Sveiki visapkārt!

Vai kads, piem. cien Crankshaft, var pareizi izskaidrot definīciju par short block vai big block, Magnum dzinējam, ka to pareizi izprast?

Small block and Big Block are relative terms to describe the overall dimensions of the engine. It is a popular misconception that the engine's displacement determines its classification as a big block or small block. For example, Chevy's 396ci engine is considered a big block because like all chevy big blocks, the bore diameters are wide, the strokes are short, the heads are relatively big, and the "V" formation is cast at a fairly obtuse angle. However, Chevy's Corvette LS7 engine, which is 427ci, is classified as a small block due to being more dimensionally compact in comparison to the 396. The LS7 has similar dimensions to the LS1 engine which is a 350 and the reason it has such high displacement is because of a very stroked out crankshaft.

The uses for both types of motors are more or less intertwined. Big blocks produce more brute torque than small blocks, so they would be more commonly found in large trucks, or trucks designed to be heavy duty workhorses. Small blocks can do the same, except they are less efficient for such applications. They are more used in cars, small to medium duty trucks, and once in a great while, heavy trucks.

big, small, shorty, long - kaaju var nolauzt tais jenjkju tekstos. Man shkjiet - iet runa par virzulja gaajuiena attieciibu pret virzulja diametru. Ja diametrs liels, gaajiens mazs - short block, diametrs saliidzinoshi neliels, gaajiens garsh - big block. Kaa reizee tie big block arii ar lielaakaam klokjeneem, mazaakiem apgriezieniem, lielaaku torgue - griezes momentu.

Kā reiz ir tieši otrādāk - big block - liels virzuļa diametrs, attiecīgi liela izmēra galvas, lasīt iepriekš - "Chevy's 396ci engine is considered a big block because like all chevy big blocks, the bore diameters are wide, the strokes are short, the heads are relatively big"

Es tachu teicu - tais tekstos var kaajas aplauzt! Tieshi torgue lielaaks ir motoriem ar relatiivi garaaku virzulja gaajienu un liidz ar to lielaaku klokjenes diametru - t.i. -lielaaks attaalums no pamatkaklinja centra liidz klanja apaksheejaa gultnja centram - lielaaks griezes moments. Tai tekstaa ir sajaukti big,short,small un nezinkas veel! Jo dzineejiem ar iisaaku virzulja gaajienu attieciibaa pret virzulja diametru nevar buut lielaaks torgue kaa dzineejiem ar garaaku gaajienu pie taada pat virzulja diametra!
