class of internal combustion motors called continuous combustion, which takes place on the same previous principal described.
External combustion engines like steam or Sterling engines differ greatly from internal combustion engines. External combustion engines, wherein 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 kind of boiler. The working fluid is not combined with, having or contaminated by combustion products.
A variety of designs of ICEs have been developed and placed on the market with numerous weaknesses and strengths. When powered by an energy dense gas, the internal combustion engine delivers an efficient power-to-weight ratio. Even though ICEs have been successful in a lot of stationary utilization, their actual strength lies in mobile applications. Internal combustion engines dominate the power supply used for vehicles like for example aircraft, cars, and boats. Some hand-held power equipments make use of either battery power or ICE equipments.
External combustion engines
An external combustion engine is comprised of a heat engine wherein 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 combustion occurs via a heat exchanger or through the engine wall. The fluid expands and acts upon the engine mechanism which produces motion. Next, the fluid is cooled, and either compressed and used again or thrown, and cool fluid is pulled in.
The act of burning fuel using an oxidizer to supply heat is referred to as "combustion." External thermal engines could 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 could be of whichever constitution. Gas is the most common kind of working fluid, yet single-phase liquid is occasionally utilized. In Organic Rankine Cycle or in the case of the steam engine, the working fluid adjusts phases between gas and liquid.
