Robot Cantina: 212cc Insight and Kubota Saturn.

[freebeard]

Every time I see the thread title I'm reminded of capturedbyrobots. ecomodder.com/forum/member-capturedbyrobots.html

IDK where the picture of his robot band is, but it was a real eye-opener.

Quite predictable that some adjusts to the injection timing would lead to a more suitable performance for an automotive application.

[Xist]

He normally averages 32 MPG, but received 37 on this route.

I believe he said he was driving 45-50 MPH.

He said he isn't doing aeromods so he doesn't attract police attention, but he has a belly pan under the bumper.

He didn't give an average speed for the wagon, but he averaged 73.4 MPG in the Kubota coupe at 42 MPH.

So far I saw one person suggesting a rear belly pan and two recommending a full-length stealth belly pan.

Someone asked about wheel skirts.

Come on you guys! You are trying to reinvent the wheel!

Edit! Someone mentioned LPG injection and I found:

Propane acts as a catalyst and raises the burn rate of diesel fuel to almost 100 percent. Of course with the engine now burning almost 100 percent of its fuel, there is a dramatic increase in horsepower and torque. Fuel economy also improves, as the engine is now using its fuel more efficiently. Propane also burns cool and clean, making for a cooler-running and cleaner, longer-lasting engine.

That's no catalyst! Propane Injection - Gas for Diesels, Fourwheeler Magazine

They failed to include the results.

I thought we had discussed it! Diesel + lpg = big mpg It seemed like the consensus was that it wasn't worth the added complexity of the equipment and a second fuel.

Yeah we all know its a scam
Some guy I never heard of. Oil Pan 4?!

What kind of name is that?!

Does he or she come from a long and proud line of... Oil Pans?!
He discussed at length in both threads that he tried propane injection in 2007, but saw great results with methanol injection.

There was also a short discussion of nitrous, CNG, and LPG injection.

I really hope that I have almost finished responding to ignorant comments like this!

4th gen Prius can easily do 70-80MPG driven like this... and it runs on gasoline and meets emissions.

Consider trying more mods: see if you can change timing to run atkinsons cycle? Burn leaner? Remove the turbo? That Saturn should be able to get to 100MPG on diesel IMO.

One does not simply make up numbers!

Your opinion is bad and you should feel bad!

Someone mentioned the Peugeot 208 II 1.5 BlueHDI 100:

With a fuel consumption of 3.2 litres/100km - 88 mpg UK - 74 mpg US (Average), 0 to 100 km/h (62mph) in 10.2 seconds, a maximum top speed of 117 mph (188 km/h), a curb weight of 2348 lbs (1065 kgs), the 208 II 1.5 BlueHDI 100 has a turbocharged Inline 4 cylinder diesel engine.
This engine produces a maximum power of 100 PS (99 bhp - 74 kW) at 3500 rpm and a maximum torque of 250 Nm (184 lb.ft) at 1750 rpm. The power is transmitted to the road by the front wheel drive (FWD) with a 6 speed Manual gearbox.
On the topic of chassis details responsible for road holding, handling behavior and ride comfort, the 208 II has McPherson struts front suspension and semi-independent, torsion bar rear suspension. Stock tire sizes are 195 / 55 on 16 inch rims at the front, and 195 / 55 on 16 inch rims at the rear. For stopping power, the 208 II 1.5 BlueHDI 100 braking system includes Vented Discs at the front and Drums at the rear.
The 208 II model is a Hatchback car manufactured by Peugeot, with 5 doors and 5 seats, sold new from year 2019 until 2021.

Awright! we hae anither yin!

German Vehicle Engineer here: down speeding doesn´t increase millage much. Right up to 70km/h, rolling resistance is greater than wind resistance and rolling resistance is actually really low compared to the engine power. The cubic behavior of air resistance really only shows effects over 160km/h. Down speeding only really improves milage on verhicles with high Cw values, or tiny engines that have to be driven to hard. For a average modern car, best mileage will lay somewear between 130-160km/h, only decreasing noticable over 180 or 200, but less due to air resistance, than through more acceleration and breaking applications, due to slower traffic.

Also most cars since the mid 90s have Cw values that are decreasing with increasing air speed.

I don't think much of that is true at all!

[Xist]

I believe that he mentioned filling the tank at the slowest speed, waiting an unspecified period, and topping off.

YouTube wasn't suggesting anything interesting, so I searched for "Double fuel economy," and found different scams than I expected--Shouty videos

Some guys released a video that didn't seem interesting, but they mentioned a 30-second top-off.

I wonder how much of a difference that makes.

I get better gas miles in my V8 than I did my inline four cylinder

What a maroon!

I finally reached the end of the "240" questions at the time I viewed this 6 hours ago.

Now there over more.

I am just going to assume they are mine.

All that I have done for 6 hours is respond to comments on one video!

I read Hacker News so you don'r have to.

Smokey’s new hot vapourizing engine creates heat in Detroit (1983) (rexresearch.com)
31 points by satchet 7 hours ago | hide | 9 comments

Smokey Yunick dipped a whole car body in acid to thin the metal and lightweight it [undetectable at tech inspection].

In this case he though if a warm air intake is good a hot air intake would be better. It took a turbocharger to force the air thoough the triple-stage heaters, but the claim was the fuel wouldn't precipitate so no detonation.

This little motor really is a GM V-6 engine block cut down to a V-2 cylinder. It’s turbocharged and feeds hot air and vaporized fuel to its cylinders. One of the most unique aspects of this design, as well as having GM engineers talking to themselves, is that this hot vapor system operates so there’s no detonation.

The first thing that strikes you about this engine is its size. “Seventy-eight cubic inches and 170 pounds”, says Smokey. Another surprising thing: There’s no cooling fan. In fact, there are only two quarts of water in the entire system, including the tiny radiator.

Smokey calls it his “Phase I adiabatic engine”. Adiabatic is an engineering term that refers to any process in which there’s no gain nor loss of heat.

A completely adiabatic engine isn’t possible, but the closer you get, the higher the engine’s efficiency and the better the fuel mileage. In other words, the less heat energy generated by the burning fuel that you throw away through the exhaust and cooling systems (much like the vehicles we all drive today), the more energy there’s available to move the car.

In 1983 we didn't have Internet. Heck, we didn't have overlapping windows on the desktop.

[Xist]

In 1983 I was 4 and we didn't have a computer in preschool.

Dad bought our first computer, a Packard Bell 8088, in 1989, and it had cutting-edge CGA graphics.

Just kidding.

The Color Graphics Adapter came out in 1981, the Enhanced Graphics Adapter came out in 1984--5 years before my first computer, but the year before you are talking, and the Video Graphics Array came out in 1987.
Strangely, so did SVGA.
The Extended Graphics Array didn't come out until 1990.

The 8086 came out in 1978, the 8088 came out in 1979--the year I was born, and both the 80186 and the 80286 came out in 1982, but we don't talk about the 80186.

So, I don't know what GUIs were available when I was 4, but it could have run on a 1982 with CGA.

I can't imagine having too many windows in 320x200!

If Dad loved us (and had vastly more money) he would have bought us a brand-new i486 with SVGA, which is funny, because I wish I had a modem, a dedicated phone line, and knew about BBSes.

I still don't know what GUIs were available in 1989, but I ran windows in 800x600.

The precise moment of inflection was when this ad ran during the Superbowl.

I'd give CNG a try, it might lead to the best results. Not only considering better MPG and eventual performance gains, but also lower NOx emissions and lower risk of knock compared to LPG.

Someone mentioned the Peugeot 208 II 1.5 BlueHDI 100

After the Fiat 1.0L engine was introduced to the Argentinian model exported to Brazil, I see a lot more of the 208 II than when it was introduced here only with the 1.6L EC5 engine.

[Xist]

Rather, one hood scoop, but forward, backward, and sideways, because his friend wanted to embarrass him.

He has some duct tape on the scoop, so I thought he would use that to attach it, but he used sheet metal screws, which means that he put another 4 holes in his hood when he installed it sideways as a joke!

He kept saying "For those of you who didn't pay attention" and "Pay attention!"

The last time I responded to dozens of comments pointing out what he had said and done in that and previous videos.

He said that everyone wants the intercooler installed behind the grill, where they normally go, but that would require too much fabrication, and regardless of what happens, the Saturn will go to the junkyard before the summer is over.

The car runs and drives!

What a waste!

He reminded us that his exhaust temperatures dropped 50°F once he installed the intercooler, but it didn't change anything else, and the conventional hood scoop improved a symptom, but not the root problem.

I don't remember the specific terms, though. I will edit this if I come across it without rewatching the video just for it.
