Many motorcycles  increased  within past few years, the gas emmited from the motorclyce will be polluted  the population. One of technology that can reduce the emmited gas is using catalytic converter on the muffler. Catalytic converter is a catalyst that can alter or accelerate a matter (chemical reaction) of a carbon monoxide into carbon dioxide. In this research will use two types of catalytic converter that is honey comb and a copper plate. From the test can be seen that the catalytic converter with a honey comb shape better in terms of engine performance than the catalytic converter shaped plate. Compared wihtout any catalytic converter, the highest percentage honey comb catalyst reduce  the power within 0.12 HP, and torque increased to 0.04 Nm. While the highest copper catalyst  that reduce the power within 0.71 HP, and torque decreased to 0.2 Nm.

I. C. Engines consume large amounts of fossil fuel emitting harmful pollutants like carbon monoxide (CO), unburnt hydrocarbons (UBHC), and oxides of nitrogen (NOx). By using a catalytic converter (CC), the carbon monoxide, hydrocarbon emissions can be transformed into less harmful carbon dioxide (CO2) & water vapor (H2O). Currently available CC’s are using costly noble metals like platinum (pt), palladium (pd), rhodium (rh) etc., hence making them expensive. This paper deals with the use of low-cost palletized silver coated alumina as the catalyst element in a CC. In this study, alumina and silver were used in the ratio of 10:1. All tests have been conducted on a stationary S.I. Engine at a constant speed of 1500 r.p.m with and without CC. Also, the performance of the palletized CC in combination with promoters like Bismuth, Cerium and Lanthanum was tested which have shown better results than silver alone as the coating element. It has been experimentally determined that the CO emissions have dropped from 7.25 (% vol) to 3.03(% vol) and the HC values have reduced from 350 ppm to 190 ppm.

Nowadays, more researches focus on protecting the environment. Present investigation concern with the effectiveness of Oxygen Enriched hydrogen- HHO gas addition on performance, emission and combustion characteristics of a DI diesel engine. Here the Oxygen Enriched hydrogen-HHO gas was produced by the process of water electrolysis. When potential difference is applied across the anode and cathode electrodes of the electrolyzer, water is transmuted into Oxygen Enriched hydrogen-HHO gas. The produced gas was aspirated into the cylinder along with intake air at the flow rates of 1 lpm and 3.3 lpm. The results show that when Oxygen Enriched hydrogen-HHO gas was inducted, the brake thermal efficiency of the engine increased by 11.06%, Carbon monoxide decreased by 15.38%, Unburned hydrocarbon decreased by 18.18%, Carbon dioxide increased by 6.06%, however, the NOX emission increased by 11.19%.

Previous Communication

In a previous communication* the authors described a method of measuring rates of reaction of molecules and atoms which were being activated by electron collision in suitably constructed triode tubes. the method has since been extended to study the decomposition of carbon monoxide and its interactions with hydrogen. Carbon monoxide has long been known to undergo decomposition, chiefly into carbon and carbon dioxide in the silent discharge. A mixture of solid oxides containing chiefly C 3 O 2 is always observed. Carbon monoxide and hydrogen yield an even greater diversity of products. Thus Losanitsch and Jovitschitsch and de Hemptinne noted the production of formaldehyde and its polymers and also some formic acid. Slosse and Nowak ¶ and Löb** obtained formaldehyde and methyl alcohol, while the latter also found glycollic aldehyde. M. Berthelot stated that excess of hydrogen favours the production of (CH 2 O) n , whereas excess of carbon monoxide yields (C 3 H 4 O 3 ) n .

The paper studies the influence of shielding gas on the composition and the structure of weld joint metal of 30MnB5 steel applied in essential parts of automobiles and tractors. The welding was performed in inert, oxidizing and reducing atmospheres. It was established that TIG welding with argon used as shielding gas did not provide the required mechanical properties when using conventional welding materials. Carbon dioxide during MAG welding caused partial burning of alloying elements. Carbon monoxide used as shielding gas was proved to form reducing atmosphere enabling to obtain chemical composition close to the base metal composition. Metallographic examinations were carried out. The obtained results provided full-strength weld, as well as the required reliability and durability of welded components and joints.
