Embodiment 1

[0010] For a certain type of diesel engine, the running-in time is 45 minutes. Add reinforcing agent to the running-in oil, the ratio of antimony dialkyldithiocarbamate to zinc dialkyldithiophosphate is 0.42, the amount of reinforcing agent added is 5%, and the running-in time of diesel engine is shortened Break-in time was reduced by 22% to 35 minutes.

Embodiment 2

[0012] For a certain type of diesel engine, the running-in time is 48 minutes. Add reinforcing agent to the running-in oil, the ratio of antimony dialkyldithiocarbamate to zinc dialkyldithiophosphate is 0.55, the amount of reinforcing agent added is 7%, and the running-in time is reduced to 33 minutes , The break-in time has been shortened by 30%.

Embodiment 3

[0014] For a certain type of diesel engine, the running-in time is 43 minutes. Add reinforcing agent to the running-in oil, the ratio of antimony dialkyldithiocarbamate to zinc dialkyldithiophosphate is 0.25, the amount of reinforcing agent added is 2%, and the running-in time of diesel engine is shortened Break-in time was reduced by 7% to 40 minutes.

Abstract

The invention discloses a diesel engine running-in oil reinforcing agent, wherein antimony dialkyl-dithiocarbamate and zinc dialkyldithiophosphate are compounded in a compounding ratio of 0.2-0.8 and then added to base oil for use. The diesel engine running-in oil reinforcing agent provided in the invention is capable of effectively improving the performance of the diesel engine running-in oil. After the reinforcing agent is added to the diesel engine running-in oil, the running-in time of the diesel engine can be shortened. Besides, the diesel engine running-in oil reinforcing agent is rational in raw material mixing, simple in production process, and thereby can be widely applied to the existing diesel engine running-in oil.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a running-in oil product. Background technique [0002] The diesel engine production process includes a diesel engine running-in process, shortening the diesel engine running-in time can help diesel engine manufacturers save fuel costs, thereby reducing production costs. In order to shorten the running-in time of diesel engines, diesel engines use diesel engine running-in oil for running-in. The existing diesel engine running-in oil mainly adds zinc dialkyldithiophosphate (ZDDP), and at the same time adds a small amount of dispersant such as: polyisobutylene succinimide, etc., and a small amount of antifoaming agent such as: methyl silicone oil, etc. [0003] The use of zinc dialkyldithiophosphate (ZDDP) in the running-in oil of diesel engines can reduce the running-in time of diesel engines, but it is difficult to meet the requirement of further reducing the running-in time.
