Modifications, which serve the technical improvements, are reserved.

• Aircooled 2-cylinder fourstroke Diesel engine.

• Vertical cylinder.
• Crankcase made of alloy, pressure diecasting, parted, vertical in-line cylinders,
grey cast iron.
• Single cylinder heads of light alloy.
• Three-slide bearing crankshaft with solid-forged counterweights.
• Valve control by rocker, push-rods and tappets.
• Pressure circulating lubrication system with replaceable filter in main flow.
• Blower fan charging alternator integrated in the flywheel.

Characteristics

• Denoised: Due to constructional measure the noise emission has been reduced
to a minimum
• All purpose industrial Diesel engine.
• Low weight due to design of alloy.
• Low fuel consumption due to direct injection and multihole nozzles.
• Favourable exhaust emission values below limits of EPA / CARB.
• Robust, and longe life-engine.
• Low repair cost due to single cylinders and single cylinder heads.
• Unusual reliability - because no V-belts.
Engine Dimensions (mm)
type
• Easy to service - automatic injection pump bleeding.
