Abstract
In resent years, higher combustion efficiency and lower emissions are required in engine development and therefore higher combustion control is necessary. To realize higher combustion control in reciprocating engine, cycle to cycle flow rate measurement is important. Especially it is a key factor to control HCCI combustion. Traditional laminar flow meter has a problem with response. However, fast response differential pressure transducer allows cycle to cycle dynamical flow measurement. The availability of Fast-response Laminar Flow Meter on cycle-to-cycle flow rate measurement is shown in this paper.
