The John Deere 6068H is a 6-cylinder, 6.8-liter industrial diesel engine widely used in excavators, loaders, tractors and generator sets. It adopts HPCR High-Pressure Common Rail Fuel System, with max rail pressure up to 1600 bar. Controlled by ECU, it supports multiple injections (pilot, main & post injection) for optimized combustion, lower fuel consumption and emissions, and stable power under heavy loads.

Main Components

  1. Common Rail Injector

    The core actuator of fuel system. The ECU precisely controls injection timing and fuel quantity. Excellent atomization reduces black smoke and engine noise. Supplied with hold-down clamps, bolts, copper gaskets and O-rings. Can be overhauled or replaced individually when leaking or poor atomization occurs.

  2. High Pressure Fuel Pump

    Generates high pressure fuel and delivers to common rail. Built-in pressure sensor sends real-time pressure feedback to ECU to adjust rail pressure dynamically. 6068H uses Denso HP3 style high-pressure pump.

  3. Common Rail / Fuel Rail

    Accumulates and stabilizes high-pressure fuel, evenly distributing fuel to each cylinder. It absorbs pressure fluctuation to ensure consistent injection pressure for every cylinder. The rail pressure sensor feeds pressure data to ECU.

  4. High Pressure Fuel Lines

    Heavy-duty high-pressure steel pipes connecting common rail and injectors, anti-leakage for reliable fuel delivery.

  5. Sensors & Seal Repair Kit

    Including rail pressure sensor, fuel temperature sensor, O-rings, copper washers and valve components. Oil leakage and pressure loss are mostly caused by aging seals. Repair kits cut service cost instead of replacing whole assemblies.

Key Advantages

✅ Max injection pressure: 1600 bar, multi-injection strategy for better power and fuel economy

✅ Full ECU electronic control, adjusts injection according to engine load & speed

✅ Dual-stage fuel filtration (10μm primary + 2μm secondary), protects precision components

✅ Applications: Excavators, wheel loaders, tractors, diesel generators, forestry machines
