The modern race engine is something of a technical marvel, not simply in terms of power output but also reliability. In terms of the basic concepts and the components involved, however, there is very little that the race engine designers of the 1920s... read more

Could steel rods be the optimal solution?

Friday, April 05, 2013
Comments (0)

There have been a number of RET-Monitor articles on con rod materials over the past few years. The last article to cover steel as a con rod material, in late 2009, discussed the general benefits compared to other materials. In general terms, people h... read more

While the ‘solid’ con rod – that is, one with no joint at the big end – is very attractive from an engineering point of view, it relies on the use of an assembled crankshaft, as in a crankshaft that is a multi-piece assembly. ... read more

We have looked at and discussed several ways in which split con rods are machined on their joint faces. When they are split, there is a requirement for the surfaces to be accurately machined so that the faces are perfectly parallel, and that the plan... read more

Stud and nut, or a bolt?

Thursday, September 27, 2012
Comments (2)

As most race engines are now of the four-stroke multi-cylinder variety, the vast majority of con rods designed and manufactured for racing are of the split type. This means having a reliable means of holding the two parts of the rod together with suf... read more

Thrust face design - part 2

Monday, August 13, 2012
Comments (3)

The previous article on thrust face design of con rods was published more than a year ago. In this belated follow-up, we will look at the reasons why certain features are employed. One problem with thrust bearings is the fact that, in their simplest... read more

The effect of con rod length

Tuesday, July 03, 2012
Comments (4)

Con rods are part of the fundamental mechanism at the heart of almost every race engine in the world, and there is little to make me think that this is about to change. In dealing with the forces exerted on adjacent components by a con rod, we tend t... read more
