Motor V12 of a Ferrari 250TR Spyder of 1961.
In automotive mechanics, a V12 engine is one that has two banks of 6 cylinders with crankcase and crankshaft common to both, generally with an opening of 60º or 120º between them.
HistoryThe first V12 was manufactured in 1904 by Ailsa Craig. It had a displacement of 23000 cc and a performance of 150 HP at 1000 rpm. Description
Each bank is basically a block of 6 cylinders in line, configuration that is characterized by its fineness of operation, virtually absent of vibrations, so it does not need balancing shafts. Therefore, a V12 engine, with the banks of cylinders at 60º, 120º or even 180º (configuration used in the past, for example, Ferrari, in the Testarossa engine of 1984 and in that of its successors 512TR and F512M) characterized by its even greater fineness of operation because the explosions of the cylinders occur in much shorter time intervals, producing one every 60º of rotation of the crankshaft in a four-stroke engine, which also enables the operation of the engine at very few revolutions (less than 1500 rpm) without any vibrations or tendency to stall. This is why they are very used engines in luxury vehicles.
