Combustion and Emissions for Engineers

2019-12-09
Public awareness regarding pollutants and their adverse health effects has created an urgent need for engineers to better understand the combustion process as well as the pollutants formed as by-products of that process. To effectively contribute to emission control strategies and design and develop emission control systems and components, a good understanding of the physical and mathematical principles of the combustion process is necessary. This seminar will bring issues related to combustion and emissions "down to earth," relying less on mathematical terms and more on physical explanations and analogies.

Vehicle weight reduction becomes important at the view point of fuel efficiency improvement and CO2 reduction in India also as well as developed countries. With this background, High tensile and Super high tensile steel application has become increasing. Similary, weight reduction of big plastic parts like bumper face is one of the most important items, so Honda has developed Thin-wall and light weight bumper face. In the development of light weight bumper, rigidity, impact strength and flowability which are main requirement are cotradictory property. It is necessary to develop new material to achieve this technical concern. Moreover, we verified part shape and thickness optimization to achieve part requirement. Established high property material and part manufacturing technology were applied for current CITY firstly, and it has been expanded to other models sequentially to contribute weight reduction for Honda vehicles.

A review on influence of different flushing methods on Material Removal Rate using EDM.

2019-11-21
2019-28-2543
Electrical release machining (EDM), is a material removal procedure whereby a coveted shape is acquired by utilizing electrical releases (sparks). Material is expelled from the work piece by a progression of quickly repeating current releases between cathode and anode, isolated by a dielectric fluid and subject to an electric voltage. At the point when the voltage between the two terminals is expanded, the power of the electric field in the volume between the anodes winds up more prominent than the quality of the dielectric (in any event in a few spots), which separates, enabling current to stream between the two cathodes. This wonder is the equivalent as the breakdown of a capacitor (condenser). Accordingly, material is expelled from the cathodes.

Keywords – Miniaturization, Low Profile (LP) Relays, Low Profile (LP) Fuses, Fuse box, Wiring Harness Research and/or Engineering Questions/Objective With the exponential advancement in technological features of automobile’s EE architecture, designing of power distribution unit becomes complex and challenging. Due to the increase in the number of features, the overall weight of power distribution unit increases and thereby affecting the overall system cost and fuel economy. The scope of this document is to scale down the weight and space of the power distribution unit without compromising with the current performance. Methodology Miniaturization involves replacing the mini fuses and J-case fuses with LP mini and LP J-case fuses respectively. The transition doesn’t involve any tooling modification and hence saves the tooling cost.

A high impetus from Government on road infrastructure development, is giving a fillip to passenger CV space. This has resulted in making the passenger CV segment lucrative enough, thereby pulling in many operators in the business. The quality of road has immensely improved over a decade, as a result of which the average speed and hence the quantum of distance covered by passenger buses has increased significantly. People are preferring to travel in buses over trains, owing to at par ticket cost, high availability, reduced travel time and also improved level of comfort. Aligned to the market need and the trend, OEM's are offering buses with capable powertrains to cater the need of speed, reduced trip time as well as a lot of attention is also being paid to tune in the comfort level for long hauls. A big chunk of passenger travel is catered by the bus operators especially during major festivals in India.

Research and/or Engineering Questions/Objective - This invention relates to introduction of GREEN LED LIGHT for safety, fuel saving, pollution control and motion indicator in automobiles. At present, every vehicle is provided with red light, orange light and white light at the rear end of the vehicle. Now, there is no such light which can tell about the motion of the vehicle, whether the vehicle's engine is using its power to move or going on in rolling condition. According to the present invention a GREEN LED LIGHT is introduced at the rear end f the vehicle. The green led light is on when the vehicle is using its engine's power to move. At present, when we drive behind the vehicle we continuously make assumption about the motion of the vehicle in front of us. This GREEN LED LIGHT will give exact information about the motion of the vehicle.

The need of Diesel as fuel has greatly pressurized the now scarcely available natural resources and is likely to become a luxury for the future generations. This paper aims at finding an alternate for diesel that can hopefully reduce the pressure on its existing demand. This paper presents a comparative study on use of different blends of Jatropha Oil (J) and Ethanol (E) as fuel in a diesel engine to observe its performance and emission characteristics. The findings are later compared with corresponding values of neat Diesel as fuel. Since Jatropha oil is more viscous and has polyunsaturated characteristics in its natural form, its ethyl ester was produced by transesterification process and later blended with Ethanol in different proportions like 90% J 10%E, 80J-20E, 70J-30E and 60J-40E.

Currently Automotive industry is looking for sustainable alternate of Conventional fuels. Bio diesel is an alternative fuel similar to conventional or ‘fossil’ diesel. It is produced from vegetable oil, animal fats, tallow and waste cooking oil. Bio diesel is one of the most promising fuel which can not only replace the conventional fuels but also environment friendly in terms of Greenhouse gases emission. Bio diesel can be produced from various sources and can be sustainable fuel for automotive vehicles. In this paper, efforts have been taken to convert existing Diesel engine into Bio diesel compliant engine. For making suitable for Biodiesel operation, modification in Engine Fuel system, filter and Sealing were carried out. Further Engine performance and emission testing were done and results were compared with performance and emission of same configuration Diesel engine.

This experimental study is to investigate the performance of treated waste engine oil and butanol as fuel to diesel engine operated under optimal engine operating parameters. This study was conducted in four stages: Treating the waste engine oil; Preparation of blends and testing the properties; Arriving at an optimal injection timing, nozzle opening pressure, compression ratio, and intake air temperature to suit the possible blend of treated waste engine oil and butanol; Testing the possible blend under optimal operating parameters under various load conditions. The properties test indicated that 35% of butanol can be blended with treated engine oil with respect to the essential properties for fueling diesel engine. To optimize the parameters L16 orthogonal array with the Taguchi method was used.

Downsizing is one of the crucial activities being performed by every automotive engineering organization. The main aim is to reduce – Weight, CO2 emissions and achieve cost benefit. All this is done without any compromise on performance requirement or rather with optimization of system performance. This paper evaluate one such optimization, where-in radiator assembly with two electric fan is targeted for downsizing for small commercial vehicle application. The present two fan radiator is redesigned with thinner core and use of single fan motor assembly. The performance of the heat exchanger is tested for similar conditions back to back on vehicle and optimized to get the balanced benefit in terms of weight, cooling performance and importantly cost. This all is done without any modification in vehicle interface components except electrical connector for fan. The side members and brackets design is also simplified to achieve maximum weight reduction.
