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 38%
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

Quick commerce divide: Metros lead as demand booms in top cities; small towns drag with just 20% share despite 150% growth
India's quick commerce industry is sprinting ahead in metros, but non-metro cities continue to trail behind, held back by weak demand, low digital adoption, and entrenched local shopping habits, according to a report by Redseer. Tired of too many ads? go ad free now The sector expanded nearly 150% year-on-year in the first five months of 2025, driven by aggressive rollout of dark stores, rapid category expansion, and intense competition. Yet, non-metros account for only a little over 20% of gross merchandise value (GMV), despite platforms having a presence in more than 100 cities, PTI reported. This share is significantly lower than their 60–70% contribution to the total retail market in the top 100 cities, highlighting both a large untapped opportunity and the difficulty of building a profitable business in these locations. Daily orders per dark store see a steep fall beyond the top 10–15 cities, dipping below 1,000 — and further under 700 in the next 20. According to Redseer, most non-metros tend to plateau before reaching 1,000 orders per day, underscoring sluggish demand in these markets. Challenges range from low digital literacy and trust in online platforms to sparse population densities and localised preferences that don't align with standard quick commerce offerings. Consumers in smaller cities often maintain strong relationships with local kirana stores that offer informal credit and free home delivery, reducing the incentive to shift online. Meanwhile, the cost of servicing these markets remains high, as lower order volumes force larger delivery radii and higher payouts. These dynamics push up the breakeven throughput for dark stores in smaller cities by 1.5 to 2 times compared to metros, Redseer said. Tired of too many ads? go ad free now Education hubs like Prayagraj and Varanasi, and affluent towns such as Chandigarh, are bucking the trend with encouraging demand. 'Quick commerce has unlocked incredible convenience in metros, but scaling it beyond demands more than just replication. Success in smaller cities will hinge on hyper-local strategies, deeper demand and supply understanding, and operational agility,' said Kushal Bhatnagar, Associate Partner at Redseer Strategy Consultants, the agency quoted. According to estimates by global consultancy Kearney, India's quick commerce grocery market is likely to triple in size from 2024 to 2027, reaching Rs 1.5–1.7 lakh crore.

Sony Semiconductor Solutions Unveils Advanced CMOS Sensor for Mobile Devices, Delivering Superior Imaging and High Dynamic Range Even While Zooming
New Delhi [India], June 27: Sony Semiconductor Solutions Corporation (SSS) has announced the launch of the LYT-828, a new 50-megapixel*1 CMOS image sensor. Part of the LYTIA brand–a new lineup of mobile image sensors–the LYT-828 offers an impressive dynamic range of over 100 dB, effectively reducing blowout in bright areas while minimizing noise and blackout in darker regions. A successor to the LYT-818, this 1/1.28-type sensor is primarily designed for both main and sub-cameras in smartphones. While retaining the core features of its predecessor, it introduces the newly developed Hybrid Frame-HDR (HF-HDR) technology for enhanced image quality. HF-HDR is an advanced HDR solution that integrates multiple HDR techniques–combining traditional single-frame HDR using dual conversion gain (DCG) with multi-frame HDR that merges short-exposure frames and DCG data at the application processor stage. This fusion results in an industry-leading dynamic range of over 100dB among Sony Semiconductor Solutions' mobile CMOS sensors. The sensor effectively reduces highlight blowout in bright areas and minimizes blackout in dark scenes, producing visuals that more closely match human visual perception. Additionally, the integration of Loss-Less Exposure (LLE) technology allows greater flexibility in exposure control, optimizing light utilization and improving the signal-to-noise ratio (SNR). Notably, HF-HDR retains its full capabilities even during zoom, ensuring consistent high-quality imaging throughout. The LYT-828 also features a proprietary circuit developed by Sony Semiconductor Solutions (SSS) that efficiently converts the charge from photodiodes into voltage, significantly reducing random noise (RN). This allows for the capture of highly detailed images even in low-light environments, with minimal grain caused by noise. Additionally, the sensor is designed for lower power consumption, particularly within its logic circuits, enabling continuous HDR functionality–even during preview mode and video recording. As a result, users can shoot HDR images and videos that closely match what was displayed during the preview on their smartphone screens. New HDR technology that delivers over 100 dB of dynamic range performance HF-HDR is an advanced HDR technology that enhances dynamic range by combining composite data from single-frame HDR–captured using dual conversion gain at different gain levels–with short-exposure frames on the application processor at a later stage. This innovative approach significantly boosts dynamic range performance to over 100 dB, surpassing that of conventional HDR methods. The inclusion of Loss-Less Exposure (LLE) technology further enhances image quality by allowing greater flexibility in exposure control, leading to improved signal-to-noise ratio (SNR). Notably, HF-HDR maintains its high dynamic range even during zoom operations by switching to full resolution, ensuring consistent, high-quality imaging even in scenes with strong contrast. Ultra-high conversion gain (UHCG) technology minimizes random noise in low light, enabling vivid imaging UHCG is a circuit technology that efficiently converts electrical charge to voltage, significantly reducing random noise and graininess in low-light conditions. This enhances image clarity and improves color gradation, ensuring better reproduction in dark environments. Low-power design for constant use of HDR Typically, showing HDR previews on a smartphone screen increases power consumption and can lead to device heating, which may limit the availability of HDR preview. However, this sensor is designed with low-power logic circuits, enabling continuous HDR functionality without overheating. As a result, users can preview images and videos in true HDR quality and capture them exactly as seen on screen, enhancing the overall shooting experience.
