Produced by the ignition of a very high pressure high temperature compressed air injected fuel to power a cylinder head of a conventional diesel engine for ships. Marine diesel engines do not use spark plug or carburetor to mix the fuel and air to ignite. Instead, when the fuel is injected into the cylinder as soon become very hot and using a piston compresses ignition 3000 kPa air oven.
Some marine diesel engine equipped with a spark plug of the pre-combustion chamber of each cylinder to provide additional heat to the combustion air to the heater connector to the top or to the intake manifold.
A diesel engine are more reliable due to the heavy and slow to raise rates than petrol engines, but also does not rely on external exhaust or electrical ignition spark.
Recent engine using electronic fuel injection system by more sufficiently mixed in the pre-combustion chamber before the fuel inlet and the air cylinder. The system maximizes power and fuel economy, and also a less pollution.
Each boat must have an understanding of how it works Let's start by explaining the machine cycle engines so.
Most of the reciprocating piston internal combustion engine having two mechanical cycles operating at any one of the four-stroke cycle or two-stroke cycle. In this cycle, the correct sequence, designated, the mechanical energy is a fuel gas pressure and increasing access of air in the engine cylinder, said combustion-converted into electric power, in the end, the combustion gas discharged from the cylinders motor.
Basic four-stroke diesel engines
From the name, it is obvious that the full four-stroke cycle engine. This movement causes a crankshaft to rotate a half turn so-stroke is a movement of the piston along the length of the cylinder that the two rotations of the crankshaft in a complete engine cycle.
Four lines, According to the Order of Appearance are:
1. Access the stroke. And the opening of the intake valve and the exhaust valve closed, and the piston moves from the top dead center (TDC) the cylinder creating a low pressure region of bottom dead center (BDC). Clean, filtered air rushes in from the intake valve open to relieve the depression, fills the air cylinder.
2. Compression stroke. With both valves closed, the piston is driven by compressed air, BDC to TDC. Heated to a temperature sufficient to ignite the air-fuel during the route.
3. The power line. About TDC, the fuel is ignited and burns the high temperature expansion, injected or sprayed into the compressed air. Both valves are closed and the pressure acting on the piston crown at TDC to force the cylinder down in the CNS.
4. Export route. About BDC begins to drive the combustion gases from the cylinder through the exhaust valve open exhaust valve opens and the piston, BDC moved to TDC.
Two-Stroke Diesel Engines
Stroke engines often use the two piston strokes episodes to complete the four-stroke engine boat fire, so a power stroke episode. Two-stroke engines are small and simple, less moving parts. Stroke engine because of this, for example, for the fan and the governor, two-stroke diesel accessories, however, are able to produce a power of two-stroke engine of the same times the size that will be more cost needed for machine. Most effective was a four-stroke diesel engine that is smaller starting to change.
Protect Your Marine Diesel Engine
By preventing children for a long time (over 10 minutes) of the conditions "no load" for engine protection. This is often the case; the engine will only be repeated for charging batteries or cool naenggakreul glaze hole and cause premature engine failure. When the ship is moored, the motor can be mounted on the device to make the inertia of the load.
