A method of lowering fuel consumption and NOx levels in a two-stroke diesel engine having at least one piston disposed in at least one combustion chamber comprises the steps of providing a compression ratio within the combustion chamber between about 16.5:1 to about 19:1, providing a ratio of peak pressure to compressed pressure within the combustion chamber below about 1.4; and providing a trapped air charge density within the combustion chamber of at least 2.77 kg/m3. Combustion within the diesel engine results in NOx levels in exhaust gases below a predetermined amount and fuel consumption below a predetermined amount.
