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.

SNCR (Selective Non Catalytic Reduction) system is proposed, with 40% methylamine aqueous solution as reducing agent to reduce NOx in diesel exhaust gas. The effect of injection position and volume on the reduction efficiency through the test bench is systematically researched. A three-dimensional model of a full-sized diesel SNCR system generated by CFD software FIRE is used to investigate the reduction efficiency under different temperatures. The simulated results have a good agreement with the test results, and it can be used to optimize SNCR system. The results can indicate the practical application of this technology.

Through the analysis of the sealing mechanism of the oil seals in exhaust gas turbo supercharger and the comparative test of different oil seals with the pressure change in the oil-return chamber, a seal that uses a caulking ring with reverse threads is designed, and an optimum combination of oil seal is selected. The combination of caulking ring and the oil-return thread structure has better complementary action on oil sealing, because for the seal with oil-return reverse thread there is better dynamic and static seal effect on ring seal and has good sealing performance and high reliability at high speed. The test results of screening selection of combination seals show that different combinations of caulking ring and the oil-return threads have great influence on the pressure of the oil-return chamber. The combination of caulking ring outside and oil-return threads inside is recommended to be used. In addition, the smooth return of the oil can be ensured as far as possible by increasing the supercharger oil-return chamber volume. The improved structure of the oil seal has effectively enhanced the reliability of the whole unit of the exhaust gas turbo supercharger.

A field test was conducted on a three splitter diffuser and a vaneless diffuser (no splitters) to determine, the pressure recovery coefficient, effects on engine performance, exhaust collector temperature distribution, and exhaust gas noise. This paper presents the cause of the mechanical failure of the three splitter diffuser, basic diffuser design, field test instrumentation, and the test results. The test results found the vaneless diffuser had a higher pressure recovery, created a lower back pressure, and did not raise the exhaust gas temperature (EGT) nor fuel consumption of the engine, as compared to the three splitter diffuser.

Global warming and climate change are the motives to find a solution for emission reduction of diesel engines. Bioethanol is renewable fuel which can be used in diesel engine as a part of biodiesel-diesel blends. The effect of bioethanol on the emission performance of diesel engine for rapeseed biodiesel-diesel blends as a function of engine load is evaluated in this paper. KDE 6500E diesel generator is used for this purpose. Carbon monoxide (CO), unburned hydrocarbons (HC), oxygen (O2) and carbon dioxide (CO2) emissions are recorded with the help of VLT-458 exhaust gas analyzer. Blends with higher concentrations of bioethanol have shown lower CO emissions while HC emissions increase with the increase in bioethanol concentration in the blends. CO2 emissions are recorded more at higher loads for all types of biodiesel and bioethanol concentrations than that of diesel fuel.

This paper presents a methodology developed to measure exhaust gas emissions during operation of a miniature turbojet engine, using a laboratory test rig. The rig has been built for research and development works aimed at modelling and investigating processes and phenomena occurring in jet engines. The miniature jet engines, similarly to full–scale ones used commonly in air transport, are characterized by variable exhaust gas emissions, depending on engine operating parameters. For this reason, an attempt has been made to determine the characteristic features of miniature engine operation modes and to define the variability of operation parameters and exhaust gas emissions as a function of time. According to the authors, the preliminary tests allowed for defining specific profile of engine test, which enables proper measurement regarding exhaust gas emissions using the miniature jet engine. The paper also presents test results for Jet A-1 fuel, according to the used methodology.
