We can classify internal combustion reciprocating engines according to the number of strokes of the piston in one complete working cycle. … There is still another classification according to the process of combustion: explosion or constant-volume combustion engines and constant-pressure combustion or Diesel engines.
How are engines classified?
Automotive Engines are generally classified according to following different categories: Internal combustion (IC) and External Combustion (EC) Type of fuel: Petrol, Diesel, Gas, Bio / Alternative Fuels. Number of strokes – Two stroke Petrol, Two-Stroke Diesel, Four Stroke Petrol / Four Stroke Diesel.
How IC engines are classified also how SI engine are classified by valve operation?
A)SI engine :- A spark-ignition engine (SI engine) is an internal combustion engine, usually a petrol engine, where the combustion cycle of an air-fuel mixture is ignited by a spark plug. B)CI engine :- A CI engine is type of an internal combustion engine in which the fuel charge is ignited by the heat of compression.
What are the 3 classifications of engine?
Types of engines and how they work
- Internal combustion engines (IC engines)
- External combustion engines (EC engines)
- Reaction engines.
What are classification of IC engine according to fuel used?
Internal-combustion engines are divided into two groups: continuous-combustion engines and intermittent-combustion engines. The continuous-combustion engine is characterized by a steady flow of fuel and oxidizer into the engine.
How do you classify IC engines explain the working of 4 stroke diesel engine?
What Are the Strokes of a 4-Cycle Engine?
- Piston moves down the cylinder bore from top dead center (TDC) to bottom dead center (BDC)
- Intake valve is open, the exhaust valve is closed.
- Downward piston motion creates a vacuum (negative air pressure) that draws that air/fuel mixture into the engine via the open intake valve.
What is the difference between SI and CI engine?
Difference Between Si engine and Ci engine
Si engine is internal combustion engine that operates on the principle of spark ignition. It uses petrol and utilizes the Otto cycle. The diesel (Ci) engine is also an internal combustion engine, which uses diesel fuel and operates on diesel cycle.
What is the difference between IC engine and EC engine?
An Internal combustion engine does not require a boiler or other components, thus it is light and compact. Whereas the external combustion engine requires a boiler and other components to transfer energy, thus it is heavy. The internal combustion engine has an efficiency of about 35-45 %.
What are the 2 types of engines?
We can broadly classify engines into two categories those are Internal Combustion Engine and External Combustion Engine.
What is the classification of ICs?
ICs can be classified on the basis of their chip size as given below: Small scale integration (SSI)—3 to 30 gates/chip. Medium scale integration (MSI)—30 to 300 gates/chip. Large scale integration (LSI)—300 to 3,000 gates/chip.
