Abstract
The invention relates to a quick-response variable intake system for internal combustion engines and a control method of the quick-response variable intake system, which belong to the field of variable valve control technology for internal combustion engines. The variable intake system is arranged in an intake passage in front of an intake valve, and mainly comprises a disk, a driven shaft, a quadrant and the like. The driven shaft is in gear type engagement with the quadrant, and the disk is fixedly inserted in a driven shaft slot. The quadrant is directly driven by a rotary driving mechanism or indirectly driven by a straight motion type driving mechanism through a rack. By controlling the opening and closing states of the disk, control methods for the disk, such as full opening, advanced closing, delayed opening plus advanced closing and repeated opening, are realized to meet the requirements of different working conditions of an internal combustion engine on intake and intake flow, and thereby the purpose of increasing the performance of the internal combustion engine is achieved. By adjusting the maximum running angle of the disk and the transmission ratio of a pair of engaged gears between the driven shaft and the quadrant, a conventional driving mechanism can meet the driving requirement of the system, the position of each part of the system can be adjusted flexibly, and thereby the adaptability of the system is increased.
