Along with the development of internal combustion engines, camshafts have also been developed to optimize engine performance. In all types of internal combustion engines, the crankshaft is connected to the camshaft via a toothed belt, chain or pinion. When the crankshaft turns, the camshaft spins and opens and closes the intake and exhaust valve respectively. However, in this non-camshaft engine technology, each intake and exhaust valve will be integrated with an electronically controlled hydraulic pump unit. This system provides a unique ability to independently control intake and exhaust valves. For any engine load, load and discharge times can be programmed independently. The decision system is based on driving conditions, used to maximize performance or minimize fuel consumption and emissions. This allows a greater degree of control over the engine which in turn provides significant performance benefits. This article presents reviews of camshaftless technology developed by VALEO. It is a system that uses solenoid valves to open and close the valve. The solenoid valve will be mounted right on top of the valve inside the engine. The author can see that the technology using this electronic control valve will help reduce the fuel consumption of the engine.

Urban areas are constantly developing and rapidly, especially in recent times. According to the United Nations, in 1950 the global urban population accounted for only 29% of the world's population; this figure was 50% in 2009 and will be 60% in 2030 with about 5 billion people. In Vietnam, urban population is projected to account for 38% of the country's population by 2015, 45% of the country's population in 2020 and 50% of the national population by 2025 with about 25 million. In the process of urbanization with growth and development, cities often face significant challenges. These are: 1) Unbalanced development, over-focus on large cities makes the development gap between urban and rural areas more and more increasing; 2) Unsustainable development, rapid technical and social infrastructure systems degrading rapidly, especially housing and environmental sanitation; 3) The administrative management capacity of urban governments must often chase the rapid growth of urban areas; 4) Poverty, crime and unemployment often occur in rapidly growing cities but lack solid economic and technical bases. In order to have an identity of sustainable urban development, development cannot be separated from preserving stability in which urban management is always a very important task.

“…The environmental issues related to fossil fuel are so hazardous that increasingly solutions for preserve our mother earth were paid serious attention by both developed and developing countries (Hoang et al 2021d) (Hoang & Pham 2019). The basic way to solve pollution from fossil fuel is to move away from them by replacing with clean fuels like biodiesel and renewable diesel, alternative resources such as wind, solar or wave energy, and geothermal (Hoang et al 2021b). Thereby, efficiency enhancement and emissions reductants are key standards for developing advanced and new energy technologies (Hoang & Le 2019) (Hoang et al 2021e).…”

Passive solar still is the simplest design for distilling seawater by harnessing solar energy. Although it is undeniable that solar still is a promising device to provide an additional freshwater source for global increasing water demand, low thermal efficiency along with daily distillate yield are its major disadvantages. A conventional solar still can produced 2 to 5 L/m2day. Various studies have been carried out to improve passive solar stills in terms of daily productivity, thermal efficiency, and economic effectiveness. Most of the researches that relate to the daily output improvement of passive solar still concentrates on enhancing evaporation or/and condensation processes. While the condensation process is influenced by wind velocity and characteristics of the condensed surface, the evaporation process is mainly affected by the temperature of basin water. Different parameters affect the brackish water temperature such as solar radiation, design parameters (for example water depth, insulators, basin liner absorptivity, reflectors, sun tracking system, etc). The inclined angle of the top cover is suggested to equal the latitude of the experimental place. Moreover, the decrease of water depth was obtained as a good operational parameter, however, the shallow water depth is required additional feed water for ensuring no dry spot existence. Reflectors and sun-tracking systems help solar still absorb as much solar intensity as possible. The internal reflector can enhance daily yield and efficiency of stepped solar still up to 75% and 56% respectively, whereas, passive solar still with the support of a sun-tracking system improved daily yield up to 22%. Despite large efforts to investigate the impact of the different parameters on passive solar distillation, the effect of the basin liner (including appropriate shapes and type of material), needs to be analyzed for improvement in practical utilization. The present work has reviewed the investigation of the solar still performance with various types of basin liner. The review of solar stills has been conducted critically with rectangular basin, fins basin, corrugated basin, wick type, steps shape, and cylindrical shape basin with variety of top cover shapes. The findings from this work conclude that the basin liner with a cylindrical shape had better performance in comparison with other metal types and provides higher freshwater output. Stepped type, inclined, fin absorber, and corrugated shapes had the efficient performance. Further exploration revealed that copper is the best-used material for the productivity of passive solar still.
