Abstract: PURPOSE: A camshaft driving device of a V type engine is provided to stop operation of one of two banks when a V type engine is operated at a low speed and in a low load by connecting left and right camshaft sprockets with a crankshaft sprocket. CONSTITUTION: When an engine is operated at a low speed and in a low load, an ECU(Electronic Control Unit)(13) operates a solenoid valve(12) to open an oil supply passage(7) with response to a signal transmitted from a TPS(Throttle Position Sensor)(15). The oil delivered from an oil pump(11) flows into an oil pressure chamber(5) by passing through a groove(10) of a camshaft support unit(8) and the oil supply passage. As oil supply pressure is higher than the elasticity of a spring(14), the spring is compressed by a piston(6). The piston is lifted down and a pin(3) is received in a camshaft body. If the pin is displaced from a fixing groove(4), a camshaft sprocket(2) idles and the camshaft stops rotating. When the camshaft stops, intake and exhaust valves stop and so does a corresponding bank. Simply, the other bank forming a V shape is driven. Then, the output of an engine is decreased and fuel consumption is reduced.
