“…The results of the studies shown that the suggested approach outperforms the average accuracy of current classifiers by 7.03% and obtains a classification accuracy of 92.48% when applied to a massive dataset of ECU data. A special design for an Engine Control Unit (ECU) was givrn by P. Sridhar Acharya and K. Krishna Prasad [2] which will control the firing of engine based on the density of a vehicle in the city along with the accelerator given by the rider/driver. Using GPS techniques the entire information of the vehicle like speed in kmph, longitude, latitude, timing factor etc.…”

This research project is crucial to understanding how motorcycle design is influenced by transitioning from Bharat Stage (BS) 4 to Bharat Stage (BS) 6 emission standards, particularly in the context of the KTM RC390 models from 2017 and 2020. The importance of this research is twofold. To begin with, it lets us evaluate how changes to emission standards would affect things like engine management systems, emissions control technologies, environmental compliance, fuel economy, performance, and performance on motorcycles. The second benefit is that it gives people the tools they need to make educated decisions when buying motorbikes. In order to make my results more understandable, I want to use data visualization tools such as Matplotlib, Tableau, and Google Charts to show the differences between the two models. Next, I will create an intuitive website that presents this data in an easy-tounderstand format. I want to do this by making use of the state-of-the-art FRAMER tool for website creation and design. Essentially, this study connects motorcycle design to pollution requirements, which helps consumers make better selections and uses technology to display facts clearly.

“…[2] Transmission loss is the parameter that is most frequently used to assess the sound radiation properties of a silencer. [3] The Transmission Loss computation is typically the most used technique for describing a system's acoustic performances. [4] This work provided an overview of sound transmission loss and discussed its substantial environmental effects.…”

The Helmholtz resonator is one of the basic elements to attenuate low-frequency noise and increase sound transmission loss in a muffler for particular low frequency zone. It can be enhancing the performance without any change in the geometry of the muffler. It can greatly reduce the high-intensity noise in low-frequency zones. A comparative study has been carried out by implementing the two and three resonators arranged in series arrangement at optimum spacing for increasing transmission loss. The model of Helmholtz resonator at wavelength 1000 mm at different spacing like (closely spaced: -(4), 1stantinode: -(4) and 1st node: -(2) ) were prepared by using wave build 3-D and simulating above condition on wave 1-D module. This work is also validated by simulating the same geometry on Comsol tool for the mentioned spacing. This attempt gives a comparative study about perfect spacing during use of more than one resonator in a series. The neck and cavity ratio are taken as 2 and 1.85 respectively for the modelling of an identical resonator. The Conclusion shows that, at (4) resonator gives the maximum attenuation at 340 Hz cut-off frequency in low-frequency zone.

“…The ability of a vehicle's exhaust system to reduce noise and function generally acoustically is directly impacted by the amount of sound transmission loss in hybrid mufflers (Kashikar et al, 2021). Innovative methods that concentrate on changing muffler design and using cutting-edge sound-absorbing materials have been developed in the quest for quieter and more effective mufflers (Siano and D'Agostino, 2015).…”

It is well known that baffled exhaust mufflers enhance sound transmission loss while lowering noise emissions. Sound transmission loss can be further reduced by adding sound-absorbing material inside the silencer. It has been demonstrated that carefully placed baffles in exhaust silencer systems improve acoustic performance by successfully lowering noise emissions. Sound waves are redirected and disrupted by baffles, which lessens the transmission of undesired noise and creates a more controlled and tranquil acoustic environment. The incorporation of sound-absorbing materials into mufflers is a significant development in noise control technology. Specialized materials are added to the muffler to improve sound wave absorption and drastically reduce noise emissions. This novel method not only enhances acoustic performance but also improves a variety of applications—from industrial gear to automobile exhaust systems—making them quieter and more enjoyable to use. A silencer was constructed for this research project using the finite volume method. The design's efficacy was demonstrated through experimental validation. The research project then used the finite volume technique to produce a silencer with the same dimensions. It then adjusted the design based on different flow percentages, adding a baffle and making pipe perforations, until the optimal silencer design was found. Additionally, this approach provides an optimal design and indicates which sound-absorbing material has the largest sound transmission loss.
