How Gasoline Direct Injection causes Chain Wear, Fuel Dilution, and LSPI. One of the biggest changes to gasoline combustion ...

Better fuel economy and lower emissions from gasoline direct-injection engines are getting closer. Most European automakers are preparing GDI engines for introduction in the next few years, starting ...

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 ...

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 ...

SAE Transactions, Vol. 107, Section 3: JOURNAL OF ENGINES (1998), pp. 2172-2182 (11 pages) Direct Injection technology represents a major breakthrough for both, Gasoline and Diesel engines with ...

Direct injection systems, in which a high-pressure fuel pump pressurizes the fuel for injection directly into the cylinder by an injector, provide greater freedom in the injection timing and volume ...

Isuzu Motors (Japan) announced Friday that it is partnering with Canadian company Westport Innovations to develop engines using Westport’s Compressed Natural Gas Direct Injection (CNG-DI) technology.

Ford of Europe will install gasoline direct-injection, spark-ignition engines into some of its smaller vehicles beginning in 2003. Called Duratec SCi - for Smart Charge injection - the engines feature ...

Full-load operation of a small-displacement sparkignition direct-injection (SIDI) engine was thoroughly investigated by means of computational analysis and engine measurements. The performance is ...
