Emvi recently shared this with other BHPians.
I have always been curious to know why are engine displacement and power output figures not a perfect number in automobiles!? Elaborating a bit further, when I say perfect I mean, from a 100cc bike to a 7.0L engined truck, neither the bike s engine is perfectly 100cc nor the truck s engine displacement is exactly 7.0L and so is the case for all the vehicles with various engine capacities. In addition to this, the power output figures throw quite interesting numbers too.
It is understandable that on occasions, manufacturers deliberately design and manufacture engines with imperfect displacement figures in order to comply with regulations that are in place in some countries/regions. For example, in India, the engine displacement for a small car shouldn t exceed 1.5L for a diesel and 1.2L for a petrol to comply with the small car tax regulations. So, invariably the engine displacement is kept below the limit at least by a cubic c
