Don't leave that there - I'll take it to bits!

Refuse trucks and transit buses are the perfect application for hybrid technology, flywheel / kinetic systems are in use as well as (Parker?) hydraulic/pneumatic and elactric storage. The frequent start stop use allows plenty of energy to be reclaimed and reused in short periods. Electric and CNC are also very popular because of their use in heavily populated areas and generous grants. My favorite hybrid technology for refuse is the Wrightspeed turbine series-hybrid system (Ian Wright, one of Tesla's founders).
There are also municipalities experimenting with embedded charging systems at bus stops for use with electric buses.

EPA had (I think it's past tense) a significant project using exactly this process. A number of my friends were working on it and it was co-sponsored by Ford. There is a significant issue with mass and with safety - compressed oil at several thousand PSI that's delivered to the hydraulic wheel motors thru some sort of lines can be an ISSUE in an accident! Probably best suited for medium to heavy truck applications where the additional mass isn't such a factor as it is in a car.

The last I knew this project hadn't gone too far.

Um, NO! You clearly don't know who you're talking to. I did this stuff for a living and was there as the decision was made to allow sales of hybrids in the US. It was a poor decision made by non-technical people who didn't understand the issues. I've never read a word about this on the Internet though I have read up subsequently in the SAE magazine (I'm a retired member).

An analysis was made comparing the environmental impact of a Prius (could have been any hybrid) to an H1 Hummer, with the impact being fairly equal. Not saying that the comparison was completely fair but the fact that the comparison could be drawn at all is pretty amazing - and damning.

The real issue is that there are 3 stages in the life cycle of any vehicle, roughly corresponding to birth, life, and death. Hybrids are only OK at the "life" part, they suck at the "birth" part, and up until recently were terrible at the "death" part. (If you think I'm a knuckledragger, note how quickly I lauded the technology that allows hybrid battery recycling - I'm pleased for any genuine environmental advancements).

Like I said before, every so-called answer raises 10,000 questions. There are no quick and/or easy solutions.

My 84 "rolls coal" until the turbo builds boost because I had to remove a faulty ALDA. I think it was nice of Mercedes to point the exhaust tip at the ground on these cars.

The occasional dirty looks I get annoy me because my car is 32 years old and mostly original. Meanwhile my city is filled with kids driving new WRXs that they've completely straight piped. I think it's ridiculous they don't require emissions testing on new vehicles every year.

I know I'm getting off topic but the WRX kids are the worst. Their sole design goal is noise emissions, which is why they all run blow-off valves instead of bypass valves, and why you will even regularly hear (and sometimes see) dump tubes for their external wastegates. If I was a cop I would make a career out of impounding Subarus.

Naa, Oil of Odometer is better because it helps your car look younger too. . .

My memory of the origins of the coal rolling cultural phenomenon is that it entered into our collective consciousness before it ever really existed.

I remember there was this outpouring of alarmist news articles that were going viral on social media but they all cited the same interview with the same two high school students. The story was that diesel owners were "rolling coal" all across America, but there was no real evidence to support that. I mean sure tractor pulls, diesel dyno competitions and other forms of diesel tuning have existed forever, and you would see the occasional truck smoke out an intersection, but there was no political or philosophical motivation behind it.

But that didn't stop the Facebook outcry for something to be done about all these coal-rolling diesel owners! And if history has taught us anything it's that rednecks with a persecution complex get pretty obnoxious with their protests (see: giant confederate/gadsden flags on pickups literally everywhere) so pretty soon straight-piped diesel trucks with bed stacks and "PRIUS REPELLENT" stickers smoking out intersection became a daily occurrence.

I'm sure the people who helped the original story go viral were well intentioned, but in retrospect its pretty clear they added fuel to the fire (no pun intended) and made it pandemic.

That reminds me: my oil pressure gauge is starting to seep so I actually have "oil of odometer"

Fix the ALDA, there is no need to make smoke, it just wastes fuel until boost comes up.

How about this. You are dressed up going to a job interview / important meeting. The guy in front of you smokes the intersection out leaving you smelling like diesel fuel. ( and covering you car in soot / diesel fuel drops. ) Lets see how you like smoke now.

You have no right to be "annoyed" that others take offense to your rude behavior.

Whoa easy there bud. I think you are overestimating how much fuel a stock IP puts out.

My ALDA is broken, needs replacement. Wasn't the gasket. Haven't found a good one at a yard yet, but not for lack of trying.

I doubt he is doing anything rude... But many hoity toity green peace types look down on old cars in general. They seem to think if you aren't riding a bike, or driving a Prius, you are personally murdering the planet and their children!

Yup. I live in Boulder, CO, so all of that and more.

It's crazy. When I'm in my truck I get some interesting attention from the greenies and hippies in my area. Completely different than the reaction from the Subaru, which mostly blends in. Thinking about putting an Oregon Firearms Federation sticker on the Subaru, just to mess with people.

PM me your address and I'll send you a couple. I have the one from my MW pump from Mutt and the one on my back-up engine - I'll transfer the SuperPump over if I need to swap engines so I won't use either one. In fact, I'll be happy to send you a whole MW pump if you want it! As far as I know both ALDAs work - I know the one from Mutt's pump worked when I pulled it (attempt at more power - didn't work and I have the time slip to prove it!).

Dan

Thanks! PM sent.
