What are the main components of a diesel engine?

How many parts does a diesel engine have?

In broad terms, the engine can be segregated into three key parts, the head, the block and the oil sump. 1. The cylinder head is the channel through which the fuel enters the engine chamber and exhaust gases exit. Its key components are the camshafts, valves and spark plug.

Which component is not part of diesel engine?

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

What is engine and its components?

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.

What is a diesel engine made of?

Petroleum products normally used as fuel for diesel engines are distillates composed of heavy hydrocarbons, with at least 12 to 16 carbon atoms per molecule. These heavier distillates are taken from crude oil after the more volatile portions used in gasoline are removed.

What are the 3 types of engines?

Types of engines and how they work

  • Internal combustion engines (IC engines)
  • External combustion engines (EC engines)
  • Reaction engines.

What is the major component of marine diesel engine?

Crankshaft: It is the main component behind transmitting power to the propeller shaft. Camshaft: Controls and operates the main three valves (Inlet, Exhaust and Fuel Injector) within the engine— each valve produces at different speeds.

What are the main components of marine diesel engine fuel system?

The low-pressure components include the fuel tank, fuel supply pump and fuel filter. The high-pressure side components include a high pressure pump, accumulator, fuel injector and fuel injector nozzle.

What are the two types of diesel engines?

Two-stroke and four-stroke engines

As noted earlier, diesel engines are designed to operate on either the two- or four-stroke cycle.

What is 4 stroke diesel engine?

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.

How many valves does a diesel engine have?

Commonly, each cylinder can use either two (one intake and one exhaust) or four valves (two intake and two exhaust). In modern diesel engines, four-valve designs dominate and offer the following key advantages over two valve designs: Optimized mixture formation resulting from the central, vertical injector.
