International is marching ahead with updates to its S13 Integrated Powertrain to meet federal emissions regulations expected ...

NIO stock looks oversold vs business progress. Q3 2025 shows operating leverage, margin/mix gains and cost discipline guiding ...

The 2026 F1 season hasn't started yet, but there's already a major controversy brewing surrounding engines in cars being ...

Running a single mile — at about a 10-minute pace — consists of 1,700 steps. And each one of those steps produces ground reaction forces of about two and a half times your body weight. And you know ...

Abstract: This paper studies the fundamental limits of the minimum average length of variable-length compression when a nonzero error probability ε is tolerated. We ...

South Korea’s Hanwha Engine has produced what it calls the world’s first X-DF engine equipped with variable compression ratio (VCR) technology for LNG carriers, designed to reduce methane slip by up ...

The innovative engine appears to be a victim of its own complexity. It couldn't come at a worse time for Nissan. Nissan's variable-compression engine once held so much promise. The so-called VC-Turbo ...

Abstract: While deep learning image compression methods have shown an impressive coding performance, most of them output a single-optimized-compression rate using a trained-specific network. However, ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

SAE International Journal of Engines, Vol. 10, No. 3 (June 2017), pp. 817-831 (15 pages) ABSTRACT Increasing compression ratio (CR) is one of the most fundamental ways to improve engine efficiency, ...
