Abstract

The current technology applied to motorbikes is growing, so that it can improve the performance of fuel injection systems that can be controlled electronically by the Engine Control Unit (ECU) with sensors and actuators. ECU is currently produced by an Indonesian racing company other than a motorcycle manufacturer, the Programmable ECU which can change Ignition Timing (ignition time) with the aim of improving engine performance. That way it is necessary to do research that aims to determine the ignition time in the ECU program for torque and motor power of 4 steps. To simplify the implementation, the results of tables and graphs can be analyzed. The effect of standard ECU ignition time at 5 ° before TDC produces maximum torque of 14.86 Nm at 7500 rpm engine speed and 16.9 maximum power at 8500 rpm engine speed. The engine circulates 7500 rpm mapping ECU 1 torque is increased 3% to 15.25 Nm and power rises 3% to 17.4 HP on the 8750 rpm engine. After mapping again to ECU 2 and a 3% increase in torque and 4% power compared to the use of standard ECU ignition time. The resulting torque ECU maps 2 by 15.29 Nm at 7500 rpm engine speed and produces a maximum power of 17.6 HP on the 8750 rpm engine. At ECU 1, mapping with the highest ignition time at 32 ° before the top dead center is carried out. In mapping ECU 2 uses the ignition point time at 35 ° before the top dead center.

Abstract

Turbo cyclone merupakan suatu alat yang membentuk lingkaran mirip baling-baling dengan beberapa sirip statis. Tujuan dari penelitian ini adalah mengetahui pengaruh dari penambahan turbo cyclone sudu 5 dengan kemiringan 50°, turbo cyclone sudu 5 dengan kemiringan 60o dan turbo cyclone sudu 5 dengan kemiringan 70o terhadap unjuk kerja motor bensin yaitu torsi, daya dan emisi gas. Metode penelitian yang digunakan adalah metode eksperimental dimana metode yang digunakan untuk menguji suatu perlakuan atau desain baru dengan cara membandingkan hasil sebelum perlakuan dengan hasil sesudah perlakuan sebagai pengontrolnya. Hasil penelitian yang didapat menunjukan adanya perbedaan dari unjuk kerja yang dihasilkan yakni hasil pengujian torsi yang terbaik pada pengujian torsi menggunakan turbo cyclone sudu 5 dengan kemiringan 50⁰ tanpa menggunakan fiter udara dengan nilai torsi rata-rata sebesar 9,38 N.m torsi maksimal sebesar 11,11 N.m pada putaran 3500 rpm dengan penurunan -5,76 %. Sedangkan hasil pengujian daya yang terbaik pada turbo cyclone sudu 5 dengan kemiringan 50⁰ tanpa menggunakan filter udara dengan nilai daya rata-rata sebesar 6,08 HP dengan daya maksimal sebesar 7,59 HP pada putaran 5500 rpm dengan penurunan -7,12 %. Sedangkan hasil pengujian CO yang terbaik pada turbo cyclone sudu 5 dengan kemiringan 70⁰ dengan menggunakan filter udara dengan nilai CO rata-rata sebesar 0,72 %, CO minimal 0,28 % dengan penurunan -63,6 %. Sedangkan hasil pengujian HC yang terbaik pada turbo cyclone sudu 5 dengan kemiringan 60⁰ tanpa menggunakan filter udara dengan nilai HC rata-rata sebesar 61,2 ppm, HC minimal 34 ppm dengan penurunan -38,8 %.

Abstract

Iron-based production machine components are chosen to support productivity. Steel is a metal material that is easily found on the market, but it has not fulfilled the desires of consumers in the market. This steel can be hardened by heat treatment (heat treatment). The surface treatment process is carried out to obtain the desired hardness, this can be done by increasing the carbon (C) element in the steel material, the carbon content in the standard steel structure is 0.3% - 0.59% the carbon content will have an effect. on hardness, one way to increase the element carbon (C) in steel and increase the hardness on its surface is by carburizing. This research will examine the hardness level of low carbon steel by using a pack carburizing process with different times of 2; 2.5 and 3 hours and the quenching process with pure water media.. The purpose of this study was to determine the effect of holding time on the pack carburizing process with coconut shell charcoal - barium carbonat on the hardness value of ST 42 steel. Besides that for effect of holding time on the pack carburizing process with coconut shell charcoal on the microstructure. There are differences in the surface hardness and microstructure values ​​ before and after the carburizing process. Where the highest hardness value occurs at a holding time of 3 hours with a hardness value of 872.9 HVN or an increase of 382% of the raw material and is supported by the dominance of the martensite phase which is more and more evenly distributed. Compared to the ST 42 steel raw material before the pack carburizing process was carried out, the hardness value was 174.8 HVN. A dominant microstructure consisting of a ferrite phase and a little bit of pearlite dominance.
