"External combustion engine" almost always means a steam engine. There are two kinds.
Reciprocating steam engines have a boiler to make steam, a piston assembly for the steam to act against, and a flywheel for the piston assembly to turn. The first steam engines were "single acting" engines. You introduce steam into the piston assembly. When it reaches the bottom of its travel, the rotating flywheel forces the piston back to the top. This is how single-cylinder internal combustion engines work. That's not efficient because you rely on mechanical inertia to make the engine work, so someone invented the "double acting" engine. The piston assembly has two pistons in it. When the piston on the left side reaches the bottom of its stroke the one on the right has reached the top of its, and a valve switches the steam from the left piston to the right one. This is far more efficient, and it's how any internal combustion engine with more than one cylinder works. To get useful work out of this thing, you put a big drive belt around the flywheel.
Steam turbines are a lot like jet engines, except that jet engines don't have boilers. There are two kinds of turbine wheels, and every steam turbine contains both types. One kind has blades that you shoot steam against. The other kind has nozzles that steam shoots out of. The guy who invented this motor knew the first wheel wouldn't use all the energy in the steam, so he captured the steam used on the first wheel to drive a second, and he kept going until all the usable energy had been extracted from the steam. The shaft of the steam turbine directly drives the load.
What else can I help you with?
Does external combustion engines use turbines?
No,they use engines to produce mechanical energy.
How are internal combustion engines similar to external combustion engines?
Internal combustion engines and external combustion engines both convert fuel into mechanical energy through combustion. In both types, the combustion process generates heat, which is then used to produce work, typically by moving a piston or rotating a turbine. They also share similar components, such as cylinders, valves, and fuel delivery systems, although their operational processes differ in where combustion occurs. Ultimately, both types aim to harness energy from fuel for various applications like powering vehicles or machinery.
what is a heater an internal combustion engine or a external combustion engine?
A heater can be either an internal combustion engine or an external combustion engine, depending on its design and operation. Internal combustion engines generate heat through the combustion of fuel within the engine itself, while external combustion engines produce heat by burning fuel outside the engine to heat a working fluid. Common examples of heaters include furnaces (external combustion) and car engines (internal combustion). The specific classification depends on how and where the combustion occurs in relation to the heat-producing mechanism.
How can chemical energy be converted into mechanical energy?
Engines use fuel to produce mechanical energy. For instance, a car's internal combustion engine uses chemical energy stored in fuel to turn a drive shaft.The idea of internal combustion is to burn the compressed mixture of fuel and air to produce expanding gas to convert into mechanical energy.
Do diesel engines produce carbon monoxide?
Yes, diesel engines produce carbon monoxide as a byproduct of combustion.
What objects that produce mechanical energy?
Some examples of objects that produce mechanical energy are steam turbines, wind turbines, water wheels, and internal combustion engines. These objects convert various forms of energy (such as steam, wind, water flow, or fuel combustion) into mechanical energy that can be used to perform work.
How does an external combustion engine work?
An external combustion engine (EC engine) is a heat engine where an fuel is burned outside the engine, which heats an internal working fluid. The fluid expands and drives the engine to produce motion or usable work. Conversely, internal combustion engines burn or explode the fuel within the engine, using the expanding exhaust gases to do work. Examples of external combustion engines are coal and oil-fired boilers on ships and in locomotives, and the "Stanley Steamer, " an early steam-powered motorcar.
Function of internal-combustion engine?
to produce mechanical energy
What device can convert heat to machinical energy?
A device that converts heat to mechanical energy is called a heat engine. Heat engines operate by using thermal energy from a heat source to perform work, usually through a cyclic process involving the expansion and contraction of gases or fluids. Common examples include steam engines and internal combustion engines, which harness heat from fuel combustion to produce mechanical power.
What is the difference between internal combustion engine and external combustion engine?
In an Internal Combustion Engine, the Fuel is burnt in the cylinder or vessel eg. Diesel or Petrol engine used in Cars.Gasoline engines, Wankel engines, diesels, gas turbines are all examples of internal combustion.In an External Combustion Engine, the internal working fuel is not burnt. Here the fluid is being heated from an external source. The fuel is heated and expanded through the internal mechanism of the engine resulting in work. eg. Steam Turbine, Steam engine Trains.
Why petrol engines produce oxides of nitrogen?
Petrol engines produce oxides of nitrogen (NOx) as a byproduct of combustion at high temperatures. Specifically, nitrogen in the air reacts with oxygen in the engine's combustion chamber to form NOx gases. Factors such as high compression ratios and combustion temperatures can contribute to increased NOx emissions from petrol engines.
Comparison between IC and EC engine?
Internal combustion (IC) engines generate power by burning fuel within the engine itself, converting the chemical energy of fuel into mechanical energy through a series of controlled explosions. In contrast, external combustion (EC) engines burn fuel outside the engine, using the heat generated to produce steam or gas that drives a piston or turbine. IC engines are typically more compact and efficient for automotive applications, while EC engines, such as steam engines, can utilize a variety of fuels and are often used in power generation. Overall, IC engines are more prevalent in personal and commercial vehicles, while EC engines are found in specific industrial applications.
