"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 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.
Function of internal-combustion engine?
to produce mechanical energy
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.
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.
What type pf fuel uses combustion to produce energy?
Gasoline and diesel are two common types of fuel that use combustion to produce energy. During combustion, these fuels react with oxygen to release heat energy that powers engines.
Machine that transforms heat into mechanical energy?
A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine. Real engines, that obviously work at a lesser efficiency, include the combustion engines found in cars.A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine.

How is petroleum converted into usuable energy?
Petroleum is refined into various products like gasoline and diesel through a process called refining. These products are then used in combustion engines to generate energy, which is converted into mechanical work or electricity. The energy stored in petroleum is released through combustion, where the hydrocarbons in the fuel react with oxygen to produce heat, which is then used to power engines and generate electricity.
Why does different types of vehicle engines produce different exhaust emissions?
For instance diesel engines use compression for combustion versus spark plugs which are used in everyday vehicle engines. Some engines use different fuels therefore when combustion occurs the exhaust produces emissions based on the fuel mixture.
