New product
The Cylinder Head is one of the most important components of a marine diesel engine. It forms the upper section of the combustion chamber and houses critical engine components such as fuel injectors, exhaust valves, starting air valves, indicator cocks, safety valves, and cooling passages.
Whether installed on a MAN B&W low-speed propulsion engine, a Sulzer RT-flex engine, a Wärtsilä auxiliary engine, or a Hyundai Himsen generator engine, the cylinder head plays a direct role in combustion efficiency, fuel economy, engine reliability, and vessel safety.
Marine engine cylinder heads operate under extremely high temperatures and pressures. Proper maintenance, periodic inspection, hydraulic testing, crack detection, and overhaul are essential to ensure safe and efficient engine operation.
SM MARINE SERVICE™ supplies complete cylinder heads, cylinder covers, and cylinder head spare parts for all major marine engine brands worldwide.
MAN B&W engines are among the most widely used marine propulsion engines in the world. Models such as S35MC, S42MC, S50MC-C, S60MC-C, S70MC-C, K80MC-C and K90MC use heavy-duty cylinder heads designed to withstand continuous high-pressure combustion cycles.
The MAN B&W cylinder head contains the fuel injector assembly, exhaust valve arrangement, starting air valve, indicator cock, and cooling water passages. These components must be regularly inspected during engine overhauls to maintain engine performance and prevent unexpected failures.
SM MARINE SERVICE™ supports the supply of complete MAN B&W cylinder heads, exhaust valve seats, injector sleeves, valve cages, cylinder head studs, and overhaul kits.
Sulzer RTA and RT-flex engines continue to power thousands of vessels worldwide. Popular models include RTA48, RTA58, RTA68, RT-flex50, RT-flex58T and RT-flex68D.
Sulzer cylinder heads are engineered for long service life and feature advanced cooling arrangements to manage combustion temperatures efficiently. During major overhauls, ship operators frequently replace valve seats, injector sleeves, gaskets, and cooling components.
SM MARINE SERVICE™ supplies replacement and reconditioned Sulzer cylinder heads and spare parts for various Sulzer engine models.
Wärtsilä engines are widely used as both main propulsion engines and auxiliary generator engines. Common models include Wärtsilä 20, Wärtsilä 26, Wärtsilä 32, Wärtsilä 38, and Wärtsilä 46.
Wärtsilä cylinder heads are designed to provide efficient combustion, excellent cooling performance, and long operational life. Regular maintenance includes pressure testing, injector seat inspection, valve seat machining, and cooling passage cleaning.
SM MARINE SERVICE™ provides sourcing support for complete Wärtsilä cylinder heads and associated spare parts.
Hyundai Himsen engines have become increasingly popular onboard merchant vessels and offshore platforms. Models such as H17, H21, H25 and H32 utilize advanced cylinder head designs optimized for fuel efficiency and operational reliability.
Cylinder heads used in Himsen engines require regular inspection of injector sleeves, exhaust valve seats, and cooling systems during scheduled maintenance.
SM MARINE SERVICE™ supports Hyundai Himsen cylinder head spare parts and overhaul services worldwide.
Daihatsu marine engines are widely used as auxiliary engines onboard cargo vessels, tankers, and offshore vessels. Cylinder heads used in DK and DC series engines are known for their durability and ease of maintenance.
Routine maintenance includes valve seat inspection, fuel injector sleeve replacement, cooling channel cleaning, and hydraulic pressure testing.
SM MARINE SERVICE™ supplies Daihatsu cylinder heads, overhaul kits, and replacement spare parts for various engine models.
Marine engines from Yanmar, MAK, Bergen, Niigata, Akasaka, Mitsubishi and Kawasaki continue to operate onboard vessels throughout the world. These engines require periodic cylinder head maintenance to ensure combustion efficiency and long-term reliability.
