Marine Rebuild Kits

Ship captains and operators should understand diesel engines fully before using marine rebuild kits. The process of assembling engine parts into a functioning engine is impossible without knowing each step of engine operation. Most marine diesels utilize four-stroke motions to generate power and expel exhaust.

The four-stroke diesel engine used by marine companies involves four cycles that are critical to smooth acceleration. The following cycles allow diesel engines to take advantage of the potential efficiency of diesel fuel:

• Intake
• Compression
• Combustion
• Exhaust

Using Marine Rebuild Kits to Improve Engine Cycles

The intake stroke of a marine diesel engine begins with the opening of the intake valve. The air that enters the cylinder decreases pressure and knocks the piston down before advancing to the compression stage. Compression occurs when the piston rebounds from the bottom of the cylinder and applies pressure to the air gathered near the cylinder head.

The second half of four-stroke engine operation is critical for marine mechanics to understand. One reason companies purchase rebuild kits is the failure of fuel injectors during the combustion process. Combustion involves the piston hitting the top of the cylinder, an injection of fuel at the piston's peak and an ignition of diesel that causes the piston to fall to the bottom.

Another reason for marine rebuild projects is an accumulation of waste within the engine that causes sluggish movement. The exhaust stroke in diesel engines is designed to use the piston's final movement upward to push waste into the exhaust valve that connects to the exhaust manifold.

Marine companies can purchase engine-rebuild kits and parts through Internet Diesel. These kits can be shipped for free to the lower 48 states, along with two-year manufacturer warranties.
