WTF, first fuel, now DEF?

[Rusty PW]

Wasn't talking intake air - when the air is colder, you have more of it packed into a given space. You can gain on the track by opening the hood and cooling the engine bay area down between runs. It's not a huge amount, but counts for tenths.
We usually run "test and tune" on Friday evenings and the cool humid night air by the Mississippi helps. The engines were still hot, but the cool air going in was good.

After I posted that. I reread your post. Yea...you was talking about pushing a car through the air.

My track sessions last 30 minutes or so. Road course. After a session, EVERYTHING is hot. You can actually stick the brake pads to the rotors if you don't move the car a few feet after parking it. I run a diff cooler to with a temp gauge. I've seen temps over 300F without the cooler. With the cooler and fan turned on. Temps stay around 200F.

Diesel engines should be the future of motor vehicles, but they have been regulated to death by big gov. The push for electric which is so stupid as they are far from being "green".

They are also a healthy food. We used to buy steelhead in the store until the prices got really crazy. I prefer it to salmon although I really liked the fresh Alaskan salmon we had at a salmon bake up there. Man, that was GOOD.

I hate salmon with a passion. When I was younger. My dad would go salmon fishing with all of his brothers. My dad would bring back coolers full of salmon. I ate salmon every way you can fix it.

My oldest stepson bought 45 acres of land just outside of Bailey Co. On the edge of his property is the North Fork South Platte River. GREAT fly fishing. Along with bear, mountain lion, deer and big ass elk.

Maybe in your personal opinion because you are emotionally tied to them, but they are among the most dirty engines out there. It is nearly impossible to cheaply make them as clean as even a not very clean gas engine.
They have advantages, some big, but they are dirty running engines, cost a lot more to make and maintain.
There's a reason you aren't seeing a push to put them into cars and yet newer gas ICE are coming out that are so clean they rival electric.
You talk of "big gov" - it's science that's the reason there aren't more. Strong, reliable, plenty of torque, but dirty.

If people get beyond the emotional preferences, and do some digging........

You couldn't give me a gas tractor to do field work, real work, pull a chisel plow, pull a tile plow, or use as a utility tractor, but gas in a car, "SUV" or light truck is logical.

1. I'm not tied to diesel motors as I do not own any.

2. You are wrong about them being dirty. A modern diesel engine emits almost zero pollution. You can have one running in your garage and you'll get a headache, it won't kill you. There can be a happy medium to a diesel engine emitting pollution and being very reliable and get excellent fuel economy.

You are some what wrong on this. Yes, the engine runs better when warm. But loves cold air going into it. Especially on a turbo or supercharged motor. If the Air intake temps get too high, the ecu will start to put timing to reduce power. On the dyno with my twin turbo'ed 700hp track car. A 65F morning, hp was 703. Late afternoon 90F. Power was down to 623. Nothing was done to the car between the runs.

At the power plant with gas turbines. We could see over a 100MW' difference between a 90F day vs a 0F day. That's a HUGE difference.

Thermal efficiency at it's finest. Mobile nuclear power plants, and I would imagine those that are stationary see

Steelhead are a trout but they spawn in rivers and migrate to the ocean much like the life cycle of salmon, they don't die after spawning like a salmon though.

I mean, technically they are the same species, just one makes it to the ocean and one doesn’t. And I think that they are “salmonoids.”
Oh yeah, price of DEF bad….

Yes. I find it amazing personally.

Nuke is the way to go. It's the cheapest per KW to product. The problem with it is what to do with the waste, the cost of getting permits (avg cost is around $7 billion) and the NIMBY's.

Hydrogen is the way to go with ice powered vehicles. What comes out of the tail pipe is water vapor. It's easy to convert a gas engine to run on H2. The problem is producing enough to meet the demand. And in a crash. H2 is invisible when it burns.

There is talk about using diesel engines instead of gas engines in hybrid vehicles now.

Did they make you go sit in the corner of a round room and fold fitted sheets?

Who folds fitted sheets anyway?

I’m sure the diesel hybrid will love being turned off and on over and over thermal expansion and cooling will really make ‘em last ?

I rented an electric golf cart, holy crap just a couple miles and a couple hours use overall and the damn thing was 20 bucks. I guess I could have walked and saved 20 bucks.
Paid 10 bucks for some DEF and went a few thousand miles. I guess I could have walked and saved 10 bucks.
Looking forward to fishing on Friday..

The problem is that it takes a lot more crude to make 1 gallon of diesel than 1 gallon of gas, so technically the consumer may get more mpg, but it takes more crude to get there. So if we all moved to diesel, we'd need more crude to do it.
Off and on is bad for diesel, it's at its worst when in stop and go driving. That's when the real "dirt" comes out, NOX and things London has found is impacting health in the city.
Constant higher speed, highway speeds and modern "cleaning systems" clean them up, but the fact is, most wouldn't be used that way - they'd be used in stop and go where things get dicey for them.
NYT even had a piece on that a while back.
As far as diesels running in a garage and not killing you - uh, same for cars with gas engines. Modern cars don't crank out CO like in the past so those TV shows where the producers don't do their research and still to this day show someone committing suicide by car in a closed garage - the person may as well take a couple meals, maybe some popcorn. They'll be there a while.

We gave up - my wife keeps having us start to fold them, then a few seconds later they just get rolled up and put away. She'll eventually stop trying.
