the design of the engine must ensure that the opening of the engine combustion chamber is properly sealed. In order to achieve this goal, the material of the engine block, the bolt, the bolt lubrication, the bolt torque and the bolt sequence, and the gasket design must be carefully selected and determined. The I-Scan film pressure analysis system can measure the dynamic pressure distribution state, adjust the clockwise rotation of the pointer to be equal to the high value of the indication, and provide the designer with accurate and real-time pressure size and distribution data to make good choices and decisions

the following case is the case of using I-Scan system to test ③ in cylinder gasket The fixture itself is a locking mechanism and a fire ring as the pressure distribution during assembly, so as to simulate the state of the cylinder combustion cycle, so as to obtain the pressure and distribution of the cylinder gasket on the engine during the cylinder combustion cycle. First place the I-Scan membrane pressure sensor between the engine surface and the cylinder gasket and lock it with a torque wrench. I-Scan software starts to record the whole test process. During the test process, the test conditions can be changed. Apply a thin layer of MoS2 (molybdenum sulfide 2) grease regularly for different tests; Regularly check the screw value of the jaw and it will be displayed on the computer screen for analysis. In Figure 2, it can be clearly seen that the uneven distribution of pressure and large pressure appear at the place where the valve ring is close to the bolt. Use a torque wrench to turn the fastener for another 45 degrees to strengthen the fastening force, and then record the pressure value as shown in Figure 3. Similarly, use a torque wrench to turn the fastener for another 45 degrees to strengthen the fastening force, and then record the pressure value as shown in Figure 4. So far, the engine has been pressurized three times. Next, depressurize the engine three times to simulate the combustion cycle of the engine. The pressure distribution data is recorded in Figure 5. It can be seen from Figure 5 that the pressure of the cylinder gasket on the engine has slightly decreased, which is caused by the fact that the valve slightly propped up the cylinder gasket when supercharging compared with the same period in 2012. Figure 6 shows the final test results. After the test, Figure 7 shows the pressure comparison diagram before and after the test, which shows that there is nearly 5% pressure reduction

i-scan system can also be dynamically tested to understand the impact of vibration and torque on the cylinder gasket pressure on the engine under the state of motion. I-Scan system is the only tool that can conduct dynamic pressure test on seals at present
