WebFeb 18, 2024 · Due to increasingly tighter emission limits for diesel and gasoline engines, especially concerning particulate matter emissions, particulate filters are becoming indispensable devices for exhaust gas after treatment. Thereby, for an efficient engine and filter control strategy and a cost-efficient filter design, reliable technologies to determine … WebWe’ll use a 3.0L engine and make some assumptions: At 100% volumetric efficiency (VE) and WOT at 700 rpm this 3.0L engine could theoretically flow: 700 ÷2 x 3.0L x 1.18 grams per liter ÷60 seconds = 20.7 grams per second. Actually, at this rpm most engines are only 50% volumetrically efficient.
