1. The fuel mixture is automatically altitude-controlled by the automatic mixture control . 2. The fuel mixture is manually controlled by a fuel mixture control lever in the cockpit. 3. The engines have automatic mixture adjustment, so there is no mixture control required on the panel. 4. Closed-loop fuel injection systems improved the air fuel mixture control with an exhaust gas oxygen sensor. 5. The pintle injector permits good mixture control of fuel and oxidizer over a wide range of flow rates. 6. The plate covers or uncovers the fuel metering jets as the mixture control lever is moved as follows: 7. These may include remote mixture control allowing the driver to optimise the fuel / air mixture during a race. 8. If this is done via the intake system, the mixture is, in effect, enriched, creating a mixture control and pollution issue. 9. The controls at the left the instrument include keyboard splits and mixtures of the two instruments, as well as normal Clavinet mixture controls . 10. The cockpit lever has either three or four detent positions that causes a cloverleaf shaped plate to rotate in the mixture control chamber.
