Possibly, although that may be confusion with the 2.0/2.25/2.5 diesel that preceded the Tdi, which definitely used the Ricardo Comet precombustion chamber. I don't think Ricardo had anything to do with the redesign of the engine for direct injection.

Ricardo?

dont hide your info under that bushell




please note how I'm not doing a daniel joke---

Ricardo are one of the big independent engine development and engineering houses, although it looks like their scope goes much further these days.

They were still heavily involved in independent consultation in racing back in the nineties.

I thought the same thing at the time John and have no idea who was involved in refining the Tdi head.

As much as I've poured scorn on the Tdi here over the years (usually when it's let me or a mate down!) It's an incredibly efficient head/piston/chamber design.

Perhaps worth pointing out that when the 2.0 diesel was introduced in 1955 it was one of the first small high speed diesels anywhere. Mercedes and Citroen had them earlier, as did Standard, but the Rover engine was arguably superior to all of them, especially considering the long line of developments from them. Interestingly, all of these early small diesels used Ricardo Comet precombustion chambers. As did most of the other successful high speed diesels appearing from about 1939 to 1970.

Harry Ricardo was just about the first engineer to put the internal combustion engine on a solid scientific basis, starting with the engines in WW1 British Tanks. He developed most of the basic ideas about how combustion occurs and how to improve it between the wars, and formed his consultancy in that period.

Freelander TD4............?

What do you mean by hi speed JD ??
