Thats pretty wild. Wonder why the butterflies don't sync up with the rpm.

Thats pretty wild. Wonder why the butterflies don't sync up with the rpm. Well, Scott, this is a Diesel. Conventional diesel engines have inherently no throttle, because of the different type of mixture preparation. The power output of a diesel engine is controlled by regulating the quantity of fuel that is injected into the cylinder. Because the engines do not need to control air volumes, they lack a butterfly valve in the intake tract. In order to still be able to use a vacuum brake booster, a vacuum pump must be used. Modern diesel engines have a throttle again, this however, is only to reduce the shaking when you turn off the engine. In operation, the butterflies are always open. This "throttle" is referred to as intake manifold. An exception to this generalization is newer diesel engines meeting stricter emissions standards, where a throttle is used to generate intake manifold vacuum, thereby allowing the introduction of exhaust gas to lower combustion temperatures and thereby minimize NOx production. |

The engine is 10 feet long, 46 inches wide, and 57 inches tall without the blowers, and with the Allison transmission, the whole thing weighs 9,800 pounds. If you’re into the metric system, the displacement is 27.9 liters. So what do you do with an engine this size? Well, you put it in a custom built show semi of course and that’s exactly what Mike Harrah did. The engine is now matted to an Allison transmission inside a custom 359 Peterbilt truck with a massive 40-foot long custom chassis to hold it all together. What do you think the turning radius of that is? speednik.com/files/2012/08/v24_diesel_2.jpg |

Bobby it is an amazing engine. I found the video surfing around one day and have watched it many times since. I posted the pic of the truck for you.  |
