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 ...

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 ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.

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 ...

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.

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 ...

Port fuel injection and direct injection are similar but distinct systems, so why do some engine designs include both?

Yes. Because the fuel/air mix is directly injected, it does not enter the combustion chamber via the inlet valves and does not clean them. As a result, carbon can accumulate on the inlet valves.

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

The Korean manufacturer Kia has announced that it has developed a new gasoline direct injection (GDI) engine. The new power unit is a largish (2.4 litre) four-cylinder engine which produces about 200 ...

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 ...

Volvo is set to introduce an all-new four-cylinder engine to its range next year in the form of its GTDi (Gasoline Turbocharged Direct Injection) 2.0-litre unit that will feature in the brand's S80, ...
