Generators / Capacitor calculation for DIY stand alone genset
« on: April 29, 2021, 08:29:20 AM »
I am building a homemade genset consisting of a Lister SR2 and a belt driven asynchronous motor as generator. I am in no way proficient in the electrical field, so this is also a learning project. I have tried to calculate the right size for capacitors as this will not be connected to the grid.
I've found two different equations on the web.
Equation one returns 108 uF
Equation two returns 62,5 uF

Could anyone say which is correct or come up with a valid equation of size of capacitor, before I start throwing money at useless parts :-).
I am planning to build a redundancy setup with 2 engines and 2 gennys on a common shaft, to mitigate breakdowns and service, so a valid equation would be very nice.
Thanks

Engines / Comparing fuel consumption HR2, ST2 & SR2

This may be of interest when choosing the right engine for your project. Data for straight diesel taken from Lister instruction books.
Cheers Chris

General Discussion / Engine identification Lister-Petter HR2
« on: April 09, 2021, 06:04:32 PM »
Greetings. I have this very nice Lister-Petter HR2 sitting in my barn. As far as I understand it is a
HR2
CCW rotating
Built in 1990
Number 95 produced that year.
I read somewhere that the numbering system was changed in the eighties, so I am in doubt if it is correct.
What does 910 stand for? 
The engine plate reads
4000095HR2A910

Thanks
(It starts very easily and sounds so beefy – waiting for oil and filters before running it again)

General Discussion / Engine identification SR2 or LR2 or LD2 or SL2

Greetings from rural Denmark and thanks for letting me join in. This is my first post and I am new to Listers and diesels. I have for some time thought about making a homebrewed genset for my homestead and before I long had five aircooled Listers sitting in my barn.
Two of them I think are SR2’s. One of them has no engine ID plate and the other has a rather odd plate, indicating that it may have been produced under licence at a Portuguese producer, but no numbers to indicate model or build year. One of them came with a lister gear
I hope you guys can give me a hint as to which design details reveal the true model and year of these two engines.

Engine 1(my guess is SR2)
Fixed rpm
Cast in crank case: 202 50012
CW rotation
It has inlet cold start cups
Says “Lister Diesel” on rocker covers
Engine ID plate says:
“Metalurgica Duarte Ferreira
AV. Dom Carlos (21??)
Lisboa Portugal”
As far as I can see Metalurgica Duarte Ferreira was a Portuguese farm equipment manufacturer that employed 800 workers at its peak. The company existed from about 1900 to 1984.

Engine 2(my guess is SR2M)
Variable throttle and mounted with Lister gearbox with forward and reverse
Cast in crank case: 202 50012
It has inlet cold start cups
CW rotation
Says “Lister Dursley England” on rocker covers

Thanks
