Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

Half of the U.S. new-car and truck fleet now is equipped with gasoline direct injection (also known as GDI)—which means the fuel is sprayed straight into the combustion chamber. This begs the question ...

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 ...

Direct injection offers numerous benefits over port fuel delivery but could it be a bigger headache than it’s worth? The automotive industry has gradually switched to direct injection over the past ...

The Kubota Corporation began as a foundry in Osaka, Japan, in 1890. Thirty-two years later, the company produced its first engine, a horizontal, liquid-cooled, kerosene-fueled powerplant designed for ...

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 ...

But the industry shift didn’t happen without complications; these new engines have faced three big challenges: chain wear, fuel dilution, and LSPI. In this video we’ll discuss the differences between ...

Direct injection, as the name suggests, refers to a type of fuel system which introduces fuel directly into an engine's combustion chambers. This differentiates it from conventional injection systems ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...
