Abstract

This study examines the Ignition characteristics of blended fuel droplets with crude coconut oil and rhodium liquid as a liquid metal catalyst. The ignition behavior was observed by igniting the oil droplet on a junction of a thermocouple, and the droplet evolution recorded with the high-speed camera. The results show that the addition of a liquid metal catalyst successfully reduces the molecular mass of the triglyceride and weakens the bonding force between the carbon chain, and therefore the viscosity and flash point decreases. Moreover, the addition of liquid metal catalysts increased the reactivity of fuel molecules such as C-H, C-C, C = C, and C-O. Changes in the physical properties of the fuel, the geometry of the carbon chain, and molecular mass ease the absorption of heat by the fuel droplet, thereby increasing fuel ignition performances.

Abstract

This study aims to reveal the performance and exhaust emissions of a spark ignition (SI) engine fueled by a gasoline-bioethanol mixture. The main performance characteristics of the SI engine tested are torque, power output; thermal efficiency, brake specific fuel consumption, and brake mean effective pressure. Meanwhile, the exhaust emissions seen are carbon monoxide and hydrocarbons. The test is carried out by comparing the performance of the SI engine under standard conditions without modification with gasoline fuel, with the SI engine with modification with 85% bioethanol fuel. The mass flow of fuel is regulated by modifying the carburetor choke at 3/4 and 7/8. The results show that although slightly lower than gasoline, in general, it can be seen that bioethanol can improve SI engine performance and produce environmentally friendly exhaust emissions.

Abstract

Household sector as the second largest energy user after the industrial sector, thereality of what happened in Papua subsidized price of kerosene has reached Rp 6,000 - Rp10,000/liter due to government policy. Wood processing industry produces 40% of woodwaste which cause problems that impact on the environment. Need to use it into valueadded products, one of them as an alternative energy source to help alleviate the localeconomy.The method used in this study is an experimental analysis, by comparing the stovewithout the firewall and the firewall, and the temperature distribution was taken usinginfrared thermograph, and the other to obtain temperature data used infrared thermometer.The results of this study showed the exit temperature (out) with firewalls tend to behigher (591,1°C) compared with no firewall (583°C), because the firewall to isolate heat sothat the heat of combustion are all routed through the firewall to the outside of the pan isreinforced with color degradation results thermograph. But without the firewall and thetemperature rising back tends to decline because of the longer sawdust burning to ashes sothat has not been burned sawdust automatically drops down so that the distance of the potwith the heat source and the heat of combustion is much spread do not like using a firewall

Abstract

Upaya manusia untuk menciptakan kondisi yang lebih sejuk dilakukan dengan sistem Air Conditioning (AC), salah satu AC yang digunakan pada sistem transportasi yaitu AC mobil. Coefficient of Performance (COP) merupakan perbandingan efek refrigerasi dengan kerja kompresor. Efek refrigerasi dikalkulasikan dari besarnya enthalpy refrigerant yang masuk kompresor atau enthalpy yang keluar dari evaporator dibagi dengan enthalpy refrigerant yang masuk evaporator atau enthalpy sesudah katup ekspansi. Secara lebih jelas bahwa Coefficient of Performance (COP) adalah perbandingan efektifitas pendinginan evaporator dengan kerja yang diberikan kompresor. Penelitian ini bertujuan untuk menghitung dan membandingkan Coefficient of Performance Refrigerant jenis R-134A, HFC-134 dan MC-134. Metode yang digunakan adalah secara eksperimental dengan mengkaji nilai efisiensi dari AC mobil toyota avanza 1.3cc dengan variasi Freon R 134A, HFC 134A dan MC 134. Hasil penelitian menunjukkan nilai COP aktual dan COPideal yang terbaik menggunakan MC-134 karena nilai konduktivitas termal MC-134 paling tinggi sehingga kalor yang diserap evaporator lebih tinggi yang membuat nilai dari COP yang didapat lebih tinggi. Untuk efisiensi kompresor yang terbaik menggunakan HFC-134 karena nilai viskositas dan densitas dari HFC-134 lebih tinggi yang membuat kerja kompresor lebih ringan sehingga membuat efisiensi kompresor lebih tinggi

Abstract

The mechanized ability to specify the way surface type is a piece of key enlightenment for autonomous transportation machine navigation like wheelchairs and smart cars. In the present work, the extracted features from the object are getting based on structure and surface evidence using Gray Level Co-occurrence Matrix (GLCM). Furthermore, K-Nearest Neighbor (K-NN) Classifier was built to classify the road surface image into three classes, asphalt, gravel, and pavement. A comparison of KNN and Naïve Bayes (NB) was used in present study. We have constructed a road image dataset of 450 samples from real-world road images in the asphalt, gravel, and pavement. Experiment result that the classification accuracy using the K-NN classifier is 78%, which is better as compared to Naïve Bayes classifier which has a classification accuracy of 72%. The paving class has the smallest accuracy in both classifier methods. The two classifiers have nearly the same computing time, 3.459 seconds for the KNN Classifier and 3.464 seconds for the Naive Bayes Classifier.

Abstract

Experimental research has been conducted on the effect of ignition timings on the characteristics and performance of gasohol engines such as power, torque, specific fuel consumption, and thermal efficiency. The fuel used in this research is pure gasoline and a mixture of 50% bioethanol (BE50). The results show that the ignition timing that gives the maximum effect occurs at the top and bottom dead points of 9 degrees for gasoline and 12 degrees for BE50 fuel. Furthermore, the maximum power is obtained at 6,500 rpm, and at an ignition time of 12 degrees BTDC the maximum power generated is 4.63 hp, while for an ignition time of 9 degrees BTDC the power generated is 3.38 hp which occurs at 6500 rpm. These results indicate that there is an increase in power of 6.4%. Moreover, the results also show that for optimal gasoline conditions, the amount of energy consumed at an engine speed of 7000 rpm is around 15705.78 kcal/hour, and for BE-50 it is around 12582.03 kcal/hour, where there is a reduction of about 25.44 %. However, in general, it can be seen that during optimal ignition, there is a saving in fuel consumption in the gasoline-BE50 mixture, while at the same time producing a fairly large thermal efficiency. These results indicate that BE50 has the potential to be used as an alternative fuel in small gasoline engines.
