Vechiles emit large amounts of emissions in towns of developing countries. This study is descriptive research. Analyzer gas as well as opacity were used to collect the necessary data. The objects of the study were motorized diesel engine as well as gasoline engine of various brands that operated around Sleman, a regency in Special Region of Yogyakarta, Indonesia. Those vehicles produce three main exhaust gases: CO, HC, and PM. The largest CO emissions, with figure reaching 6.92%, come from gasoline-powered Suzuki units released in 1993. Daihatshu units released in 1993 emit the largest HC emissions up to 538 ppm. Meanwhile, diesel-powered vehicles that produce the most Particulate Matter come from Mitsubishi that were released in 2008, with figure reaching 64.55%.HSU. The analysis of exhaust gas emissions will encourage vehicle owners who haven't yet passed their emission test to do regular maintenance as well as put the right type of fuel into their vehicles.

“…A real combustion process also produces pollutants such as carbon monoxide (CO), unburned hydrocarbons (HC), nitrogen oxides (NO X ), and particulate matter. CO 2 is not considered a pollutant because it is not harmful to health, but it is harmful to the environment (Bagány, 2011;Eckert and Rakowski, 2012;Kalmár and Stukovszky, 1998;Vas, 2005). These statements are valid as far as conventional transportation fuels are concerned.…”

To date, huge amounts of money have been invested in the development of internal combustion engines to reach the current level of technology. High specific power and good thermal efficiency have been achieved, thanks to which, internal combustion engines are now widely used. However, the driving force behind the developments is no longer the high performance, but the compliance with strict emission standards. Future emissions regulation, namely Euro 7, will be challenging for engine and vehicle manufacturers. One possible technical solution may be to use a stoichiometric air-fuel mixture on the entire engine map to meet the requirements of the Euro 7 emission standard. This article analyzes the change in Euro regulations in the light of Euro 7, as well as the theoretical background of the λ = 1 operation. Several technical possibilities to achieve the stoichiometric ratio, such as e.g. water injection or variable compression ratio are presented.

Abstract-A thrust allocation method with a functionality to assist power management systems by using the hull of the ship as a store of potential energy in the field of environmental forces has been recently proposed and demonstrated to work in simulation. This functionality allows the thrust allocation algorithm to decrease the power consumption in the thrusters when a sharp increase in power consumption is demanded elsewhere on the ship. This way, the high-frequency part of the load variations on the power plant can be reduced, at the expense of minor (typically less than 1 meter) variations in the position of the vessel. The advantages from reduced variations in load include reduced wear-and-tear of the power plant, more stable frequency on the electric grid, reduced risk of blackout due to underfrequency, and more reliable synchronization when connecting additional generators or connecting bus segments. In the present work, this functionality is improved further by continuously monitoring the environmental forces and modifying the setpoint of the dynamic positioning algorithm to place the vessel a short distance (e.g. 20 cm) in the direction of steepest increase of the environmental force potential, thus maximizing the available potential energy. The increased potential energy creates additional capacity for assisting the power plant, which is shown in simulation to be significant.
