Multi-Stage Injection Analyzer
FJ-8000 series
Common rail method already is commonly known as an injection system of diesel engine now. That system enables multi-stage fuel injection by offering high injection pressure in various driving situation. Adopting the common rail system helps improving fuel consumption, reducing noise and vibration, because the system can make the fuel approximate complete combustion which suppresses PM and NOx generation. FJ-8000 series is the multi-stage injection analyzer that supports more accurate injection by measuring injection quantity, injection rate, injection timing, and injection period by multi-stage injection of common rail system in the environment that is near to an actual vehicle environment.
