Abstract
A timing transmission mechanism (T) in an engine is formed of a chain transmission system (C) that is formed from a drive sprocket () mounted on a crankshaft (), a driven sprocket () mounted on a pump input shaft () of a high pressure fuel pump (P), and a chain () wound around the drive sprocket () and the driven sprocket (); and a gear transmission system (G) that is formed from a drive gear () mounted on the pump input shaft () coaxially with the driven sprocket () and a driven gear () mounted on a camshaft () and meshing with the drive gear (). This enables a timing transmission mechanism to be provided that can increase the degree of freedom in layout of the high pressure fuel pump without causing any increase in the number of components, the weight, or the backlash.
