Cleanliness and extraction test: fuel hose used for liquid injection hose C after 24h parked emptied and cleaned inner wall C liquid. Collection C liquid injection and rinse the car with a hose outlets, the insoluble impurities filtered out, Zigui car with a hose outlets, dried, and weighed the weight of insoluble impurities come to the surface area per unit hose on the amount of impurities or contaminants of maximum Size indicates cleanliness; the filtered solution was evaporated, dried, weighed obtain soluble matter weight. With methanol from the filtrate was evaporated to dryness resulting wax was extracted and the resulting methanol extract was evaporated to dryness to give wax substance called weight.
