Thermal Efficiency for Diesel Cycle. Since Carnot’s principle states that no engine can be more efficient than a reversible engine (a Carnot heat engine) operating between the same high temperature and low temperature reservoirs, the Diesel engine must have lower efficiency than the Carnot efficiency.A typical diesel automotive engine operates at around 30% to 35% of thermal efficiency.
