8 Main Parts Of Diesel Engine And Their Function.
What are the main parts of a 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.
How many parts does a engine have?
To withstand its heavy workload, the engine must be a robust structure. It consists of two basic parts: the lower, heavier section is the cylinder block, a casing for the engine’s main moving parts; the detachable upper cover is the cylinder head .
Which component is not used in diesel engine?
The diesel internal combustion engine differs from the gasoline powered Otto cycle by using highly compressed hot air to ignite the fuel rather than using a spark plug (compression ignition rather than spark ignition). In the diesel engine, only air is initially introduced into the combustion chamber.
How many parts does a modern car engine have?
What are the 3 main engine systems?
- Mechanical fuel injection systems.
- Operating systems.
- Piston rings.
- Primary system.
- Spark ignition systems.
- Spring retainers.
What are the advantages of diesel engines?
Pros of Diesel Engines
- Excellent gas mileage.
- Longer range. Better fuel economy means you don’t have to hit the gas station as often. …
- Diesels have no spark plugs or distributors, so they never need ignition tune-ups.
- Better durability. …
- More torque.
What parts are attached to the engine front end?
The engine is constructed from different parts. These parts are: bottom end, top end, front end, oil pan, valve cover, and front cover. Bottom End (short block): The bottom end includes the cylinder block with all of its internal parts installed. The pistons, rods, crankshaft, and bearing would be in the block.
What is the most important part of a car engine?

What is inside a car engine?
Specifically, an internal-combustion engine is a heat engine in that it converts energy from the heat of burning gasoline into mechanical work, or torque. That torque is applied to the wheels to make the car move. … Engines have pistons that move up and down inside metal tubes called cylinders.
What is the four stroke diesel engine?
The medium speed four-stroke engine (250 – 1200 rev/min) is used for the auxiliaries such as alternators and also for main propulsion with a gearbox. A four-stroke diesel engine resembles a gasoline engine as it works on the four-stroke cycle, that is: admission, compression, power and exhaust.
How does diesel engine start?
Injected fuel is ignited by its reaction to compressed hot air in the cylinder, a more efficient process than that of the spark-ignition internal-combustion engine. … The diesel engine gains its energy by burning fuel injected or sprayed into the compressed, hot air charge within the cylinder.
What if petrol is used in diesel engine?
Putting petrol in a diesel car can cause serious damage to the fuel injection system and the engine. … Serious engine damage may also occur due to detonation caused by uncontrolled petrol ignition under the much higher compression ratio in diesel engines.
What are the main parts of a engine?
What are the main parts of an engine?
- Engine block. The block is the main part of the engine. …
- Pistons. Pistons pump up and down as the spark plugs fire and the pistons compress the air/fuel mix. …
- Cylinder head. The cylinder head is attached to the top of the block in order to seal the area to prevent the loss of gases. …
- Crankshaft. …
- Camshaft. …
- Valves. …
- Oil pan.
What is the main component of engine?
For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
