EcoBoost Gasoline Direct Injection

performance capability and efficiency of the
EcoBoost engines
• Fuelisinjecteddirectlyintothecombustionchamber
of each cylinder by solenoid-controlled high-pressure
injectors, compared to traditional fuel injection
where fuel is mixed with intake air prior to entering
the chamber
– Fuel is pumped from the tank at a normal pressure
of around 200 psi to the engine compartment
– A cam-driven high-pressure fuel pump increases
fuel pressure to around 2150 psi, depending on the
demands of the engine

ENGINEERING INSIGHT
EcoBoost Turbocharger
What It Is
• Aturbochargerusesotherwisewastedenergyfrom
theengine’sexhausttorotateaturbinewheel
How It Works
• Theturbinewheeliscoupledtoacompressorthat
pressurizesaircomingintotheengine—thisis
called “boost” and allows the engine to breathe in
air as if it were larger in displacement since more
air is “forced” into the intake
