Acceleration Test

Atmospheric contains a variety of gases such as 78% nitrogen, 21% oxygen and 1% other gases.This causes incomplete combustion. Because the main composition of the combustion process is fueland oxygen. The use of zeolite physically activated by microwave which can increase the quality ofcombustion air. Zeolite is a type of rock that is capable of absorbing (capturing) molecularparticles or angstroms such as water vapor and nitrogen in the air. So that it will produce a richoxygen in the air when entering the combustion chamber. The performance of a 4-stroke motorcycleengine is good if there is a decrease in fuel consumption, it can increase the acceleration, andreduce exhaust emissions containing CO and UHC. To find out the effect of the zeolite filters onengine performance, an acceleration test of 0–80 km / h is performed. Zeolite is activated using amicrowave with 80% power, activation time is 3, 6, and 9 minutes, with gap of 75%. Then zeolitewas activated with 80%, 60%, and 40% power of microwave using 50%, 75%, and 100% gap(varying the gap arrangement of pellets). When the activation time of the filter is 3 minutes, it takes12.54 seconds to conduct, 6.53% faster, the a 6 minutes activation takes 12.58 seconds and 6.19%faster. The greater the activation power, the better acceleration. In the 80% acceleration test, 50%gap can increase the acceleration by a percentage of 6.16%. Meanwhile, the gap of 75% and 100%it can increase the acceleration by 5.64% and 3.86%.Keywords: Zeolite, physical activation, using microwave, increase acceleration

External Combustion

The Stirling engine is an external combustion where the fuel combustion process takes place outside the cylinder, at the combustion chamber or burner. Stirling engine offers flexibility of fuel used for the power generation hence is a potential substitute to fossil fuelled internal combustion engine and contribute toward more sustainable power generation. In this study a burner for Gamma V2-6 Stirling engine is designed and developed for a biogas-fuelled power generation system. The heat used to power the Stirling engine is obtained from combustion of biogas at the burner. The system has 5 kW capacity fuelled by 165 kg/day solid waste (biowaste) from local farm. The bio-digester needed is 20 m3. The combustion temperature of the burner is in the range of 600 to 1000°C. The required fuel input is 60,000BTU/hr or equivalent to 17 kW. The system requires constant heat from the combustion chamber hence a specific burner is designed to fulfil the purpose and accommodate biogas composition and optimum heat transfer to the engine. The burner is able to provide for simultaneous air preheater for lower fuel consumption leading to 37% lower fuel consumption.

The use of hydro-crack systems in combustion motors in addition to functioning to improve exhaust emissions and improve engine performance through the combustion process. Perfect combustion can be adjusted during the combustion process. The purpose of the study was to determine the select magnitude of power increase, decrease fuel consumption and increase the average effective pressure and rotation of the use of 92 octane fuel without HCS. The method of testing engine performance in obtaining data is constant speed (v boarding) based on ISO 1585. Subsequent data signifies presented in a graphical form which is then calculated by statistics. Power increased 2.83hP and bmep 43.19kPa at 4000rpm, sfc dropped 0.0358kg / hP. Hours at 1000rpm and rose by 43.19kPa, when using 92 octane fuel against the standard. When using octane 95 with HCS the power rises 7.95hP at 4000rpm, buys 28.42 kPa when 4500 and sfc drop 0.0537kg / hp.

Flame Development

Diesel engines generate undesirable exhaust emissions during combustion process and identified as major source pollution in the worldwide ecosystem. To reduce emissions, the improvements throughout the premixing of fuel and air have been considered especially at early stage of ignition process. Purpose of this study is to clarify the effects of swirl velocity on flow fuel-air premixing mechanism and burning process in diesel combustion that strongly affects the exhaust emissions. The effects of physical factors on mixture formation and combustion process to improve exhaust emissions are discussed in detail. This study investigated diesel combustion fundamentally using a rapid compression machine (RCM) together with the schlieren photography and direct photography methods. RCM was used to simulate actual phenomenon inside the combustion chamber with changing design parameter such as swirl velocity, injection strategies and variable nozzle concept. The detail behavior of mixture formation during ignition delay period was investigated using the schlieren photography system with a high speed digital video camera. This method can capture spray evaporation, spray interference and mixture formation clearly with real images. Ignition process and flame development were investigated by direct photography method using a light sensitive high-speed color digital video camera. Moreover, the mechanism and behavior of mixture formation were analyzed by newly developed image analysis technique. Under high swirl condition, the ignition delay is extended, the higher heat losses and unutilized high-density oxygen associated with slower initial heat recovery begins might be the explanation for the longer combustion duration, reductions of pick heat release and promote combustion and soot oxidation. The real images of mixture formation and flame development reveal that the spray tip penetration is bended by the high swirl motion, fuel is mainly distributed at the center of combustion chamber, resulting that flame is only formed at the center region of the combustion chamber. It is necessary for high swirl condition to improve fuel-air premixing.

The technological development of the automotive sector is increasing, every year there is an increase in the production of motor vehicles in Indonesia. The increase in motorized vehicles will certainly have an impact on the use of fuel oil which is also increasing. Though fuel oil is a non-renewable fossil fuel, so that continuous use can lead to scarcity of fossil fuels someday. In addition to causing scarcity of fossil fuels, the increasing number of vehicles will also cause the surrounding environment to be increasingly polluted by the exhaust emissions from the combustion process of the motorized vehicles. Various alternatives are used as a mixture of fuels to reduce fuel consumption and vehicle exhaust emissions, such as ethanol, hydrogen, butanol, biodiesel, methanol etc. The purpose of this literacy study was to determine the effect of using ethanol on fuel consumption and its economic value. Based on the results of a study of literacy is known that the addition of ethanol does reduce the level of fuel consumption, However, if viewed from an economic perspective, the addition of ethanol has actually caused the purchase price of fuel to increase, this will certainly hinder the growth of the desire to use ethanol as an alternative source of fuel substitute by the people of Indonesia.
