36、意图 通过“可变进气系统”(VIS) 可增强其性能，无论 Freelander 遇到何种条件，在所有转速范围内，该系统都能不断地进行自身调整，以获取最佳 的性能。（可变进气系统 ：VIS Variable Intake System） 另一个特别有效的功能是“进气岐管”和加压共振的组合。它可在低速下 提供强大的扭矩。Illustration 40进气歧管系统KV6-进气歧管系统 原理：空气动力效应，包括气流惯性效应和气流波动效应。 结构形式包括：长进气歧管，设置动力腔，谐振腔及采用可变惯性充气系统。 气流的惯性效应:指在进气歧管内高速的气流由于具有一定的惯性，在气缸进气行程进行到活塞到达下止点

37、后仍可利用进气气流的惯性继续充气一段时间，以增加充气量。适当增加进气歧管的长度，可以增大气流的惯性效应的效果。例如：长大弧形的进气歧管。 气流波动效应:指由于各缸进气过程具有间隙性和周期性，导致进内产生一定幅度的气流往复反射。如果进能利用共振后的 的谐振腔。波动。这个波会沿着进以音速，并在管内的形状有利于这一波的反射并产生一定的共振，就波提高进气量。例如：在进气歧管旁边设置于进相通 空气动力效应对充气效率的影响取决于进的长度和形状。因此，不同长度或不同形状的进，因空气动力效应的效果不同，其充气效率随发转速的不同而变化的特性也而成的。全相同。可变惯性充气系统就是利用这一原理设计Illustration 41KV6-进气歧管系统进气歧管腔是一块模塑物，它安装在进气歧管上，并以4个螺丝固定。3 个”O”型圈和3个模具密封圈都位于凹进处，在进气歧管腔和进气歧管之间。这种铝合金的进气歧管都用衬垫与每个气缸盖密封在一起，并且在每个进气歧管腔均用O型圈和密封圈来密封。对进气歧管腔的起重要作用的一个单独的节气门体，它提供空气进入分 开两条次级管道中的”Y”型的块内，次级管道连接两个主腔，每条管道连接每边的3个气缸。在高压腔关闭的末端是一个平衡阀
