When the engine is working, the cylinder block withstands high heat and mechanical load. In order to make the enginework in normal and reliable operation, the cylinder block shall be of high strength, enough rigidity, compact structure, lowweight and easy servicing.1. Gantry structure, plus well-deployed isolating plate and reinforced rib, provide high anti-bending and anti-twistingstrength.2. It’s made of alloy casting iron, providing high strength and enough rigidity.3. Cylinder block is short in length and light in weight. These engines are suitable to the transverse mounting, front installedand front wheel driving.4. The cylinder block is compact. The cylinder center distance is 87.5mm. There’s the main oil passage in the cylinderblock, connecting to the oil pump, oil filter, and oil pressure sensor directly. There’s optimized layout for cooling system ofwater cavity and water flow. And the servicing is easy (Fig. 15).Chapter 2 Cylinder Block AssemblySection 1 Structural Characteristic of Cylinder Block110108892344 57766Fig. 15 Cylinder Block1.Oil filter compo. 2.Six.flange bolt – grade B 3.RH installation bracket 4.Positioning bush5.Oil passage screw plug 6.Dowel pin 7.Dowel pin 8.
