A diesel engine’s performance and emissions depend heavily on diesel fuel injection system components. Most importantly, fuel injectors/nozzles play a key role in the pumping process. A diesel engine’s injectors and nozzles must perform, emit, be reliable, and last for a long time. We manufacture the injector nozzle holes to strict specifications using the latest EDM technology, and they are thoroughly tested with laser optic electronic devices to make sure they fit inside the precise dimensions. Injectors and nozzles are designed to perform exactly as they should for long service life.
