Abstract
The camshaft of a turbocharged internal combustion engine is designed to account for the distance between each cylinder and the preceding cylinder in firing order. The camshaft is designed so that the exhaust valve of, say, cylinder number 4 opens at a sufficiently early time that the pressure pulse from opening of the preceding cylinder, say cylinder number 3, arrives at cylinder number 4 when cylinder number 4 is at a predetermined relationship to its top dead center position, where cylinder number 4 immediately follows cylinder number 3 in firing order. The angle at which an exhaust valve cam precedes its top dead center position is determined from the distance to the preceding cylinder through the exhaust system, the speed of sound, the engine speed at which optimization is desired, and the predetermined relationship.
