One other quirk of two-stroke diesels is that they aren't lubricated the same way as four-stroke diesel engines. A normal four-stroke engine has separate oil and fuel. You fill up your car with gas, and every once in a while you check the oil and replace the oil.
Two-stroke motors aren't like that. They don't have separate fuel and lubrication systems. Think of a chainsaw; the fuel and lubrication oil are mixed together, and the moving parts of the engine are lubricated using this fuel/oil mixture. This further reduces the size of the engine, but it means that there's a bunch of oil mixed in with the fuel, which tends to produce a blue or white smoke as the motor runs.
2 stroke diesels used in Tanks and APC's has a separate oil sump just like on a 4 stroke, it is not a moped engine. 2 strokes smoke more because of larger injectors and they always have pressure charged intake air by a compressor / Roots Blower. They usually have more torque at low RPM compared to a 4 stroke.
