Assume aviation exhaust temperatures similar to diesel. But about a foot away from the exhaust stack, the temperature drastically drops to around 400-500 F (260C). This is due to looses from mixing and radiation.
With landing gear that far away (looks like several feet from pic), temperature from exhaust should not be a problem at all, even for slow speed taxi. At take-off speeds, the mixing is significant.
I think land based diesel engines exhaust temperature range form 400 - 450 Deg C for small engines say < 1 MW to 350 Deg C for laregr engines say 2 - 3MW and above. I gues petrol engines would be in the same range.
But diesel engines are hardly ever used in aircraft. To the best to my knowledge the only success story of diesel engines used on aircraft is JU 88. Please confirm
