If you ask any modern automotive nerd to name the first vehicle to feature a direct-injection diesel technology, you will likely get one of two answers. The Volkswagen Audi Group loyalist will point ...

The video explains how modern direct-injected engines can develop fuel dilution, carbon buildup, oil consumption and PCV ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.

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 ...
