    Abstract

    Oxygen-rich combustion air is one of the factors being able to enhance diesel engine performance. The existing air filter can merely adsorb rough particles (such as dust, etc), but it cannot adsorb nano particles (such as nitrogen and H2O). Natural zeolite has an ability to adsorb nano particles. A four-stroke petrol engine performance was successfully enhanced by passing its combustion air on pure natural zeolites. The adsorption capability of the zeolites can still be increased by treating physical-NaOH activation on zeolites. The experiments were performed in a four-stroke diesel engine, single cylinder. From the results, it is found that there is a significant increase of the engine performance at operations using the physical-NaOH activated zeolites. Higher amount of zeolites used led to higher engine performance. Meanwhile, higher engine speed did not always guarantee to give higher engine performance. The highest increase of brake power was 0.1159 kW (5.87 %) while the highest reduction of bsfc was 0.0211 kg/kWh (9,72 %). It was occurred at the use of 200 grams of the activated zeolites. Keywords :oxygen production, adsorbent for nitrogen, activated zeolites.
