The challenging part is on achieving the stringent emission norms without compromising the engine fuel economy, performance and NVH factors.
The challenging part is on achieving the stringent emission norms without compromising the engine fuel economy, performance and NVH factors. Selection of hardware and attaining an optimal behavior is therefore vital. This article focuses on the evaluation of three different configuration of turbochargers for the same engine in order to meet the BS6 emission norms and performance.
The turbocharger samples used measure same compressor diameter with varying trim ratios. Simulation and testing of turbochargers ensured positive results for confirmation of the system.
Parameters like pumping losses, low speed torque, smoke and compressor efficiency were evaluated and analyzed for all configurations. The safe limits of surge and choke regions of all the Sae papers were also studied.
Technical Paper Any change in vehicle external design affects the aerodynamic characteristics. Generally different types of roof racks are attached on passenger vehicles to carry luggage which affects aerodynamic drag.
The objective of this work is to perform aerodynamic analysis of SUV with roof rack to investigate the change in drag coefficient.
First, the aerodynamic analysis of baseline SUV model to perform with and without generic roof rack at 80 kmph. Further analysis is carried out with different new design of roof rack.
Based on simulation results a scaled down prototype model is fabricated and validated by using wind tunnel test for optimum suitable case. Aerodynamics, Passenger car, Drag coefficient, Roof rack, Fuel economy.
Technical Paper Steering returnability while driving is one of the most important parameter which affects the drive pleasure and handling of a vehicle. Steering returnability refers to the automatic returning response of the steering wheel after taking a full turn while vehicle is being steered during driving.
Evaluating steering response characteristics of any vehicle in a virtual environment at early stage of a product development saves significant development time and cost.
Through this paper an attempt has been made to develop a methodology for selection of suspension hard points which influences steering returnability characteristics for any vehicle at early product design stage.
Conventionally, standard suspension kinematic parameters such as caster angle, king pin inclination KPIetc. Technical Paper Current Global Economic scenario is driven by high quality and innovative products and services available at lower cost.
Design to cost is a management strategy and supporting methodologies to achieve an affordable product by focusing on target cost as an independent design parameter that needs to be achieved with the development of a product. Technical Paper One of the major impacts on tractor performance during cultivation is variation in the soil draft.
The control strategy shall be developed to maintain the soil draft which mainly depends on the sensitivity and accuracy of draft measurement. The main objective of this paper is to carry out the detailed study on draft force impact on tractor three point linkages when used with heavier and bigger implements and identifying an optimum point to measure the draft to increase the sensitivity of draft force measurement.
This paper presents the theoretical calculation of force on the lower link points of three point hitch system in tractor was calculated and selecting an optimum point for the fitment of draft sensor.SAE papers can be published in SAE Special Publications, in SAE Proceedings, in the SAE Transactions, and in various SAE Journals.
"SP" = Special Publications - a collection of Technical Papers presented at a given session in one conference. An agricultural education program is made up of three integrated parts: classroom instruction, FFA and a supervised agricultural experience (SAE).. The SAE is a required component of a total agricultural education program and intended for every student.
Technical Papers. SAE Technical Papers are written and peer-reviewed by experts in the automotive, aerospace, and commercial vehicle industries.
Browse the more than , technical papers and journal articles on the latest advances in technical research and . The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search capabilities of SAE MOBILUS. AND: the results will contain all terms joined by AND.
For example, volvo AND safety, would return results that contain both the words volvo AND safety. © SAE International. All rights reserved. X.
