Product Introduction
In modern high-performance engines from Caterpillar Inc., the injector is not just a component-it is a calibrated actuator within a closed-loop combustion control system. Unlike conventional mechanical injection, the 342-5487 common rail diesel injector operates as a digitally governed unit, synchronizing with ECU strategies to achieve optimized combustion phasing.
This injector is engineered for diesel-powered compression ignition systems, where fuel atomization and injection timing directly influence torque density, emissions compliance, and thermal efficiency.
Application Scope & Engine Compatibility
The 342-5487 injector is widely utilized in heavy-duty off-highway and industrial diesel engines, particularly in:
Construction machinery (excavators, loaders)
Mining equipment
Power generation diesel sets
Marine auxiliary engines
On-highway vocational trucks
Its design aligns with high-load duty cycles, making it suitable for engines operating under continuous high-pressure combustion conditions.
Key Technical Data
| Parameter | Specification |
|---|---|
| Injection System | Common Rail Direct Injection (CRDI) |
| Max Rail Pressure | Up to 1800–2500 bar |
| Control Type | Solenoid-controlled |
| Spray Pattern | Multi-hole precision nozzle |
| Response Time | <1 ms (typical) |
| Fuel Type | Diesel (compression ignition medium, not gasoline) |
These parameters ensure stable atomization even under transient load conditions, improving combustion uniformity.
