and the larger theĬoil wire diameter is used, the higher the temperature Temperature of 648.22 ° C, the number of turns (20) theĪverage temperature value is 651.11 ° C. The number of turns (25) produces the lowest average The highest average temperature value of 681.11 ° C, while Number of turns that vary, where the number of turns (30) has To is 20 turns, 25 turns, 30 turns, and a wire diameter of 1 mm,ġ.5 mm and 2 mm. The method used by testing using the number of turns referred TheĪim is to determine the effect of the number of turns and wireĭiameter on the temperature produced in the metal smelter. This paper discusses the role of the number of turns and theĭiameter of copper wire on metal melting temperature. The results of the research data analysis can be concluded that using HCS produces better exhaust emissions, CO has decreased by-29.5%, HC has decreased by-60.42%, CO2 has increased by 14.81%. The data obtained is in the form of CO, HC and CO2 gas emissions. The fuel flow from the heating pipe is flowed to the intake manifold using a heat resistant hose. The heating pipe is attached to the exhaust by using a copper capillary pipe. The fuel tank is connected to the heating pipe using a pipe made of heat resistant hose. The test method uses a gas analyzer type HG-520, connected to the vehicle exhaust gas line. The purpose of using the Hydrocarbon Cracking System (HCS) is to reduce exhaust emissions. Meanwhile, the concentration of CO gas in the air varies, depending on the density of vehicles using gasoline. The paper discusses the role of the hydrocarbon cracking system on gas emissions of gasoline vehicle, where CO gas emissions greatly affect human health. Optimization of tensile strength and time of 18.78 MPa and 0.018567 Joule/mm 2 respectively, these values are obtained from the combination of an anvil plate temperature of 120☌ and hot hot air flow of 200☌. The results of research, it was found that the temperature of the foundation plate and the temperature of hot gun hot air flow during the hot gas welding process had an effect on the tensile strength and the hit of the HDPE welding joint. To obtain data, it was carried out by tensile and hit tests using standard specimens, respectively ASTM D 638-03 and ASTM D 6110. The method uses the hot gun setting and the base plate temperature during the welding process (30☌, 60☌, 90☌ and 120☌), as well as the hot air flow temperature of the hot gun (250☌, 300☌, and 350☌). The research objective was to determine the role of the foundation plate temperature on the tensile strength and the impact on HDPE sheet welding using hot gas welding. HGW is a welding process for plastic materials, but it is known that plastic materials have poor heat conductivity. In the industrial world, the joining of two or more plastic parts can be done with plastic welding technology, one of the methods of plastic welding is hot-gas welding (HGW). Plastic material failures such as fractures or cracks can be repaired by joining. When the throttle is wide open, but the intake valve's movement is fast, the incoming air becomes not optimal so that the air trapped in the intake manifold increases, and the pressure rises. It happens because of the faster engine speed in line with the rapid movement of the intake and exhaust valves. At 5000 rpm engine speed, the intake manifold pressure again increases to an average of 26.1 Kpa. At 4000 rpm rotation condition of intake pressure rises to an average of 25.5 Kpa, this is due to the condition of the engine that requires quite a lot of air, but the movement of the suction valve is faster so that the air entering the combustion chamber is blocked and causes an increase in the amount of air in intake chamber. Whereas at engine speed 2000 rpm and 300 rpm shows the intake manifold pressure is low, this is due to the higher engine vacuum, the more air demand so that intake pressure decreases. At 1000 rpm rotation, the average condition shows intake pressure at 24.3 Kpa. shows variations in engine speed affecting the intake manifold pressure conditions. The relationship between Engine Speed Against Intake Manifold Pressure Figure 6.
