Excavator Engine Fuel Injection Pump 101062-8520 212-8559 287-0089 for 3066 Diesel Engine

101062-8520 Fuel Injection Pump

High-pressure fuel delivery: Pressurizes diesel fuel to 1,800–2,000 bar (model-specific) and distributes it to the 3066 engine’s injectors, ensuring sufficient fuel pressure for complete combustion under medium-heavy load conditions (e.g., excavator digging, material loading).
Precision fuel metering & injection timing: Calibrated to match the 3066 engine’s combustion cycle, precisely controlling fuel injection quantity (0–180 mm³/stroke) and timing (±0.5° crankshaft angle) to optimize power output and fuel efficiency.
