Abstract
The invention provides a test method for oil consumption of a direct injection engine. The general thought of the test method is to utilize an oven to obtain percentage result of oil dilution and calculate an actual value of oil consumption according to the result. The test method adopts the oven for baking measurement to remove influence of oil dilution on the result of the oil consumption, so as to meet the requirement of obtaining test result quickly and detect the oil consumption accurately and timely, and the test method has the advantages of short test time, simple equipment structure, high practicability and the like.
Description
Technical field
The invention belongs to technical field of engines, be specifically related to a kind of measuring technology of oil consumption.
Background technology
Current direct fuel-injection engine inevitably exists due to oil dilution, the traditional detection means of oil consumption test owing to lacking oil dilution, and when computing machine oilconsumption not by gasoline removing wherein, the result obtained is often much less than normal.Traditional technology is all a measuring machine oil consumption, and means are different but all the impact of gasoline cannot be eliminated.If the amount of gasoline in the result obtained will be removed, then need to adopt the complicated methods such as stratographic analysis could determine the content of gasoline, whole process is time-consuming oversize, can not obtain result fast, affects test progress time-consuming.
Summary of the invention
The invention provides a kind of method of testing of direct fuel-injection engine oil consumption, adopt oven cooking cycle to measure and remove oil dilution to the impact of oil consumption result, make it can meet the requirement obtaining test findings fast, the accuracy of test findings can be met again.
The general thought of method of testing of the direct fuel-injection engine oil consumption that the present invention proposes be utilize baking box obtain oil dilution percentage result and according to its object computer oilconsumption actual value.Its concrete steps comprise:
S1: first add machine oil W within the engine
start, run engine, carry out consumption of lubricating oil test in h hour, then release the potpourri W in oil sump
terminate;
S2: sample in releasing potpourri 5min, this sample quality controls at 10 ~ 15g, and the quality of weighed samples is W
before baking, sample is put into baking box, and oven temperature control is 120 DEG C or is the maximum temperature that corresponding model machine oil allows, and baking time is 2 hours, and sampling quality after baking terminates is W
after baking;
S3: according to the change of sample quality before and after baking, namely obtain sample is that engine oil consumption releases potpourri W
terminatein machine oil percentage composition=W
after baking/ W
before baking, obtain oil consumption=W
start-W
terminate* W
after baking/ W
before baking, oil consumption per hour=(W
start-W
terminate* W
after baking/ W
before baking)/h.
The inventive method can eliminate the impact of gasoline in direct fuel-injection engine consumption of lubricating oil test process, oil consumption can be detected accurately and timely, have that test period is short, device structure is simple and the advantage such as practical, the method for testing of the accurate direct fuel-injection engine oil consumption of result can be set up on this basis.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Embodiment
In order to make the personnel of technical field better understand the present invention program, below in conjunction with accompanying drawing 1, the present invention is described in further detail.
As shown in Figure 1, the present embodiment comprises:
S1: first add machine oil W within the engine
start, run engine, carry out oil consumption test in h hour (h hour is random time length, can calculate oil consumption per hour according to h), then release potpourri W
terminate;(because the machine oil of releasing contains gasoline, being therefore called potpourri);
S2: the potpourri W released with open mouth glass beaker in releasing potpourri 5min
terminatemiddle sampling, the quality of weighed samples is W
before baking(this sampling quality is preferably less than 10g), the open mouth glass beaker containing sample is put into baking box, oven temperature control is the maximum temperature (when being less than 120 DEG C) of 120 DEG C or the permission of corresponding model machine oil, and baking time is 2 hours.The sample quality of weighing in open mouth glass beaker after baking terminates is W
after baking.
S3: according to the change of sample quality before and after baking, namely obtain sample is that engine oil consumption releases potpourri W
terminatein machine oil percentage composition=W
after baking/ W
before baking.Machine oil percentage composition is multiplied by the total amount W that oil consumption has tested rear machine oil
terminate, can obtain the machine oil content in its potpourri, the difference that engine oil consumption has tested the total amount of front and back machine oil is oil consumption, i.e. oil consumption=W
start-W
terminate* W
after baking/ W
before baking, oil consumption per hour=(W
start-W
terminate* W
after baking/ W
before baking)/h.
In this method, owing to being difficult to volatilization in the temperature environment of machine oil below 120 DEG C, therefore gasoline contained in sample, moisture can being evaporated away completely and do not affect the change of machine oil content.
In this method, can only by the way of oven cooking cycle, if exposed heating, the gasoline evaporated etc. easily produce blast or initiation fire.
In this method, with open mouth glass beaker sampling requirement in 5min, the gasoline in such guarantee sample and the evaporation of moisture can not affect the accuracy in computation of result.
In this method, due to the abundant stirring of machine oil potpourri in consumption of lubricating oil testing experiment, the machine oil percentage composition that fired sample obtains can be thought and equals to release potpourri W
terminatein machine oil percentage composition.
Last it is noted that for a person skilled in the art, it can be modified to aforesaid technical scheme, or carries out equivalent replacement to wherein Partial Feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
