intake manifold
4.This article analyses the experimental results of the flowing characteristics rand the flow velocity distribution of the intake manifold of WH492 gasoline engines and discusses the way to improve the performance of the intake manifold, thus furnishing an important basis to designing a high performance intake manifold.
5.The factors influencing the intake air factor such as the intake manifold structure parameters: length, diameter and the volume of steady-pressure case were analyzed in order to increase intake efficiency. A specialized intake manifold for the multi-point injection electronic control system was designed and matched with the original engine according the requirements of assemble and techniques.
6.The measurement was carried out by the way of motoring the engine under hot condition and collecting pressure waves ,speed waves at measured section of intake manifold and compression pulse signals inside the cylinder during intake process by using a ICE data analysing system, then the flow coefficient at intake valve seat was calculated with a computer.
