Marine Diesel Engine Maintenance

Marine Diesel Engine Maintenance

In a conventional marine diesel engine the ability is produced by scorching compressed air igniting fuel sprayed below very high pressure into the cylinder head. A marine diesel engine doesn't use a carburetor to combine fuel and air or spark plugs to ignite the mixture. Instead it employs the pistons to compress the air to 3000 kPa which causes it to grow to be extremely hot and the fuel is ignited as quickly as it's injected into the cylinder.

Some marine diesel engines are fitted with a heater plug within the inlet manifold or a glow plug in the pre-combustion chamber of each cylinder to supply additional heat to the combustion air during starting.

Diesel engines are heavier and slower revving than petrol engines but they are additionally more reliable because they don't rely on external carburetion or an electrical spark for ignition.

Newer engines use an electronic fuel injection system whereby fuel and air are combined more completely within the pre-combustion chamber before entering the cylinder. This method maximizes power and fuel economy and is also less polluting.

Each boater ought to have an understanding of how their engine works so let's start by explaining the mechanical cycles.

Most reciprocating piston inside combustion engines work on certainly one of two mechanical cycles-either the four-stroke cycle or the 2-stroke cycle. These cycles designate, in correct sequence, the mechanical actions by which the fuel and air gain access to the engine cylinder, the gas pressure - resulting from combustion - is converted to power and, lastly, the burnt fuel is expelled from the engine cylinder.

The Fundamental 4-Stroke Diesel Engine

From its name, it is obvious there are 4 strokes in one complete engine cycle. A stroke is the movement of the piston by means of the full length of the cylinder and - since one such movement causes the crankshaft to rotate half a turn - it follows that there are crankshaft revolutions in one full engine cycle.

The four strokes within the order they occur are:

1. Inlet stroke. With the inlet valve open and the exhaust valve closed, the piston moves from high dead heart (TDC) to bottom dead center (BDC), creating a low-pressure space in the cylinder. Clean, filtered air rushes by way of the open inlet valve to alleviate this low-pressure area, and the cylinder fills with air.

2. Compression stroke. With both valves closed, the piston moves from BDC to TDC, compressing the air. During this stroke the air turns into heated to a temperature sufficiently high to ignite the fuel.

3. Power stroke. At roughly TDC, the fuel is injected, or sprayed, into the new, compressed air, where it ignites, burns and expands. Both valves stay closed, and the pressure acts on the piston crown, forcing it down the cylinder from TDC to BDC.

4. Exhaust stroke. At approximately BDC the exhaust valve opens and the piston begins to maneuver from BDC to TDC, driving the burnt fuel out of the cylinder by way of the open exhaust valve.

The Two-Stroke Diesel Engine

The two-stroke engine makes use of two piston strokes to finish one energy stroke and, subsequently, fire twice as usually as a 4-stroke engine. A -stroke engine is smaller and less complicated with fewer shifting parts. A -stroke engine has the potential to produce twice as a lot energy as a four-stroke engine of the same size, nonetheless, because of the extra fitting required in a two-stroke diesel engine, for example blowers and governors, they grow to be more expensive to produce. There was a shift towards four stroke diesel engines which have become more environment friendly and smaller.

Defend Your Marine Diesel Engine

Protect your engine by avoiding long intervals (more than 10 minutes) of idling in a "no-load" situation. That is typically executed to cost batteries or cool refrigeration but if achieved repeatedly it can glaze the bores of the engine and cause untimely engine failure. If the vessel is in a berth the engine may be put in gear to create load at idle.

All boat fuel injector cleaning owners ought to have an understanding of basic marine diesel engine maintenance to keep themselves and their households secure on the water.
