Abstract
An engine method, comprising turning off a second cylinder group in response to engine load falling below a first threshold, the second cylinder group including a first outer most cylinder and its immediately adjacent cylinder and turning on the second cylinder group in response to engine load raising above a second threshold and operating a first cylinder group constantly throughout engine operation; the first cylinder group including a second outer most cylinder and its immediately adjacent cylinder. By this method, engine efficiency may increase during partial load operating conditions from low engine loads.
