"Ik heb een Perkins Prima uit een Maestro voor in mijn series, maar ik heb geen idee wat het motortype is."
Het blok heet "Austin Rover MDI" en is verrassend genoeg geen echt Perkinsproduct. Het gaat om een doorontwikkelde BMC O-series, waarbij Perkins slechts wat advieswerk heeft verricht.
Zie voor het verhaal in het kort:

Voor een langere versie heb ik hieronder e.e.a. uit een thread op een Maestroforum geknipt.
Als ik het goed begrijp, verklaart die gemengde herkomst waarom je geen nummers van Perkins terugvindt op het blok.

Hi I have a little pet hate which might make me unpopular on here, but really it should not because I think we all Love Austin Rover and Rover cars.
I really hate it when people call the brilliant MDI diesel engine as fitted to Maestro Montego Freightrover, the Perkins Prima
Its heritage is clearly Austin Rover as it was originally an O series that had been modified and had a Lucas CAV injection pump strapped to it. It was then further developed with the help of Perkins into the MDI diesel, the M standing for O series Derived.
For their efforts in assisting the design and development, Perkins were allowed to market a lower powered version as the Perkins Prima Marine engine.
Not that I have anything against Perkins they have made some average engines for commercial vehicles, I just don't think they deserve all the credit for such an excellent revolutionary engine conceived and developed by Austin Rover and friends :nonono:
Regards Gary

Not sure if I agree or not. The engine in question, is superb, and considering it was a pioneer of its era, i.e the FIRST direct injection diesel to be put into a road going vehicle (i.e the Maestro Van of the time) was a leap forward, where indirect injection had always been used before, and direct injection was reserved for tractors/generators etc. as it was just plain to noisy for a car! ARG were leaps ahead of all the others, ford, vauxhall etc and with this engine Maestro van ran rings around the other car derived vans of the time.
However, the Perkins attribute I don't feel is a bad one. Perkins is a renowned Diesel engine manufacturer, and this credits the engine further i feel. In the marine industry, anyone will tell you a Perkins is a dam good engine. Loads of people have said to me about my van, "has that got the Perkins engine in it......?", and when you reply "yes", you inevetably get a "that will go on and on....." or "you don't want to get rid of that then"!
If Perkins developed the engine with Rover, then they are entitled to some of the credit, and it was better than the japs making engine for us, and the whole thing did Rover a lot of good I think. At least they didn't bung in a Toyota engine or somthing! Its also good that it was based around an already proven unit, i.e the O series.
Really, it was a logical choice i think, Rover was already casting and machining blocks, cylinder heads etc, and pressing sumps and other compents nesacerry to build the O series petrol engines. With a few modifications, a simmiler assembly line could be created utilising some of the machining techniques already being used, as well as the casts etc for the major components. It would make things cheaper in that respect. Also the O series was the perfect size, 2.0 was the best choice to make a N/A and Turbo Diesel unit from, that would provide enough power and not be too sluggish.
I'll never forget when I was doing my apprentiship, the whole Perkings thing helped me out. During a part of training, we were taught how to identify petrol and diesel engines. We were then shown a random cutaway engine, and were asked to say if it was a petrol or diesel. I noticed it had Perkins written on it, so imediatly said diesel.
The instructor said, "whys it a diesel then", the response should have been, there no electrics, or its got injectors, or theres no HT leads etc. I said, "its a Perkins", response "what"? Amidst this group of puzzled faces I explained that Perkins only made Diesel engines, and he said "how the blooming eck do you know that" - Maestros and Montegos of course!!
Sorry if I have done nothing but type rubbish, but I am passionate about the Perkins/O-Series engine, particuly as every diesel today is a Direct Injection, technology has advance, and Rover has been left behind, and most people forget that Rover did it first, and better than anyone else!!

Hi Rich, I agree that Perkins are entitled to some of the credit as it was a joint venture between Austin Rover and Perkins, I think Austin Rover were more than fair allowing Perkins to market the engine as the Perkins Prima Marine engine.
Its just that Austin Rover seem to get no credit when it is referred to as the Perkins Prima in the automotive world rather than its correct name for motor vehicle applications.
I know I'm being petty but that's what pet hates are all about
Cheers Gary
