Fuel measurement System

Multi-stage injection measurement system


Common rail fuel injection system in diesel engines is a fuel injection system which improves output performance and fuel consumption by purifying exhaust gas (soot, NOX) and reducing noise and vibration.
The fuel is completely burned by being sprayed in the form of mist which burns easily at high pressure, and furthermore the combustion timing is optimized with electronic control.
In this common rail injection system, injection timing by an electric controlling has great effect on the performance of an engine. So measurement of injection amount, injection rate, and injection timing are very important. FJ-8000 series Multi-Stage Injection Analyzer is able to measure those parameters for every 1 cycle by simulating in the environment which is near to an actual vehicle running.
