Basic Mechanical Architecture
| Parameter Dimension | Core Technical Specifications | Industry Analysis & Advantages |
|---|---|---|
| Engine Type | In-line, Water-cooled, 4-stroke, Overhead Valve (OHV) Diesel Engine | A classic 4-cylinder engine platform designed for light to medium-duty engineering vehicles. |
| Number of Cylinders | 4 Cylinders | Monoblock cast iron cylinder block with a high-rigidity structural design. |
| Bore × Stroke | 108 mm × 115 mm | Large bore and long stroke design, optimized for high torque output at low speeds. |
| Total Displacement | 4.214 L (4.2L Class) | Larger displacement compared to peer 3.8L engines, providing plenty of power reserve. |
| Aspiration Type | Turbocharged & Intercooled | Increases intake air density to improve combustion efficiency under heavy loads or high-altitude environments. |
| Piston & Connecting Rod | Alloy monoblock cast piston with full-floating wrist pin | Built to withstand high combustion pressure, significantly extending the overhaul cycle under heavy-duty operations. |
| Engine Net Weight | Approx. 380 kg - 410 kg (Varies slightly with flywheel housing/pulley configurations) | Solid material usage in its class, offering excellent vibration resistance and fatigue life. |
Power & Combustion Performance
| Parameter Dimension | Core Technical Specifications | Industry Analysis & Advantages |
|---|---|---|
| Rated Power | 96 kW (130 hp) | Recognized as the "Golden Power" standard for light/medium-duty tippers and truck-mounted cranes. |
| Rated Speed | 2800 RPM | Higher rated speed, ensuring sufficient vehicle speed during highway transport. |
| Maximum Torque | 380 N·m to 420 N·m | Offers strong explosive power during hill climbing, pulling out of mud, and heavy-duty starts. |
| Max. Torque Speed | 1400 - 1700 RPM | A wide economic speed range that effectively reduces fuel consumption during heavy-duty operations. |
| Emission Standard | Euro 3 (China Stage III) | Typically utilizes a High-Pressure Common Rail system or a Mechanical Pump setup equipped with an electronic EGR. |
| Min. Fuel Consumption | ≤ 198 g/kW·h | Achieved via optimized combustion chamber design from Germany's FEV, ensuring excellent fuel atomization. |
| Compression Ratio | 17.5 : 1 | High compression ratio design ensures reliable cold starts in freezing regions. |
Electrical, Pneumatic & Auxiliary Systems
| Parameter Dimension | Core Technical Specifications | Industry Analysis & Advantages |
|---|---|---|
| System Voltage | 24 V Standard Automotive Control System | Matches the standard 24V electrical layout found in domestic dump trucks and heavy-duty trucks. |
| Starter Motor Power | 24 V / 4.5 kW Reduction Starter | High-power starter motor enables easy starting even in low temperatures during winter. |
| Alternator Capacity | 28 V / 55 A or 70 A | Easily fulfills the power supply requirements for truck cranes, dump truck electronic controls, and cab air conditioning. |
| Air Compressor | Gear-driven, Single/Twin-Cylinder Air Compressor | Provides abundant air supply for the entire vehicle's air brakes (parking brake), control valves, and air horns. |
| Cooling Fan Drive | Silicone Oil Fan Clutch (Direct drive fan optional) | Automatically detects water temperature to adjust fan speed, reducing engine parasitic power loss. |
| Oil Cooler Type | Integrated Internal Engine Oil Cooler | High heat transfer efficiency prevents engine oil from overheating and deteriorating during continuous uphill heavy loads. |
Fluid Capacity & Maintenance Specifications
| Parameter Dimension | Core Technical Specifications | Industry Analysis & Advantages |
|---|---|---|
| Engine Oil Total Capacity | Approx. 11 L to 13 L (Depending on the specific oil pan model) | Large capacity oil pan effectively extends the maintenance intervals for oil and filters. |
| Recommended Oil Grade | API CF-4 or CH-4 and above | Choose 15W-40 for summer/southern regions or 5W-30 for winter/northern regions depending on ambient temperature. |
| Coolant Capacity | Approx. 12 L (Engine block only, excluding external radiator) | It is recommended to use proper anti-freeze, anti-rust, and anti-boiling coolant year-round. |
| Normal Oil Pressure | 0.30 - 0.50 MPa (3 - 5 bar) | Minimum oil pressure at idle should not be lower than 0.10 MPa; remains stable during high-speed driving. |
| Standard Valve Clearance | Intake: 0.30 mm / Exhaust: 0.35 mm (Adjusted when cold) | Periodic adjustment is recommended (after an overhaul or every 40,000 km of driving). |
| Fuel Filtration System | Spin-on primary fuel filter (with water separator) + secondary fuel filter | Euro 3 injection systems require high fuel cleanliness; regular draining of accumulated water is mandatory. |
