Example Embodiment
[0015] Such as figure 1 As shown, the simulation device includes a main body 1, a valve guide 2, an exhaust valve 3, an intake valve 4 and so on. The device is made of synthetic resin, which simulates the structure of a cylinder head. The left and right parts of the body 1 are provided with intake ports 1a, exhaust ports 1b, and intake and exhaust valve guide installation inclined holes, and a combustion chamber is provided at the bottom. The valve guide 2 is pressed into the installation oblique holes of the intake and exhaust valve guides on both sides of the body 1 with interference. The exhaust valve 3 and the intake valve 4 are installed in the valve guide 2, which can be slanted along the inside of the valve guide 2. The movement in the direction of the hole simulates the movement state of the valve in the intake and exhaust. The intake port 1a, exhaust port 1b, and combustion chamber 1h are the shapes that need to be inspected. They are made according to the design data ...
