Effect of fuel-air mixture diluted by inert gas on knock intensity was investigated by using a rapid compression and expansion machine. Dilution of fuel-air mixture decreased knock intensity. As the dilution ratio became high. increase in input heating value did not affect knock intensity too much although it shortened auto-ignition delay. https://www.ngetikin.com/bargain-MLB-Texas-Rangers-Alternate-Away-Jersey-iPhone-14-Pro-Clear-Case-p111023-save-big/
