Re: De Dion rear end design..

Brian P Yes, I got a look. I didn't realise that this had been used by Honda. Interesting set up. Ah, "the Honda way"! There is another system I came across which is kinda de Dion. The Alfa Romeo 8C had a solid beam axle rear suspension. There was a twist* to it though. The differential was directly...

Re: Steering

pdq67 Tiller steering! That is neat! I went off and did a patent search after reading your email and viewing some of the leads in yuor link. There are actually quite a few tiller mechanisms for cars. An interesting one is Lanchester's patent. It is a tiller steer which even has Ackerman geometry bui...

Re: De Dion rear end design..

Brian There is a Honda HRV not far from here. A neighbour's wife (I think) has it. I ought to go over & ask if I can have a look. Was Honda's objective with the 4wd in that car to deliver benefits in low traction conditions? Was that the idea or was it for reducing understeer or addressing some othe...

Steering

Here is something interesting to consider. Some while ago an editorial appeared in Racecar Engineering magazine wherein the editor discussed an idea he had come across. It seems that he'd been involved in a discussion with a human factors engineer who said that many of the primary control arrangemen...

Re: De Dion rear end design..

Speaking of de Dion rear suspension, I found some interesting correspondence in the last few issues of Racecar Engineering magazine. It is between Mark Ortiz (who writes "The Consultant" columns) and a reader. They are discussing means of revising the rear suspension of the Lagonda. A twist beam de ...

Re: De Dion rear end design..

Hi Billy Looks to me that what Jaguar (was it their design engineer Harry Mundy?) did in the XJ series 1, 2, 3, XJS and XK8 (looks like some of the Astons used these components as well) was to arrange the axis of the lower wishbone pivots to slope upwards. The trailing arm seems not to be a critical...

Re: De Dion rear end design..

The challenge, "Perhaps with enough digging, someone could find an OEM example of IRS with significant anti-squat." Took a bit of time to find anything, but what about Jaguar E-type, XJ Series 1,2 & 3 and also XJS? They appear to have anti-squat and they are IRS. Jaguar certainly claimed they had an...

Re: C.I.H. engine

I've done a bit of searching around and reading (including the links provided here- thanks for those). Seems like the CIH engines were quite successful in motorsports. The four likes to rev. What was the CIH six like?

Re: C.I.H. engine

Wow! That is a great drive! That car handles well. Exciting when he nearly lost it. Thanks for this video.

Chevyfreak, you mention that German tuners were hugely involved with working the CIH. Which ones were they?

C.I.H. engine

Many years ago my mother purchased an Australian built sedan. It was unusual in that it was powered by a German built engine. The engine was a four cylinder Opel CIH (cam-in-head). The Opel CIH was a family of four and six-cylinder engines. In this Ozzie application the engine was a four cylinder of...

Valve gear and springs

A while back I aked about rev kits. Since then I have ahd a chance to read up a lot more about them. This brings me to a question for which I have not found anything in the literature. And here it is! Why not use the rev kit springs located concentric to the pushrods in the valley to control the ent...
