解决办法：在气温较低时，应使用粘稠度低一点的机油。还有就是每台发动机都配有预热装置，打火之前应多预热几次。

The solution: you should use lower viscosity of the oil when the temperatuer. And every engine shoule be equipped with preheating device, should preheat several times before ignion.

这是因为，合理的预热能够协助机油在发动机部件与部件之间构成“油膜”，然后削减发动机部件磨损。

This is because a proper warm-up can assist the oil to form an oil film between the engine parts and components, and then reduce the wear of engine parts.

不管是什么，如果它非常重要，你应该看着这个工具盒，以及将要工作运行的发动机，没有预热的发动机不会好好工作。

Whatever it is, if it's really important, you owe it to yourself to look at this toolbox and the engine that it's going to work on, and no engine works well without being warmed up.
