Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

Toyota makes some of the most durable trucks in the world—they’re so long-lasting, in fact, that they often go a full decade without major updates. That might change soon if an engine described in a ...

2.Reduced engine rpm (without attending losses in net torque) tend to improve overall fuel economy and driveability. 3.Treat multi-cylinder engines as a combination of several single-cylinder engines, ...

According to co-founder and CEO Alec Schkolnik, the X Engine design combines the high compression ratio and direct injection of a diesel engine with the constant volume combustion process of an Otto ...

Airbus Helicopters has completed the first flight of a lightweight, high-compression engine (HCE) on an H120 helicopter technology demonstrator. The 6 November sortie of the light-single, modified ...
