DEVICE FOR CONTROLLING MULTI-CYLINDER ENGINE

A device for controlling a multi-cylinder engine is provided with a combustion chamber (19) to which an intake port (16) and an intake port (17) are connected, wherein: the device for controlling a multi-cylinder engine is provided with an intake-side variable valve mechanism (71) for controlling the lift timing of intake valves (21a, 21b) of the intake port (16), an exhaust-side variable valve mechanism (72) for controlling the lift timing of an exhaust valve (22a), and an exhaust-side valve train mechanism (73) for driving an exhaust valve (22b) at a fixed timing. When cylinder deactivationis performed in a low load/low rotation operation region, the exhaust valve (22a) is opened by the exhaust-side variable valve mechanism (72) while a piston (14) in a cylinder (18) subjected to cylinder deactivation is descending. 种多气缸发动机的控制装置，具备与进气端口(16)以及进气端口(17)连接的燃烧室(19)，其具备用于对进气端口(16)的进气门(21a、21b)的提升定时进行控制的进气侧可变气门机构(71)、用于对排气门(22a)的提升定时进行控制的排气侧可变气门机构(72)、以及在固定的定时驱动排气门(22b)的排气侧气门机构(73)，当在低负载低旋转运转区域中进行气缸停止的情况下，在进行气缸停止的
