text: The higher compression ratio in diesels means they are harder to start, but once they are running the energy expended in compressing air is regained during the expansion stroke when the compressed air is allowed to "spring" back, so the higher compression ratio causes negligible engine braking via energy being lost as friction and heat of compressed air to engine block.
