•  The cylinder block forms the cylinder and crankcase.

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

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

•  The lower cylinder block functions as the main bearing cap. The coupling rigidity of the transmission and support rigidity of the crankshaft have been improved, reducing engine vibration.

•  The engine oil is separated from the blow-by gas by installing an oil separator to the upper cylinder block.
