Exhaust Gas Emissions

The main factor of air pollution in Indonesia is motorized vehicles. Motorized vehicles operating on the road will produce exhaust gas emissions which result in air pollution. In overcoming exhaust gas emissions in vehicles, the Ministry of Transportation conducts training for exhaust emission inspection, and conducts training at one of the technical implementation units, namely the Indonesian Land Transportation Polytechnic (PTDI) STTD. The purpose of this study was to conduct a needs analysis to develop a hyper content learning module for training on exhaust emission examinations, using the R&D (research and Development) method using the Derek Rowntree model. The hyper content module is a module that combines hypertext, hyperlinks, and hypermedia, and the media used in the form of video, QR code, YouTube, and cloud computing. With the development of the hyper content module, it is possible to improve the understanding and learning outcomes of training participants in studying exhaust emissions from vehicles when compared to conventional learning.

AbstrakJumlah kendaraan bermotor yang meningkat menyebabkan peningkatan konsumsi bahan bakar dan pencemaran udara. Solusinya dengan memakai campuran bioethanol pada bahan bakar pertalite. Penambahan bioethanol dapat meningkatkan angka oktan sehingga membutuhkan beberapa perubahan pada mesin. Salah satunya dengan memajukan timing ignition. Metode yang digunakan adalah dengan memajukan timing igniton sebesar 21° BTDC, dan 30° BTDC dari kondisi standar yaitu 12° BTDC. Pengujian dilakukan dengan dynotest untuk mengetahui daya dan torsi. Pengujian emisi gas buang menggunakan alat gas analyzer. Berdasarkan hasil pengujian, penambahan bioethanol dapat meningkatkan daya, torsi, serta dapat menurunkan emisi gas buang. Daya tertinggi dicapai oleh variasi timing ignition 30° BTDC dengan E10 yaitu sebesar 6,7 Hp pada putaran mesin 6750 rpm. Torsi tertinggi dicapai oleh variasi timing ignition 30° BTDC dengan E10 sebesar 9 Nm pada putaran mesin 4000 rpm. Emisi gas buang, konsentrasi CO rata-rata terbaik dicapai oleh variasi timing ignition 30° BTDC dengan E10 sebesar 4%. Konsentrasi HC terendah pada variasi timing ignition 30° BTDC dengan E10 sebesar 74 ppm. Nilai rata-rata konsentrasi CO2 tertinggi pada timing ignition 30° BTDC dengan E10 sebesar 13,6%. Konsentrasi O2 terendah pada variasi timing igniton 30° BTDC dengan E10 sebesar 3% pada putaran mesin 7000 rpm.Kata Kunci: timing ignition, daya, torsi, emisi gas buang  AbstractThe increasing number of motorized vehicles has led to increased fuel consumption and air pollution. The solution is to use a bioethanol mixture on pertalite fuel. The addition of bioethanol can increase octane numbers so that it requires some changes to the engine. One of them is by advancing timing ignition. The method used is to advance the timing igniton at 21 ° BTDC, and 30 ° BTDC from the standard condition of 12 ° BTDC. Testing is done with dynotest to determine power and torque. Exhaust gas testing uses a gas analyzer. Based on the results of testing, the addition of bioethanol can increase power, torque, and can reduce exhaust emissions. The highest power is achieved by variations of the timing ignition 30 ° BTDC with E10 which is 6.7 hp at 6750 rpm. The highest torque is achieved by variations of the timing ignition 30 ° BTDC with E10 of 9 Nm at 4000 rpm engine speed. Exhaust gas emissions, the best average CO concentration is achieved by variations of the timing ignition 30 ° BTDC with E10 by 4%. The lowest HC concentration in the variation of timing ignition 30 ° BTDC with E10 is 74 ppm. The highest average CO2 concentration at the timing ignition 30 ° BTDC with E10 is 13.6%. The lowest O2 concentration in timing variations igniton 30 ° BTDC with E10 at 3% at 7000 rpm engine speed

Exhaust Gas Emissions

Maritime transportation is a major source of climate change and air pollution. Shipping emissions cause severe impacts on health and environment. These effects of emissions are emerged especially in territorial waters, inland seas, canals, straits, bays, and port regions. In this paper, exhaust gas emissions from ships in Izmir Port, which is one of the main ports in Turkey, are calculated by the ship activity-based methodology. Total emissions from ships in the port is estimated as 1923 ton y−1for , 1405 ton y−1for SO2, 82753 ton y−1for CO2, ton y−1for HC, and 165 ton y−1for PM in the year 2007. These emissions are classified regarding operation modes and types of ships. The results are compared with the other studies including amounts of exhaust pollutants generated by ships. According to the findings, it is clear that the ships calling the Izmir Port are important air polluting causes of the Izmir city and its surroundings.

Determine Effect

The perfect combustion process can occur if the high compression pressure, proper ignition time, and suitable fuel air mixture. Suitable fuel air mixture can be obtained by heating the fuel to reduce its viscosity so the mixture is more homogeneous. Fuel heating can be done in various ways, such as by utilizing the heat of radiator water coming out of the engine. The purpose of the study is determine effect of the fuel heating to exhaust emission of gasoline engine 1800cc. The study uses experimental with the variable used pertamax with temperature 40°, 50°, 60°, and 70°. The dependent variable in the study is exhaust emission of gasoline engine. The results of the study indicate that fuel heating affects exhaust emissions. Temperature that affects the exhaust gas emissions at 60o C with the use of pertamax fuel.

Exhaust Gas Emissions

A swirl stabilized MGT combustor (Turbec T100) was operated with natural gas and was experimentally characterized in two test rigs, a pressurized and optically accessible MGT test rig and an atmospheric combustor test rig. For the detailed characterization of the combustion processes, planar OH-PLIF and simultaneous 3D-stereo PIV measurements were performed in the atmospheric combustor test rig. Flow fields, reaction zones and exhaust gas emissions are reported for a range of pressure scaled MGT load points. Parameter studies on combustor inlet conditions (e.g. air preheating temperature, air and fuel mass flow rates and fuel split) were conducted in the atmospheric combustor test rig. From the parameters studies the fuel split between the pilot and the main stage and the air preheating temperature were found to have the biggest impact on the flame shape, flame stabilization and exhaust gas emissions. The measurements of the ATM test rig are compared with measurements of the pressurized MGT test rig with and without an optically accessible combustion chamber. Opened and closed conical flame and flow pattern were found in both test rigs. Reasons for the two flame and flow pattern are supposed to be the interaction of pilot stage combustion and flow field and the interaction of the dilution air with the combustion and the flow field. The results are discussed and compared with repect to a transferability of combustion characteristics from the ATM test rig to the MGT test rigs.
