请把这些翻译成中文,翻译好的追加100分.谢谢各位了V-type engines have two cylinders operating off each throw.The two end throws are on one plane offset 180 degrees apart .The two center throws are on another common plane,which is also 180 degrees apart.The two planes are offset 90 degrees from each other.
In-line six-cylinder engines have throws a-ranged on three planes.There are two throws on each plane that are in line with each other.Three planes are arranged 120 degrees apart.
V-type twelve-cylinder engines have throw arrangements like the in-line six-cylinder engine.The difference is that each throw accepts two-engine cylinders.
V-type six-cylinder engines have three throws at 120-degree intervals.Each throw accepts two-engine cylinders.
The crankshaft is supported in the crankcase and rotates in the main bearings.The connecting rods are supported on the crankshaft by the rod bearings.Crankshaft bearings are made as precision inserts that consist of a hard shell of bronze with lining of antifrictional metal or bearing alloy.Bearings must be able to support the crankshaft rotation and deliver power stroke thrust under the most adverse conditions.
The crankshaft rotates in the MAIN BEARINGS located at both ends of crankshaft and at certain intermediate points.The upper halves of the bearing fit right into the crankcase and the lower halves fit into the caps that hold the crankshaft in place.These bearings often are channeled for oil distribution and may be lubricated with crankcase oil by pressure through drilled passages or by splash.Some main bearings have an integral thrust face that eliminates crankshaft end play.To prevent the loss of oil ,place the seals at both ends the crankshaft where it extends through the crankcase .When main bearings are replaced ,tighten the bearing cap to the proper tension with a torque wrench and lock them in place with a cotter pin or safety wire after they are in place .
Vibration due to imbalance is an inherent problem with a crankshaft that is made with offset throws.The weight of the throw tend is to make the crankshaft rotate elliptically.This is aggravated further by the weight along the crankshaft.One weight is placed 180 degrees away from each throw.They are called counterweights and are usually part of the crankshaft but may be a separate bolt on items on small engines.
The crankshaft has a tendency to bend slightly when subjected to tremendous thrust from the piston .This deflection of rotating member cause vibration.This vibration due to deflection is minimized by heavy crankshaft construction and sufficient support along its length by bearings.

Early manufactures of engines,because of lack of koowledge and equipment in casting techniques,were only able to produce an engine assembly having separate cylinder castings,all mounted upon crankcase.While this method is still used for some air-cooled engines,it is not really practical for a liquid-cooled engine.However,as manufacturing techniques have improved,the while construction[cylinder block and crankcase]is produced in one assembly.Cylinder block for modern liquid-cooled engines are cast as single units.求大神们准确的帮我翻译,要准确啊
