PROBLEM TO BE SOLVED: To make both compatible in reliability and controllability of feedback control. SOLUTION: This V-type engine becomes an unequal interval in a combustion interval in the same bank without becoming alternate in combustion order in right-left banks, and has a phase adjusting mechanism, a cam position signal generating means for generating a plurality of cam position signals at an equal interval per one rotation of a camshaft by synchronizing with rotation of the camshaft, a valve timing detecting means for detecting the actual valve timing based on this cam position signal, a feedback control means for controlling a command value imparted to the phase adjusting mechanism by making a feedback process so that the actual valve timing coincides with the target valve timing, and signal number changing means S34-S38 for changing the number of cam position signals used for detecting the actual valve timing among the plurality of cam position signals per one rotation of the camshaft in response to an operation condition of the engine.
