Engine Stand Dyno

[Banjo]

The 5K I bought off you recently is going just fine. I'll post a picture of it later. You won't believe how clean it now is.

 

 

Andrew, I promised you I would post you a picture of the 5K engine, to show you how clean it is now !

 

 

To fill you all in. This engine came from a KE55 that had been done up by someone, unknown. A 5K & K50 g/box had been added and the interior done up.

 

 

Anyway the cancer set in, and the car was doomed to be a "paddock basher" in a large orchard near Caloundra, where it was used to "get around" the orchard, on muddy tracks. When Andrew & I saw it, it had grass inside the car (growing I think) and you have never seen such a dirty engine. The car had more cancer that the Qld Health system, and there was only one place for the body. Back to Japan, to make more Toyotas.

 

Anyway, has just been completely cleaned, stripped, checked, valve grind & head skim; tested & ready to drop into my KE55 coupe.

Oh wow, that's such a cool little engine stand thingy, complete with an ignition barrel and gauges and stuff!!!

[Xany]

hey guys......we need to make one of them for the club.....wouldnt be that hard. :D

[Super Jamie]

THAT THING f@$kING ROCKS!!! :D

the things you can do with a welder and space

Thanks Guys ! Glad you like it. Well I have had a theory for a while that I could design & build a waste spark ignition for the K series, that did away with the distributor altogether, but avoided the complicated crank & camshaft angle sensors, common to other engines. I had proved it on the bench, but needed to go the next step, & fit to my 4KU engine. I had already decided that crank angle sensing off the crankshaft pully was not ideal, and I wanted to go flywheel sensing, due the larger diameter, & therefore less angular error.

 

 

To work in this area experimentally, you need the engine out of the car. Not delighting in having the engine in & out of the car several times, besides the point that the KE55 is a daily drive for my better half, I decided a working test rig was the way to go.

 

I toyed with the idea of a donor Corolla body with everything cut away, exposing the engine. for easy access. I then decided a test stand couldn't be too hard to build, and three bits of 200mm x 50mm hardwood planks from the nursery supplier, & a few 10mm coach bolts & screws from Bunnings, and there it was. It took about 4 hours to put together, designed on the run. Believe it Jamie, not a weld in sight, or required. It's totally self sufficent, and has wheels so it can be stored in the corner of the shed.

 

 

Guages are a luxury, but for $ 15.00 for a set of 4 off 50mm units off eBay, I could not resist.

 

 

Some of you might have noticed the hand accelerator made from the height adjustor of an old Rover 4 stroke lawnmower. I'm quite proud of it.

 

 

Anyway, the 4KU came off for the 5K, which needs to go into the KE55 coupe soon as it's 4KC is on it's last legs.

 

Then back with the 4KU and finish off the ignition system. Actually I experimented with the flywheel sensors today on the 5K, and they seem to work out well.

 

I'll post you some pics tomorrow of the sensors I've tried today.

 

I'd be very interested to hear from anyone out there at all, who has had a go at putting a waste spark or crank sensing on a K Series motor.

 

:D

you are THE man!!! :D

[Banjo]

Thanks Jamie ! Next job after I get the ignition sensors going is to "map" the engine over a wide range of revs & loads, for optimum performance, to program the ECU.

 

I'm open to any suggestions as to what I could get the tailshaft to drive stationary, to put a variable load on it.

 

 

 

Things I might be able to get my hands on cheaply, could be a big water pump, which I could throttle it's output, or an electric generator driving some dummy variable loads. (fence wire in a 44 gallon of water =) )

 

Any thoughts greatfully accepted.

 

:D

You'll be pleased to know that Nick and I were having a conversation about this tonight....we've decided to make one....if not 2 (it looks fairly simple) from the spare parts in our sheds...:D

 

With all the stuff i have laying around (gauges, coil packs, timber, metal and of course engines) i'm sure we could knock one up in no time.

 

You've inspired me mate....you should be proud.....

 

PS. One will be for the use of the club, and the other might be my own personal one. =)

[dysolve]

turn it in to a bit arse generator....... that will load it up....

[Super Jamie]

we should come up with a system to measure torque, perhaps you could load up a torque wrench and see where it clicks or something. horsepower being merely a product of torque and rpm, we could make the rollaclub engine dyno :D

[Banjo]

I'll do a search on the web tonight & see if any one lists a home made engine Dyno. Wouldn't have to be too big. Maybe a water or drum dyno of some kind, like the chassis type, car wheel drive on ones.

 

Water is very easy to control, as it's only a bit of plumbing & valves/taps etc.

 

 

 

 

 

I can feel a project coming on !

 

:D

Oh, and we'll need some virtual dashboard / dyno software !

 

Anyone seen any good cheap virtual instrument software, that we can hook up to this Dyno ?

 

I've got access to plenty of data loggers & kilowatt hour measuring equipment.

 

 

:D

SORRY...........meant to post in another thread.

You can still buy them new I think...

[Super Jamie]

scott's old auto rubber

spectrum auto rubber

google or whitepages

start a new topic if you have a new question

 

acutally, perhaps the engine dyno thing should be its own topic too :D
