Forklift Engine - Otherwise known as a motor, the engine is a device that can change energy into a functional mechanical motion. When a motor transforms heat energy into motion it is normally referred to as an engine. The engine could come in several kinds like for instance the internal and external combustion engine. An internal combustion engine normally burns a fuel using air and the resulting hot gases are utilized for generating power. Steam engines are an illustration of external combustion engines. They make use of heat to be able to generate motion with a separate working fluid.
The electrical motor takes electrical energy and produces mechanical motion through different electromagnetic fields. This is a common kind of motor. Some kinds of motors are driven through non-combustive chemical reactions, other types can use springs and be driven through elastic energy. Pneumatic motors are driven through compressed air. There are other designs based upon the application needed.
Internal combustion engines or ICEs
Internal combustion occurs whenever the combustion of the fuel mixes together 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 moving the component over a distance. Typically, an ICE has intermittent combustion as seen in the popular 2- and 4-stroke piston motors and the Wankel rotating motor. The majority of rocket engines, jet engines and gas turbines fall into a second class of internal combustion motors called continuous combustion, that happens on the same previous principal described.
Steam engines or Stirling external combustion engines greatly differ from internal combustion engines. The external combustion engine, wherein energy is to be delivered to a working fluid like for instance hot water, liquid sodium, pressurized water or air that is heated in a boiler of some sort. The working fluid is not mixed 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. If powered by an energy dense fuel, the internal combustion engine produces an effective power-to-weight ratio. Even if ICEs have succeeded in various stationary applications, their real strength lies in mobile applications. Internal combustion engines control the power supply used for vehicles such as boats, aircrafts and cars. A few hand-held power equipments make use of either battery power or ICE gadgets.
External combustion engines
An external combustion engine is comprised of a heat engine where a working fluid, like for example steam in steam engine or gas in a Stirling engine, is heated through 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 that generates motion. Then, the fluid is cooled, and either compressed and used again or thrown, and cool fluid is pulled in.
The act of burning fuel with an oxidizer to supply heat is called "combustion." External thermal engines could be of similar application and configuration but utilize a heat supply from sources like for example geothermal, solar, nuclear or exothermic reactions not involving combustion.
The working fluid could be of whichever composition. Gas is actually the most common kind 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 adjusts phases between liquid and gas.
