Exhaust Gas Emissions

This paper presents the measurement process of the emissions from marine diesel engines. The emission measurement was carried out by the certified TESTO 350 Maritime exhaust gas analyzer on the Juraj Dalmatinac ferry Caterpillar C32 engines. The gas analyzer records the concentrations of nitrogen oxides (NOx), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and sulfur dioxide (SO2). TESTO 350 emission sampling probe was set at the end of the exhaust pipe. A combustion emission measurement was performed during a Split – Supetar (Brač) trip and backwards with the total duration of 110 min. The emissions are estimated for two trip phases: “maneuvering” and “at sea”.

Exhaust Gas Emissions

A research has been done to observe the effect of varying the retainer angle on the performance of oil burner in terms of exhaust gas emissions and temperatures. Retainer was a flame stabilizer used to stabilize the flame, improve mixing between air and fuel and affect the formation of emissions such as carbon monoxide (CO), carbon dioxide (CO2), oxides of nitrogen (NOX), and sulfur dioxide (SO2). These emissions can cause harm to the world ecosystem. One of the methods to reduce emissions was by varying the retainer's blade angle to certain angle that complete the combustion with high efficiencies and less emissions. In this research, an oil burner with four different retainer angles has been investigated using a combustor of one meter length. Tests were conducted using diesel as feedstock. Four different retainer angles used are 15°, 30° (baseline), 45°, and 60° with swirl number 0.2016, 0.4344, 0.7524, and 1.3032. From the experiment, data shown that swirling flow affect the formation of recirculation zone thus provides the aerodynamics blockage to stabilize the flame and emissions reduced due to varying the retainer angles and the best retainer angle was achieved by consider the exhaust gas emission reduction.

The high population in Indonesia has an impact on increasing the mobility of the population in work and activities, which is followed by the increased transportation facilities needed by the community. One of the negative effects of the increasing number of vehicles is the danger of exhaust emissions. One way to minimize the danger of exhaust gases is to regulate the mixture of air and fuel on the gasoline engine. In Yamaha injection motors there is a CO setting technology, this technology will have an impact on fuel use. The standard CO on a Yamaha motorbike is 0 and can be added or reduced (±) until it reaches 30. Increasing CO one strip will cause the fuel sprayed by the injector to be reduced by 0.05 cc. Examination of exhaust gas emissions is carried out using the Qrotect 401 Engine Gas Analyzer which is capable of measuring CO2, O2, CO, HC and Lamda. Based on the test results show that the lowest exhaust emissions are produced by the vehicle at 2500 rpm and in CO-30 mode settings, namely CO gas emissions of 0.49%. So we can conclude that the lowest exhaust gas emissions are produced by the vehicle at rpm 2500 with CO-30 settings. In addition to co mode settings, variations in engine rpm also affect exhaust emissions. In different modes but with different rpm the results will also be different. In the CO 10 mode setting with rpm 1400 CO gas emission is produced at 2.102 while at 2500 rpm is produced 0.821. So at rpm 2500 produced exhaust emissions lower than rpm 1400. There is a significant effect between CO mode settings and engine rpm on motorcycle exhaust emissions.

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.

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.

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

A generic computer model for systematic investigations of container ship designs is described in this paper. The primary statistical data on container ships used for the model development are also presented. The model can be used to calculate exhaust gas emissions from container ships, including emissions of carbon dioxide (CO2). A calculation procedure to estimate the newly designated Energy Efficiency Design Index (EEDI), which is under development at the International Maritime Organization (IMO), is included in the model. Different ship design parameters have been varied to see the influence of these parameters on the EEDI. It is found possible to reduce EEDI by roughly 20 % without reducing ship speed, but only by changing some of the design parameters, such as reducing the sea margin by using a derated main engine, increasing the length of the ship by 5 %, and reducing steel weight by 3 % via steel weight optimization.
