2019-28-2582
Reliability states the degree to which the result of a measurement, calculation, or specification can be depended on to be accurate. And, tests according to GMW specifications represents a minimum of 15 years of vehicle life time with defined Reliability and Confidence level. In this work, actual number of thermal cycles for Thermal Fatigue tests (Thermal Shock and Power Temperature Cycle) are calculated for Copper Wire whose Coffin Manson exponent is 5. Overstressing the PEPS Antenna under thermal fatigue requirement (defined number of thermal cycles based on Reliability and Confidence requirements) will lead to broken Copper wire which will result in component’s functional failure and thus impossible to continue reliability testing. The objective of this paper is to determine thermal fatigue requirements for Antenna’s Copper wire whose Coffin Manson exponent is 5.

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.

A Technical Review on Performance and Emissions of Compressed Natural Gas – Diesel Dual Fuel Engine

2019-11-21
2019-28-2390
In view of the depletion of energy and environmental pollution, dual fuel technology has caught the attention of researchers as a viable technology keeping in mind the increased availability of fuels like Compressed Natural Gas (CNG). It is an ecologically friendly technology due to lower PM and smoke emissions and retains the efficiency of diesel combustion. Generally, dual fuel technology has been prevalent for large engines like marine, locomotive and stationary engines. However, its use for automotive engines has been limited in the past due to constraints of the limited supply of alternative fuels. CNG is a practical fuel under dual-fuel mode operation, with varying degree of success. The induction method prevents a premixed natural gas-air mixture, minimizes the volumetric efficiency and results in a loss of power at higher speeds.

Modeling for collective effect of Muffler geometric modifications and blended microalgae fuel use on exhaust performance of a four-stroke diesel engine: A Computational Fluid Dynamics Approach

2019-11-21
2019-28-2377
Engine performance significantly depends on the effective exhaust of the combustion gases from the muffler. With stricter BSVI norms more efficient measures has to be adopted to reduce the levels of exhaust emissions from the exhaust to the atmosphere. Muffler along with reducing the engine noise, is intended to control the back pressure as well. Back pressure change has significant effect on muffler temperature distribution which affects the NOx emission from the exhaust. Many research communications have been made to reduce the exhaust emissions like HC, CO and CO2 from the exhaust by using different generation biofuels as alternate fuel, yet they have confronted challenges in controlling the NOx content from exhaust. This work presents the combined effect of Muffler geometry modifications and blended microalgal fuel on exhaust performance with an aim to reduce NOx emission from the exhaust of a four-stroke engine.

Development of Dedicated Lubricant for Hydrogen Fueled Spark Ignition Engine

2019-11-21
2019-28-2511
Hydrogen has low ignition energy ensures easy ignition of the ultra-lean mixture of H2+air also. The flame speed of hydrogen is about five times higher than methane and gasoline which allows hydrogen fuelled IC engines to have relatively reduced cyclic variations than that of with methane and gasoline. High flame speed also helps to make the combustion closer to constant volume which enhances the thermal efficiency of hydrogen fuelled IC engine. High octane number of hydrogen makes it suitable for its application in Spark ignition (SI) engines. Since the hydrogen combustion in spark ignition engine generates water which can interfere with the lubricant performance, different lubricant is to be developed for this purpose. In this background, the present work is aimed at the development of dedicated lubricant for hydrogen fuelled SI engine. This paper presents the various parameters required for evaluating different lubricants for hydrogen fuelled genset.

2019-28-2379
A major challenge for combustion development is to optimize the engine for improved fuel economy, reduce greenhouse gases. Stringent CAFÉ and emission norms require the customer to pay higher capital on vehicles. To offset the cost of ownership- cheaper and alternative energy sources are being explored. Ethanol blend with regular Gasoline and CNG are such alternative fuels. The study was carried on turbo-charged gasoline direct injection engine. The effect of ethanol on engine and vehicle performance is estimated and simulated numerically. The work is split into three stages: first the base 1D engine performance model was calibrated to match the experimental data. In parallel, vehicle level Simulink model was built and calibrated to match the NEDC cycle performance. Second, the thermal efficiency of the ethanol blend is calculated as a linear function of theoretical Otto cycle efficiency.
