It's the same thing! CI stands for Compression Ignition, the formal name. Diesel was the its inventor.

Only if the engine was designed to run on diesel.
A standard 20 to 1 otto cycle is used for the petrol and diesel cycles for diesel engines. It is higher than gasoline engines due to the way diesels burn and compress fuel.

The 4 stroke or 4 cycle engine was invented in 1876 Nicholas Otto in Germany. This is the earliest 4 stroke and is commonly called the Otto cycle engine. The Diesel 4 stoke was invented in 1893 by Rudolph Diesel in Germany.
the difference is the heat addition type In Otto Cycle the heat addition is Isochoric ((constant volume)) In Diesel Cycle the heat addition is Isobaric ((constant pressure))
Dr. Rudolph Diesel first worked on the Diesel cycle using powdered coal dust on a slow speed two stroke engine. So the Diesel cycle came first and later developments led to Diesel engines. Sadly, Dr. Diesel committed suicide by jumping from a boat.
All kinds like 2 cycle, 4 cycle, gasoline, diesel, propane, natural gas, electric,
Both a great deal and very little at the basic operation level.Most current automotive diesel engines are Turbo charged, four cycle direct injection designs with high pressure common rail injection systems.Most North American Locomotives are two cycle turbo charged direct injection engines.Most Locomotives are still using the old style mechanical injection pump or unit injectors. (depending on manufacturer)
A 4-cycle engine completes four steps (intake, compression, power, exhaust) in one cycle, while a 2-cycle engine completes these steps in just two cycles. This results in differences in efficiency, power output, and maintenance requirements between the two types of engines.
