How to test various of diesel engine injectors

DIESEL FUEL INJECTION TESTING & REPAIR

The equipment we use to test your diesel fuel injectors and pumps helps us make an informed decision about the best repair solution for your diesel engine. Our goal is to extend the life of your diesel engine and avoid costly downtime for your business.

Common Rail Injector Testing and Repair

Common Rail injectors are becoming increasingly popular as they improve fuel economy and minimize emissions. They are more advanced, but complex compared to other types of diesel fuel injectors, and require a different testing process.

Our equipment provides us the most efficient and precise way to examine modern-high-pressure fuel components.

The equipment we use are:

• BOSCH EPS 205
• BOSCH EPS 815
• DiMeD Express

Our tests help us identify which injectors need repair or replacement so that you don’t have to spend more money replacing everything.

Tests we run:

• High pressure nozzle and control valve leak test
• Idle quantity (LL) OR Idle load (LL)
• Emissions quantity (EM) OR Minimum load (EM)
• Full-load quantity (VL) OR Full-load and back leak (VL)
• Pilot injection quantity (VE) OR Starting test (VE)
• Black smoke
• Not starting
• Injector start behavior (without return flow counter-pressure)
• ISA tuning (Idle Speed Adjustment)
• Electric ‘buzz’ test
• Actuator resistance
• Nozzle

Mechanical Injector Testing and Repair

Although older technology, one of the most common types is still mechanical diesel fuel injector. We test and overhaul a variety of mechanical injectors, including conventional mechanical injectors and 2-spring mechanical injectors.

We test the Mechanical injectors for:

• Spray pattern
• Nozzle chatter
• Opening pressure
• Leaks

Our repaired mechanical injectors are provided with complete installation of washers and seals.
