Forklift Engine - An engine, otherwise known as a motor, is a tool which changes energy into functional mechanical motion. Motors which change heat energy into motion are referred to as engines. Engines come in several types like for example external and internal combustion. An internal combustion engine usually burns a fuel together with air and the resulting hot gases are utilized for generating power. Steam engines are an example of external combustion engines. They utilize heat to generate motion using a separate working fluid.
In order to generate a mechanical motion through different electromagnetic fields, the electrical motor has to take and create electrical energy. This particular type of engine is extremely common. Other types of engine can be driven making use of non-combustive chemical reactions and some would make use of springs and be driven through elastic energy. Pneumatic motors are driven through compressed air. There are other styles based on the application required.
ICEs or Internal combustion engines
An ICE happens whenever the combustion of fuel mixes with an oxidizer inside a combustion chamber. Inside an internal combustion engine, the increase of high pressure gases mixed along with high temperatures results in applying direct force to some engine parts, for instance, turbine blades, nozzles or pistons. This force produces functional mechanical energy by moving the component over a distance. Usually, an internal combustion engine has intermittent combustion as seen in the popular 2- and 4-stroke piston motors and the Wankel rotary engine. Most jet engines, gas turbines and rocket engines fall into a second class of internal combustion motors called continuous combustion, that happens on the same previous principal described.
External combustion engines such as Stirling or steam engines vary significantly from internal combustion engines. External combustion engines, where the energy is delivered to a working fluid such as pressurized water, liquid sodium and hot water or air that are heated in some kind of boiler. The working fluid is not mixed with, having or contaminated by combustion products.
A range of designs of ICEs have been created and placed on the market along with numerous weaknesses and strengths. If powered by an energy dense gas, the internal combustion engine produces an effective power-to-weight ratio. Even if ICEs have succeeded in many stationary utilization, their actual strength lies in mobile utilization. Internal combustion engines control the power supply for vehicles like for instance cars, boats and aircrafts. Several hand-held power equipments make use of either ICE or battery power equipments.
External combustion engines
In the external combustion engine is made up of a heat engine working with a working fluid such as gas or steam that is heated by an external source. The combustion will occur through the engine wall or through a heat exchanger. The fluid expands and acts upon the engine mechanism that generates motion. After that, 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 be able to supply heat is called "combustion." External thermal engines could be of similar application and configuration but use a heat supply from sources like for instance nuclear, exothermic, geothermal or solar reactions not involving combustion.
Working fluid could be of whatever constitution, even if gas is the most common working fluid. Every so often 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.
