Abstract

One of the efforts to decrease exhaust gas emission from four stroke gasoline engine is using cuprum (Cu) coated mangan (Mn) as active metal catalyst to reduce CO, HC and NOx emission. It is placed in exhaust system that is called catalytic converter.The experiment was carried out at Fuel and Internal Combustion Engine Laboratory Mechanical Engineering Departement ITS. In this experiment Honda Karisma X 125D engine was used. The test method is done by velocity gradient at full load (full open throttle valve). The test was carried out by comparing standard engine experiment and engine experiment with catalytic converter on exhaust system. The type of the test is desk test. Data analysis is done by using descriptive methods. The analysis shows that cuprum (Cu) coated mangan (Mn) as catalytic converter with 110 gr Cu + 90 gr Mn catalyst mass decreases vehicle emission that the greatest CO emission decrease at A/F 15 or exhaust gas temperature 273-340°C is up to 96,36%.

Abstract

The use of catalytic converter that placed on vehicle exhaust system can decrease exhaust gas emission consentration from four stroke gasoline engine. From previous research with using chrom (Cr) coated brass (Cu+Zn) as catalytic converter can reduce CO, HC and NOx emission. But, the use of catalytic converter on vehicle exhaust system also influent engine performance. Purpose of this research is to know influent of the use catalytic converter on Toyota Kijang Type 4K exhaust system to torque and engine power.The experiment was carried out at Automotive Laboratory PPPGT/VEDC Malang. In this experiment Toyota Kijang Type 4K series KF20 engine was used. The test method is done by velocity gradient at full load (full open trottle valve). The test was carried out by comparing standard engine experiment and engine experiment with catalytic converter on exhaust system. The type of the test is desk test. Data analysis is done by using descriptive methods. The analysis shows that chrom (Cr) coated brass (Cu+Zn) as catalytic converter increase engine torque is up to 2,34% at 1750 rpm and lower engine torque increase is up to 0,09% at 2750 rpm. The greatest engine power increase is up to 2,35% at 1750 rpm and lower engine power increase is up to 0,09% at 2750 rpm.

Abstract

The aims of this experiment are firstly to conduct a catalytic converter secondly, to find out to what extend copper (Cu) as catalyst is efficient. To measure the concentration of carbon monoxide (CO) and hydrocarbon (HC) on frame there are two conditions  required. First is when the standard condition, and second is when Cu catalytic converter is applied using gas analyzer. This experiment results in the fact that the use of Cu catalytic converter reduces the production of CO and HC of pertamax automobile.
