摘要： A control system for a variable-cylinder internal combustion engine, which is capable of attaining excellent fuel economy by executing a partial-cylinder operation mode as long as possible, while suppressing vibration and noise during the partial-cylinder operation mode. A control system switches the operation mode of a variable-cylinder internal combustion engine between an all-cylinder operation mode in which all of a plurality of cylinders (#1 to #3, and #4 to #6) are put in operation, and a partial-cylinder operation mode in which some (#1 to #3) of the plurality of cylinders are deactivated. During the partial-cylinder operation mode, the control system 1 calculates a degree-of-continuation parameter SDTQCSNH indicative of a degree of continuation of a state where detected load TQECMDF on the engine is within a predetermined range of load between a first reference value TQCSNH and a second reference value TQCSEH smaller than the first reference value (steps 10 to 13), and determines whether or not the operation mode should be switched to the all-cylinder operation mode, based on the degree-of-continuation parameter SDTQCSNH (step 14).
摘要翻译：一种用于可变气缸内燃机的控制系统，其能够通过在部分气缸运转模式期间抑制振动和噪声来尽可能长时间地执行部分气缸操作模式而获得优异的燃料经济性。控制系统在多缸气缸（＃1〜＃3，＃4〜＃6）全部投入运转的全气缸运转模式之间切换可变气缸内燃机的动作模式，部分气缸操作模式，其中多个气缸中的一些（＃1至＃3）被停用。在部分气缸操作模式期间，控制系统1计算指示发动机上检测到的负载TQECMDF在第一参考值TQCSNH之间的预定负载范围内的状态的持续程度的持续程度参数SDTQCSNH 和小于第一参考值的第二参考值TQCSEH（步骤10至13），并且基于继续持续参数SDTQCSNH来确定是否应将操作模式切换到全气缸操作模式（步骤 14）。
