XICHAI / FAWDE Aowei 6DL2 Series Heavy-Duty Inline-Six Diesel Engine CA6DL2-37E3F
Mechanical Structure & Basic Specifications
| Core Item | Technical Indicator & Parameter | Key Feature & Design Highlight |
|---|---|---|
| Engine Type | Inline, 6-Cylinder, 4-Stroke | Compact structure, universal golden layout for heavy-duty trucks and dump trucks. |
| Valvetrain Structure | 4 valves per cylinder (2 intake, 2 exhaust), Overhead Camshaft (OHC) | High gas exchange efficiency, smoother intake and exhaust under heavy workloads. |
| Aspiration Mode | Turbocharged & Intercooled | Increases intake air density, significantly boosting power output in high-altitude conditions. |
| Displacement | 8.57 Liters (Commonly referred to as 8.6L) | Golden displacement of the Aowei DL2 platform, balancing dead weight and high torque. |
| Bore × Stroke | 112 mm × 145 mm | Long-stroke design, delivering explosive low-speed torque for heavy-duty hill climbing. |
| Compression Ratio | 17.5 : 1 | High compression ratio, ensuring optimal fuel-air mixing and combustion under high pressure. |
| Firing Order | 1-5-3-6-2-4 | Standard 6-cylinder firing order, excellent engine balance, low noise, and low vibration. |
| Flywheel / Housing Spec | Standard SAE 1# or SAE 2# | Highly compatible, perfectly matches FAST and FAW proprietary transmissions. |
Dynamic Performance & Economic Indicators
| Core Item | Official Standard Data | Operational Workload Interpretation |
|---|---|---|
| Rated Power (kW) | 279 kW | Belongs to the highly efficient mid-to-heavy truck power band for tippers and tractors. |
| Metric Horsepower | 375 HP (Some certificates show 370 HP due to local regulation variations) | Offers an extreme advantage for 30–40 ton loaded vehicles during startup and hill climbing. |
| Rated Speed | 2100 rpm | The standard maximum speed engine limit when outputting maximum power. |
| Maximum Torque | 1450 N·m to 1650 N·m | Prevents stalling when starting under heavy loads or navigating steep inclines. |
| Max Torque RPM Range | 1200 rpm - 1500 rpm | Golden Economic Speed Range, offering the best fuel efficiency when driving within this RPM band. |
| Idle Speed | 600 ± 50 rpm | Standard idle speed under zero-load conditions. |
| Minimum Fuel Consumption | ≤ 178 g/kW·h | Outstanding fuel economy, superior to most traditional diesel engines of the same displacement. |
| Max Gradeability Support | Over 40% (Depending on vehicle rear axle gear ratio) | Highly suitable for harsh engineering conditions such as mines and construction sites. |
Lubrication, Cooling & Emission Control
| Core Item | Technical Indicator & Parameter | Key Components & Technical Requirements |
|---|---|---|
| Emission Standard | Euro III (China Phase III / 国Ⅲ) | Highly popular in overseas export markets (e.g., Africa, Central Asia, Southeast Asia). |
| Aftertreatment Tech | Electronic High-Pressure Common Rail (No AdBlue/Urea required) | Euro III models do not need EGR or SCR Urea systems, resulting in low maintenance costs. |
| Engine Oil Capacity | Approx. 24 - 28 Liters (Initial fill / After overhaul) | Utilizes a large-capacity oil pan to ensure steady lubrication under high-intensity operations. |
| Standard Oil Pressure | Idle: ≥ 100 kPa / Rated Speed: 300 - 500 kPa | Must be paired with a high-flow oil pump (such as a heavy-duty gear pump). |
| Cooling System Capacity | Approx. 40 Liters (Including radiator & cabin heating loop) | Forced water cooling circuit, preventing engine overheating during extreme summer heat. |
| Thermostat Temperature | Initial Open: 76℃, Fully Open: 86℃ | Precisely regulates warming speed to prevent low-temperature wear or high-temperature cylinder scuffing. |
Electrical & Fuel Control Systems
| Core Item | Technical Specification / Model | Purchasing & Maintenance Notes |
|---|---|---|
| Fuel System Type | Electronic High-Pressure Common Rail System | Mostly paired with premium BOSCH common rail systems featuring ultra-high injection pressure. |
| System Voltage | 24 V (Direct Current - DC) | Standard heavy-duty truck dual-battery series 24V power supply system. |
| Starter Motor Power | 24V / 5.5 kW or 7.5 kW | Ensures easy ignition of the large 8.6L engine in cold climates or winter seasons. |
| Alternator Specification | 28V / 70A or 80A | Provides ample electrical power for vehicle lighting, air conditioning, and electronics. |
| ECU (Engine Control Unit) | BOSCH EDC16 / EDC17 series or FAW proprietary board | The "electronic brain" of the engine. Must be strictly protected against water or short circuits. |
