Abstract

PROBLEM TO BE SOLVED: To improve environmental problems by accurately and quickly detecting a vehicle to be inspected in an initial failure state. SOLUTION: A blow-by gas inspection machine 3 takes in a blow-by gas that is directly blown into an engine oil injection opening 103 from the inside of an engine 102, instead of an exhaust gas, that is discharged from the exhaust pipe of a vehicle 101 to be inspected via a catalyst, thus inspecting the degree of deterioration in an engine oil and the degree of abrasion in the engine 102. As a result, a far more accurate inspection than the measurement of the concentration of an unburned constituent can be made in an exhaust gas.

Good. The pass / fail determination means 73 of the management device 52
During or after the inspection of both 101, from the control device 51
Based on each inspection data sent, each inspection result
Determine pass / fail. Specifically, the blow-by gas inspection machine 4
The concentration of unburned components of blow-by gas measured in
Low engine oil depending on the level of
Judgment of the degree of conversion and engine wear. In this case, blow
The higher the concentration of unburned components of the bigas, the more
Of the engine oil has deteriorated,
It can be determined that the engine is getting worn. The pass / fail determination means 73 is provided to the exhaust gas inspection device 5.
Measured during idling and load
The concentration of each component of the gaseous gas is analyzed, and the pass / fail is determined.

The fuel consumption and the breakdown of engine 102 parts.
Can be determined. The pass / fail determination means 73 is a lateral force test
Of each tire 111A-111D measured by the machine 6
From the force measurement result, the pass / fail is determined. This place
The greater the lateral force, the worse the fuel economy
There is a possibility that abnormal wear of the tires 111A to 111D and running instability may occur.
Yes, especially with waste from tires 111A-111D
There is also concern that the frontier will decline. The pass / fail determination means 73 is provided by the drive balance checker 7
Calculate the speed of each drive wheel measured by and the difference,
The pass / fail of the inspection is determined. In this case, the power of the engine 102
Ideally, it should be transmitted to each drive wheel evenly and without resistance.
The balance of the transmission force is lost due to the failure of the differential device 113
And the speed difference between the driving wheels increases, and the engine 102
When the resistance to each drive wheel increases, the
The speed decreases. And in this case, fuel economy gets worse
Tires, abnormally worn tires, and unstable running
This will lead to malfunctions. The pass / fail determination means 73 includes a shock absorber detection
Resonance circumference of each tire 111A to 111D measured by the probe 8
The pass / fail of the inspection is determined based on the wave number and the grounding ability. this
In this case, the value of the grounding ability decreases or
Increases, the ability to follow the road from tires 111A to 111D
Decreased, fuel economy worsened, and the ride became worse
This causes a problem that the traveling becomes unstable. This is the inspected car
Due to deterioration of both 101 shock absorber and spring
However, such deterioration can lead to misalignment and
War loss occurs and the environmental impact is increased. And
Therefore, by conducting a shock absorber test,
The boundary can be improved. The pass / fail determination means 73 is a vacuum waveform inspection machine.

Pass / fail of the inspection for the overall combustion state of the engine.
Vacuum waveforms generally indicate the movement of pistons in engine 102.
Pulsating with sparks, for example, the spark plug is dirty
The pulsation becomes irregular as it becomes constant. By the way, conventionally, oscilloscope
Low resolution of scope 42, linearizing vacuum waveform
Can be observed only, the negative pressure of the engine 102 is a constant gauge value
Judgment at was done. Therefore, the vacuum waveform
, A highly accurate inspection could not be performed.
In this regard, in this embodiment, the details of the vacuum waveform can be observed.
The oscilloscope 42 is used to
Find the initial fault condition in the lag and take necessary action
Can be performed. The pass / fail determination means 73 includes an automatic

Status), danger (conditions requiring immediate replacement or adjustment of parts)
The evaluation is performed in three stages of (state), for example, two stages
Alternatively, four or more levels of evaluation may be used. Thus, three stages
With the above evaluations, although there is no hindrance to driving,
It is possible to know that this is a periodic malfunction state. Ma
Also, the result of the pass / fail judgment and evaluation by the pass / fail judgment means 73
Is performed when there is a print command described later.
The inspection data is sent from the controller 51.
