Where is the combustion chamber located on a diesel engine?

But on top of that, each engine’s combustion chamber has a different location. In a typical gasoline engine, the combustion chamber is recessed into the cylinder head(s). In a direct injection diesel engine, the combustion chamber is actually inside the piston.

What is combustion chamber in diesel engine?

A combustion chamber is described for an internal combustion engine, comprising: a main combustion chamber defined by a recess in the top of a piston of the engine, the main combustion chamber being formed with its opening diameter progressively enlarged downwards in the axial direction of the main combustion chamber, …

Where is the combustion chamber located?

Spark-ignition engines

In spark ignition engines, such as petrol (gasoline) engines, the combustion chamber is usually located in the cylinder head. The engines are often designed such that the bottom of combustion chamber is roughly in line with the top of the engine block.

Does diesel engine have combustion chamber?

Diesel combustion. The diesel engine is an intermittent-combustion piston-cylinder device. It operates on either a two-stroke or four-stroke cycle (see figure); however, unlike the spark-ignition gasoline engine, the diesel engine induces only air into the combustion chamber on its intake stroke.

What is a combustion chamber and where is it located?

A Combustion Chamber is the area within the Cylinder where the fuel/air mix is ignited. As the Piston compresses the fuel/air mix and makes contact with the Spark Plug, the mixture is combusted and pushed out of the Combustion Chamber in the form of energy.

What causes combustion in a diesel engine?

The engine consists of a fixed cylinder and a moving piston. … After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke. In a diesel engine, only air is inducted into the engine and then compressed.

What does the blue smoke in diesel engine indicate?

What does the blue smoke in diesel engine indicate? Explanation: Blue smoke comes out from the exhaust when there is unburnt oil in the diesel engine. A very thin layer of the oil gets deposited on the cylinder wall to provide the lubrication between the walls and the moving piston.

What will happen if there is no combustion chamber in the gas turbine plant?

One disadvantage of this method is that fuel may auto-ignite or otherwise combust before the fuel-air mixture reaches the combustion zone. If this happens the combustor can be seriously damaged. Most igniters in gas turbine applications are electrical spark igniters, similar to automotive spark plugs.

Is the way air fuel mixture moves inside a combustion chamber?

The compression stroke is when the trapped air-fuel mixture is compressed inside the cylinder. The combustion chamber is sealed to form the charge. The charge is the volume of compressed air-fuel mixture trapped inside the combustion chamber ready for ignition.

Does combustion increase pressure?

Temperature and pressure in the combustion chamber both increase during the combustion process. The final value of the pressure depends on a temperature factor times the initial value of the pressure. … That is why we compress the gas as much as possible before combustion.

What are the problems with diesel engines?


  • Difficult start. As a diesel owner, you know that they may crank a bit when started. …
  • Lack of power. Lack of power in a diesel pickup is a common fuel-related problem. …
  • Contaminated fuel. …
  • Faulty lead/acid storage battery. …
  • Black exhaust. …
  • Oil oxidation. …
  • Incorrect weight viscosity. …
  • An overabundance of noise.

What did the first diesel engine run on?

Direct injection The first MAN diesel engine operated with direct injection, whereby the fuel was forced directly into the combustion chamber via a nozzle. This engine used as its fuel a very light oil, which was injected by a compressor into the combustion chamber.

What is not a part of diesel engine?

A penstock is not a part of diesel engine power plant.

What are the two types of combustion?

Chemistry and Physics of Fire and Liquid Fuels

Combustion is applicable to two types of fire: Flaming combustion and smoldering combustion [13]. It is important to have a good understanding of the chemical mechanisms of each of these types of fire.

What are the stages of combustion?

On the basis of Recardo experiment, there are three stages of combustion in SI engine as given below: Preparation phase. Flame propagation phase. After burning.

  • Preparation Phase. The preparation phase is also called a period of ignition lag. …
  • Flame Propagation Phase. …
  • After Burning.


What does combustion mean?

Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
