Forklift Engine - Likewise referred to as a motor, the engine is a tool that can transform energy into a functional mechanical motion. When a motor converts heat energy into motion it is usually referred to as an engine. The engine can be available in numerous types like for instance the internal and external combustion engine. An internal combustion engine typically burns a fuel utilizing air and the resulting hot gases are used for generating power. Steam engines are an example of external combustion engines. They use heat to be able to generate motion along with a separate working fluid.
In order to generate a mechanical motion through various electromagnetic fields, the electric motor needs to take and create electrical energy. This particular kind of engine is extremely common. Other kinds of engine could function making use of non-combustive chemical reactions and some will use springs and function through 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 when the combustion of the fuel mixes along with an oxidizer in the combustion chamber. Inside 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 component over a distance. Typically, an ICE has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotating motor. Nearly all jet engines, gas turbines and rocket engines fall into a second class of internal combustion engines called continuous combustion, that happens on the same previous principal described.
External combustion engines such as steam or Sterling engines vary very much 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 type of boiler. The working fluid is not mixed with, having or contaminated by combustion products.
Different designs of ICEs have been developed and placed on the market along with numerous weaknesses and strengths. When powered by an energy dense fuel, the internal combustion engine delivers an effective power-to-weight ratio. Even if ICEs have been successful in several stationary applications, their real strength lies in mobile utilization. Internal combustion engines control the power supply intended for vehicles like for example boats, aircrafts and cars. Several hand-held power gadgets use either battery power or ICE devices.
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 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. Next, the fluid is cooled, and either compressed and reused or disposed, and cool fluid is pulled in.
Burning fuel with the aid of an oxidizer so as to supply the heat is called "combustion." External thermal engines can be of similar operation and configuration but make use of a heat supply from sources such as solar, nuclear, exothermic or geothermal reactions not involving combustion.
The working fluid can be of any constitution. Gas is the most common type 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 liquid and gas.
