Identifying the Engine Problems Caused by CNSL
As the maritime industry explores alternative fuels, one particular blend has raised significant concerns: cashew nutshell liquid (CNSL). Reports from CTI-Maritec indicate that CNSL is linked to severe engine issues. Understanding these problems is crucial for shipowners aiming to maintain their vessels effectively.
1. Fuel Sludging and Injector Failures
Fuel sludging is a major issue that has emerged with the use of CNSL. This phenomenon occurs when the fuel thickens and forms a gel-like substance. It can block fuel lines and disrupt the flow of fuel to the engine. The result? Injector failures. In fact, reported cases of injector failure have increased by 35% since CNSL's introduction in very low sulphur fuel oil (VLSFO).
Why is this happening? The high potassium content in CNSL contributes to these injector failures. Potassium creates post-combustion deposits that can clog injectors, leading to inefficient fuel combustion. This not only affects engine performance but can also lead to costly repairs.
2. Clogging Filters and System Deposits
Another significant problem associated with CNSL is the clogging of filters. As the fuel sludges, it can create deposits that accumulate in fuel filters. This can lead to reduced fuel flow, causing the engine to operate inefficiently. Shipowners must regularly check and replace filters to mitigate this issue.
- Clogged filters can lead to:
- Increased maintenance costs
- Reduced engine performance
- Potential engine shutdowns
Additionally, system deposits can form throughout the fuel system, further complicating maintenance efforts. Regular inspections and cleaning are essential to prevent these issues from escalating.
3. Corrosion of Turbocharger Nozzle Rings
Corrosion is another critical concern linked to CNSL. The high acid values in CNSL make it highly corrosive. This is particularly problematic for turbocharger nozzle rings, which are essential for engine efficiency. Corrosion can lead to premature wear and tear, necessitating costly replacements.
Shipowners in Singapore and Rotterdam have reported multiple operational problems linked to CNSL blends. The corrosive nature of CNSL fuels can lead to significant downtime and repair costs. Understanding the risks associated with CNSL is vital for effective maintenance strategies.
Understanding the Impact
Addressing these engine problems caused by alternative fuels is a major challenge for shipowners today. The shift to renewable fuels like CNSL is driven by environmental regulations and the need for sustainable practices. However, the unintended consequences on engine performance cannot be overlooked.
By recognizing the specific issues associated with CNSL, shipowners can develop targeted maintenance strategies. This may include:
