Sensei STB-366 Multifunctional Test Bench

Overview

Sensei STB-366 Common Rail Test Bench is a professional testing system designed for comprehensive functional testing of high-pressure common rail systems. It enables accurate and efficient diagnosis of injectors and pumps across a wide range of diesel fuel systems.

Common Rail Injectors & Common Rail Pumps

Performs high-pressure cleaning to remove impurities inside injectors
Conducts atomization tests to determine injector blockage through spray pattern analysis
Checks sealing performance to detect oil leakage from the nozzle, nozzle cap nut, and solenoid valve
Measures injection and return volumes under multiple operating conditions (VL, TL, LL, VE)
Fully automatic testing, supporting single-injector testing per cycle
Compatible with common rail pumps including BOSCH CP1 / CP2 / CP3, DENSO HP2 / HP3 / HP0, DELPHI, SIEMENS

EUI, EUP, HEUI & CR Pumps

Automatically tests injection volume, return volume, pump chamber pressure, feeding pressure, and sealing performance for BOSCH, SIEMENS, DENSO, and DELPHI common rail pumps
Supports automatic testing for BOSCH, CUMMINS, DELPHI, DENSO, Mercedes-Benz, Volvo, EUI/EUP systems, and dual-valve E3 systems
Enables specialized testing for DENSO HP0 pumps, including double and single electromagnetic sensor configurations
Supports testing of HEUI C7, C9, and 3126 injectors
Fully supports EUI and EUP injector testing

Sensei STB-118 Common Rail Test Bench

Sensei STB-118 independently researched professional device designed to evaluate the performance of high-pressure common rail injectors. It is operated via an industrial computer running a Windows operating system. Fuel quantity is detected by sensors and displayed on the computer screen through an electronic fuel delivery system. All test data can be searched and stored.

The system uses original BOSCH (DENSO) common rail pumps to generate rail pressure up to 0–2600 bar (DENSO). Rail pressure is automatically adjustable and includes overload protection. The test bench is compatible with common rail injectors from BOSCH, SIEMENS, DELPHI, and DENSO, offering advanced technology, stable operation, accurate measurement, and user-friendly performance.

CHARACTERISTICS

Real-time control via industrial computer with Windows operating system.
Fuel quantity measured by sensors and displayed on a 10.4-inch touch LCD screen.
Database support for over 8,000 injector models, searchable and usable.
Equipped with BOSCH (DENSO) common rail pump, providing 0–2600 bar pressure for DENSO rail systems.
Real-time rail pressure monitoring capability.
Integrated rail pressure overload protection for DENSO systems.
Adjustable injector pulse and frequency parameters.
Configurable injection timing.
Short-circuit protection function.
High measurement accuracy, simple operation, and low noise level.

FUNCTIONS

Supports injector testing for BOSCH, SIEMENS, DELPHI, and DENSO brands.
Enables testing of a single injector per cycle.
Performs pre-injection testing for common rail injectors.
