The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today. The Aioi Works of Japan’s Diesel United, Ltd built the first engines and is where some of these pictures were taken.
It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed primarily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them.
The cylinder bore is just under 38″ and the stroke is just over 98″. Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.
| Some facts on the 14 cylinder version: | ||
| Total engine weight: | 2300 tons (The crankshaft alone weighs 300 tons.) | |
| Length: | 89 feet | |
| Height: | 44 feet | |
| Maximum power: | 108,920 hp at 102 rpm | |
| Maximum torque: | 5,608,312 lb/ft at 102rpm | |
Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.
Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.
Here’s a clip of this machine in the Holland America Line – MS Noordam’s engine room (it’s a bit long, but interesting to see):
Also here is a clip of 6 of these engine moving a giant Ferry at nearly 40 mph!

Hi, While it’s nice to see your blog about the largest engine, your page on this is filled with inaccuracies. The RTA 96 is built exclusively in Korea. The photos of engine construction you show are rather old (1998 actually), of a 10 cylinder version of the RTA 96C, taken in Korea at Hanjung.
The film clip you have of “6 engines moving a giant ferry at 40 knots” is completely mislabeled. That ship has four Wartsila Sulzer ZA40 4 stroke engines, a completely different type of engine. The speed for that ship, by the way, is 27 knots. (and the film shows the ship crawling through a harbor, not at speed!)
The other video, of the Noordam, is not labeled correctly either. The Noordam has 5 Wartsila 4 stroke “46″ type engines, nothing like the RTA96.
So how about a bit of fact checking, sir? Otherwise, carry on!

So “Superfast VII” is just an exaggeration then? I was expecting a 40000 ton speedboat hydroplaning.

To Whom It May Concern,
I am a student in mechanical engineering of Tehran Technical University, and interested
To get technical information of products and new projects of your company, specialy about the biggest engines,please

I am so not impressed. The Cadillac 16 has a 16 cylinder 1000 hp/ 1000 FPT motor that gets 20 MPG using cylinder deactivation in a car with no form of forced induction. This motor has 4 times more torque but look at the size of it. One could take 6 Cadillac 16 motors and combine them to put out similar torque numbers with better fuel economy, less weight, less size, way more Horsepower & a far quicker engine response. Or, you could alternatively use fewer motors and forced induction.
