With the rapid development of new energy vehicles, at the Shanghai Auto Show on April 23, Changan Automobile took a new path and continued to deepen the internal combustion engine technology, and recently made a major breakthrough, which attracted widespread attention inside and outside the industry. Changan Automobile's new self-developed 500Bar ultra-high pressure direct injection new Blue Whale engine was unveiled. The engine is equipped with the state-of-the-art Engine Performance Optimization technology, which greatly improves its capabilities and combustion efficiency. Compared to conventional engines, the power output is significantly improved, resulting in a more powerful driving experience. As the core component of fuel vehicles, the engine has an extremely complex structure, but the pursuit of an excellent engine is very simple, that is, to improve the power performance while reducing fuel consumption, in addition to taking into account excellent reliability and quietness, in terms of fuel economy, the new Blue Whale engine performs well. The mass-produced models equipped with this engine have a measured range of more than 1,000 kilometers on a tank of fuel, and the cost per

Shanghai, April 22, 2025 - AutoTech Expo 2025, the world's leading automotive parts event, grandly opened today at the National Exhibition and Convention Center (Shanghai). This exhibition, themed "Intelligent Drive for the Future · Green Mobility", focuses on core components such as crankshafts, sensors, gears, filters and bumps, attracting over 800 exhibitors from more than 40 countries. Showcase the latest technological achievements and industry trends.1.Crankshaft innovation in the era of electrificationWith the continuous increase in the market share of hybrid and pure electric models, crankshaft technology has undergone a major upgrade. Many enterprises have launched carbon fiber reinforced composite material crankshafts, which are 40% lighter than traditional steel crankshafts and 20% stronger, significantly enhancing the efficiency of new energy engines. In addition, the integrated crankshaft-motor design becomes the focus, which can reduce energy loss and is suitable for the next generation of extended-range electric vehicles.2. Intelligent sensors: The core support for autonomous drivingIn the high-precision sensor exhibition area, manufacturers showcased a new generation of multi-in-one intelligent sensing systems, which can monitor engine operating conditions, emission data and the health status of components in real time, and achieve cloud diagnosis through the Internet of Vehicles (V2X).AI vision sensor: Used for monitoring the condition of autonomous driving gearboxes and providing early warnings of wear.Hydrogen energy pressure sensor: Specifically developed for hydrogen fuel cell vehicles, it is corrosion-resistant and high-pressure resistant, facilitating the commercialization of hydrogen energy.3.
