Abstract: A device for predicting energy consumption includes an obtaining unit (110), an air resistance calculating unit (140, 150), and an energy consumption predicting unit (150). The obtaining unit (110) is configured to obtain road information including traveling speed information set for each route. The air resistance calculating unit (140, 150) is configured to calculate air resistance as a calculated air resistance value by an air resistance calculation formula on the basis of the traveling speed information of the scheduled traveling route and to correct the calculated air resistance value so that the air resistance is higher according as the traveling speed along the scheduled traveling route is lower. The air resistance is caused when a vehicle travels along a scheduled traveling route. The energy consumption predicting unit (150) is configured to predict an energy consumption of the scheduled traveling route on the basis of the corrected air resistance value.

Abstract: A variable valve timing system in an engine having a rotating cam-shaft includes a timing pulley driven by the engine and a damper case rotatably fixed to the crank-shaft. A piston is movable in a space defined by the timing pulley and the damper case and has helical gears engaging helical gears of the timing pulley and damper case such that the angular position between the timing pulley and the damper case varies as the piston is moved. Movement of the piston is induced by hydraulic pressure in a pressure chamber selectively connected to hydraulic pressure by an electronically controlled solenoid valve. Engaging labyrinth grooves on the timing pulley and damper case damp rotational vibrations which would otherwise be induced by variations in the torque applied to the damper case, and so prevent undesirable movement of the piston.
