"Yes," I replied, "arent you familiar with air cleaners? Car builders for several years bave been using them to prolong the engine's life." "No," the storekeeper admitted, "but I do know from what I've seen and heard that cars nowadays go very much farther before it Is necessary to overhaul the engine I can remember I when overhauling was almost a weekly week-ly routine." So being on my vacation and having hav-ing plenty of time, I told him much about this Interesting engineering development de-velopment "The air cleaner," 1 explained, "is a small device that attaches to the carburetor. It removes dirt and dust before It reaches the carburetor and does its work so thoroughly that damage dam-age from this cause is negligible. However, if the dirt and dust were permitted to enter the engine, It would form on the cylinder walls and becom- Ing mixed with the lubricating oil, serious wear would result Two Kinds of Cleaners. "Two kinds of air cleaners are used on automobiles, the centrifugal type and the 'oil wetted." In the former, dirt and dust are separated from the air by menns of centrifugal force, the principle being exactly the same as that used In the well known cream separator. The latter type 1 a clr- cular can filled with thin copper wire mesh, which Is wettd with oil.

None of these things was necessary; no bearing knocks; oil and gasoline mileage satisfactory. satis-factory. In fact the engine was Just nicely run In. 1 The nlr cleaner, together to-gether with the oil filter, made this possible." |
