However, the usage of bio-butanol decreases the essential properties of the final blend significantly. This is study is to overcome this limitation by addition of castor oil into the base blend (containing 20% bio-butanol) by enhancing the properties. The study starts with the addition of castor oil (1% to 10%) and testing the properties. One blend is chosen by comparing the properties considering diesel fuel properties. The result depicts the blend of bio-butanol with 10% and 15% of castor oil is found suitable and this blend produces higher thermal efficiency, lower oxides of nitrogen and smoke, and higher heat release and pressure when fueled in the engine at higher brake powers. However, this blend produces higher hydrocarbons and carbon monoxide at low brake power. This study enhances the use of utilization of biobutanol blends in the engine for a long-term duration as the kinematic viscosity is competent to diesel fuel which lowers the friction in the parts of the engine. 20BB80D COBD 10 and 20BB80D COBD 15 produce 8.3% and 5.2% which are slightly low EGT by taking the reference values of diesel. Maximum pressure when fueling with 20BB80D COBD 10 and 20BB80D COBD 15 are low by 3.1% and 1.8% while comparing the diesel values Emissions of oxides of nitrogen are found to be significantly low by 13.2% and 3.4% and the smoke emissions are high by 10.2% and 3.2% (comparing diesel values). Also, the saving of fossil fuel resources through the decrease in imports is significant. There is no modifications necessary in the engine to use this blend.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135142181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, the main objective of the vehicle suspension system is to improve ride comfort, road handling and vehicle stability. A suspension system plays a vital role in a smooth and safe riding experience. So, an analysis of the suspension system should be done, and the results should be in the standard range. In this paper, the simulations of a quarter and half car passive spring and air suspension were analysed for ride comfort and suspension travel by mathematical modelling of the quarter-and-half car with the help of a system of equations. As these mathematical equations cannot be solved directly, these equations are solved with the help of library blocks of MATLAB/ Simulink software by giving different road profiles as single bumps, step functions and irregular road profiles as excitations for the suspension system.

There are many problems with the existing EV charger and one of them is the poor power factor. The main reason for this is the Diode Bridge Rectifier (DBR), which is used at the source side of the existing charger. In the new configuration instead of DBR a landsman converter is used at the source end. The landsman Converter further cascaded to an Isolated Fly back converter which charges the battery. The PI controller is used to control the DC output voltage of the landsman converter to generate the required voltage given as a reference. The Flyback converter is also controlled using the PI controller. Comparison is made between both configurations by comparing the THD (Total Harmonic Distortion) response of both circuits. Furthermore, a new type of configuration that uses both DBR and Landsman converter is simulated in MATLAB and results are compared with other configurations.

The goal is to take advantage of the benefits of both biodiesels. The problem being addressed is that biodiesels have lower performance and higher emissions compared to regular diesel. The study looks at using a blend of diesel fuel, Linseed oil methyl ester (LOME), and Calophyllum inophyllum methyl esters (CIME) in a single-cylinder diesel engine to evaluate performance and emissions. The biodiesels were made using a trans-esterification process from prestained oil. The blends were labeled B0, B5, B10, B15, and B20. B5 demonstrated the best performance with increased Brake Thermal Efficiency (BTE) and reduced Brake Specific Fuel Consumption (BSFC). The B5 blend had a maximum increase in BTE of 3.92% compared to diesel fuel, and a decrease in BSFC of 10% compared to diesel (B0). The LOME/CIME blend lowered NOx emissions by 6.15% with B5 blend at full load conditions. This suggests that the use of ternary blends such as calophyllum inoplyllum biodiesel and linseed biodiesel can combine the advantages of different feedstocks and be a good alternative fuel option for high-compression engines.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A part integral to this overhaul of EVs is the implementation of wireless charging station. It is necessary to set up a wide range of charging networks in a user-friendly environment in order to facilitate the adoption of electric transportation. As a result, the main goal of this work is to present a viable substitute solution that uses Wireless Power Transfer (WPT) technology to charge electric vehicles (EVs) without any plug-in issues. This work proposes on a static wireless power transfer technology for Electric Vehicles. A high-efficiency wireless power transfer system for electric vehicles is virtually designed using matlab with a maximum power point tracking for solar panel, DC-DC and AC-DC converter. A scaled down version of the prototype for the same is built with more environmental friendly solar power supplied wireless charging and tested to verify the feasibility and the proposed design. This work highlights the potential of WPT as a solution to the challenges of EV charging infrastructure. The use of solar energy makes the charging process more sustainable, and the evaluation of transformer structures provides insights into how to optimize the charging process for future EV development. This charging station is designed for fast charging and to reduce carbon footprint.

In a manual transmission, the synchronizers play a vital role in defining the gear shift quality. Manual transmission vehicles are getting refined for a pleasant driving experience. The gear shift quality is one of the unique selling points for the vehicle, so the automakers are focusing on the reduction of the gear shift forces. In a manual transmission, the synchronizers are used to match the speed difference between the upstream and downstream inertia for the gear-shifting process. The synchronizers have conical friction surfaces to generate friction and cone torque. The increase in cone torque reduces the gear shift impulse. The cone torque can be increased with mismatch tolerance in the frictional surfaces. In this technique, two cone angles are used for the frictional surfaces. The applied force on the synchronizer tooth compresses the synchronizer ring and closes the non-uniform clearance between the frictional surfaces. This generates uniform surface pressure and increases the cone torque. The design is validated for the increase in cone torque using the synchronizer test rig. The mismatch tolerance increases the cone torque and reduces the synchronization time. Due to the mismatch, after the synchronization, the synchronizer ring tries to come back to its original position. This avoids the sticking of the synchronizer ring over the gear cone. This quickly reduces the gear shift forces after synchronization. The gear shift quality is validated on the vehicle using the Gear Shift Quality Analyzer. The results confirm that the mismatch tolerance enhances the gear shift quality more than the conventional method of tolerancing of the frictional surfaces.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
