Comments (1)

At present, exhausts occupy a strange position in Formula One engine development and are treated very differently in the regulations from most components that make up these highly specialised engines. Along with the snorkel (air horn), they are the ... read more

Now don't get me wrong, I like to think of myself as open to new ideas and suggestions as the next man, and indeed throughout my working life the programmes and projects I have been associated with would at least demonstrate that fact. But if you had... read more

Many of us will be familiar with nitriding as a method of providing a hard wear-resistant surface on some engine components. An additional benefit is that the surface is put into a state of residual compressive stress by treatment. The benefit of doi... read more

As a power unit engineer I must admit I still think in terms of engine dynos. In absorbing the power produced directly off the engine crankshaft - or, perhaps better still, a suitably designed PTO (Power Take Off) - this seems to me the easiest way t... read more
