Piston pins - material choices

[email protected]
Piston pins play a vital, literally pivotal, role in the reciprocating internal combustion engine. Mechanically they are an extremely simple component and, in their most basic form, could be a simple, short length of solid bar. Indeed, many production piston pins are not far removed from this simplest interpretation, being a very plain steel thick-walled cylinder. Racing pins are generally more complex than production car pins, as we wish to reduce mass to an absolute minimum and are less...

Abrasive flow machining

[email protected]
Race engines are characterised by high levels of output, and are generally considered to be low in mass. Engineers spend a great deal of time, and companies spend a great deal of money, in trying to create ever-lighter components. Light components lead to lower forces for a given level of acceleration, and therefore generally lead to lower friction. Such pursuit of minimum mass in engine components leads us to produce evermore complex machined parts, and new manufacturing methods will soon...

Test systems are only as good as the instrumentation used to measure and record data; without the ability to undertake accurate measurements, reliable testing cannot be conducted. However, as test beds increase in complexity, so does the volume of data generated by their sensors, making rapid interpretation of results difficult without efficient data management and analysis systems. Generally speaking, most dynamometer manufacturers will supply sensors and a data management interface with...

WRC differentials

[email protected]
The differential is one of the most important components in a modern rally car, contributing significantly to its performance potential. This impact is in terms of actual grip and, more important, the feel the differential affords the driver in order to judge available grip, allowing them to extract maximum performance from a given set-up. With the simplification of the technology allowed now in the WRC, teams are limited to using purely mechanical systems, but this was not always the...

The effect of valve size

[email protected]

There can be little doubt that the flow bench is a useful piece of equipment. They can be found everywhere, from the workshops of those who tinker with engines for a hobby to some of the top engine manufacturers in the world. Those with large financial resources and great faith in CFD can perhaps manage well enough without a flow bench - indeed, CFD can tell us much more about port flows than a flow bench ever could. Both these tools are excellent in their own way. Anyone with a little...
