MNNIT develops tech to increase vehicle lifecycle
Experts from Motilal Nehru National Institute of Technology ( MNNIT ), Prayagraj, have developed a groundbreaking engine cylinder liner that promises to revolutionise the vehicle lifecycle and sustainability by reducing lubricant leakage and emissions. This innovation, achieved through protruding surface texturing technology, is expected to greatly enhance engine efficiency and reduce fuel consumption. The engine cylinder linear piston ring pairs (commonly known as CLPRs) significantly reduced friction and wear by 38% between the piston ring and the cylinder liner, compared to conventional designs. With less fuel being burned, the engine emits fewer harmful gases, thereby contributing to environmental conservation. This development holds major promise for the automobile sector, particularly for two-wheeler and four-wheeler engines, and is being hailed as a major step forward for India's automotive industry. The research carried out by assistant professor at the department of mechanical engineering of MNNIT Allahabad, Tej Pratap, and his research scholar, Govind Murari, has been published in the UK's renowned Journal of Process Mechanical Engineering. According to Pratap, the cylinder linear with different configurations of protruded textures was fabricated using a five-axis flexi fibre nanosecond pulsed laser, a high-precision device capable of micro-scale surface engineering application. "To verify its performance, the new cylinder linear underwent rigorous testing on a tribometer machine under SAE 10W-30 lubricants at the National Institute of Technology (NIT) Calicut. The tests evaluated the CLPR's performance for five different protruded textures and friction and wear parameters. All of them yielded positive results," he said. Key improvements include a reduction in oil leakage and friction at the CLPR's interface, leading to decreased emission of harmful gases. Additionally, the efficiency and durability of the CLPRs were significantly enhanced, ensuring long-term functionality under variable loadings and engine conditions. For a smooth ride Friction and wear between the piston ring and the cylinder liner were reduced by 38per cent. By reducing oil leakage and friction where the piston ring and the cylinder linear meet each other, harmful gases emitted from the vehicle were reduced Efficiency and durability of CLPRs were increased so that they work well for a long lifecycle without compromising their performance

MNNIT to study lightning impact on planes
Prayagraj: A team of scientists from Motilal Nehru National Institute of Technology (MNNIT) are working on a project to determine the exact mix of materials that can reduce the effect of lightning strikes on aircraft. Funded by the Defence Research and Development Organisation (DRDO), the project, costing around Rs 60 lakh, was awarded to Ashutosh Kumar Upadhyay, associate professor in the applied mechanics department at MNNIT. The research puts spotlight on the May 21 incident wherein the front portion of a plane travelling from Delhi to Srinagar was damaged due to a storm and lightning strike jeopardizing the lives of 227 passengers. Upadhyay said the damage to planes due to lightning is a serious problem. "The cause of damage to planes from lightning will be investigated. Research is being conducted to identify which mixed substances can reduce the effect of lightning. Planes are at risk from both lightning and charge because they become a medium for the current between two clouds. This study focuses on composite panels used in modern aircraft. It will be analysed how lightning strikes affect the structure, temperature, electrical flow, and mechanical strength of the panel," said Upadhyay. He said electrical, heat and mechanical effects will be combined through multi-physics modelling techniques to understand the type of damage and its impact on the aircraft. Based on this, a new code will be prepared, and the simulation software will be updated with this code, allowing the electrical resistance capacity of the new material to be easily tested. This will reduce the effect of lightning on the aircraft. DRDO has assigned this project for three years. A JRF will be appointed for the project.

Maha Kumbh's crowd mgmt strategies can be replicated in temples: Expert
Prayagraj: The 2025 Maha Kumbh is poised to set a benchmark for future religious events. Experts who participated in the Kumbh Fellow Learning Program at Motilal Nehru National Institute of Technology here on Saturday recognised the potential of the Prayagraj Maha Kumbh as a model for temple management across the country. Tired of too many ads? go ad free now Temples are revered not only as places of worship but also as vibrant representations of India's spiritual and cultural essence, embodying the nation's religiosity, cultural prosperity, and social harmony. Suresh Haware, a noted temple management expert, emphasised that the crowd management strategies employed during the Maha Kumbh, such as e-queue management, CCTV surveillance, and IT-based administration, can be adapted to manage large gatherings at major temples. He also highlighted the need to train a dedicated workforce in temple management to effectively implement these innovations. Anubhav Rawat, the program's nodal officer, outlined the structure of the Kumbh Fellow Learning Program, which consisted of three sessions. The first session featured Prof. RS Verma, the institute's director, as the chief guest, followed by a lecture by Haware on Maha Kumbh and temple management. In the second session, three Kumbh Fellows shared their experiences and insights from the Maha Kumbh, with WG Prasanna offering his perspectives as the chief guest. The third session saw the remaining Kumbh Fellows presenting their findings. A total of 46 Kumbh Fellows participated in the program, which also had SDM Abhinav Pathak and regional tourist officer Aparajita Singh in attendance.

MNNIT student of BTech hailing from Chhattisgarh ends life
Prayagraj: A 20-year-old BTech first-year student of MNNIT (Motilal Nehru National Institute of Technology), Allahabad, allegedly committed suicide in his hostel room inside the institute campus on Thursday, police said. However, no suicide note was recovered from the room. The deceased, Nikesh Kumar Rohidas, was a resident of Semariya village of Janjgir–Champa district of Chhattisgarh. Additional DCP (city) Abhijeet Kumar said: "The deceased was pursuing his BTech first year in computer science and an inmate of room no. 101 of Vivekanand Boys Hostel. The police have seized his mobile phone and laptop for further investigations. The motive behind suicide is not known yet." Sources said the deceased was to appear in his last exam of the second semester on Thursday. When his friends asked him to come for the exam, he assured them that he would be arriving within five minutes. However, he didn't appear in the exam, and the hostel mates found his room closed from inside upon their return. Feeling suspicious, they called up hostel and college authorities, who then called up the police. Police broke the door open to find the victim's body. His fellow inmates told police that he had even packed his belongings on Wednesday to return to his native place after the exams were over on Thursday. Police said the body had been sent for postmortem and further probe was on. Chief warden Prof Naresh Kumar said the parents of the victims have been informed.
