CYLINDER BLOCK CONSTRUCTION [LF, L3]

id0110001005a2

• The cylinder block is made of aluminum alloy cast with an iron liner, improving heat radiation and decreasing weight.

• The cylinder block is a deep, skirt-type composed of an integrated main bearing cap together with a ladder frame structure. The water jacket of the cylinder block is a closed deck type. Its higher rigidity reduces vibration and noise.

• To improve blow-by gas ventilation efficiency the cylinder block has an oil separator cover on the opposite side of the fresh air intake, and a PCV (positive crankcase ventilation) valve with an oil separator function having the installation on area for the PCV valve.

• There is no positioning tab where the upper main journal and the lower main bearing are installed.

• The main bearing cap bolts are plastic region tightening bolts tightened in two steps to insure tightening stability.

• The service hole for installing the SST, which is used for detecting the No.1 cylinder TDC position, is located at the right side of the cylinder block. The TDC position can be detected when the SST edge touches the cutting surface of the No.1 counter weight.
