5. Technical Information Compensation of injected-fuel-quantity New functions are added to common-rail systems to enhance the high precision of the fuel-injection system further, and ensure them for the service life of the vehicle. With injector delivery compensation (IMA), a mass of measuring data is detected for each injector during the injector manufacturing process. - Page 18 6-1 PIEZO Injector Test ※ Piezo Injector is not an previous Solenoid Type. Piezo injector making satisfy 1) Set-up Method method of the high exhaust, power and precision. ※ Previous Solenoid Valve needs an oil pressure coupler to help limited movement of Piezo injector and there is a system to maintain the oil pressure coupler for the safety maintain of it.
