The invention relates to a crank shaft of a two-cylinder diesel engine, comprising two rod shaft journals, three main shaft journals, four counter-balances and a back-end output flange which are formed in an integrated manner; wherein, the two rod shaft journals are arranged by a 360-degree crankshaft, thus changing the traditional arrangement by 180-degree included angle; the two rod shaft journals positioned in the front and the back of the crank shaft is communicated with the adjacent main shaft journals respectively by a slanting oil hole; the four counter-balances are positioned between the main shaft journals and the rod shaft journals; each counter-balance is of a sector structure; the crankshaft of the two-cylinder diesel engine not only reduces vibration of the two-cylinder diesel engine but also solves the problem of rhythmed impact of relatively long air exhaust interval on a turbocharger, reduces noise of the diesel engine, improves comfort of the engine while reducing friction force, centrifugal
