Atmospheric contains a variety of gases such as 78% nitrogen, 21% oxygen and 1% other gases.This causes incomplete combustion. Because the main composition of the combustion process is fueland oxygen. The use of zeolite physically activated by microwave which can increase the quality ofcombustion air. Zeolite is a type of rock that is capable of absorbing (capturing) molecularparticles or angstroms such as water vapor and nitrogen in the air. So that it will produce a richoxygen in the air when entering the combustion chamber. The performance of a 4-stroke motorcycleengine is good if there is a decrease in fuel consumption, it can increase the acceleration, andreduce exhaust emissions containing CO and UHC. To find out the effect of the zeolite filters onengine performance, an acceleration test of 0–80 km / h is performed. Zeolite is activated using amicrowave with 80% power, activation time is 3, 6, and 9 minutes, with gap of 75%. Then zeolitewas activated with 80%, 60%, and 40% power of microwave using 50%, 75%, and 100% gap(varying the gap arrangement of pellets). When the activation time of the filter is 3 minutes, it takes12.54 seconds to conduct, 6.53% faster, the a 6 minutes activation takes 12.58 seconds and 6.19%faster. The greater the activation power, the better acceleration. In the 80% acceleration test, 50%gap can increase the acceleration by a percentage of 6.16%. Meanwhile, the gap of 75% and 100%it can increase the acceleration by 5.64% and 3.86%.Keywords: Zeolite, physical activation, using microwave, increase acceleration
