In terms of engine development leading materials development, modern gas turbines are an excellent example. Since the days of Sir Frank Whittle, these engines have been able to progress only through parallel development of materials that are capable ... read more

Dirty talk

It's an interesting but nevertheless slightly surprising fact that the vast majority of premature bearing failures in engines are as a direct consequence of the presence of dirt. Such were the conclusions of a report I read recently, and while lack o... read more

Camshaft care

Thursday, December 15, 2011
Comments (0)

It is sometimes easy to forget that after all the efforts a cam manufacturer makes in producing his products, the greatest cause of failure is not in the installation or its timing but in the first few seconds and minutes of its active life. It's a ... read more

Many of the applications discussed in the RET-Monitor articles where thermal barrier coatings are concerned have been on the subject of exhausts. Thermal barrier coatings here have the aim of reducing radiated heat, although in some cases a benefit o... read more

Bushless small ends

Thursday, December 15, 2011
Comments (1)

When we come to describe a 'traditional' racecar con rod for a four-stroke engine, we would imagine a split rod with a bushed small end (or at least many of us would). The bushed small end has been with us for many decades, but the bushless steel con... read more

Aerodynamic counterweights

Thursday, December 15, 2011
Comments (2)

In the search for increased performance, the common direction of engine development has been to increase engine speed incrementally. While this trend is somewhat on the wane - owing to various regulations such as absolute rpm limits as in Formula One... read more

As a young man (many years ago), although my spelling was never entirely satisfactory, the subject of mathematics never daunted me. Matrix manipulations, Laplace transforms and complex differential equations were as meat and drink to me as I endeavou... read more

The lower liner seal

Thursday, December 15, 2011
Comments (1)

Of the many gaskets and seals in an engine, probably the most annoying and terrifying in equal measure, when it fails, is that at the mid or lower liner. On dry-liner engines this doesn't exist of course, so the product developers can sleep soundly a... read more

Taking the heat

Thursday, December 15, 2011
Comments (2)

In any internal combustion engine, the design or configuration of the cylinder or its liner is of critical concern. Exposed to the full effect of combustion at its upper part, which falls as we go down the cylinder, the component has to be as light a... read more
