Intake Equipment on Vehicular Diesel Engines and Effects on Engine Behavior,
Abstract
The transition to direct injection combined with the spin of the air around the cylinder axis posed new problems in the optimization of the charge cycle. The spin of the air must be achieved during the intake process. The shapes of the intake channel required for this are in contradiction to the first goal which was mentioned, the raising of the charge mass. The effects of the intake manifolds on the charge cycle can be divided into the following groups: (1) utilization of the low-pressure wave produced by the intake process for cylinder filling; (2) utilization of the high-pressure wave at the end of the intake process for modulation of the following intake process; and (3) utilization of the resonance phenomena in the gas column produced by the pulsed mode of operation.
