Title: Early detecting method for exhaust valve blow-out in internal combustion engine
Inventor: NITTA KEIICHI
IPC: F01L3/24
Filed: 1986-11-12
Abstract: PURPOSE:To improve the reliability in detecting the blow-out phenomenon through an exhaust valve by performing the detection on the basis of the difference between vibration of the valve case of a cylinder and the vibration of a cylinder cover. CONSTITUTION:The vibration of the valve case 2 of a cylinder is detected by a vibrometer 4. The vibration of a cylinder cover 3 is detected by a vibrometer 5. Both the vibration measurements are sent to a CPU 9 to compare therein.
