Key Features

1. Powerful Drive System

The ES816 uses a 22 kW motor with variable-frequency speed control. It provides stable operation, high output torque and a small speed drop under load.

The variable-speed system allows technicians to select different testing speeds according to the pump type and testing requirements.

2. Multi-Cylinder Fuel Delivery Measurement

The test bench can measure the fuel delivery quantity of individual cylinders at different speeds.

Up to 12 flow sensors are available for precise measurement and comparison of fuel delivery between cylinders. This helps technicians identify uneven fuel delivery and make accurate pump adjustments.

3. VE Distribution Pump Testing

The ES816 is equipped with a dedicated VE pump flow measurement system and supports testing of VE distribution pumps.

Testing functions include:

• VE pump return oil quantity measurement

• Internal pressure measurement

• Solenoid valve testing

• 12V/24V solenoid valve control

• Supply pump testing

• Pump sealing inspection

• Advance device testing as an optional function

4. Injection Timing and Governor Testing

The ES816 can test the fuel delivery point and delivery interval angle of mechanical injection pumps.

It can also be used to inspect and adjust:

• Mechanical governors

• Boost compensators

• Fuel compensation devices

• Pump delivery characteristics

• Injection timing mechanisms

5. Computerized Measurement and Data Management

The computer control system monitors and displays important testing parameters in real time.

Depending on the configuration, the system can measure and control:

• Pump speed

• Test count

• Fuel temperature

• Air pressure

• Feed angle

• Rack travel

• Fuel delivery quantity

Test results can be displayed on a computer interface, with an optional 17-inch LCD touchscreen available according to customer requirements.

6. Pump Database and Test Reports

The ES816 allows testing data to be managed digitally.

Technicians can:

• Save pump testing data

• Modify testing parameters

• Upload data to the pump database

• Search pump data quickly

• Generate test reports

• Print test results

• Display speed characteristics and rack-travel curves

This makes the ES816 suitable for professional workshops that need repeatable testing procedures and organized customer records.
