A method for controlling an engine having a cylinder includes sensing cylinder pressure; comparing the cylinder pressure to a pressure threshold; and adjusting an engine control parameter when the cylinder pressure exceeds the pressure threshold. A system for controlling engine operation is also provided. nkshaft axis at a lower end of said cylinder block, said cylinder block being inclined so that said cylinder bore extends upwardly from said crankshaft axis toward the vehicle wall, a cylinder head having a lower surface positioned in confronting relation to said cylinder bore, said lower surface cooperating with said cylinder bore and said piston to form a combustion chamber, a pair of cam shafts journalled for rotation in said cylinder head about cam shaft axes parallel to said crankshaft axis, each of said cam shafts being journalled by a split bearing arrangement comprised of a plurality of bearing halves mating along respective bearing surfaces, said respective bearing surfaces being parallel to and spaced from each other, said cam shaft axes being disposed on opposite sides of a plane containing said crankshaft axis and the axis of said cylinder bore, the distance between said cylinder head lower surface and the bearing surface of the cam shaft closest to the vehicle wall being substantially less than the distance between said cylinder head lower surface and the other of said cam shafts. 13. A cylinder head arrangement as set forth in claim 12, wherein the cam shaft having the other of said cam shaft axes carries a first sprocket adapted to be driven directly from the crankshaft and a second sprocket for driving a third sprocket fixed to the remaining camshaft. 14. A cylinder head arrangement as set forth in claim 13, wherein the first sprocket has a larger diameter than the third and second sprockets. 15. An internal combustion engine as set forth in claim 12, wherein the cam shaft closest to the vehicle wall is journalled by a bearing surface formed by the cylinder head and a first bearing cap affixed thereto. 16. An internal combustion engine as set forth in claim 15, wherein the cam shaft having the other axis is journalled by a bearing surface formed by an intermediate member fixed to the cylinder head and a second bearing cap affixed to at least one of said intermediate member and said cylinder head. 17. An internal combustion engine as set forth in claim 16, wherein the second bearing cap is affixed to both said intermediate member and said cylinder head. 18. An internal combustion engine as set forth in claim 16, wherein the intermediate member and the first bearing cap are integrally connected. 19. An internal combustion engine as set forth in claim 18, wherein a first short threaded fastener affixes the first and second beating caps together and a second, longer threaded fastener affixes the first and second bearing caps to the cylinder head. 20. An internal combustion engine as set forth in claim 12, wherein the cylinder block has a pair of cylinder banks arranged in a V configuration and the cylinder bore is formed in the cylinder bank closest to the vehicle wall.
