Fuel consumption at sea

Posted on 9 May 2011 | 3 Comments

As we continue to develop the Scuderi Engine, it is typically looked at as primarily an automotive engine. True, our development path has been very vehicle-centric. (The company chose this development strategy early on, mostly because the automobile is one of the most complex and difficult environments to create consistent combustion.) 

The Wärtsilä-Sulzer RTA96-C, the world's largest engine that powers the Emma Maersk, a 1,300-foot- container ship.

However, that hasn't stopped other industry sectors from noticing our revolutionary thermodynamic process and the benefits it brings. The marine sector is one such industry.

The global shipping industry is struggling to find ways to address three major needs – lowering fuel consumption, reducing N0x, and reducing soot. Like everywhere else, the big one is fuel consumption.  Ask any day sailor on a recreational boat and they’ll grumble about the cost of filling the tank just to get the family out on the water for a few hours.

But then take a typical Northeast U.S. whale watch boat. The captain will tell you they burn about 80 gallons of fuel an hour. So in a 10-hour day of going roughly 22 miles per hour (at ¾ speed), they’re going to burn over 800 gallons of fuel. If they go full speed (about 30+ miles per hour), even more fuel is consumed.  

Scale that up to the big ships, and you get more of a head-spinning situation. The largest diesel engine in the world, the Wärtsilä-Sulzer RTA96-C, burns about 16 tons of fuel per hour. Yes, that’s tons per hour… 

So the need for a better solution is obvious. And that’s where the Scuderi Engine comes in. The Scuderi design can be adapted for various internal combustion engine applications, including marine craft. The revolutionary “Firing After Top Dead Center” and the unique cylinder configuration results in an extremely robust and efficient combustion process. Further, because the engine burns fuel at lower peak temperatures than a conventional engine, it doesn’t create the NOx that regulators and OEMs are working so hard to reduce. So we’re looking at potentially lowering emissions by up to 80 percent while reducing the rate of fuel consumption to historic levels.

And that’s something anyone behind the wheel – no matter what you’re driving – can look forward to.

  • It is better to find more alternative source of energy than letting all died out. Revolution around these processes will be a much more outstanding.

  • Will the Scuderi engine work as a compression engine or ignition only? I don't see gasoline being used in large marine applications.. way too volatile. To the previous poster's point, a lot of the sulfer emissions problems with ships is because they burn the cheapest, less refined, bottom of the barrel fuel. Biofuels would help there but of course are more expensive.

  • There's also the SECA (Sulfur Emission Control Area) issue, where ships in and around harbors are under increasingly stringent emission control regulations. A cleaner burning diesel engine would be of immense benefit here too.
