Information AboutUndersquare |
|
Undersquare engines are typically shorter in length, but heavier and taller than equivalent oversquare ones, which is one of the reasons why this type of engine is not generally used. Many British automobile companies used undersquare designs through the 1950s, largely because of a motor tax system that taxed cars by their cylinder bore. Therefore, many of the most famous cars of that era use this design. This includes the Austin A-Series Engine and many Nissan derivatives. Willys also used mostly undersquare engines, in fact the L- and F-134 engines, with their fairly small 3.125 inch bore and outrageous 4.375 inch stroke, are probably the most undersquare engines ever built. Nowadays, undersquare engines tend to be quite rare, but this form of engine is still used in some aplications. For example, a modern 8.4 liter Valmet 645 Inline-6 tractor Diesel Engine is a longstroke/undersquare engine, but has an Output of over 300 Horsepower (224 kW) with Turbocharger and Intercooler .
