Is a diesel engine An internal combustion engine?

Is a diesel engine internal or external combustion?

Four-stroke Diesel and petrol (gasoline) engines are internal combustion engines. In these engines, the fluid undergoes combustion inside the cylinder and expands.

How are diesel engines classified?

One classification of internal combustion diesel engines is based on the type of the engine cycle—diesel engines can operate either on (1) the two-stroke cycle or (2) the four-stroke cycle. … There are two basic combustion chamber configurations for diesel engines: (1) the direct- and (2) the indirect-inject designs.

Which type of engine is classified as internal combustion?

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine.

What are examples of external combustion engine?


  • CANDU reactor (a type of nuclear power plant)
  • coal-fired power plant.
  • natural gas power plant.
  • steam locomotive (although there are very few operational examples left)
  • Solar thermal power plant.
  • Stirling engine.

Which is better internal or external combustion engine?

In IC engines, the combustion of fuel takes place inside, whereas in EC engines the fuel combustion takes place outside the cylinder. The advantages of IC engine are higher BTE, more horsepower developed per unit weight and low cost compared to that of external combustion engine.

What are the 3 types of diesel?

Diesel fuels are broken up into 3 different classes: 1D(#1), 2D(#2) and 4D(#4). The difference between these classes depends on viscosity (the property of a fluid that causes a resistance to the fluid’s flow) and pour point (the temperature at which a fluid will flow). #4 fuels tend to be used in low-speed engines.

What are the three basic size groups of diesel engine?

There are three basic size groups of diesel engines based on power—small, medium, and large.
