If you thought it was only race engine manufacturers who are paranoid about friction at the crankshaft seal, think again. The inexorable push towards ever lower CO2 emissions - better fuel economy to you and me - is making many an original equipment ... read more

Diesel fuel is extremely popular for automotive use, particularly in Europe where, for some manufacturers, diesel vehicles account for more than 50% of sales. Part of the reason is that, in some countries, diesel fuel is much cheaper than petrol (ga... read more

Comments (1)

Continuing the discussion of wire thread inserts in previous articles, this month I'll consider 'solid' types of insert. There are at least two varieties of 'solid' inserts in common use, and these are used mainly for repairs and, less often, in situ... read more

Comments (0)

Perhaps the most common word used today in engineering is 'optimise.' Now, my memory may be a little bit selective, but until about 20 years ago the word was rarely used. But I have a theory. In the past, engineers were probably far too busy concentr... read more
