Re: Running a Diesel with no load and no water

With a diesel the temp is more directly proportional to the load, quite logical. It's more difficult to explain why on a spark ignition engine it really isn't. All the heat-generating friction, but running throttled at a set mixture ratio means there is no unburned air to cool and insulate the insi...

Steve Lehto is enjoyable for many people to watch and/or listen to while they are doing another task -- similar to listening to the radio (he was a DJ as well -- the woman who speaks at the opening and close is a Canadian DJ).

Re: Running a Diesel with no load and no water

This is a lot of why Diesels run cool at idle in the first place.

I heard a story about a generator in some Siberian encampment that suffered a radiator failure, so they just bypassed the radiator. Ran all winter that way. I guess you can get away with a lot with -50 intake air.

Re: Advantages of electric cooling fans vs mechanical

Seems many diesel OTR trucks have Belt-driven fan clutch that is switched on-off electrically. Dunno if something like that could be practically integrated? it seems like an AC electromagnetic clutch would be the way to go to disengage and engage a mechanical fan as required? The way the OEMs do it...

Re: Advantages of electric cooling fans vs mechanical

i'd look to retrofit an OE electric fan over an aftermarket one as the aftermarket ones seem to be fairly under powered Very much this!!! OE fans tend to flow on the 3000-4000cfm range and have BIG, BEEFY motors that can power those aggressive blades to pull air through the cooling stack at high pr...

Re: Ford's Mystery Fix Explained

I'm not sure if you're criticizing my post or not and I don't know anything about Volvo's. The "leaking coolant into the cylinder bores" came directly from the Ford bulletin Kevin posted. I've seen lots of imagery of Ford engine blocks cracking out on top, like Volvos used to, is what I'm getting a...

Since WE are on the topic of Ford screw-ups, how are they doing with the 12,000,000,000 or so(??) little cars with the bad trans in them they sold before killing the transmission, IF Ford did indeed stop making/selling that transmission design?? Their Focus and Festiva cars if not mistaken?? Seems ...

Re: Ford's Mystery Fix Explained

Interesting, leaking coolant into the cylinder bores, possibly a marginal head gasket design?? I have a highly turbocharged 83mm bore Volvo. I have a head gasket failure, and while I have the head off I am going to shore up the block by hammering shims into the relief slots cut into the deck betwee...

Re: Freightliner (Daimler) predicts end of diesels in big trucks,,!

And in the end of it all, the battery's will all be recharged using diesel and coal. Not around here it doesn't. We split atoms to make steam. https://live.staticflickr.com/4699/25962586608_a99612c7e8_z.jpg It's interesting that natural gas is going up. I assume this is because we're using more of ...

Re: Does fuel movement in bowls during acceleration impact AFR?

Even if the jets remain covered and regardless of what is happening with the float and needle and seats, wouldn’t the relative increase in fuel level at the front metering block and the decrease in the fuel level at the rear metering block directly affect the emulsion circuit. As well as provide a ...
