Exhaust system for sideway-mounted engine

摘要

An engine has first and second cylinder rows substantially parallel to each other and is mounted sideways so that the cylinder rows are arranged side by side in the longitudinal direction of the vehicle body with the first cylinder row disposed forward of the second cylinder row. An exhaust system for the engine has first and second exhaust pipes. The first exhaust pipe is connected to the cylinders in the first cylinder row on the front side of the first cylinder row and is led rearward of the engine through a recess formed on the lower side of an oil pan of the engine which is positioned between the first and second cylinder rows. The second exhaust pipe is connected to the cylinders in the second cylinder row on the rear side of the second cylinder row, is once led forward into the recess of the oil pan and then turned rearward in the recess to extend rearward. The first and second exhaust pipes are merged into a common exhaust pipe at a junction in the rear of the engine.
