In this case, you can use a professional testing instrument, so that it is completely fine, and the general electronic protractor can achieve such an effect.

First you have to have a cylinder, then make a door, make a little connector, install it, try it, find that the stroke is not enough, throw it away and find a big one, until you find a suitable stroke.
As for how? Have you ever used 3D software? All major manufacturers have 3D model libraries. In addition, the simplest way to open the door is a linear sliding door. This is an early calculation of the trip, the required force, and you can do it.
Complex points can be simulated with slider linkage mechanism on a flat grass layer. Based on your question, I feel that you are not very good at explaining mathematical methods such as geometry, so it is important to improve your knowledge.

It is used to detect the opening angle of the valve, which requires the use of special professional tools, which may only be available to a professional or are familiar with how to operate.
-
Hello, if you open the angle, you can directly use the protractor to measure it to know what the approximate opening angle is. But there are also machines that come with their own measuring system.
-
You can use gladiators to take measurements, or buy some more advanced measuring instruments, such as German products.
-
What is used to detect the opening angle of the valve, it must be to use some special instruments to carry out some detection of special methods.
-
This angle is actually very good, and then you can just open it up and adjust it.
-
There are many angles of opening, and it depends on whether the valve you are detecting is normal.
-
In general, you can do it directly from the background, and you can do it in the inspection.
-
Under normal circumstances, it is necessary to test according to his specific use situation, and this is how it can achieve a good one, which is relatively good.
-
Buying a car is used to basically open up his angle and be able to bring better things to everyone.
-
It's okay, if you think it's okay, it's not okay.
-
What is the small brigade in front? I'll send him to the little van, and that's where the cycle we have to do begins.
-
This is used to detect the opening angle of the valve, and I feel that the range of this angle is quite wide.
-
Detect the opening angle of the valve well, as long as you set it yourself.
-
To detect the opening angle of the valve, you can use some gauges, and there are some angle gauges, you can take a look.
This way you can measure the angle.
-
There are many that can be used to detect the opening angle of the valve.
-
What is used to detect the opening angle of the valve is intimacy discharge.
-
It is used to detect the opening angle of the valve, which can be operated according to the actual situation.
-
Used to detect the opening angle of the valve, you can withdraw money in various forms.

1.pitting of the valve seat;
2.insufficient thickness of valve margin;
3.valve stem bending;
4.valve stem pitting or severe wear;
5.Worn valve lock keyway;
6.Worn valve stem ends.
If any of the above conditions exist, the valves are replaced.
How to check the quality of valves and valve seats.
01 Measurement of valves.
Proper valve repair is critical to engine performance. Therefore, all measurement procedure details must be adhered to in order to identify parts that exceed specifications.
If the measurement procedure indicates that the valve or valve seat must be trimmed, the measurement procedure should be carried out after trimming.
02 Measurement of valve seat width.
Measure the valve seat width in the cylinder head with an appropriate ruler.
How to check the quality of valves and valve seats.
Measure the valve seat width on the valve cone 1 with an appropriate ruler.
How to check the quality of valves and valve seats.
Maintenance tip: The contact surface of the valve seat should be at least mm away from the valve outer diameter (margin). If the valve seat contact surface is too close to the valve margin, the valve seat must be trimmed so that the valve seat contact surface is removed from the margin.
03 Valve seat roundness.
of measurements. Attach the tapered guide rod to the catheter and place the dial gauge.
Attached to the guide rod, the valve seat roundness is measured with a dial indicator. When the guide rod is attached to the catheter, the guide rod should be slightly snapped.
Special note: The correct size guide rod must be used. Never use an adjustable diameter guide rod. Adjustable guide rods can damage the valve guides.
If the roundness of the valve seat exceeds the specification, the valve and valve seat must be grinded.
If a new valve is used, the roundness of the valve seat must be within .
04 Measurement of valve margin.
Measure the valve allowance with an appropriate scale (below).
How to check the quality of valves and valve seats.
If the valve margin exceeds the specification, the valve is replaced.
05 Valve to air trap lack of valve seat concentricity.
of measurements. Special Attention:
Check the valve-to-valve seat concentricity to determine whether the valve and valve seat are properly sealed. Valve cone and valve seat must be measured to ensure proper valve sealing.
Gently apply the blue staining shed manuscript 2 to the valve cone (below).
How to check the quality of valves and valve seats.
Install the valve into the cylinder head.
Turn the valve with enough pressure against the valve seat to grind off the dye.
Remove the valve from the cylinder head.
Check the valve cone.
If the valve cone and stem are concentric, the correct seal will be provided and the imprint around the entire cone 1 should be continuous.
If the valve cone and valve stem are not concentricity, the dye grinding off the imprint on the valve cone will be discontinuous. Valves should be surface trimmed or replaced.

After valve maintenance, it is generally necessary to check the tightness of the valve and the seat ring, generally after the valve and the seat ring are matched, the kerosene is dripped around the valve and the seat ring pit, and placed for a period of time, and the kerosene does not leak to indicate that the seal is good.
1. The engine form determines the grade Generally, according to the different displacements, the engine is divided into three cylinders, four cylinders, six cylinders, eight cylinders, and turbocharging, while L4 (in-line four-cylinder engine) and V6 (V-type six-cylinder engine) and turbocharged models are more common.
2. The engine material is related to the quality Compared with the previous cast iron engine, the advantages of the aluminum engine are really obvious. We all know that the density of aluminum is small, and the engine made of aluminum is naturally light, and the weight of the car equipped with the aluminum engine becomes lighter, which greatly ensures the power efficiency; The aluminum used is very resistant to high temperature and corrosion, and the effect of ventilation and heat dissipation is also better; The physical properties of aluminum itself give good ductility and are more malleable than cast iron, so they are more precise and delicate in the process.
3. The heat dissipation system has a lot of knowledge about the engine, just like the CPU of the computer, while running at high speed for a long time, the requirements for the heat dissipation system are very high, and only by "keeping calm" can we always maintain the stable peak state of engine operation.
4. The design of the air intake pipe is also an important factor affecting fuel consumption Few car owners know that the design of the air intake system is related to fuel consumption. Theoretically, the longer the intake duct, the better, because more filtered air is stored in this way, which is good for the engine to suction. If the length of the intake pipe is designed correctly so that the compression wave will reach the intake valve at the right time, then the volumetric efficiency of the engine can be increased by the fluctuating intake cylinder, and vice versa.

Inspect whether the valve stem is worn and bent to work, whether the cone surface is worn or burned with carbon deposits, check whether the valve stem is broken, whether it is damaged, the valve should be replaced with a new valve, and the valve pin should be disassembled and assembled, so that the hail can not be pressed with the valve money, otherwise the oil seal of the valve will be damaged.
