J5700-1113240A
Yutong Bus Parts
| Attribute | Specification |
|---|---|
| Part Number (P/N) | J5700-1113240A, J5700-1113240A-P64 (improved version) |
| Product Name | High-Pressure Natural Gas Regulator / Two-Stage Pressure Reducer |
| Brand Compatibility | Yuchai (YUCHAI) CNG/LNG Engines |
| Fuel Type | Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) |
| Application Type | Single-Fuel or Dual-Fuel Natural Gas Engines |
| Housing Material | Die-Cast Aluminum Alloy (high strength, lightweight, corrosion resistant) |
| Internal Components | Stainless Steel Valve Seat, Special Anti-Erosion Synthetic Rubber Diaphragm |
| Weight (Net) | ~1.65 kg |
| Dimensions (L×W×H) | Approx. 165 mm × 140 mm × 130 mm |
| Mounting Style | Bracket-mounted with rubber isolators; compatible with standard engine layout |
| Parameter | Detail |
|---|---|
| Inlet Pressure (Max) | 20 MPa – 25 MPa (suitable for CNG cylinder banks) |
| Outlet Pressure (Rated) | 0.7 MPa – 0.9 MPa (adjustable within range; typically set at 0.8 MPa) |
| Regulation Stages | Two-Stage Reduction System: – Stage 1: High-to-medium pressure drop – Stage 2: Fine-tuned stabilization for ECU-controlled injectors |
| Temperature Range | -40°C to +120°C (operational under extreme climates) |
| Heating System | Integrated coolant passage for forced circulation of engine cooling water; prevents freezing due to Joule-Thomson effect during gas expansion |
| Flow Capacity | Supports up to 300 Nm³/h (depending on engine load and RPM) |
| Response Time | <0.1 seconds to stabilize pressure after transient demand changes |
| Sealing Performance | Leak-tight design per ISO 15848; no visible leakage under normal operating pressure |
| Connection Fittings | - Inlet: M12×1.5 thread or ferrule-type compression fitting – Outlet: Large-bore low-pressure hose connection (typically Ø12–16 mm) |
