Fuel mixture preparation in internal combustion engines strongly influences the combustion process. Planar laser-induced fluorescence (PLIF) is commonly used for fuel distribution measurement, however, is mostly reported on moderate- or large-sized engines. Therefore, in the present work, PLIF imaging is applied to measure the in-cylinder fuel distribution in a small port-fuel-injection (PFI), single-cylinder, optically accessible, spark-ignition engine (volume: 110 cm3). Iso-octane was used as a fuel in the present work, and 3-pentanone (15% by volume in iso-octane) was added as a fluorescent tracer. The effect of three different equivalence ratios (i.e. 1.2, 1.0, and 0.8) on in-cylinder fuel distribution was studied with low throttle opening of 25% at 1200 rpm engine speed. PLIF images were recorded at different crank angle degrees during both intake and compression strokes over a swirl measurement plane located at the TDC position. It was found that fuel stratification was present from intake to even late compression. However, no significant change in fuel distribution patterns was noted at different crank angle degrees, considered for the PLIF imaging. Instantaneous PLIF images of…

To achieve accuracy in model development with large-scale actual customer data in low cost and limited time usage of telematics system was adopted. Honda’s OBD II diagnostic connecting device Honda Connect was used as transceiver for this telematics system, which was used as an accessory in Honda vehicles. Data collected with this device with large sample size and regional diversity across India was used in product development for Honda System. Control system development for BSVI vehicles, Idle start stop hardware specification selection and Battery electric vehicle target range study was done with Honda Connect Data.

Design and Development of Single Seat, Four Wheeled All-Terrain Vehicle for Baja Collegiate Design Series

Delhi College of Engineering-Yogesh Sharma, Shubham Garg
Delhi Technological University-Rohit Kumar Garg, Rishabh Raj Bhargava
Published 2015-09-29 by SAE International in United States
There has been a rapid increase in popularity of multipurpose All-terrain vehicles (ATV) across the globe over the past few years. SAE BAJA event gives student-community an opportunity to delve deeper into the nitty-gritty of designing a single seat, four-wheeled off road vehicle. The design and development methodology presented in this paper is useful in conceptualization of an ATV for SAE BAJA event. The vehicle is divided into various subsystems including chassis, suspension, drive train, steering, and braking system. Further these subsystems are designed and comprehensively analyzed in software like SolidWorks, ANSYS, WINGEO and MS-Excel.The 3-D model of roll cage is designed in SolidWorks and analyzed in ANSYS 9.0 for front, rear and side impact along with front and side roll-over conditions. Special case of wheel bump is also analyzed. Weight, wall thickness and bending strength of tubing used for roll cage are comprehensively studied. Suspension geometry is optimized using WINGEO software by performing ride, roll and steer iterations. FEA of suspension parts is done in SolidWorks. Special case of bump-steer is also taken into…
