Diesel Engineering Services repair and calibrate the following Yanmar pumps and injectors:
| Category | Type | Description |
|---|---|---|
| Fuel Pumps | Mechanical (Camshaft-Driven) Pumps | Traditional injection pumps using mechanical timing and control. |
| Rotary (Distributor) Pumps | Common in small to medium Yanmar engines, offering reliable delivery. | |
| Common Rail Pumps | Used in modern engines for high-pressure fuel delivery with electronic control. | |
| Electronic Fuel Injection Pumps | Incorporate electronic controls for precise fuel management. | |
| Injectors | Mechanical (Nozzle-Style) Injectors | Simple, mechanically operated injectors, typically in older models. |
| Solenoid Injectors | Use solenoid actuators for precise injection control. | |
| Piezoelectric Injectors | Employ piezoelectric elements for extremely accurate and rapid injection. | |
| Common Rail Injectors | Designed for high-pressure common rail systems with electronic control. |
Additional notes:
- Yanmar primarily uses mechanical injection systems in older models and has transitioned to electronic and common rail systems in newer engines.
- Injector types vary depending on the engine model, application, and whether the system is traditional or modern.
