Study of Development of Jade Nephrite to Reduce Toxic Exhaust Gases in Motorcycle Pipes.

Abstract

This research has the following objectives: 1. To design and build a catalog converter  using nephrite jade constituents 2. To determine the performance of the catalytic converter using nephrite jade by studying the feasibility of using jade as an ingredient in the construction of catalytic converters. The finely crushed nephrite jade is mixed with clay compound at a ratio of 70:30 to form a catalytic nephrite jade converter. Freire Soil extrusion is filtered so that the grain size is similar. when forming to size and burned at room temperature to 925 degrees Celsius, totaling time 5 hours, resting in the oven 5 hours, then burning with temperature 925 degrees Celsius to 1,200 degrees Celsius for another 5 hours, installed in the Yamaha motorcycle exhaust pipe. GRAND FILANO model, 125 cc engine to measure with an exhaust gas analyzer, Gas Analyzer, test engine rpm 1,500 rpm, catalytic set nephrite jade converter It is designed and built to have better carbon monoxide (CO) filtration performance compared to not installed. Carbon monoxide (CO) can be reduced from an average of 0.178% to 0.012%. And the hydrocarbon (HC) gas value was reduced from an average of 51.6 ppm to an average of 19.8 ppm, or a 38.7% reduction. 0.45% to 0.038% and can reduce hydrocarbon (HC) gases from an average 61.2 ppm to an average of 38.4 ppm, a 62.7% reduction in emissions from motorcycle exhaust pipes. The engine is 4,500 rpm at 0.381% and the average with the lowest average carbon monoxide is Engine rpm 6,500 rpm is at 0.005%, which can reduce the value by 0.376%, while the value at engine rpm 4,500 rpm is 0.012%, which is the middle of all 3 Engine rpm. There is an additional test at 2,000 engine rpm, the average carbon monoxide (CO) is not installed and installed from 0.19% to 0.013%, can reduce the value by 0.17%, hydrocarbon (HC) value from 53 ppm. to 21 ppm. Can reduce the value by 32 ppm. And testing at 2,500 rpm engine rpm, average carbon monoxide (CO) in case of not installing and installing from 0.21% to 0.015%, can reduce the value by 0.19% Hydrocarbon (HC) value from 56 ppm. to 23 ppm. . Can reduce the value by 33 ppm. in low catalytic engine cycles converter using nephrite jade can reduce the amount of exhaust gas.
