Abstract

The research method used is an experimental method to determine the effect of Water Methanol Injection on power and torque in Diesel Engines. The test used a four-wheeled motor vehicle type Elf Long 2771 CC engine with the fuel used Diesel B30, with three variations in WMI percentage, namely 10%, 30% and 50% without Cetane Booster and with a booster. The tests carried out were Power and Torque Tests, with maximum results at 2500 RPM Power at a WMI percentage of 30% with the addition of a 150ml booster of 77.19 and Torque of 234.43. Testing was carried out at 1500 to 2500 rpm with 500 rpm increments using a dyno test tool. To process data using Two Way Anova or commonly called 2-way Anova. So, it can be concluded that the use of a mixture of methanol and water increased power and torque, although not too big, whereas adding a booster of 150ml had a big influence on the power and torque test results. Metode penelitian yang digunakan adalah metode experiment untuk mengetahui pengaruh Water Methanol Injection pada daya dan torsi pada Engine Diesel. Pengujian menggunakan kendaraan bermotor roda empat jenis mesin elf long 2771 CC dengan bahan bakar yang digunakan Solar B30, dengan tiga variasi presentase WMI yaitu 10%, 30%, dan 50% tanpa Cetane Booster dan dengan booster. Pengujian yang dilakukan adalah Uji Daya dan Torsi, dengan hasil maksimal pada Daya RPM 2500 pada presentase WMI sebesar 30% dengan penambahan cetane booster 150ml adalah 77,19 dan pada Torsi sebesar 234,43. Pengujian dilakukan tiga kali percobaan disetiap RPM dan setiap konsentrasi pada rpm 1500 sampai 2500 rpm dengan kenaikan 500 rpm menggunakan alat dyno test. Untuk mengolah data menggunakan Two Way Anova atau biasa disebut dengan Anova 2 arah. Maka dapat disimpulkan bahwa penggunaan campuran methanol dan air pada daya dan torsi mengalami kenaikan jika kadar air lebih tinggi, sedangkan dengan penambahan booster sebesar 150ml memiliki pengaruh yang besar pada hasil pengujian daya dan torsi.

Abstract

This study discusses the cooling of water with a system of spraying it into the free air. The energy source to drive the pump uses energy from sunlight. This research is to solve a problem in an area where it is difficult to get water so that the water for the cooling process must be cooled so that it can be used for the next process. The second problem is that the electrical energy is very minimal, so you have to use other energy that can be used for the cooling process. The process of cooling the water spray system into the air was chosen to solve this problem. The tools used in this study were a 600 Wp solar cell, a 300 W water pump and a spray pipe. The research was conducted during the dry season in August. The research results show that the temperature of the water in the pool is not homogeneous the deeper the water in the pool the lower the temperature. The higher the pool water temperature, the longer the cooling time will be. The greater the pump discharge, the faster it will take to cool the pool water. Solar energy is able to supply energy to drive pumps with pool water temperatures up to 45 C. This cooling system can be used at night because it is equipped with batteries. The results of this research can be used and developed to create a larger system. This cooling system does not cause any impact on the environment because the energy source is from sunlight which is environmentally friendly.

Abstract

With increasing public awareness of environmental pollution, especially air pollution, especially CO and HC, the public's interest in reducing the rate of pollution is increasing. Therefore, the aim of this research is to find breakthroughs to help reduce air pollution by using cheap materials. This research is experimental research or experimental research. Research was carried out on trials of making a catalyst from copper material shaped like a wasp's nest. The copper plate is cut to size and folded like a wasp's nest. Data is taken from the nominal numbers printed on the Gas Analyzer monitor, by directly recording each engine rotation starting from idle, 1000, 2000, 2500 and 3500 rpm. The fuel used in this test uses pertalite and Pertamax as a comparison. The engine used has a capacity of 125cc. In this research, the material used was copper plate with a thickness of 0.9mm with a distance between fins of 4mm. The variations in catalytic length are 70mm, 90mm and 110mm. The catalytic shroud uses a standard 2009 Supra-X 125cc exhaust that has been modified internally to make room for the copper plate catalyst. The results taken from this research are the reduction in CO and HC levels in two-wheeled vehicles with an engine capacity of 125cc using a catalyst with a length of 110mm, where this reduction is 70% for CO and 24% for HC, respectively. Meanwhile, the lowest is using a catalyst with a length variation of 70mm with a yield of 8% for CO and 6% for HC.
