Power units designed for the operation of sea and river vessels have a colossal margin of safety. They are not so easy to disable, as they work with smooth loads. But, even in this case, timely diagnostics and repair of diesel engines greatly reduces crashes. When the engine suddenly stops and the boat loses speed.
Prevention as a recommendation of experts
Professional mechanics know that regular inspection of a diesel engine allows you to notice a malfunction at an early stage. Prevention, or timely technical inspections, is just as important as refueling the engine with high-quality diesel fuel. Ignoring leads to a sudden stop and the following negative consequences:
- Incorrect timing adjustment.
- The pump responsible for the fuel supply has been damaged.
- Electrical or mechanical failure of the engine starter.
- Overheating and seizure of pistons or crankshaft.
- Premature gear wear.
A sudden stop of the engine can be avoided. It is enough to regularly carry out scheduled diagnostics and technical inspections. Use quality and recommended consumables for this engine. Do not allow the crankshaft to rotate in the red zone of unacceptable speed.
Indirect diagnostics by exhaust gas color
Experienced mechanics can predict diesel engine breakdowns in advance with great accuracy. For this purpose, they focus not only on the sound of the engine, but also on the color of the exhaust gases that escape from the pipe. Color change is associated with the following typical problems:
- damaged or worn camshaft cams;
- sticking of one or more valves;
- too early or too late injection of fuel into the cylinders;
- valve seat damage or burnout;
- Incorrect adjustment of the gas distribution mechanism.
Only a specialist can accurately answer what happened to the motor. And in order to completely restore it, you will need repair and maintenance of diesel engines. Replacement of damaged and worn parts. Fine tuning and adjustment. Only after an integrated approach can it be guaranteed that the engine will return to all its original technical and operational characteristics. The economic indicator will improve without reducing the power of the power unit.
