Gasoline Direct Injection

Gasoline Direct Injection

In internal combustion engines, Gasoline Direct Injection(GDI), also known as Petrol Direct Injection or Direct Petrol Injection or Spark Ignited Direct Injection(SIDI) or Fuel Stratified Injection(FSI), is a variant of fuel injection employed in modern two-stroke and four-stroke gasoline engines. The gasoline is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port.

In some applications, gasoline direct injection enables a stratified fuel charge (ultra lean burn) combustion for improved fuel efficiency, and reduced emission levels at low load.

Famous quotes containing the words gasoline and/or direct:

    I love the smell of napalm in the morning. You know, one time we had to hailbomb, for twelve hours, and when it was all over I walked up.... We didn’t find one of ‘em, not one stinking dink
    body. That smell, you know, that gasoline smell. The whole hill. It smelled like ... victory.
    John Milius, U.S. screenwriter, Francis Ford Coppola (b. 1939)

    I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact.... There is wanting constant and accurate observation with enough of theory to direct and discipline it. But, above all, there is wanting genius.
    Henry David Thoreau (1817–1862)
