I still have a print out of that article from the 90s (Canon Bjc-200 ftw). Exp2 was neat. GM did a ton of the pioneering work... They were waiting for in-cylinder pressure sensors to come down in price... So maybe they’ll be close behind.

Came here to post this...lost the race.

1) I do believe these engines will burn more oil and that will be annoying. I don’t believe that on a stroke-by-stroke basis the oil volume will so impact the octane as to make the difference between a 12.5:1 and 13:1 compression ratio or anything. Nor do I believe the small volume will hurt the cat. I doubt this…

Since I learned about Miller and Atkinson cycles back in college (2006ish timeframe), I’ve known the Atkinson cycle to cover both early and late valve closure. I always liked the early valve closure in concept, as to avoid pumping losses. However, I’m guessing it was avoided by most OEMS in the name of reduced oil…

I have found some pretty awesome car enthusiasts at really high end dealers, as you described. I was very pleasantly surprised.

That’s the thing you always notice with some of the market leaders in safety...especially Volvo. When new tests come out, cars from Volvo almost always do just fine. From memory, Honda, Subaru, Chevrolet, and Ford also tend to do quite well. It seems that several of the other European companies fare poorly and Toyota…

Does that mean that everyone from Toronto and the surrounding lands in Ontario is moving there?

The peak times on the grid are around 5-10 at night. With most cars needing less time than that to charge, simple time-of-day pricing coupled to scheduled charging (my Volt can be set to charge after a certain time) should largely enable pretty widespread adoption. It’s not like most cars will need a full charge every…

As for SAR, it’s certainly claimed to be relatively impervious to clouds, but I doubt either of us know (or maybe you do and cannot say) what the actual effect is. I do know that in the 2020s, F-35 will likely get an upgraded, GaN version of it’s radar which should double capabilities, so that capability will only get…

The F-35 SAR is quite a bit more detailed than previous aircraft (with the exception of perhaps the F-22 APG-77). The mapping accuracy would appear to be capable of mapping out threats and, using the internal database, calling them out. F-22's APG-77 radar can identify the airframe of an opposing fighter from a long…

I think the story in question had the guy come down at over Mach 1 and then do a high Alpha 180 to sorta throw a wave at the ground. I’m sure if he did anything of the sort, it was awe/terror inspiring depending on one’s perspective.

More likely, the pilot of the F-35 (the guy who would really be making the decision) would point his steed towards the problem area and arrive several minutes sooner than the A-10. He would then, from a comfortable altitude, use synthetic aperture capabilities from his APG-81 radar to map in excruciating detail the…

Sounds like a helluva guy. Tragic loss. Thoughts for his family and friends.

I’ve spent some time in our nuclear hot cells. That glass is like 22" thick or something to shield the radiation. You’d never know looking through it...at least until you move something away or towards you. A several foot movement looks like less than a foot due to refractive effects. But stationary stuff looks pretty…

I actually think they’re better set up to do F1 engines than road engines, as odd as that sounds. F1 engines seem to be a very specific discipline (without a ton of carryover to road engines), with much of the talent located in a small area of England. As such, I totally agree that they could hire their way to an…

I’m sure they had plenty of input, just like I do with my suppliers in my industry. It doesn’t change the fact that I’m not the expert, nor the designer. It’s more than possible that they’ve learned enough to start doing it themselves, but until they do a clean-sheet design, they’ll remain a buyer, not a supplier.

It’s a 1990s Nissan endurance car engine developed by Ricardo into a privately labeled McLaren engine. It’s like new mowers with “Cub Cadet” engines, which are the same Loncin engines run on Toros and sold in Northern Tool.

29% of electricity comes from renewables in Germany, with biomass and hydro comprising about 1/3 of that 29%. So yeah, it’s nowhere near that close. Germany has a huge amount of coal generation. They might be one of the better countries to make this argument in, with 40% of the power coming from coal, including 23% of…

Considering the new Prius gets at least 15 MPG better average than a Skyactive-X Mazda 3 by using a 1.3 kWh battery pack (about 1076 MJ of manufacturing cost=~9 gallons of gasoline), I’d say they’re excited to have an enabling technology to make their hybrids even better. Don’t be shocked if the peak efficiency of…
