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 ...

Removing carbon build up from your direct injection gasoline engine is easier than you might think! I'd always heard that you ...

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 ...

Flash boiling occurs when liquid fuel under high pressure enters an environment whose pressure lies below the liquid’s saturation pressure, driving rapid vapour nucleation and explosive atomisation.

The DM-i setup combines a 1.5-litre turbocharged direct injection petrol engine with two electric motors and a larger battery pack.
