Direct injection technology has changed how engines make power and use fuel. It allows precise control of the air-fuel mixture, improving both performance and efficiency. However, this design has one ...

Much of mathematics involves so-called forward problems. These problems begin with a model of a physical system — say, a ball rolling down an incline plane — and researchers use parameters, such as ...

With direct injection, engines can run with higher compression ratios, higher boost, and higher efficiencies. The marvel has lead to widespread downsizing of engines, ditching large naturally ...
