rice cleans carbon (Dec, 1950)
rice cleans carbon
RICE is moving out of the kitchen and into the garage. Oldsmobile has developed a new device, the Head-On Carbon Blaster, which uses rice under air pressure to clean engine combustion chambers through their spark-plug openings.
Ten to 20 pounds of specially prepared rice, above, are poured into the perforated hopper of the Carbon Blaster, the mechanic inserts the nozzle into the spark plug port, right, and turns the air control valve to “blast.” The rice under pressure chips off the carbon deposits and thoroughly cleans all surfaces. Above right are two combustion chambers in the same engine—the one at left after treatment and the one at right before treatment.
