Common malfunctions of internal combustion engines
When it comes to recreational or professional boating, outboard combustion engines are often faced with technical problems that can ruin an outing. These breakdowns have an impact not only on performance but also on the yachtsman's maintenance budget. With the rise of electric motors, such as the KRONOS developed by Weenav, it's worth analysing these common problems to better understand the advantages of switching to electric motors.
Common breakdowns in internal combustion engines
Internal combustion engines, particularly four-stroke engines, have a number of sensitive points. These include :
- The lubrication system, which can be a source of serious problems if the oil level is not correctly maintained or if the filter is clogged. Such neglect can lead to premature wear and even severe engine failure.
- Ignition is often affected by the condition of the spark plugs. Worn spark plugs can cause misfiring, difficulty starting or irregular engine operation.
- The fuel supply is also a frequent cause of breakdown: the presence of impurities or water in the tank can lead to clogged filters and poor combustion.
- The battery, particularly when the voltage is insufficient, can compromise starting or recharging, making the engine difficult to use.
- Finally, mechanical problems with gear shifting, often due to incorrectly adjusted cables or obstacles, can block the transmission and require manual or technical intervention.
The electric motor: simplicity and reliability
Unlike combustion engines, Weenav's KRONOS electric motor benefits from a streamlined design that eliminates many sources of failure. The absence of fuel, oil, spark plugs or filters drastically reduces the risk of malfunction linked to these elements.
What's more, the KRONOS incorporates a high-performance lithium-ion battery, guaranteeing stable range and instant start-up, without the constraints of conventional batteries. The electronic control simplifies gear shifting, making navigation smooth and seamless.
Costs and frequency of breakdowns: an estimate
According to feedback from yachting professionals, the average annual cost of repairs and maintenance to an internal combustion engine can quickly add up, reaching several thousand euros over a decade. These costs include oil changes, replacement of wearing parts, work on the ignition system and fuel-related repairs.
In comparison, the electric motor offers significantly lower maintenance costs, with simpler and less frequent servicing. The higher initial investment is offset by a significant reduction in expenditure over the long term.
In short, electric motorisation, as exemplified by the KRONOS, offers yachtsmen a reliable, economical and ecological solution, by eliminating the common breakdowns associated with combustion engines. The choice of electric power is a natural progression for calm, sustainable sailing.
