COnstant gas velocity
COnstant gas velocity
(OP)
THanks in advance,
Is any work being done on technology to maintain a constant velocity of charge as air/fuel pases valves on an intake charge. The advantages on combustion chamber design are well known, and attempts to minimize the turndown ratio along the whole rpm range have been feeble thus far.
Is anyone pursuing constant velocity charge?
Regards

THanks. I'll review that SAE paper. I guess I don't understand. When the gas flow is decelerated during the exhaust cycle, it has to be re accelerated again..in addition, the cross section of the intake runner is too big at low flow (resulting in low velocity) or too small at high flow (resulting in DP loss).
I know the Japanese have the two runners to select the appropriate cross section (thus approximating constant velocity)but this seems a bit awkward.
Wouldn't a
