Our company has a standard information and design table in our part and assembly templates that we use to populate drawing title blocks. We also have a standard traveler that is excel-based. What I am trying to do is insert a button in the design table that will launch and auto-populate the...
By closed loop, i mean the ecu is using the oxygen sensor to change the fueling. You should attempt to disable this and see if the engine continues to oscillate.
that would be a waste of time. If you're still using a narrow band sensor, as long as it's transitioning across ~0.5 volts the amplitude is not terribly important. Also, to carnage1, the ecu "should" have software filters and calibratable psuedo-PID constants to prevent oscillation. I haven't...
Yeah I understand the push behind its implementation, but what I didn't understand is why all the proposed systems I've been coming across are for loops that can be run either in HVAC mode or reversed and run as a heat pump, whereas I've never seen this functionality in a 134a system before. Any...
I'm working on the development of vehicle that will most likely be required to use a CO2 HVAC system. In doing some research, i found quite a few references to the development of automotive CO2-based HVAC systems that can also run as a heat pump. My question is, why is this only being explored...
I saw that course, it looked like exactly the info i was looking for, but I'm way out in CA.
Thanks ISZ for your feedback, especially the worst case ideas. The application is combined on and off-road. I have a pretty good feel for the on-road points, but off-road i'm not so sure about. As for...
I was wondering if anyone can recommend a text for vehicle cooling system design. I'm looking for a book that covers:
-general discussion of system design
-the critical design points (idle, speed on grade, others?)
-acceptable radiator performance estimates (hard data is hard to come by if you...
I've read (mostly on enthusiast forums that I don't trust) that the steps are there for one of three reasons:
1: anti-reversion
2: velocity changes
3: Creation of a step change in area for pulse tuning
Is it one of those, a combination of those, or none of those? My intuition is that it's not...
Looks like Shaggy's selection allows me to do what i need! for the most part our company tends to avoid the use of solidworks library, not really sure why because i haven't been here long. thanks to the both of you
We're designing a number of hydraulic manifolds that will have a number of J1926 ports machined of varying sizes. What I had done is created one part that is basically a "plug" of the port cut, then another part that is the main manifold. I then inserted the port part as solid body and did a...
Hate to thread-jack, but...are california building codes posted anywhere that describe what measures have to be taken for noise, exhaust, chemicals, etc? We want to install an engine dyno for r&d purposes and we're wondering what it's going to take. we'd hate to build a "nice" room only to find...
I suppose, but it seems like there is still the difficulty of dimensioning a fairly involved 3D sketch in a way that's easy to understand on a piece of paper. That's why I wanted the table of point data.
