What is the working principle of 4-stroke diesel engine?
The four stroke diesel engine works on principle of diesel cycle in which the fuel is ignite by increasing the temperature of the air above the self-ignition temperature of fuel.
What is the working of 4 stroke engine?
A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.
What are the applications of 4-stroke diesel?
The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes (many motorbikes use a two stroke engine).
What are the parts of a 4-stroke diesel 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.
How does a diesel engine works?
In a compression-ignited system, the diesel fuel is injected into the combustion chamber of the engine and ignited by the high temperatures achieved when the gas is compressed by the engine piston.
What is the working principle of engine?
A heat engine is a machine, which converts heat energy into mechanical energy. The combustion of fuel such as coal, petrol, diesel generates heat. This heat is supplied to a working substance at high temperature. By the expansion of this substance in suitable machines, heat energy is converted into useful work.
What are the advantages of 4-stroke engine?
More fuel efficiency :- 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes. Less pollution :- As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.
Where are 4-stroke engines used?
What is the main parts of diesel engine?
A medium or high speed diesel engine has such components and parts as engine body, crankshaft, connecting rod, piston, cylinder liner, heat exchanger, cylinder cover, high-pressure fuel pipe and alarm, connecting rod bolt, supercharger, fuel injection pump assembly.
What cycle does a diesel engine work?
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 are the five functions of a 4-stroke engine?
Every reciprocating internal combustion engine operates through a “cycle” of five functions: intake, compression, ignition, combustion and exhaust.
What are the parts of the four-stroke cycle?
A four-stroke engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle.
