“…Before the diesel engine start off, the heating element within the GP must be activated during about 10 to 20 s depending on the volume of combustion chambers. At the end of this time, the tip surface of the GP reaches a temperature between about 800 to 1000 °C allowing a comfortable engine start [12]. By using the GP, the smoke released from the engine during the start off is reduced from about 49 % to 60% [13][14].…”

In Diesel Engines, the heat energy obtained from the glow plug increases the engine's ability to start up in cold climatic conditions and significantly reduces emissions of harmful gases leaving the exhaust. In cold climatic conditions, before the start off of diesel vehicles it is necessary to wait for about 10 s the cylinder block heating. This period negatively affects driving comfort. In this study, the mathematical results of the processes to optimize the time required for the glow plug to reach the required temperature have been experimentally proven. A test apparatus was developed to confirm experimentally the theoretical results. Thanks to these improvements concerning the manufacture of the glow plug, the time period to reach 850 ° C has been reduced by approximately 5 s. The proposed design is in accordance with the glow plug present in the market. Currently the whole glow plug must be changed at the end of lifetime, with our improvement only the inner tube resistance can be easily changed involving a cost reduction by about 60%.

“…According to the scientific results, the amount of CO 2 in the atmosphere has increased remarkably with the growing potential of the industrial productions. The increased amount of CO 2 emission into the atmosphere could lead to global warming which is one of the most challenging environmental problems of our time mentioned by Rose et al, Kaygusuz, and Özcan et al [1][2][3].…”

“…Global warming and its resulting climate changing effect are directly related with the increasing of energy consumption. About 1 kg CO2 which makes 0.546 m 3 volumes at room temperature and standard pressure (25 °C, 1 atm) is released to the atmosphere for each 1 kWh of energy generation. Similarly, after burning process of the combustion gases such as methane (CH 4 ) or propane (C 3 H 8 ), forms about 0.275 m 3 of CO 2 investigated by Jacobson et al [4].…”

This paper introduces a new method related to the joining of the metal pieces using cylindrical welding technique by determining double seam profile tracking. With the help of this method, solid and stabile welding quality is achieved on the applied materials. For this aim, a welding oscillator is implemented. The cylindrical welding operation is carried out properly on the applied metal pieces with the aid of two laser sensors, which find and eliminate eventual joining faults. Firstly, the position of the welding region is determined using the first laser sensor. After the welding process is done, a second laser sensor is used to check for the detection and elimination of the possible welding faults, so that a high quality welds can be performed. With the suggested cylindrical welding technique, only one special welding is required that makes the whole process more environment and budget friendly. Furthermore, the required energy and time for the welding operation are reduced significantly compared to the conventional manual welding. Moreover, consumption of hazardous gases, which are needed for protective shielding during the welding process such as carbon dioxide (CO2), electric energy and electrode mass, were reduced greatly due to the elimination of the unnecessary welding operations.

Glow plug is a simple method to improve cold start for diesel engines, especially for cold conditions and first starting. In cold or iced weather conditions, diesel engines cannot reach the ignition temperature just compressing the air. Thus, heated air must be added to combustion chamber before the compressing via external device such as glow plug. Glow plug helps engine regulate the first starting and leads to obtain low emission during the cold starting or up to warm up the engine due to its controllability. Although glow plug installing is easy way to improve heat air obtaining, glow plugs have some limitations. Major problem, generated heat inside the glow plug starts from inside to outside. Thus, it takes time to obtain heated air. During the extremely cold weather conditions, one cycle not enough for heating. So, temperature of air is another major factor reducing the glow plug affect. On the contrary, induction heating is fast and efficient method and could be acceptable new generation method compared the resistive heating. Induction heating is based on hysteresis losses at high frequency switching. Induction heating has strong affect on iron based materials which has large hysteresis are. Our method is based on induction heating using 368 kHz switching frequency to improve heating capability. In addition to resistive heating, induction heating increases the heat volume. Moreover, induction heating effects the cover of the glow plug, thus improve method has no destructive affect on the core of glow plug because the surface heating.
