Problems solved by technology

[0007] However, at present, the quality evaluation of engine oil mainly uses the physical and chemical indicators of engine oil, which cannot truly reflect the actual volatilization of engine oil during vehicle operation and the actual impact of volatilized engine oil on the engine, so it cannot accurately evaluate whether the engine oil is suitable for the application.

Embodiment 1

[0040] Refer to attached figure 1 , an engine oil adaptability detection device provided in an embodiment of the present invention includes an air filter (hereinafter referred to as air filter), an engine, an oil-air separation system and a second oil-air separator, and the engine includes a crankcase and an intake manifold Pipe 1, the oil-gas separation system includes a first oil-gas separator and a PCV valve, the air filter is respectively connected to the first oil-gas separator and the second oil-gas separator through pipelines, the crankcase, the first oil-gas separator The device, the PCV valve, the second oil-gas separator and the intake manifold 1 are connected in sequence.

[0041] as attached figure 2 As shown, the first oil-gas separator is a cylinder head cover integrated labyrinth oil-gas separator, and the first oil-gas separator includes a first air inlet, a first oil outlet and a first exhaust port. The incoming low-temperature air enters the first oil-air ...

Embodiment 2

[0045] A method for detecting engine oil adaptability provided by an embodiment of the present invention includes the following steps:

[0046] 1) A second oil-gas separator is connected between the oil-gas separation system of the vehicle and the intake manifold 1, the second oil-gas separator is detachable, the vehicle is a methanol vehicle, and the engine oil used by the methanol vehicle is methanol oil;

[0047] 2) According to the alternating load test specification in the GB / T 19055 standard, carry out a 50-100h cycle test on the vehicle, and each cycle runs for 30 minutes. The specific operation is as follows: image 3 Shown (solid line means full throttle):

[0048] a. Fully open the throttle, from the speed of maximum net torque (n M ) rises evenly to the speed of maximum net power (n P ), which lasted 1.5min; at n P Run stably for 3.5 minutes; then drop to n evenly M , which lasted 1.5min; at n M Stable operation for 3.5min. Repeat the above alternating workin...

Abstract

The invention relates to a method for detecting engine oil adaptability, comprising the following steps: connecting an oil-gas separation device between a vehicle oil-gas separation system and an intake manifold; performing an alternating load operation, in which the oil-gas The separation device collects engine oil discharged to the intake manifold by the vehicle's oil-air separation system; and determines whether the engine oil is suitable for the vehicle based on the collected amount of oil. The method for detecting engine oil adaptability of the present invention can accurately evaluate whether the engine oil is suitable for the applied vehicle.

Description

technical field [0001] The invention relates to a simulation test method and device for lubricating oil, in particular to a method and device for detecting engine oil adaptability. Background technique [0002] As a standard for comprehensively evaluating the quality of lubricating oil, countries all over the world tend to be consistent, and a quality standard system consisting of four parts of lubricating oil physical and chemical indicators, simulation test, bench test and driving test has been established. [0003] The physical and chemical indicators to measure the basic performance of lubricating oil include: kinematic viscosity, low temperature dynamic viscosity, viscosity index, flash point, pour point, high temperature and high shear viscosity, evaporation loss, sediment, moisture, foam, residual carbon, sulfate ash, element content, etc. These physical and chemical indicators are only the most basic indicators to measure lubricating oil. [0004] The simulation te...
