Fuel and air metering auxiliary emission control refers to systems and components in a vehicle's engine management that regulate the mixture of fuel and air entering the combustion chamber. These controls are designed to optimize combustion efficiency, reduce harmful emissions, and ensure compliance with environmental regulations. By adjusting factors such as fuel injection timing and air intake, these systems help minimize pollutants like nitrogen oxides and unburned hydrocarbons. Overall, they play a crucial role in enhancing engine performance while meeting stringent emission standards.
The Volvo S70's "Malfunction Control Fuel and Air Metering Auxiliary Emission Control" warning typically indicates an issue with the vehicle's fuel delivery system, air intake, or emissions control components. Common causes may include a malfunctioning mass air flow sensor, fuel injectors, or exhaust gas recirculation (EGR) system. It's advisable to have the vehicle diagnosed using an OBD-II scanner to identify specific trouble codes, which can help pinpoint the exact problem. Regular maintenance and timely repairs can help resolve these issues and ensure optimal performance.
P1131 - Manufacturer control fuel air metering - Swirl Control
Metering the air/fuel mixture always looking for that "sweet spot", 14.7 to 1.
Manufacturer control fuel air metering refers to a system in which the manufacturer regulates the mixture of fuel and air supplied to an engine or combustion process. This control ensures optimal combustion efficiency, performance, and emissions by precisely managing the ratio of fuel to air based on operating conditions. It typically involves advanced technologies, such as electronic fuel injection or sensors, to adapt to varying conditions and improve overall engine performance.
You must be talking about a CARBURETOR. They are called metering rods. They control how much fuel flows through the jets in the carburetor as you push the gas pedal. They can make a engine run lean or rich, by changing the air/fuel ratio.
DTC P0255: Injection Pump Fuel Metering Control "A" Intermittent (Cam/Rotor/Injection).....
The manufacturer was able to meet the tail pipe emission requirement without EGR through timing and fuel control.The manufacturer was able to meet the tail pipe emission requirement without EGR through timing and fuel control.
You may be talking about the fuel vent. The evaporation emission control valve. If so, it is on the line running out of the fuel tank.
The Evaporative Emission Control System(EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system.
Trouble code P0443 means:Evaporative emission control systempurge control valve circuit malfunction
do not remove the emission control. you need that for fuel economy and does NOT effect performance. at wide open throttle the emissions control - o2 sensors, are not used it goes into open loop and the egr is closed. catalytic converters do not restrict the exhaust.
