1.Introduction
CRS-708S test bench is special device to test the performance of high-pressure common rail pump and injector, it can test common rail pump, injector of BOSCH, SIEMENS, DELPHI and DENSO and piezo injector. It simulates the injection principle of common rail motor completely and the main drive adopts the most advanced speed change by frequency change. High output torque, ultra low noise. It tests the common rail injector and pump by flow sensor with more precise and stable measurement. It can add EUI/EUP test system and CAT C7 C9 , test CAT 320D common rail pump. Pump speed, injection pulse width, oil measurement and rail pressure are all controlled by industrial computer by real time. The data is also obtained by computer. 19〃 LCD screen display makes the data more clear, more than 2900 kinds of data can be searched and used. Advanced technology, steady performance, precise measurement and convenient operation.
CRS-708S can fulfill the remote assistance by internet and make the maintenance easy to operate.
