Put a fart cannon on it for a little more hp and it would increase style too!

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.


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 it's most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.



Installing the "thin-shell" bearings. Crank & rod journals are 38" in diameter and 16" wide:


The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version.
Note the steps by each crank throw that lead down into the crankcase:


A piston & piston rod assembly. The piston is at the top. The large square plate at the bottom is where the whole assembly attaches to the crosshead:


Some pistons:


And some piston rods:


The cylinder deck (10 cylinder version). Cylinder liners are die-cast ductile cast iron. Look at the size of those head studs!:


The first completed 12 cylinder engine:

I bet it requires a pretty big wrench to assemble it.

I bet it requires a pretty big "set" to design it.

I think it's got a number 2 rod knock let's shut it down and walk into the crankcase and have a look:) That's the size of the engine I want to work on:)

In my neighborhood the standard is F-350 with powerstroke deisel and I've had it with with the cattle guard, giant tires, clank-clank-clank deisel pickup trucks. I'm going to fight back.
Has anyone seen a conversion kit for a subaru forester?
How much does one of these engines cost?

I've seen the kit. it looks a lil wierd. mostly involves MUCH bigger wheels and tires, and a bunch of mirrors so you can see around the 3 story engine in front of you. but other than that it bolts right up. I'm pretty sure these engines are only about $100,000.00 or more. not too shabby.

I don't think you will have any problems bolting a Subaru to that engine all though I don't know why you would want to put a subaru on that engine:)
