VERY VERY COOL!!!!!!!

What a fortuitous application of our venerable 1.6!

What's the context?  What are you powering and why?

my father had originally built the generator.He used it for power when he built his house.He eventually bought a fancy gas powered one and kicked this down to me. :D

Nice setup but I don't think I have ever seen a more rusty engine!

My dad and I really got talking about engines and generators this morning because of this thread, So I guess your taking the generator apart?

How much space did the overall design take up?

10KW is amazine... isnt it? what did you use for the coil windings to generate the power?

that my freind puts life into ol'mcgivers bones!
damn nice work tell the ol man from my ol man!
Cheers

10kw is about 14hp, the generator appears to be a manufactured unit.

As seen in the pic its mounted on a small frame  trailer.I do have the engine out ,and in the works.Blocks at the machine shop getting blueprinted,had to be bored out to 3rd oversize.Bought my pistons from MYKE_w (of course)hes been a great deal of help and wisdom for me.My IP has 10mm pump and head with LDA assembly from a peugoet 505.I turned up the control cone,replaced intermediate gov. spring.I found the experience to be easier then i thought it would be(i kind of psyched myself out)The hardest part of the IP was mating the LDA to the NA bottom end.here are some more pics. :D






I was going to use the gov spring from the peugeot,as it was stiffer,but i decided to go all the way with a piece of brass tubing cut to size.
more to come ....

so you could put 5 of those generators hooked up to this engine and make 50 kw? full steam ahead!!!

Dillinger1's Dad here. The generator design sat on a 4'x6' trailer. It took up so muchh space because I used the poly Jetta fuel tank as well; sitting that forward of the engine on the trailer.  The transaxle output powered shorted axle that was welded to a jackshaft which had a 14" dual belt pulley. The other side of the belt drove a 4" pulley on the generator's shaft.
To control the generator's speed under all load conditions, I put an electronic speed governor on the throttle and used an inductive proximity sensor to measure the pulses from the ring gear teeth. I tried using the cruise control circuit but it would not respond fast enough to hold constant speed under any load changes.
To start the whole thing in motion I started the engine with the clutch pedal depressed. Used a motorcycle throttle to change rpm's as I shifted gears up to 4th gear. I then would bring the rpms close to 1800 and then throw the switch to activate the speed governor.
The only thing I made a mistake on was not welding up the diff. I thought I could get away with bolting down one side of the transaxle output; thus speeding up the other side. This only worked for a while until the differential heated up after a long day of heavy laods. I was going to weld up the Diff but ended up loosing interest.
 All the generator parts are for sale now.

there must be a way to control that thing with the governor... i'd say calibrate the pump to cut fueling @ around 1800-2000 rpm.  then basically have two modes.  idle, and 'load' whereas load is full fuel travel.  rpm stays at 1800 because any sign of drop in rpm, more fuel is injected to hold that rpm... a very large amount of fuel can be injected to hold that rpm  :twisted:

i like how this was designed... keeping the gearbox to increase efficiency  :D

btw those pictures are somehow placed beside eachother extending the screen... very weird this thread is!

This is how it is done on a commercial unit. There are springs available for the VE pump to accomplish this. They are usually extensions spring with a fairly low rate and lots of coils. The constant speed springs replace the entire governor capsule.

How so? Every mesh of gears or belts consumes some power, best case would be direct drive.

This unit is for sale less the engine. Generator was $500, governor was $300, trailer/otherstuff about another $300. Asking $650
