Forklift Engine - Also referred to as a motor, the engine is a device that can change energy into a functional mechanical motion. Whenever a motor changes heat energy into motion it is typically known as an engine. The engine could be available in several kinds like for instance the internal and external combustion engine. An internal combustion engine usually 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 make use of heat to generate motion utilizing a separate working fluid.
In order to produce a mechanical motion through varying electromagnetic fields, the electrical motor should take and produce electrical energy. This kind of engine is extremely common. Other kinds of engine can function utilizing non-combustive chemical reactions and some would use springs and be driven by elastic energy. Pneumatic motors are driven by compressed air. There are other designs based upon the application needed.
ICEs or Internal combustion engines
An ICE happens whenever the combustion of fuel mixes together with an oxidizer in a combustion chamber. In an internal combustion engine, the increase of high pressure gases mixed together with high temperatures results in applying direct force to some engine parts, for instance, pistons, turbine blades or nozzles. This force generates useful mechanical energy by means of moving the component over a distance. Usually, an ICE has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotating motor. Most rocket engines, jet engines and gas turbines fall into a second class of internal combustion motors known as continuous combustion, that happens on the same previous principal described.
External combustion engines like Stirling or steam engines differ greatly from internal combustion engines. External combustion engines, where the energy is delivered to a working fluid like for instance liquid sodium, hot water and pressurized 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 range of designs of ICEs have been created and placed on the market along with various strengths and weaknesses. If powered by an energy dense gas, the internal combustion engine produces an efficient power-to-weight ratio. Even though ICEs have succeeded in several stationary utilization, their actual strength lies in mobile utilization. Internal combustion engines control the power supply meant for vehicles such as boats, aircrafts and cars. Several hand-held power tools utilize either battery power or ICE equipments.
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 combustion happens via a heat exchanger or via the engine wall. The fluid expands and acts upon the engine mechanism that 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 together with an oxidizer so as to supply heat is called "combustion." External thermal engines can 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 could be of any constitution. Gas is the most common type 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 varies phases between liquid and gas.
