•  The cylinder block forms the cylinder and crankcase.

•  The cylinder block consists of the upper cylinder block and lower cylinder block.

•  The cylinder block is an open deck type with excellent cooling performance.

•  The lightweight cylinder block is made of aluminum alloy with excellent heat dispersion.

•  With the adoption of the lower cylinder block, the coupling rigidity of the transaxle and support rigidity of the crankshaft have been improved reducing engine vibration.

•  The oil separator function is set to the upper cylinder block, enhancing ventilation of the blow-by gas.
