Fuel economy (FE) and CO2 reduction through low friction lubricants are important and easy to adopt. Optimization of fluid properties for an application is real challenge. A presentation covers the drivers for vehicle design; emission norms of EU and India; current scenario in India; engine oil specifications for UV/SUV; engine oil design drivers; FE engine oils characteristics; how friction modifier impact; durability performance of oil; and case studies involving FE on SUV and HD vehicle. This is an abstract of a paper presented at the F+L Week 2016 (Singapore 3/8-11/2016). Source

This paper deals with setting of Inspection parameters for selected automotive transmission parts in various bench tests. This paper we are discuss about critical dimension's measured for particular type of test. It is not possible to measure all the dimensions of a component for doing a particular test. This is due to time constraints set by program delivery deadlines. From above statement it can be deduced that it is almost impossible to measure all dimensions of a component. A bench level test may consist of two major tests. They are maximum load test and gear shift durability test. The maximum load test deals with gear box durability test and torque carrying capacity of gearbox. Parameters to be measured for some of above parts will be identified. More importantly it will also identify see reasons for that parameter to be measured. Copyright © 2013 SAE International. Source

This paper deals with an analytical engineering method to reduce the stresses in a shaft. The specification and design of transmission shaft is of special significance in the layout of the vehicle transmissions. In this paper an analytical engineering calculation of typical automotive transmission shaft' stresses is done. Later calculated stresses are validated by C.A.E analysis. In the calculations most of the shaft design methodology is shown in detail. The calculations reduce the C.A.E iteration to almost to 1 as correlation is found between calculations and C.A.E analysis. Copyright © 2013 SAE International. Source

The Technical paper present the mathematical model that predicts the radiator thermal performance curves for different airflow and coolant flow. This model was modeled using the signal library of AMEsim software. The model accepts the inputs of radiator parameters such as Air flow, Ambient temperature, Core size, Tube pitch, FPDM, No of rows, Louver pitch, Fin thickness, Louver angle Tube section data, Tube thickness, Coolant lpm, Max allowable coolant temp. The output of this model is the Radiator Performance Curve. This model is quick tool to work out approximate size of radiator to start system level packaging, Hence the Product Development time can be saved in Radiator Sizing. © 2013 SAE International.

Crashworthiness enhancement of vehicle structures is a very challenging task during the early design development process. Major factors influencing occupant injury in frontal impact are vehicle front crush space, crash pulse severity, restraint properties and occupant packaging space. This paper establishes a methodology to define suitable criterion that will guide the designers to select the optimal values of the above mentioned parameters during the early phase of the vehicle development. The usage of lumped mass models, pulse characterization techniques were explored to validate the results. Efficient crash energy management, the concepts of ride down and restraint efficiency parameters were also discussed in the paper. Copyright © 2013 SAE International. Source
