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.

Automobile Exhaust Emmision Control- A review

2019-11-21
2019-28-2382
Since the 20th century increase in the number of cars in the major cities is been a point of concern because of the toxic gasses being emitted from the engine of an automobile. These gasses are polluting the atmosphere and degrading the air to breathe. The main gasses responsible for the degradation of air quality are carbon monoxide, hydrocarbon and oxides of nitrogen. There is a necessity to find ways to reduce the pollution emitted into the atmosphere from the automobile. The source of emission is either evaporation from fuel tank or carburetor which is easy to be dealt with or harmful gasses due to improper combustion which is a concern for the environment. The two ways to reduce these emissions are, modification in the engine to minimize the production of harmful gases and to treat the harmful gasses emitted from the engine before blowing it into the atmosphere from the exhaust. Catalysts help to break harmful gasses into smaller compounds that are environment-friendly.

In high speed race cars, aerodynamics is an important aspect for determining performance and stability of vehicle. It is mainly influenced by front and rear wings. Active aerodynamics consist of any type of movable wing element that change their position based on operating conditions of the vehicle to have better performance and handling. In this work, front and rear wings are designed for race car prototype of race car. The high down force aerofoil profiles have been used for design of front and rear wing. The first aerodynamic analysis has been performed on baseline model without wings using CFD tool. For investigation, parameters considered are angle of attack in the range of 0-18˚ for front as well as rear wing at different test speeds of 60, 80, 100 and 120 kmph. The simulation is carried out by using ANSYS Fluent. The simulation results show significant improvement in vehicle performance and handling parameters.

2019-28-2394
Role of Wheel and underbody Aerodynamics of vehicle in the formation of drag forces is detrimental to the fuel (energy) consumption during the course of operation at high velocities. This paper deals with the CFD simulation of the flow around the wheels of a bus with different wheel housing arrangements. Based on benchmarking, a model of a bus is selected and analysis is performed. The aerodynamic drag coefficient is obtained and turbulence around wheels is observed using ANSYS Fluent CFD simulation for different combinations of wheel-housing- at the front wheels, at the rear wheels and both in the front and rear wheels. The drag force is recorded and corresponding influence on energy consumption of a Bus is evaluated mathematically. A comparison is drawn between energy consumption of bus body without wheel housing and bus body with wheel housing. The result shows a significant reduction in drag coefficient and fuel consumption.

Active aerodynamics can be defined as the concept of reducing drag by making real-time changes to certain devices such that it modifies the airflow around a vehicle. Using such devices also have the added advantages of improving ergonomics and performance along with aesthetics. A significant reduction in fuel consumption can also be seen when using such devices. The objective of this work is to reduce drag acting on a passenger car using the concept of active aerodynamics with grill shutters and air dams.

Any physical body being propelled through the air has drag associated with it. Drag will be created on the surface of the vehicle due to the flow separation at the rear end. In aerodynamics the flow separation can often result in increased drag particularly pressure drag, to delay the flow separation, the vortex generators are used on the roof end of the vehicle just before the point of flow separation. The objective of this project is to perform aerodynamic analysis of commercial vehicle using active vortex generators concept. First, the aerodynamic analysis of a baseline commercial vehicle model is performed and same is validated with the scaled model by using a wind tunnel test. Further analysis has been done by using active vortex generators concept with variation of angle of attacks for vehicle speed of 50, 70, 90 kmph. Also, analysis has been carried out for six different yaw angles. The simulation is carried out with the use of ANSYS Fluent.

Experimental Investigation on Performance and Emission Characteristics of a Single Cylinder CRDI Engine Fueled with Diesel-Methanol Blend

The diesel engine is widely used for its high thermal efficiency and better fuel conversion efficiency. However, increasing usage of petroleum fuel and environmental degradation motivates to use renewable biofuels as a replacement to conventional diesel. Biofuels produced from non-edible sources can be used as a partial substitute of diesel for the significant growth of fuel economy and reduction of environmental pollution. Methanol can be implemented as a blended fuel in the diesel without affecting engine design. In this study, the effect of diesel methanol blends and injection parameters such as fuel injection pressure (FIP)and start of injection (SOI) on a common rail direct injection (CRDI) diesel engine performance and emission were investigated. Four blends were prepared by mixing diesel with methanol (5%, 10%, 15% and 20% by mass) and adding a certain amount of oleic acid and iso-butanol to get a stable blend.

The future of mobility is being driven towards fully autonomous driving. As a result, people spend majority of the time in vehicles for chores other than driving. The focus of automotive makers shifts towards providing best-in-class passenger comfort. One of the least focused area in passenger comfort is vehicle interior cleanliness which requires periodic human intervention. An intelligent vehicle can outsmart a human by self-caring to maintain the cleanliness elements on floor, seat and roof. This paper addresses subjects like wetness, dirt and stains in the vehicle interior utilizing the capability of Interior sensing platform. An internally mounted camera in the vehicle can capture images of the interior and apply image processing techniques to identify the subjects mentioned above. The wetness on the floor mats can lead to moldy odor, corrosion, failure of the electronic components in the car.
