How many processes are there to execute a Diesel cycle?

In an ideal Diesel cycle, the system executing the cycle undergoes a series of four processes: two isentropic (reversible adiabatic) processes alternated with one isochoric process and one isobaric process.

What is a 4 cycle diesel engine?

Diesel engines may be designed as either two stroke or four stroke cycles. The four stroke Diesel engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.

What are the four phases of the combustion cycle?

The cycle includes four distinct processes: intake, compression, combustion and power stroke, and exhaust. Spark ignition gasoline and compression ignition diesel engines differ in how they supply and ignite the fuel.

What is the 4 1 process in Otto cycle?

The four-stroke Otto cycle is made up of the following four internally reversible processes: 1–2, isentropic compression; 2–3, constant-volume heat addition; 3–4, isentropic expansion; and 4–1, constant-volume heat rejection.

Which of the following process is one of the process in a Diesel cycle?

Explanation: Diesel cycle consist of one isobaric process, one isochoric process and two adiabatic process. Heat rejection process is isobaric process.

What are the parts of 4 stroke engine?

Parts of a Four Stroke Engine

• Piston. In an engine, a piston transfers the expanding forces of gas to mechanical rotation of the crankshaft through a connecting rod.
• Crankshaft.
• Connecting Rod.
• Flywheel.
• Inlet and Outlet Valves.
• Spark Plug.
• Suction/Intake Stroke.
• Compression Stroke.

Which of the following stages is the last stage of the combustion process in diesel engine?

Practically, the burning of the fuel in the combustion chamber remains to continue during the expansion stroke. The main reason behind it is the reassociation of dissociated gases and unburnt fuel. Therefore, this last phase of combustion is called After Burning.

What is Otto and Diesel cycle?

Both these cycle are air standard cycles of automobile engines. Otto cycle is used for petrol or spark ignition engine while diesel cycle is used for diesel or compression ignition engine….Diesel cycle vs Otto Cycle:

What is the difference between Otto and Diesel cycle?

The Otto cycle has less compression ratio (7:1 to 10:1) but in diesel cycle the compression ratio is high (11:1 to 22:1). In Otto cycle as well as in diesel cycle heat rejection takes place at constant volume. The efficiency of Otto cycle is less as compared with the Diesel cycle.
