Join a pre- oil feed pump, first start the pre- oil feed pump before an engine is started, makes the machine oil for being full of certain pressure in lubricating system,
This can accomplish that engine start oil pressure settling time is 0, and effect is fine.But this needs to increase additional oil pump, connection
The arrangements such as pipeline and control system etc., cost increases, while also being limited by arrangement space.
Fig. 2 is existing there are two the schematic diagram that check valve scheme engine lubrication system circulates, in oil cooler and
Oil filter both ends increase check valve, prevent the machine oil inside oil cooler and oil filter from existing when engine is shut down
The dirty oil return bottom case of gravity.This method, which can be reduced largely, starts oil pressure settling time, but machine is cold and machine filter
Arrangement space is limited, causes check valve size smaller, and flow resistance is larger, while check valve is in lubricating system high-pressure section, is easy
Damage.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art
Technology.
