Designing On-Board Diagnostics for Light and Medium Duty Emissions Control Systems

2020-10-20
On-board diagnosis of engine and transmission systems has been mandated by government regulation for light and medium vehicles since the 1996 model year. The regulations specify many of the detailed features that on-board diagnostics must exhibit. In addition, the penalties for not meeting the requirements or providing in-field remedies can be very expensive. This course is designed to provide a fundamental understanding of how and why OBD systems function and the technical features that a diagnostic should have in order to ensure compliant and successful implementation.

Design Considerations for Secure Embedded Systems

2020-08-05
Embedded hardware is everywhere you look today from your vehicle’s infotainment system to refrigerator to medical devices and everything else in-between. With so much exposure one would think that such devices are secure against attack; however, sadly for many devices this is not the case. For proof, just look no further than your local news reports. They are full of reports on devices being hacked. So, as engineers, how do we go about first identifying and mitigating (or capitalizing) the potential security vulnerabilities within these devices?

Photography for Accident Reconstruction, Product Liability, and Testing

2020-02-11
Many technical projects, most vehicle and component testing, and all accident reconstructions, product failure analyses, and other forensic investigations, require photographic documentation. Roadway evidence disappears, tested or wrecked vehicles are repaired, disassembled, or scrapped, and components can be tested to failure. Photographs are frequently the only evidence that remains of a wreck, or the only records of subjects before or during tests. Making consistently good images during any inspection is a critical part of the evaluation process.

Unsettled Domains Concerning Autonomous System Validation and Verification Processes

2019-12-20
EPR2019012
The Federal Aviation Administration (FAA) and the Department of Transportations' (DOT's) National Highway Traffic Safety Administration (NHTSA) face similar challenges regarding the regulation of autonomous systems powered by artificial intelligence (AI) algorithms that replace the human factor in the decision-making process. The validation and verification (V&V) processes contribute to the implementation of the correct system requirements. The V&V process is one of the steps of a development lifecycle starting with the definition of regulatory, marketing, operational, performance, and safety requirements. They define what a product is, and they flow down into lower level requirements defining control architectures, hardware, and software. The industry is attempting to define regulatory requirements and a framework to gain safety clearance of such products.

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.

2019-28-2388
India has gone through a lot of transformation over the last decade. Today it is the 6th largest and one of the fastest growing economies in the world. Rising income level, increased consumerism, rapid growth in urbanization and digitization have attributed to this change. Government focus on “Make in India” for promoting trade and investment in India have ensured that India emerge as one of the largest growing economies in the world. The automotive industry played a pivotal role in the manufacturing sector to boost economic activities in India. The passenger car market has increased 3 times over the last decade and it has led to increased mobility options for many people across India. However, this has put concerns on the country’s energy security and emission levels. According to IEA’s recent report on global CO2 emission, 32.31 Gt of CO2 emissions were from fuel combustion in 2016, out of which transport sector contributed ~25%.

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.

Methodology for failure simulation Using 4 corner 6 DOF Road load simulator of Overhanging Components: An Experimental Approach

2019-11-21
2019-28-2404
Nowadays, Road Load Simulators are used by automobile companies to reproduce the accurate and multi axial stresses in test parts to simulate the real loading conditions. The road conditions are simulated in lab by measuring the customer usage data by sensors like Wheel Force transducers, accelerometers, displacement sensors and strain gauges on the vehicle body and suspension parts. The acquired data is simulated in lab condition by generating ‘drive file’ using the response of the above mentioned sensors. For generation of proper drive file, not only good FRF but ensuring stability of inverse FRF is also essential. Stability of the inverse FRF depends upon the simulation channels used. In this paper, an experimental approach was applied for focused failure simulation of engine mount, one of such low correlation zone, with known history of failure.

Design and Development of Constant speed diesel engine up to 20 bar BMEP with Inline FIS Remesan CB, Sanjay Aurora, Vasundhara V Arde, Vishal Kumar, Om Prakash Yadav, Piyush Ranjan Eicher Engines (A unit of TAFE Motors & Tractors Ltd.) Abstract Development trend in diesel engine is to achieve more power from same size of engine. With increase in brake mean effective pressure (BMEP), the peak firing pressure will also increase. The methodology to control the peak firing pressure on higher BMEP is the major challenge. We achieved better SFC with CPCB II emission targets on a constant speed engine. This study involves a systematic approach to optimize combustion parameters with a cost effective and robust inline Fuel Injection System. This paper deals with the strategies applied and experimental results for achieving the power density of 25kW/lit with Inline FIP by keeping lower Peak firing pressure.

SIMULATION OF SOFTENING AND RUPTURE IN MULTILAYERED FUEL TANK MATERIAL

2019-11-21
2019-28-2557
Research and/or Engineering Questions/Objective Plastic automotive fuel tanks made up of blow molded, multi-layered, high-density polyethylene (HDPE) material can take complex shapes with varying thickness. Accidental drop of fuel tank from a height during handling can lead to development of cracks. Damage can also occur due to an impact during a crash. This can be catastrophic due to flammability of the fuel. The objective of this work is to characterize and develop a failure model for the fuel tank material to simulate damage and enhance predictive capability of CAE for chassis and safety load cases. Methodology Different aspects were considered to develop a characterization and modelling strategy for the HDPE fuel tank. Material properties can be influenced by factors such as, service temperature, rate of deformation, state of stress etc.
