Abstract

The invention relates to a pre-lubricating device for starting an engine and belongs to the field of auxiliary devices for automobiles. The pre-lubricating device for starting the engine solves the problem of cold start of an automobile engine and particularly solves the problem of dry friction in the low-temperature cold starting process. A hot oil area groove (2) is formed in an oil pan (1), an electric heater is installed in the oil pan (1), oil from an oil outlet of the oil pan (1) enters a main oil way (17) of an engine (23) sequentially through a first check valve (11), an oil outlet pipe (12), a pre-lubricating engine oil pump (13), a communicating pipe (14), an engine oil filter (8), an oil inlet pipe (15) and a second check valve (16), and then a pre-lubricating engine oil delivery system is formed. Meanwhile, a corresponding device is arranged, the heating device and a base plate (18) are assembled into a whole, and an electronic control panel (19) is installed on the base plate (18). The pre-lubricating device for starting the engine can guarantee pre-lubrication in the starting process of the automobile engine, dry friction is overcome, and the pre-lubricating device for starting the engine is particularly suitable for pre-lubricating in the cold starting process of the automobile engine at low temperature and starting the engine (23) and convenient to selectively use. The pre-lubricating device for starting the engine is capable of saving energy, environmentally friendly, convenient to manufacture in a standardized mode and operate, and easy to install, adjust and maintain.

Description

technical field [0001] The invention belongs to the field of automobile auxiliary devices, and relates to an engine starting pre-lubrication device. Background technique [0002] In the prior art, when the automobile engine is cold started, almost all the lubricating oil supplied to the friction pair in the previous working state fell back into the oil pan (hereinafter referred to as the oil pan), so the main friction pair was in dry friction or critical friction State, this kind of dry friction (friction between metal and metal without lubricating oil) is ubiquitous, and some data show that 80% of engine wear comes from dry friction. Dry friction results in increased fuel and oil consumption, increased harmful exhaust emissions and ultimately premature engine failure. At low temperature in winter, especially in the environment of tens of degrees below zero, the dry friction of the engine caused by cold start is more serious than that caused by cold start in the general sen...

Dry friction results in increased fuel and oil consumption, increased harmful exhaust emissions and ultimately premature engine failure

At low temperature in winter, especially in the environment of tens of degrees below zero, the dry friction of the engine caused by cold start is more serious than that caused by cold start in the general sense. The resistance in the cleaner is greatly increased, and it is difficult for the oil to enter the friction pairs smoothly and evenly. When the engine is started, the dry friction time will inevitably increase, the degree of wear will increase, and the engine will be difficult to start.

As far as the existing engine cold start pre-lubrication technology to solve the dry friction problem is concerned, most of them use a pre-lubrication oil pump in parallel with the original engine oil pump lubrication system to perform pre-lubrication before the engine starts. The original oil filter is The two oil pumps share the disadvantages: first, there is no independent filter, and there is no heating in the pre-lubrication oil delivery system, so the flow of pre-lubrication oil is not smooth, or there is only a preheating device in the oil pan of the engine , its preheating function is very limited. First, the heating power is limited. Second, the total amount of oil in the oil chassis of a large vehicle is more than 30 liters. It cannot be collected in the oil chassis, so the heat is difficult to concentrate, so it is difficult to ensure the normal operation of the pre-lubrication oil pump, and it is also impossible to ensure the smoothness of the pre-lubrication circulation circuit. It is not suitable for pre-lubrication of the cold start of the engine at low temperature in winter. 1. The integrity is poor, the components are scattered, and it is not easy to install, detect, maintain and replace. Thirdly, some strive to be convenient to use, and their electronic control systems are closely related to the original engine starting system, resulting in more electronic control nodes and changing the original car design. , but added the unreliable factors of the original engine starting system and pre-lubrication system, which is not conducive to user acceptance and use
