Modeling the "Fargo Area Rapid Transit" in O scale 3 rail.
QUOTE: Originally posted by Boyd The Minnesota Zephyr goes behind the house I live in. Sunday it started several fires along the tracks that I helped put out. This isn't that uncommon of an occurance in the dry parts of the summer. People working for a track contractor said the sparks were coming from the exhaust. Can a spark arrestor be installed on the exhaust. I like to see the train go behind the house I'm in, but I don't want a fire to burn up the house.

QUOTE: Originally posted by Leon Silverman Randy: The blower on a Diesel has exactly the same purpose as it does on a gasoline engine. The only difference is that it is more effective on a diesel due to the relatively slow motion of the engine (1000 vs 6 to 8,000 rpm). Headers on a gasoline engine can greatly increase the horsepower output , but only on a racetrack where the noise poses no problem. A supercharger is the only way you can increase the power of a diesel without generating objectionable noise levels and also avoiding operating at higher rpms. An automobile engine can operate at higher rpms to develop more horsepower because the reciprocating components are relatively light. The High compression ratios of diesels dictate that all components be heavy and thus unable to operate at higher rpms to generate more horsepower. The supercharger enables the diesel engine to develop more power because it forces more air into the cylinders. It has the same effect on gas engines. The only difference is that there are other ways that you can soup up a gasoline without resorting to supercharging.

QUOTE: Originally posted by adrianspeeder No, sorry but thats not right. The supercharger on a 2stroke emd is there for exhaust scavenging and I think only makes 1-2lbs of boost. Compleatly different animal than a gasser. Turbos are on diesel are used waaaay more often than superchargers for boosting purposes. (I know, I have one...) In fact, I cant think of a diesel engine right now that doesn't use a turbo and uses a supercharger instead. RPMs are lots less on a diesel engine vs. a gasser, as there is no need for rpms for power. Heck, I make more torque at idle in my PSD than my ole 302 does at top it its torque curve. And the peak of the torque curve is around only 1300rpm for me on the diesel. There are lots of ways to hop up a diesel engine other than making boost. Nitrous, Propane Injection, computer tuners for newer engines, or mech fuel adjustments for old school diesels. Your thoughts please.... Adrianspeeder
QUOTE: Originally posted by M636C There are mufflers for EMD engines which contain more effective baffles. These were fitted to EMD units in New South Wales in 1980 after a dry summer and complaints from farmers. Ours were made by Farr, I think. All EMD blower engines have cylindrical mufflers immediately above the engine. The modified versions looked the same but had different internal baffles that were more effective as spark arrestors. They also reduced the sharp exhaust beat of the EMD locomotives, sadly. The new mufflers had differently spaced stacks, so you could always tell which units were modified. Peter
