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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

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 ...

Mopar — a portmanteau of MOtor and PARts — had humble beginnings as a brand introduced by Chrysler Corporation in 1937 to sell antifreeze. However, today it's best associated with decades of providing ...

To resist exhaust valve seat recession, many late-model cylinder heads have induction-hardened exhaust seats and high-quality valves. For most engines, compression ratio can be significantly lowered ...

Despite the turbulence Nissan has faced over the past few years, some of its technology is undeniably impressive. Perhaps the crowning jewel of this engineering power is its variable compression ...
