The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

Gasoline direct injection, or GDI, is one of the most crucial bits of technology in the modern internal combustion engine. In engines equipped with GDI, highly pressurized gasoline is sprayed directly ...

We'll discuss the tuning flexibility of port injection, the advantages of the cooling effects of in-cylinder direct injection, as well as how dual injectors (both port & direct) can offer the benefits ...

The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...

SAE International Journal of Engines, Vol. 13, No. 1 (2020), pp. 77-92 (16 pages) At gasoline direct injection, light-duty engines operated with homogeneous, stoichiometric combustion mode, ...

Typically, a well will produce at its highest production rate at the beginning of the production cycle; and then production will wane. In an effort to increase production from both oil and natural gas ...

Knowing the inner workings of a vehicle comes with its set of benefits. You know the risks associated with potential issues, understand the causes, and can quickly fix things DIY-style. It is ...

Back in the 1980s, it was common for your average family sedans to produce less than 150 horsepower from internal combustion engines that weren’t all that small. I still can’t believe we drove ...
