Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner ...

Gasoline direct injection (GDI) engines have become prevalent in modern light-duty vehicles owing to their improved thermodynamic efficiency and lower fuel consumption compared with ...

Turbo Fuel Stratified Injection technology for gasoline engines was once a remarkable innovation that has since become quite commonplace. Traditional fuel-injected engines that don't use direct ...

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...

Before the turn of the millennium, you wouldn't find many people complaining about carbon deposits on engine valves. However, all of that changed as gasoline direct injection (GDi) went mainstream in ...

Chevron says its new Techron cleans GDI injectors better, plus new rewards make switching easier.

Until the early 1990s, many gasoline engine designs relied on carburetors to produce the fuel-air mixture needed to make the power that makes a car move. However, as the regulations around fuel ...

Twenty years ago, a group of original equipment manufacturers (OEMs) established the voluntary TOP TIER™ standard to enhance fuel detergency and optimize engine performance. Recognizing the ...
