Hello
I'm not an instrumentation guy, so I can't give you many details or nuts-and-bolts explanations. I can physically see these devices and know basically what they do. Engine control is a ragtag combination of Alltronics, Woodward, and local talent. It's surprising it works as well as it...
Hi Bill
Our engines have a little different problem. The composition of the biogas is fairly consistent, but the pressures can vary significantly. If our pressure changes too much, the engines switch over to utility natural gas. It's a fairly smooth transition.
I can't imagine any system that...
Hi Bill
We run naturally aspirated v12 Superiors on biogas. Assuming our temperature sensors are correct, exhaust temps generally run from 600-650. This varies a bit with changes in AF ratio and timing.
Cheers
Eeeewww!
Every time I hear of dioxans or furans I shudder. These are the same things that have killed many streams and rivers with pulp mills located on them. Granted, some derivatives of harmful parent-compounds are quite benign. In other instances, it takes a generation to realize and/or admit...
Hi Moving
The relays I'm used to using have an amp rating. I would say the easiest thing to do is use just one relay. Find out how much your horns are going to draw. You may have to buy a bigger relay. Having said that, there will be more juice flowing through the primary wires. Are they up to...
Hello
I used to own two old Chevy pickup trucks with the closed driveshaft. As I remember the actual driveshaft was solid steel about 1.25". There were bushings inside the tube. One end of the tube was permanently attached to the differential. The other hooked up by a threaded casing to the...
Hi Kenre
Not quite clear on your description, but........The top(? inlet?) of the water pump will have the lowest pressure. You could only run it from there through the converter into some kind of recovery tank or something. I.E. it won't normally go that direction. On my vehicles, I hooked up...
Hi
I tried searching for this but couldn't find anything in this forum. Saw these ads in flyers for electronic rust protection. Seems it uses cathodic/anodic/electrostatic electicity. See counteractrust.com .
My first impulse is 'snake oil!' But I'm still open minded. With all the different...
I spent a day just varying the gap and observing the results. I adjusted the timing to optimum after each gapping as well. I got the best performance with a gap just smaller than that which caused a misfire. I also noticed that the smaller gap caused pinging more readily. As mentioned, real-life...
Hi allornothing
Before you spend megabuck$, here's a few cheapo tricks that might work. If the impellor doesn't already have one, you can install a circular sheet metal disk at the back of it (spot weld it, no rivets). Also try to move the impeller back or forward on the shaft to optimize the...
Hi zdas
One thing that hasn't been mentioned yet is the viscosity of the lubricants in your vehicle. Everything is a bit 'stiffer' when the ambient temperature is lower. Ever notice how many grades of oils and greases are on the market? Most of us don't have the time or inclination to switch...
Hi Blob
I've actually done this before. I noticed 3 things:
1. There was an improvement in fuel economy. Noticeable but not much.
2. The vehicle had better acceleration from a standstill.
3. The engine pinged quite a bit and the timing had to be retarded.
The engine ran well when cruising but...
Good call. That would certainly take care of the responsiveness issue. How big would this thing have to be?I'm not into hydraulics, so I'm assuming the accumulator system would be solenoid valve activated to prevent recirculation? Given the high pressures, this would make things a little more...
Hi
Yes, that was the machine I used. Don't recall what company supplied the software - some outfit out of Colorado. Their program was a little slow and excessive. Once I learned the commands and language (BASIC), I used a stripped-down version that suited our needs better. If you need any other...
Hi
I'm in to tinkering big-time. I would like to make an electric on-demand power steering system for my car. I want to reduce the drag of the full-time power steering pump. I know it doesn't use that much fuel but I want to have as much fuel economy and power from 'my precious'. A lot of my...
