hen the engine is working, the cylinder block withstands high heat and mechanical load. In order to make the engine
work in normal and reliable operation, the cylinder block shall be of high strength, enough rigidity, compact structure, low
weight and easy servicing.
1. Gantry structure, plus well-deployed isolating plate and reinforced rib, provide high anti-bending and anti-twisting
strength.
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 installed
and front wheel driving.
4. The cylinder block is compact. The cylinder center distance is 87.5mm. There’s the main oil passage in the cylinder
block, connecting to the oil pump, oil filter, and oil pressure sensor directly. There’s optimized layout for cooling system of
water cavity and water flow. And the servicing is easy (Fig. 15).
