Abstract:
An object of the invention is to improve space efficiency, while ensuring a desired blow-by gas processing performance. As gas routes that connect a crankcase and each of intake passages, a first gas route and a second gas route connected to respective throttle upstream parts of the intake passages on the upstream side of each throttle valve for each bank, and a third gas route connected to a throttle downstream part of the intake passage for one of the banks are provided. Separators are disposed in the respective gas routes, for separating oil mist from blow-by gas. Only the first separator having a comparatively large capacity is disposed in the first bank on the side where a crankshaft rotates upward from the bottom. The second and third separators are both juxtaposed to each other in the second bank on the side where the crankshaft rotates downward from the top.
