Core Power & Performance Indicators (By Application)
| Application Scenario (Code) | Rated Power Range | Rated Speed (RPM) | Core Performance & Characteristics |
|---|---|---|---|
| Construction Machinery (C) | 220 hp - 450 hp (164 kW - 336 kW) |
1800 - 2200 RPM | * Focuses on low-speed, massive torque and high torque backup (torque rise up to 30%). * Max torque reaches 1350 - 1800 N·m (at 1300-1500 RPM). |
| Generator Drive (G) | 240 kW - 400 kW (Max Standby up to 410kW) |
1500 RPM (50Hz) 1800 RPM (60Hz) |
* Emphasizes constant speed control. * Paired with an EFC electronic actuator, transient governing response rate is typically ≤ 1%. |
| Marine Power (M) | 240 hp - 400 hp (179 kW - 298 kW) |
1800 - 2100 RPM | * Prioritizes service life under continuous full-load and full-power output. * Usually equipped with sea-water / fresh-water heat exchanger cycles. |
Maintenance Adjustments & Installation Interface Parameters
| Parameter | Technical Standards & Specifications | Remarks / Details |
|---|---|---|
| Intake Valve Clearance (Cold) | 0.28 mm (0.011 inch) | Stamped on the rocker housing data plate; must be precise after overhauls |
| Extractor Valve Clearance (Cold) | 0.58 mm (0.023 inch) | Exhaust valves have a wider gap due to larger thermal expansion |
| Injector Lift / Travel | Subject to PT pump calibration card (e.g., 5.33mm or O.B.C. method) | Core mechanical adjustment item affecting fuel atomization and exhaust smoke |
| Flywheel Housing Interface | Generally SAE 1# or SAE 0# | Determines how the assembly couples with FAST gearboxes, torque converters, or single-bearing alternators |
| Flywheel Ring Gear Teeth | 103 Teeth or 113 Teeth (Depends on matching starter motor) | A crucial parameter to verify when replacing or servicing the starter motor |
| Electrical System Voltage | 24V DC (Two-wire insulated or single-wire grounded) | Includes a 24V starter motor and a 24V charging alternator |
