Technical Specifications
* Engine type: 4-cylinder, in-line, diesel
* Displacement: 4.4 liters (268 cubic inches)
* Bore and stroke: 105 mm x 127 mm (4.13 inches x 5 inches)
* Compression ratio: 17.5:1
* Maximum power: 100 kW (134 hp) at 2200 rpm
* Maximum torque: 510 Nm (376 lb-ft) at 1400 rpm
* Fuel injection system: Common rail direct injection with electronic control
* Emissions compliance: Tier 4 Final / Stage IV
Design Highlights
* **Advanced combustion system:** The engine features a state-of-the-art combustion system with optimized fuel injection and air flow to ensure efficient and complete combustion, resulting in reduced emissions and improved fuel economy.
* **Robust engine block:** The engine block is constructed from high-strength cast iron, providing exceptional rigidity and durability. It incorporates reinforced main bearing caps and a deep-skirt design to minimize vibrations and noise.
* **Precision-engineered crankshaft:** The crankshaft is forged from high-quality steel and precision-ground to ensure perfect balance and smooth operation. It is supported by seven main bearings for increased reliability and reduced stress.
* **Heavy-duty connecting rods:** The connecting rods are forged from high-strength steel and are precisely machined for accurate piston alignment. They are equipped with replaceable big-end bearings for ease of maintenance.
* **High-performance pistons:** The pistons are made from aluminum alloy and are designed with a shallow combustion bowl to optimize fuel efficiency. They feature integral cooling channels to dissipate heat effectively, reducing thermal stress and increasing durability.
Key Features
* **Electronic engine management:** The engine is equipped with an advanced electronic engine management system that controls fuel injection, air flow, and other engine parameters. This system optimizes engine performance and efficiency while meeting stringent emissions regulations.
* **Turbocharger with intercooler:** The engine utilizes a turbocharger with an air-to-air intercooler to increase air density and boost power output. The intercooler reduces the temperature of the intake air, improving engine efficiency and reducing emissions.
* **Common rail fuel injection:** The common rail fuel injection system provides precise control over fuel delivery, ensuring optimal combustion and minimizing emissions. The high-pressure injection system atomizes the fuel into fine droplets, improving fuel efficiency and reducing noise.
* **Two-stage oil filtration system:** The engine features a two-stage oil filtration system that removes impurities and protects critical engine components. The primary filter removes larger particles while the secondary filter captures smaller contaminants, ensuring clean oil is circulated throughout the engine.
* **Heavy-duty cooling system:** The engine is equipped with a heavy-duty cooling system that maintains optimal operating temperature under various load conditions. The system includes a large radiator, a high-flow water pump, and a thermostatically controlled fan.
