This is the first occasion where we have covered the use of copper alloys, and we shall look briefly at their main applications. Throughout the article the word 'bronze' is used: technically this is a copper alloyed with tin, among other things but b... read more

In 2009, and to much fanfare, Formula One ushered in a new technological development that should have improved the racing spectacle and gone some way to placating those environmentalists who see motorsport as the enemy. In both these regards, the int... read more

Lead free bearing(s) fit

In another article in this issue of RET-Monitor, I have given what I hope is an insight into crankcase main bearing split design (keyword: heads-blocks). Background is the accuracy of the main bearing split line geometry, primarily focused on the rou... read more

Machine backlash

Friday, July 02, 2010
Comments (0)

One of the biggest issues with any machine tool, camshaft grinders included, is that of axis backlash. Defined as the loss of motion when the machine's axis, either rotational or linear, reverses, it can have a major influence on the precision of the... read more

Oil-shedding coatings

There is wide agreement among racing engine manufacturers and builders that the source of much friction in the racing engine comes from the crankcase. These losses are not entirely due to the amount of lubricant in the crankcase, as I can attest from... read more

Can we manage without big-end bearings?

Comments (1)

The big-end bearing shells that we find in almost all four-stroke racing engines are an item made with great precision. They are generally 'graded' and as such are available in thickness grades which have a range of only a few microns. Moreover, thei... read more

The fatigue behaviour of a crankshaft is dictated by the service loads it is expected to cope with, its manufacture and its geometry. In numerous articles concerning crankshafts, surface treatments and materials, RET-Monitor has stressed the critical... read more

Fractured accuracy

Friday, July 02, 2010
Comments (0)

As can be seen from earlier articles in RET-Monitor on race engine block material, a trend can be seen towards Compacted Graphite Iron as a crankcase material. It has been used occasionally in the past on highly loaded motorsport applications but it ... read more

Comments (0)

Last time we looked at ways of producing high-quality cylinder bores. Needless to say, the thinking and methods used might seem extreme to some or insufficient to others. In all this, however, we must always remember that it is not the shape or degre... read more

Turbo oil seals

Friday, July 02, 2010
Comments (2)

If a shaft spinning at 20,000 rpm can pose a sealing problem then what about one doing 120,000 rpm or even, dare I say it, 240,000 rpm? A simple enough question, you might say, but before answering it we need to understand the application and the des... read more
