Engines for Forklift - An engine, otherwise called a motor, is an apparatus which changes energy into useful mechanical motion. Motors that convert heat energy into motion are referred to as engines. Engines come in numerous types like for example external and internal combustion. An internal combustion engine usually burns a fuel with air and the resulting hot gases are utilized for generating power. Steam engines are an example of external combustion engines. They use heat in order to generate motion using a separate working fluid.
The electrical motor takes electrical energy and produces mechanical motion through varying electromagnetic fields. This is a typical kind of motor. Various types of motors are driven by non-combustive chemical reactions, other types can utilize springs and be driven by elastic energy. Pneumatic motors function through compressed air. There are other designs based upon the application needed.
ICEs or Internal combustion engines
Internal combustion occurs when the combustion of the fuel combines along with an oxidizer in the combustion chamber. Inside the IC engine, higher temperatures would result in direct force to certain engine parts like for example the turbine blades, nozzles or pistons. This force produces functional mechanical energy by means of moving the part over a distance. Typically, an internal combustion engine has intermittent combustion as seen in the popular 2- and 4-stroke piston motors and the Wankel rotating motor. Most gas turbines, rocket engines and jet engines fall into a second class of internal combustion engines known as continuous combustion, which occurs 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 such as liquid sodium, pressurized water, hot water or air that is heated in a boiler of some sort. 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 together with various strengths and weaknesses. When powered by an energy dense gas, the internal combustion engine produces an effective power-to-weight ratio. Even though ICEs have succeeded in numerous stationary applications, their real strength lies in mobile utilization. Internal combustion engines control the power supply utilized for vehicles like for example boats, aircrafts and cars. Some hand-held power equipments utilize either battery power or ICE devices.
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 discarded, 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 may be of similar application and configuration but utilize a heat supply from sources like for example exothermic, geothermal, solar or nuclear reactions not involving combustion.
Working fluid could be of whichever composition, even though gas is the most common working fluid. Every now and then a single-phase liquid is sometimes utilized. In Organic Rankine Cycle or in the case of the steam engine, the working fluid adjusts phases between liquid and gas.
