The Colt-Pielstick PA6B STC is the latest development of the PA6 engine, intended for ships requiring high-propulsion power combined with a lightweight installation. Available in 12-, 16-, 18-, and 20-cylinder configurations, the PA6B engine is designed specifically for the high demands of naval and commercial markets.
The PA6B engine features Sequential Turbo Charging (STC), which uses two turbochargers in parallel for efficient full-power operation and the use of only one turbocharger for low speed, high-torque operation. The use of one turbocharger maximizes the available energy from the whole engine instead of only half the engine, as is typically done. The extra exhaust energy (double) boosts the turbocharger away from surge conditions and delivers the necessary combustion air to allow engine operation in areas otherwise unattainable.

The concept behind the FM-MAN 27/38 won the prestigious International Seatrade Award for Innovation in 1996. With its simplified and compact design, efficiency, few parts, and low maintenance requirements, the genset and propulsion versions of the 27/38 have the ability to significantly improve the effectiveness of any aspect of ship operations and/or cargo handling.
All support functions %u2014 oil and water pumps, coolers, filters, and safety and regulator valves %u2014 are housed in a single front-end box for easy access and maintenance. The engine is lower and shorter than the other longstroke engines in its power class. It can be installed in restricted engine room areas. The L27/38 is designed for 20,000 to 25,000 service hours between overhauls, and requires only minimal maintenance. Each complete cylinder assembly can be removed as a unit for maintenance or replacement, without requiring a large overhaul height. The L27/38 meets IMO NOx emission limits. Its automatic lube oil filter eliminates the disposal problems associated with conventional paper filter elements.

With over 840 engines in operation, the Colt-Pielstick PA6 is respected worldwide for its reliability and its incredibly advanced technology. This engine has been expanded to include the longstroke %u201CB%u201D version, which is 25 percent more powerful than the PA6. The PA6B has a redesigned connecting rod, crankshaft, cylinder head, and liner with an anti-bore polishing ring. In addition to excellent fuel consumption, the PA6B engine already meets the EPA's stringent Tier II emissions standards going into effect in 2007.
All feed pumps (fresh water, lube oil, and fuel oil) are driven by the engine. The lubricating circuit including the oil filter is fully integrated into the engine. This results in increased reliability, safety, and simplified installation. The PA6B engine incorporates an integrated combination plate heat exchanger (Combi-Cooler) for cooling both lube oil and the water cooling loop.

RT-Flex - Intelligent engines
Silniki
These engines are equipped with high pressure rails of fuel and oil (common rail) and electronic control.
The designed rails offer new options as far as the engine design and operation are concerned, among the others they:
1. Simplified mechanical subassemblies of the engine.
2. Introduced flexibility of injection and valves operation.
3. Increased movement dependability of the engine due to the use of the double engine safety system.
4. Gave higher efficiency in comparison to traditional engines.
5. Introduced many options of reducing exhaust gas emission.
In the engines of "flex" type the designers resigned from such generally used so far designing schemes like:
1. Fuel pumps of SULZER construction - one big pump for one cylinder.
2. Overload valves (forward - backward).
3. Distribution shaft.
4. Overload actuator.
5. Distribution shaft drive (three or four gear wheels of ~1500 mm diameter).
Rejecting the above subassemblies allowed to introduce innovative designing solutions, e.g.:
1. Injection pumps of Bosch type - for example for 7-cylinder engine there are just three small pumps generating fuel pressure for the rail.
2. The fuel rail - capable of keeping fuel pressure of ~1000 bar.
3. Injection control assembly - small hydraulic device enabling precise control of the injection parameters.
4. Oil rail - powered with two small piston pumps (for 7-cylinder engine), in which the pressure of ~200 bar is maintained.

Electronically controlled ME/ME-C engines
Characteristics:
-reduced fuel consumption,
- better cylinder compensation,
- better acceleration,
Detailed observation and diagnostics of ME series engines also revealed:
- easier service,
- longer intervals between overhauls,
- easier gain of mean indicated pressure (MIP).
The operators of engines also indicated lower fluctuations in engine revolutions during stormy weather compared to fluctuations in engines with fuel injection controlled by distribution shaft. The fuel savings of the order of 4% were indicated in comparison to engines without electronic control.
Detailed specification:
The essence of the engines from this group is based on automatic and hydraulic system of fuel injection activation and on the control of exhaust valves. The activating devices are electronically controlled here, through determined number of controlling systems forming "Engine Control System".
Fuel injection in the engines of ME series is improved by supporting pressure device (Buster), which mechanically is a simpler device compared to fuel pumps used in traditional engines of MC series. The fuel plunger in engines of ME series is driven by piston activated by electronically controlled, hydraulically dosing oil valve, which is also the source of fuel in this case. Also the exhaust valve is, in engines of ME series, hydraulically opened, and closed by pneumatic shockabsorber.
