These engines compress only air (or air combined with exhaust gases) during the intake stroke to achieve high efficiency and compression.
Internal combustion engines generate power by burning a fuel-air mixture in an enclosed space, creating high pressure that pushes a piston down, which in turn rotates a crankshaft. ENGINES & TRANSMISSIONS V0.1.2.32S 1.46
Improved fuel-air ratio controls and advanced spark timing enhance efficiency in spark-ignition engines. These engines compress only air (or air combined
