    • An air intake system (20) for a utility vehicle engine (16) is provided. The system comprises an air filter module (21) having a pre-filter (22) upstream of a main filter (24) wherein the pre-filter serves to extract dust from the air stream. The system further comprises a fan module (32) which is dedicated to deliver a scavenging vacuum which sucks said dust through a scavenger vent (28) in the pre-filter. The fan module (34) is secured to the air filter module (21). By providing a dedicated fan for extracting the dust from the system the reliance on the engine exhaust to provide the vacuum is removed. Furthermore, the securing of the fan module to the air filter module reduces the number of components on the vehicle assembly line.
    • 提供一种用于多用途车辆发动机(16)的进气系统(20)。 该系统包括具有在主过滤器​​(24)上游的预过滤器(22)的空气过滤器模块(21),其中预过滤器用于从空气流中提取灰尘。 该系统还包括风扇模块(32),该风扇模块专用于输送清除真空,其通过预过滤器中的通风口(28)吸入所述灰尘。 风扇模块(34)固定到空气过滤器模块(21)。 通过提供用于从系统中提取灰尘的专用风扇,消除了对发动机排气的依赖以提供真空。 此外,将风扇模块固定到空气过滤器模块减少了车辆装配线上的部件的数量。
