CYLINDER BLOCK

Structure
• The cylinder block is made of aluminum alloy, which is cast with the cast iron liner, improving heat radiation and
decreasing weight.
• The cylinder block is a deep skirt type and forms the ladder frame structure with the integrated main bearing
cap. The water jacket of the cylinder block is a closed deck type. Its higher rigidity reduces vibration and noise.
• The cylinder block has the oil separator cover on the opposite side of the fresh air intake, the PCV (positive
crankcase ventilation) valve and the oil separator function with an part for installing the PCV valve, to improve
blow-by gas ventilation efficiency.
• The tab for alignment, used to install the upper main journal and the lower main bearing, has been
decommissioned.
• The main bearing cap bolt is a plastic region tightening bolt, which is to be tightened in two motions. It insures
a stable ais during tightening.
