There is little doubt that, in many ways, steels have improved markedly in recent years. Fatigue properties in particular have seen a large improvement owing to better steel cleanliness. However, it is not only the cleanliness that affects fatigue be... read more

In 1949, British industrialist Tony Vandervell bought a contemporary Ferrari Grand Prix car - not a straightforward exercise in the aftermath of World War II, as it required an import licence, while the export of currency to Italy required special pe... read more

Tight times!

Thursday, March 31, 2011
Comments (0)

The most common aspiration of just about all power unit engineers is that of greater engine performance. Better fuel economy, improved toxic emissions or simply better torque over a wider range of operating speeds - much of it but certainly not all -... read more

Pistons are part of the fundamental mechanism of most internal combustion engines, and are certainly very widely employed in racing. While roadcar producers still persist in development of the rotary engine concept, it has been pretty much abandoned ... read more

Avoiding the need to stagger

After inventing the internal combustion engine, it became clear that man always wanted more power, not only for racing and record-breaking, but also for his road vehicles. Today we have road-going production motorcycles that are more powerful than th... read more

One of the functions of a crankshaft, besides playing its fundamental part in an engine's basic mechanism, is to transfer oil, especially to the con rod big-end bearings. In some cases, where all main bearings are directly fed from the main oil galle... read more

The wiring harness

If the ECU can somehow be considered as the brain of the engine then I guess the wiring harness is roughly equivalent to the rest of the nervous system. In humans and other animals, receptors in the skin send impulses to the brain via dendrites and t... read more

The monobloc engine

Comments (3)

Isn't it strange to think that what we regard today as being 'obvious' wasn't quite so obvious in the early days of race engine design. Take the head gasket, for instance. Today's young engineers are almost conditioned to think in terms of separate c... read more

Deformed head

Comments (0)

It's an obvious thing to say, perhaps, but while an engine has to contain lots of moving components in order to function properly, it also contains many parts that are not intended to move at all. For example, cylinder heads and crankcases are not in... read more
