Forklift Engine - Likewise called a motor, the engine is a device which could change energy into a useful mechanical motion. When a motor converts heat energy into motion it is typically referred to as an engine. The engine could come in many types like the external and internal combustion engine. An internal combustion engine usually burns a fuel together with air and the resulting hot gases are used for generating power. Steam engines are an example of external combustion engines. They utilize heat to produce motion utilizing a separate working fluid.
The electric motor takes electrical energy and produces mechanical motion via various electromagnetic fields. This is a typical type of motor. Various types of motors are driven by non-combustive chemical reactions, other types could use springs and be driven through elastic energy. Pneumatic motors are driven by compressed air. There are various designs based on the application needed.
ICEs or Internal combustion engines
Internal combustion happens whenever the combustion of the fuel mixes along with an oxidizer inside the combustion chamber. Inside the IC engine, higher temperatures will result in direct force to certain engine components like for instance the pistons, turbine blades or nozzles. This force produces useful mechanical energy by way of moving the component over a distance. Normally, an internal combustion engine has intermittent combustion as seen in the popular 2- and 4-stroke piston engines and the Wankel rotating engine. Most rocket engines, jet engines and gas turbines fall into a second class of internal combustion engines known as continuous combustion, which takes place on the same previous principal described.
External combustion engines like Stirling or steam engines vary very much from internal combustion engines. External combustion engines, wherein the energy is delivered to a working fluid like for instance hot water, pressurized water, and liquid sodium or air that are heated in some sort of boiler. The working fluid is not mixed with, consisting of or contaminated by burning products.
A variety of designs of ICEs have been developed and placed on the market with numerous strengths and weaknesses. When powered by an energy dense gas, the internal combustion engine produces an efficient power-to-weight ratio. Even if ICEs have succeeded in several stationary utilization, their actual strength lies in mobile utilization. Internal combustion engines control the power supply intended for vehicles such as boats, aircrafts and cars. Several hand-held power equipments use either ICE or battery power equipments.
External combustion engines
An external combustion engine uses a heat engine where a working fluid, such as steam in steam engine or gas in a Stirling engine, is heated through combustion of an external source. This particular combustion happens via a heat exchanger or through the engine wall. The fluid expands and acts upon the engine mechanism that produces motion. Next, the fluid is cooled, and either compressed and reused or thrown, and cool fluid is pulled in.
Burning fuel utilizing the aid of an oxidizer in order to supply the heat is called "combustion." External thermal engines can be of similar operation and configuration but use a heat supply from sources like for instance nuclear, exothermic, geothermal or solar 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 sometimes utilized. In Organic Rankine Cycle or in the case of the steam engine, the working fluid changes phases between gas and liquid.
