The deep skirt cast aluminum cylinder block is an inline configuration. Thin wall, interference fit cast iron liners provide optimum weight, cylinder bore roundness and robustness. The low volume coolant jacket gives good warm up times.
The cylinder block is a cross flow design with:
- The coolant inlet to the cylinder head on the air inlet side
- And the coolant outlet from the cylinder head on the exhaust side.
Oil from the cylinder head drains back to the oil pan through open apertures. The 10 apertures are located on each side of the cylinder block between each cylinder.
A cast aluminum alloy, structural windage tray is bolted to the bottom of the cylinder block:
- To improve the cylinder block stiffness.
- To minimize Noise, Vibration and Harshness (NVH).
- To help reduce oil foaming.
Various machining ports in the cylinder block are sealed with cup plugs and threaded plugs. Removal of these is not necessary for service procedures.
There is a front cover and a rear cover on the engine. Both covers are fixed to the cylinder block by bolts and sealed to the cylinder block with RTV sealant. Both covers contain a flat surface for the oil seal.
