You are not an aircraft pilot it seems, me if ...
Being a pilot does not mean having a good knowledge of aircraft structures as well as engines, propellers, etc.
I know many pilots who never unscrew a candle to remove the pellets from the 100LL,
and even that some do not know how to blow tires.
An airline pilot with 10000 hours may never have put fuel on an airplane.
I know others who fly without a patent and who dismantles their entire engine
Back to our aircraft diesels
Several diesel are currently on aircraft engines, more in France, in America rather rare.
But the question of oil and temperature, for small planes which walks most of the time at between 2000 feet and 8000 feet
the temperature does not affect much, despite it sometimes -25 at home.
the oil added to the kerosene is only for lubricating the injection pump on mechanical pump models, the Thielert electronic injection engine does not need to add oil in the kerosene, it is the engine that is encountered on planes currently certified, and which makes long discussions each time there is an engine failure often electrical cause ..
For amateur builders, they prefer to keep mechanical pump technology

and the prototypes "Zoche
To my knowledge the Zoche 2 stroke has not been placed on any aircraft and the designer does not want to sell it (I know it for having made steps to buy one) Yet every year in Oshkosh (the aircraft manufacturers' check ) it has a kiosk with a static engine .. most of the current diesel engines, on aircraft are 4 stroke (there was the Junkers Jumo an engine in the 40s)
the rare two times little known on planes
For the Wilksch Wam160
89hp at 2300rpm 21litres of diesel
For a Lycoming o-290 D2
87 hp at 2200 rpm 24 liters (modified to 20 liters)
and it runs on automotive fuel 7,5 compression ratio
