Common Rail Direct-Injection Diesel Engines

[inamk]

Where can I buy common rail direct injection diesel engines of 50 100 hp size?

Does any one has experience of using on a yacht?

Volkswagen electronic direct injection? Volkswagen Marine >*Home*<

Quite common for automobiles where usage v cost is favourable, and the service garage is just around the corner. Not so with marine, with ECUs and all that.
IMO, if it was a good application, we would see many using that technology.
I work a lot around Europian race cars, very expensive dignostic equipment required.

Most modern European engines are common rail Volvo pent D3/D4/D6 new yanmars etc, but not yet common in under 50hp but D4 would fit your bill.

Common rail is a very proven system , pioneered by Fiat and refined by Bosch. It can be mechanically, or hydraulically controlled. But in modern engines to comply with environmental standards and fuel economy it's generally electronically controlled. In the near future all engines will so to comply as it's virtually impossible to comply with mechanically governed systems.

Despite the previous poster virtually without exception all European diesel cars ate common rail ECU controlled. It's in widespread use.

We agree. I was generalizing as regards the OP query, and yacht application.

Diesel race cars? I always learn something new...

What exactly is a common rail diesel? I have an older VW TDI Passat which i dont believe is common rail but is turbo direct injection which is computer controlled that i think would be a fantastic boat engine, at 90hp i think a pair of these would be great in a power cat, im also a bit concerned about the use of computer controlled engines in a marine enviroment,however it has proven extremly reliable in the car and we can plug it into a laptop to diagnose problems as well as change settings so thats a plus.

I'm presuming you are joking, right? Audi has been winning the 24 hr LeMans, and other races all over the world for about 6 yrs now with their diesel LMP cars. Puegot is now right up their exhaust with their diesels. Very big business.

Your Passat has common-rail injection, but I would not use it on a boat. Not only the electronics could be prone to fail in that environment, but any repair can be complicated compared to a regular Yanmar. I had one (never had a more reliable car) and I confess I never took of the plastic lid off the motor. Can you imagine being stranded because the exhaust oxygen sensor went mute?

Most good turbo diesels outperform their petrol equivalents in Europe now especially in mid range performance. I drive a chipped Range Rover diesel that outperforms the supercharged version.

Diesels rule the world.

Is there a kit I can use to upgrade my Detroit 8/71?

I think it's called "core trade-in" 8-71 the marine Clydesdale

[lorenzo b]

But I just bought it as a core, and down here in the third world spare parts are laying around in peoples back yard and kids can rebuild them. It's their version of Lego toys.

They are like zee's 'skeetas--they are everywhere. A bit of a thread stray, but I swear this is the truth.
I know of a 6-71 that had been out in a field, with generations of goats moored to it for years.
Guys rebuilt it, and it now runs hard in a commercial boat for about 5yrs.

The skepticism is unfounded. Modern ECUs are reliable and you treat them as another spare part like carrying a spare starter or injector. As to sensors these are simple field replaceable units and the ECU will at least tell you the fault.

These concerns were exactly the same as when turbochargers appeared on small diesels. Now they are commonplace.
