Cylinder barrel increases honing technique after fine finishing, cylinder barrel after honing, the cylindricity of its internal surface can reach 0.0065mm, highi degree of accuracy like this, makes piston can be freely movable in cylinder barrel, can not because of the irregular clamping stagnation causing piston of cylinder barrel shape, cylinder barrel internal surface after honing simultaneously there will be the reticulate pattern of regular shape, in engine operation process, the existence of reticulate pattern is beneficial to formation oil film, and piston is better lubricated in the process of motion.
Cylinder cap mounting plane be cylinder block and cylinder head in conjunction with plane, have higher planeness and surface roughness requirements, middlely place head gasket, the seal of firing chamber, water channel and oil duct after compression, can be ensured.
Oil sump mounting plane is the plane of installing oil sump, cylinder block adopts all-in-one-piece design, no longer be provided with crankcase, decrease the trueness error that traditional cylinder block and crankcase assemble, the bottom surface of cylinder block is directly as the mounting plane of oil sump, make final assembly technique more simple, also reduce because sealing problem causes the risk of oil leakage.
Timing chain cover mounting plane be cylinder block and timing chain cover in conjunction with plane, have higher planeness and surface roughness requirements equally, middlely play glue, to ensure the seal of timing chain room.
Gearbox front case is installed in the rear end of gearbox mounting plane, the stiffening rib that many thickness are 8mm is provided with between gearbox mounting plane and spindle hole, ensure that the structural strength of cylinder block rear end is enough to support the load that causes of gearbox, also improve the rigidity of cylinder block rear end simultaneously, reduce the distortion caused because of load of cylinder block.
Cylinder block dividing plate mounting plane is for installing cylinder body dividing plate, the sealing channel that cylinder body dividing plate and cylinder block are formed is the gas channel of crankcase ventilation system, upper cylinder head, lower logical crankcase, for the fuel-air mixture in crankcase being transported in the middle of the deaerator in valve mechanism cover, finally isolate oil gas and water vapour, the design of this integrated morphology decreases the pipeline on motor, there is the advantage of compact structure, meanwhile, irregular gas channel design can reach preliminary effect of filtering fuel-air mixture.
Main bearing bore is for placing crankshaft main journal, and the position be connected with cylinder block in main bearing bore arranges stiffening rib, to ensure the load that cylinder block has enough intensity and causes to support crankshaft rotating.
Spindle hole center and cylinder holes center have the throw of eccentric of 8mm, and when piston moves in cylinder holes, frictional force is less, and engine mechanical loss is less, thus improves the peak output of motor.
