Common Rail Injector Nozzle | High-performance diesel engines | Material: Stainless Steel (ASTM A240) ▲▲ Pressure Rating: 2500 bar (ISO 14385) ▲▲ Spray Angle: 160° (SAE J1839) | ▲▲ High-pressure tolerance (2500 bar vs industry 1800 bar) Precise fuel atomization | Higher cost ($250–$400/unit) Requires specialized maintenance tools |
Unit Injector Nozzle | Medium-duty trucks, agriculture | Material: Carbon Steel (ASTM A36) Pressure Rating: 1800 bar Spray Angle: 140° | Simpler design lowers cost ($120–$200/unit) Rugged durability for harsh environments | Lower pressure capacity limits performance in high-output engines |
Pintle Nozzle Injector | Marine engines, stationary generators | Material: Brass (ASTM B28) Flow Rate: 50–80 LPH (ISO 1217) Temperature Range: -20°C to 150°C | ▲ Wide temperature tolerance Cost-effective ($80–$150/unit) | ▲▲ Lower spray precision (10% variance) Prone to clogging in dirty fuel |
Piezoelectric Injector Nozzle | Luxury vehicles, hybrid systems | Response Time: 0.1 ms (ISO 14385) Pressure Rating: 2000 bar ▲ Energy Efficiency: 92% (IEC 60038) | ▲▲ Ultra-fast response for micro-dosing Low power consumption | Fragile piezoelectric crystals require gentle handling ($300–$500/unit) |
Mechanical Plunger Nozzle | Vintage engines, industrial machinery | Material: Cast Iron (ASTM A48) Pressure Rating: 1200 bar Lifespan: 10,000 hours (ISO 14385) | ▲ Long lifespan No electronic dependency | ▲▲ Lower precision (±5% fuel delivery) Heavy and bulky design |
Hydraulic Nozzle Injector | Mining equipment, heavy-duty machinery | Material: Alloy Steel (ASTM A387) Flow Control: 3-stage valve ▲ Max Load: 500 bar ▲▲ | ▲▲ High load capacity Rugged for extreme vibrations | ▲▲ Limited spray pattern flexibility Higher maintenance frequency |
