DEUTZ - 912 air cooled diesel engines
These are the characteristics:
Air-cooled 3-, 4-, 5-, 6-cylinder naturally aspirated in-line-engines.
Advanced injection and combustion system.
PTOs via gear, V-belt and crankshaft.
Extremely compact design.
High torque at low speeds.
Modular system with single cylinder arrangement and high degree of parts commonality.
Customized component system with many different peripheral parts.
Cold-starting ability even under extreme climatic conditions.
Cooling system: Air-cooled with integrated axial-flow blower
Crankcase: Grey cast iron
Cylinder head: Aluminum single cylinder heads
Valve arrangement/timing: Overhead valves in the cylinder head, one inlet and one exhaust valve per cylinder,
actuated from gear-driven camshaft via tappets, push-rods and rocker arms
Piston: Three-ring piston: two compression rings and one oil scraper ring
Piston cooling: Oil spray via nozzle
Crankshaft: Nodular cast iron with integrated counterweights
Connecting rod: Drop-forged steel rod, diagonally split
Main and big end bearings: Ready-to-install bi-metal plain bearings
Camshaft: Steel, seated in bi-metal bearing on the blower side
Lubrication system: Forced-feed circulation lubrication with rotary pump which feeds lubricating systems
Engine oil cooler: Integrated aluminum cooler
Oil cooler thermostat: Oil cooler flow thermostatically controlled on engines with heating system
Lube oil filter: Paper-type micro-filter as replaceable-cartridge full flow filter
Injection pump/governor: In-line injection pump with mechanical centrifugal governor
