How did fuel injection change the throttle body?
Fuel injection systems have since then grown into finely tuned, electronically controlled and operated machines that have improved engine fuel burning efficiency by as much as 70% over the past three decades. The throttle body hasn’t changed much in mechanical design or in function since the early mechanical fuel injection systems were in use.
Where is the throttle cable on a fuel injected engine?
On older vehicles, the throttle body of a fuel injected engine is operated by a throttle cable that is either attached to the gas pedal or to an electronic throttle control. The reason you need to consider this fact first is because electronic throttle bodies are calibrated with incredibly tight clearance on the throttle blades.
What happens to the engine when the throttle body is dirty?
When the throttle body is dirty, it lowers the engine RPM band, causing the engine to stumble and delay the time that the vehicle is supposed to shift into a higher gear. The engine idle is rough: Typically a dirty throttle body also impacts the way the engine idles.
What do you remove from a throttle body?
Step 2: Remove the air filter cover, mass air flow sensor, and intake tube. Remove the clips holding the air filter housing onto the base. Remove the connection or clips securing the mass air flow sensor to the lower intake hose. Step 3: Remove the air intake hose from the throttle body.
Where is the throttle body in the engine?
A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal.
What did throttle bodies do in the 1980’s?
Back in the 1980’s Detroit’s auto manufacturers were transforming all there engine platforms to direct port fuel injection which included an entire array of new components such as fuel injectors, air intakes, mass air sensors and throttle bodies.
Where does the BBK Performance throttle body come from?
As has been the case since our first units back in the eighties, each BBK “Power Plus Series” performance throttle body is designed & produced in the USA using a new fully CNC machined 356 aluminum alloy housing assembled with an array of the highest quality components for great drivability and maximum performance.
How big is the throttle body on a Dodge Charger?
On some models such as the Dodge Challenger & Charger where they went from a 6.1L Hemi to a 6.4L but kept the same size factory throttle body, the bigger of the two BBK offerings makes the most sense. Are BBK Throttle Bodies emissions legal?
