Non-air working fluids for closed-cycle diesel engines

Air, which is 79% nitrogen, is the working fluid in a conventional diesel engine. The nitrogen is discarded after use, along with combustion products. In closed-cycle diesel engines, exhaust gas is re-circulated after combustion-produced by-products are separated and removed from the inert working fluid. Now, the working fluids need not be nitrogen, but may be argon, helium, or carbon dioxide. Each of these gases has its own peculiar characteristics that affect the performance of compression ignition engines. The analyses show what performance trends may be expected when nitrogen is replaced with argon, helium, or carbon dioxide as the inert working fluid in closed-cycle diesel engines.
