Engine Specifications:
The 912 series engines are air-cooled, naturally aspirated in-line engines available in 3, 4, 5, and 6-cylinder configurations. They feature direct injection and an advanced injection and combustion system. The engines are designed with a compact structure, high torque at low speeds, and a modular system with a high degree of parts commonality. They are capable of cold-starting under extreme climatic conditions.

Benefits:
The engines offer fast response to load changes, low noise emissions, and reduced operating costs due to lower fuel consumption and extended maintenance intervals. They have excellent smooth-running characteristics, minimal environmental impact meeting EU-RL 97/68 exhaust regulations, and are extremely reliable and durable. The engines are easy to install with an integrated cooling system.

Technical Data:
The engines are available in different models (F3L912, F4L912, F5L912, F6L912) with varying numbers of cylinders and power ratings. The bore/stroke is consistent at 100/120 mm across models, with displacement ranging from 2.83 to 5.66 liters. The compression ratio is 18, with a maximum rated speed of 2500 min-1. Power ratings for construction equipment engines range from 40 to 82 kW, with specific fuel consumption at 225 g/kWh.

Engine Components:
The engines feature an air-cooled system with an integrated axial-flow blower, grey cast iron crankcase, and aluminum single cylinder heads. They have overhead valves, three-ring pistons, and a drop-forged steel crankshaft. The lubrication system includes a forced-feed circulation lubrication with a rotary pump, and the engines have an integrated aluminum cooler.

Dimensions and Weight:
The dimensions and weight vary by model, with the F3L912 being the smallest and lightest, and the F6L912 being the largest and heaviest. The engines are designed with standard flywheels and oil pans.
