Main Engine 4-Stroke · Main Engines (4-Stroke)
The 16H32/40V engine is a robust, 16-cylinder, 4-stroke design with a bore of 320 mm and stroke of 400 mm, specifically engineered for heavy fuel operation. Developed by HiMSEN to meet IMO Tier II standards, this engine competes directly with established European models in both propulsion and generator set applications on large vessels. Common challenges include turbocharger fouling due to carbon deposits, which require regular inspection and cleaning when high exhaust gas temperatures are detected. Ensuring proper fuel quality and distribution is crucial for maintaining optimal performance and preventing issues like cylinder liner scuffing from insufficient lubrication or contaminants. Regular checks of fuel injectors and intake/exhaust valves can help mitigate these risks.
