Professional team
As Caterpillar's classic medium-sized power platform, the 3116 engine has become an ideal choice for space-constrained scenarios with its compact cylinder structure (length × width × height: 1.2 × 0.8 × 1.1 meters) and lightweight design (dry weight is only 520 kg).
Fast delivery
Its direct injection fuel system achieves an 18% increase in fuel atomization efficiency through a high-pressure mechanical pump, showing a low fuel consumption advantage in excavators, small and medium-sized loaders and other equipment (full load fuel consumption rate ≤ 220 g/kWh).
Performance characteristics
High-efficiency power: The Caterpillar 3116 engine can exert higher power and torque under low speed and high load conditions, improving the overall power performance.
Fuel economy: Advanced combustion chamber design and fuel injection system make fuel combustion more complete, reduce fuel waste and emissions, and improve engine efficiency.
Product advantages
Durability: The use of high-strength materials and wear-resistant parts makes the engine have a longer service life.
Strengthened structural design: The use of high-strength vermicular graphite cast iron cylinder block and forged steel crankshaft has exceeded 15,000 hours (when the operating load rate is ≤80%) after 20,000 hours of bench durability test.
In response to the high-frequency start-stop requirements of construction machinery, CAT 3116 uses reinforced crankcase and nano-coated piston ring technology to effectively reduce idle wear. The unique two-stage air filter system can adapt to dusty environments and cooperate with intelligent temperature control fans to maintain cooling efficiency under high temperature conditions. This model is equipped with a SAE 3 flywheel interface as standard, which supports seamless matching with the Allison 3000 series gearbox, providing a flexible power solution for special vehicle modification.
