  • when u switch to diesel what happens to the carb and its butterfly/ throttle and the petrol in float chamber?

    do u run carb dry then restart on diesel and jam throttle open?

    how come it doesnt detonate when on petrol with the high compression ratio?

  • @tpvalley There is a compression release system that opens up a sub-chamber in the heads to effectively decrease compression, and it also turns on the ignition system when you pull the lever. When it warms up, open the diesel throttle and shove the compression lever in. The gas (petrol) system is shut off and she takes off and runs on diesel.

  • Thank-you for your video: it is certainly a very interesting little locomotive. Was it actually constructed by IH, or was it produced by a specialist manufacturer (Plymouth, Vulcan, Whitcomb or whoever)?

  • It was built by the Brookville Locomotive Works in Brookville, PA. Brookville used a lot of different IH engines in their locomotives.

  • You can see it's an IH engine, it has that distinctive "Letter Series" grille.

    Same engine as the early TD-18 crawler.

    Interesting looking unit, thanks for submitting this video.

  • 2 Stroke bike motor. ( suck and puff ) It doesn't know if it's turning clockwise or counterclock. just when to fire BFTDC or After. Thats why it will start but not rev up.

  • I dont understand how anything would run backwards... There is no fuel being injected in through the exhaust.

  • Detroit

    Back when I was a kid I rode dirt bikes. I had a 2 stroke Kaw start backwards while hill climbing. It ran but didn't rev up bacause of spark timing.

  • I don't see how an auto or aero type engine could run backwards without changing the direction of air flow through the engine. When a 2-cycle Detroit Diesel accidentally starts in reverse, it sucks it's intake air through the exhaust, and exhausts through the air cleaner. They run poorly this way for obvious reasons, but also because port and cam timing would be wrong. Big container ship engines are started in reverse to back the ship up, so some engines must be designed for this. How?

  • No, the piston goes always up and down, the only difference is that the crankshaft turns in the opposite direction

  • Cute little yard goat!

  • ...Which sucks air through it's exhaust and blows smoke out the air cleaner!
