| 摘要： | The carburetors of years past did a tremendous job of propelling down the road the heavy steel beasts we used to call automobiles (Figure 1). For decades, it was the fuel delivery method used for gasoline-powered engines by most automobiles, recreational vehicles, and power equipment. The carburetor still does a fantastic job of accomplishing that goal. Proof of that is its wide use in racing circuits around the world even today. However, if power output were the only goal, we likely would not have realized the birth of the computerized fuel injection systems we've come to know over the past four decades or so.A properly tuned carburetor did a fantastic job of keeping our gasoline internal combustion engines running strong and fuel-efficient. To accomplish this task, these purely mechanical devices relied on pressure differential as the incoming air from the atmosphere passed the carburetor's jets. Designed as Venturis, these jets would spill liquid fuel into the passing airstream, which would help to atomize the liquid fuel. As the air/fuel charge made its way through the intake runners of the manifold and into the intake valve ports, the now-homogenized mixture would enter the combustion chambers and lie in wait for the ignition event to initiate the combustion process. |
