    • 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。

    • This disclosure relates to an air cleaner for use in an air-cooled engine including a cooling fan within a fan housing. The cleaner is connected to draw air from the housing, and includes a casing having a side wall, an air inlet opening in the fan housing, an air passage formed within the casing and extending from the inlet along the wall, the passage including a curved portion, and a narrow opening formed in the wall adjacent the curved portion. The curved passage causes dust particles to move by reason of inertia to the radially outer side of the passage and the particles are removed through the narrow opening.
    • 本公开涉及一种在风冷发动机中使用的空气滤清器,其包括在风扇壳体内的冷却风扇。 清洁器被连接以从壳体抽取空气,并且包括具有侧壁,风扇壳体中的空气入口开口的壳体,形成在壳体内并沿着壁从入口延伸的空气通道,该通道包括弯曲的 部分,以及形成在邻近弯曲部分的壁中的窄开口。 弯曲通道使灰尘颗粒由于惯性而移动到通道的径向外侧,并且颗粒通过狭窄的开口移除。
