I'd go with ECE because its a government regulation enforced in the EU rather than a voluntary marketing badge as far as i can tell.

Snell isn't just a "voluntary marketing badge," it's the standard required by nearly all motorsports organizations in North America.

Sagebrush posted:Snell vs ECE is a huge shitfest akin to "what oil brand is the best" that's not worth getting into. Both are functionally equivalent and if you buy a (full-face!) helmet with either rating you'll be as protected as you can be. The difference you run into, is that not all brands/styles/etc are Snell tested/stamped, especially in ADV helmet genre. My race car helmet (not even full face) is Snell SA2015 because rules, but the likelihood of a helmet helping much with an AW11 autocrossing is, meh. https://www.amazon.com/gp/product/B01N1UG544/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 My motorcycle helmet is and will likely always be ECE. http://www.klim.com/Krios-Karbon-Adventure-Helmet-ECE-DOT-3510-000?quantity=1&Size=112

Cojawfee posted:^^ How does auto stop/start work with a manual? Auto start/stop is best with a manaul, just like most things automotive. N + Brake only = auto stop. Touch clutch or gas = auto start. This makes it very easy to engage the system when you want it and inhibit it when you don't. The timing also works better as the "engage clutch, shift to first" sequence lets the engine fire back up just in time for you to hit the gas. Unlike in automatics, where the lag is more noticeable because the engine doesn't fire until you take your foot of the brake, requiring you to pause for a second before hitting the gas.

theroretically, with auto-start/stop on a car with a ~20hp starter/alternator, you could just leave it in first gear and hold the brake until it stalls, then hit the gas to get going again, leaving on electric power until the engine is at a high enough RPM to start firing.

How do they deal with air conditioning with these systems, go to an electric compressor?

The Locator posted:How do they deal with air conditioning with these systems, go to an electric compressor? You have to differentiate between an On/Off AC and a variable compressor AC. the first ones have a core with a lot of thermal mass so that they regularly go off for half a minute or so during operation without a noticeable shift in temperature. You could do just the same on a variable compressor AC to bridge the time until the engine runs again.

Yeah if it's really hot out my car won't even bother with the auto stop. Same if you have the AC in defrost mode.

Hmm.. how does the stop/start work on the newest GMs when the ac is on? I heard the latest Malibus doing the auto start bit in the middle of summer with the windows up. I'm guessing they just cycle the engine back on when the evap temp gets too high? I have no idea if they had auto climate control or not, but I know it gets muggy as gently caress in a hurry in every car I've had with ac if the fan keeps running after the compressor cuts out/engine stalls/etc. I was impressed how quick they fire up though - it sounds like 1 or 2 rotations. I know GM moved to a 58 tooth CPS trigger across the board around 2007-2008, I assume that helps.

I had a Sonic with auto-stop as a rental a few years ago. Seemed like more that half the time it didn’t even engage the starter - it just instantly restarted. I later read that the ECU was set so that it would stop the engine so that two of the cylinders were right after TDC and could restart the motor by firing the appropriate plugs, no starter needed. I thought it was a neat solution.

I have no idea if they had auto climate control or not, but I know it gets muggy as gently caress in a hurry in every car I've had with ac if the fan keeps running after the compressor cuts out/engine stalls/etc. On my Lacrosse, there are 3 A/C modes - off, Eco, Max If set to off, autostop will keep the engine off until the battery reserve drops to 12v, then the engine kicks on. If set to Eco, autostop will keep the engine off until above, or the measured in-cabin temperature or humidity delta hits a certain threshold If set to Max, above except the delta threshold is significantly less Max defrost will override autostop, but you have to manually select it (system reverts back to previous climate control setting after you stop the car and exit) In any mode if you change the gear shift selection or any climate control setting (temperature, fan speed, mode) the engine kicks back on. I keep mine on Eco, and only on the hottest/most humid days do I even notice. About that time the engine kicks on. It's a pretty slick setup.

netwerk23 posted:It's not horrible but it's a failure We had a f550 dump truck at work that was designed poorly. Every time you lifted the bed and drove forward (you know, to get all the poo poo out of the thing) the mudflap would ride up on the tires and then stay there when you drove. If the mudflap was down when it did a regen it would do what's pictured, melt. It must have been a friday at shitspreader factory because that thing was all sorts of awful. EDIT: also I bet that's a cement mixer in tow, they usually have their chains connected like 3 feet back from the hitch. I have no idea why, but I can only imagine it's a shitshow if they jump off the ball. Every cement mixer I've ever towed has been like that. chrisgt fucked around with this message at 00:03 on Nov 7, 2017 |

Unless that state has laws about a tailpipe exiting at the rear of the vehicle/behind the rear axle there's no reason they can't sawzall it right past the muffler and put a downpipe on it.

Not a good idea on those, the exhaust gets really hot during regen and the shield around the end helps keep it cool by convectively sucking air around the exhaust pipe or some poo poo. A dump straight down would set grass on fire.

IOwnCalculus posted:I have finally learned what the hell those vents are for. They also help introduce oxygen to any flames your exhaust may be throwing. https://www.youtube.com/watch?v=LWOD805Rg8c Newer highway trucks with a catalyzed DPF and SCR don't even need stacks. The exhaust comes out clean and cool enough to just be dumped out the back like a pickup truck. If you drive them hard enough, it can regen passively and you never actually have to run a regen cycle. First gen DPF trucks had to get the filters up to 1700*F, catalyzed filters only have to get up to about 1200*F, which is a normal EGT if you're really hammering on it. Spray some DEF into it and it's down to 400*F at the end of the pipe.

Like they couldn't spend 20 cents finishing it after shoving it through the stretcher. Also, more related to horrible mechanical failures. the GM DEF tank location.  If you damage it and lose your fluid, you get limited to 5mph. Horrible visual failure, for 2017 they added a plastic skid plate

The mileage thing is completely bunk with that type of usage - even going by VWs numbers the best diesel Golf does 3.9l/100km and the best petrol 4.8 and given real world short trip usage it's going to be even closer.

I'm in germany and i just ditched my diesel car because every loving problem i had with it was related to the overly complicated system to get some kind of power out of a diesel engine while trying to keep emissions down. Every loving thing broke and was ridiculously expensive to fix. gently caress that poo poo. Taxes are way higher here for diesel cars but since the fuel is much cheaper and you get better mileage it makes sense for a lot of people who drive a lot to drive a diesel. Most company cars are diesel for that reason. But since there are always rumors about banning diesel in cities and making the fuel just as expensive as petrol i just figured i'll gladly pay 200€ a year more for fuel for never having to deal with the loving additive injection system on a DPF again!

That and the efficiency gap between diesel and gas is pretty drat small these days. Even with the latest emissions standards you can't escape the fact that in terms of CO2, diesel produces more CO2 per gallon. A gas car getting 40mpg emits about the same amount of CO2 as a diesel getting 50mpg. MonkeyNutZ fucked around with this message at 11:54 on Nov 7, 2017 |
