Unformatted text preview: BSE 2484 Lab 10 (Intake & Exhaust Systems) STATION # 1 (Small Engine Air Cleaners) Types of Air Cleaners: Dry type- work by passing air through multiple layers of cloth or felt. Dry element type use a pleated filter element. The large surface area of the filter traps the fine particles while allowing clean air to move through to the engine. Viscous-impingement type- air flows through an oil impregnated media such as metal wool or foam. Dirt is trapped by the oil on the surface of the media which must be cleaned often Oil bath type- air passes through an oil filled chamber and then through a porous media saturated with oil. Dirt is trapped by the oil and washed to the bottom of the oil cup. At this station there are three types of air cleaners used on small engines! Name each type of air cleaner represented at this station. Blank # 1 Can these types of filters be cleaned and reused? Blank # 2 BSE 2484 Lab 10 (Intake & Exhaust Systems) STATION # 2 (Ford Air Cleaner) Pre Cleaners: Pre-cleaners remove larger particles from the air before it enters the main air-cleaner. Pre-cleaners - remove about 80%- 90% of the particles from the (allowing longer service intervals in the main air cleaner) Pre-cleaners may separate units or integrated with the air cleaner assembly. Most pre-cleaners use a rotating cyclonic motion of the air spins the particles out of the air with centrifugal force. The particles are collected in the dust cup (which should be serviced daily) Types of Air Cleaners: Dry type- work by passing air through multiple layers of cloth or felt....
