LEAK TESTING OF THE THE VALVE SEATS ON ENGINE HEADS
CHECK MADE BY AN AIR-TO-ELECTRONIC GAUGE
The manual plug is provided with an annular slit jet to check the valve seat combination errors of roundness and seat angle. The E4N column display gives measure of air leakage between the conical reference of the plug and the valve seat. Exceeding upper leakage limit (approximately 400 cm3 / min) indicates shape error.
The leakage plug, is interfaced with the microprocessor E4N AIR column. "Zero leakage" and "Maximum leakage" masters are always supplied with the manual gauge. The proposed solution permits a 100% check of all parts, allowing quality control of the entire production.
This equipment is used along with an E9066N Flat Panel electronic unit.
