Diesel engine and method of controlling the same

A diesel engine includes a cylinder section (10) and also includes a shared hydraulic source (13A) for driving at least one of a fuel jet system (11) and an exhaust valve system (12), and a boost section (13B). Based on a boost piston lift signal for each cylinder, which is output from the boost section (13B), the drive time of an electromagnetic valve relating to the fuel jet system (11) for each cylinder in the cylinder section (10) is adjusted.
