Purpose, Function
The cylinder block forms the cylinder and crankcase.
Construction
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.
