Jet engines aren’t actually Diesel engines though. They don’t use a Diesel cycle but a Brayton cycle. The principles are different - a Diesel engine works by having a fuel which ignites when compressed in a confined space, while a Brayton engine specifically avoids that and ignites its fuel via a heat source. But the fuel known as “Diesel” is pretty close to jet fuel, both of them being almost kerosene, so it should burn just fine in a jet engine.
