meant to include some facts... 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 more 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.
Wow... there are even ladders that go down into the crank case! I wonder how much a timing belt change is on this puppy...
I got those engine pix in an email forwarded to me. All I have to ask is "can it spin 8,000 rpms like my Ferrari?" (My guess is that at 2500 RPMS that thing would explode like a bomb)
Hmmmm.... I thing that might require just a LITTLE modification to the rear hatch cover on my 328. LOL Try fitting that baby in your garage when you're done with the install. Maximum power: 108,920 hp at 102 rpm Maximum torque: 5,608,312 lb/ft at 102rpm I have just one thing to say -- OMG!!!! 5 MILLION lb/ft of torque!!??!! At 102 rpm! Are you kidding me? Supertanker engine, or I guess you call that a power plant, for sure. No wonder it takes a couple of miles to stop one of those things. Wow! Thanks for sharing that.
These engines are amazing, insofar that they make them float... 2-stroke turbocharged diesel, makes a lot of sense. Knowing very little about American truck-engines, but isn't the Detroit V12 also 2-stroke and supercharged + turbocharged?
I know little about diesel engines, I just figured in these days when 2 stroke lawnmowers and outboard boat motors are being phased out and new ones outlawed, I got a chuckle. However I could imagine that a four stroke that big would be an even more monumental task.
It's not just a monumental task, it's also that 2-stroke engines have very good efficiency. Speaking pollution, small 2-stroke engines are small environmental disasters, but big ones such as this are setup very differently and are not as bad because they do not burn their lubrication. I doubt going four stroke would have environmental benefits in that sense. Also, who monitors air quality over the oceans? On another note, I always found it interesting and a bit tragic that most of the sulfur that is taken out of the petrol sold at gas stations today (to prevent acid rain and the like) is supposedly finding its way into the bunker oil for these ships.
I think your vehicle acceleration will be pretty poor === 42lb/hp and that's JUST the engine-- not counting the car and fuel tank/fuel with the 14cyl engine. And what if you miss a shift and over rev it to 103 RPM???
I put one of those in my '59 Ford pickup....works great...frontal view is obstructed a little, so I installed a camera system for safer driving.
Too bad Mark E is not on the site - he would love to take on the project and shove it into his 308 - just as soon as he gets the V12 running.
Hello. New here but I saw this thread and had to comment. I worked in a Power generation station with engines like these. The engines we had started with compressed air injected into each cylinder timed to make the engine rotate, then light it off with diesel, and then run on natural gas. Better wear hearing protection. It was always thrilling to hear these things start up! Bill
