A DOHC engine of the V-type has two cylinder heads each detachably secured to a cylinder block. A crank shaft on the block drives two intermediate shafts, one on each cylinder head, by means of an endless flexible element. An additional flexible endless element is provided in each cylinder head to drive two cam shafts from the intermediate shaft on that cylinder head. Each endless flexible element together with its toothed pulleys or sprockets and its timing belt or chain is described as a wrap-around transmission.
