Ford Focus-ed on reducing CO2

You've got to hand it to today's automotive engineers. They are absolute magicians at getting new models to emit less CO2. One of the newest -- and coolest -- developments is on the third-generation Ford Focus.

The compact car's Active Grille Shutter, which is standard in Europe, improves aerodynamics by using vents to control airflow through the grille to the cooling system and engine compartment.

If the car needs air to cool the engine, the vents are automatically opened. If no airflow is needed, the vents are shut, which reduces aerodynamic drag and in turn cuts CO2 emissions by 2 percent, Ford says, or about a gram of CO2 per kilometer depending on the powertrain.

Ford says it is discussing whether to make the Active Grille Shutter standard in Russia and China.

Its development shows the lengths automakers are going to save every single gram of CO2 possible.

What causes the Evap system s to fail?

What causes the Evap systems to fail? Is this type of repair expensive? I assume I should have some one reset the check engine lite to verify that there is a problem right?

Answer:

1) What causes the Evap system s to fail? : Age , poor manufacturing, same stuff as when the vacuum sweeper fails. yes , before you ask there is a bag that can get clogged, it is more like a box though and is called a charcoal canister. The canisters job is to collect gas fumes. 2) Is this type of repair expensive? : Depends on the failure. If you just left your cap loose once and it set the light, or you need to replace the cap... I would say NO, not to expensive. Did you run over something and bust the Evap control unit, then yes I would say its gonna be expensive. 3) I assume I should have some one reset the check engine lite to verify that there is a problem right? : I think having the light reset is a wonderful Idea. And if it returns then you will know for certain. And no, you do not Have to do it if you don't want to . The vehicle will run just fine with the light on as far as the EVAP system is concerned.

I need auto repair manual information for a canister purge valve

I have a 1995 Ford F-150 302 V-8 and need auto repair manual information for the canister purge valve, canister purge valve failure Response: COMPONENT TESTING Fig. 1: A manifold vacuum gauge can be used to check the evaporative canister components

Canister Purge Regulator Valve 1) Disconnect the hoses at the purge regulator valve. Disconnect the electrical lead. 2) Connect a vacuum pump to the vacuum source port. 3) Apply 5 in. Hg (16.9 kPa) to the port. The valve should hold the vacuum. If not, replace it. Canister Purge Valve Apply vacuum to port A. The valve should hold vacuum. If not, replace it. Apply vacuum to port B. Valves E5VE–AA, E4VE–AA and E77E–AA should show a slight vacuum leak-down. All other valves should hold vacuum. If the valve doesn't operate properly, replace it. Apply 16 in. Hg (54 kPa) to port A and apply vacuum to port B. Air should pass. On valves E5VE–AA, E4VE–AA and E77E–AA, the flow should be greater than that noted in Step 2. NOTE: Never apply vacuum to port C. Doing so will damage the valve. If the valve fails to perform properly in any of these tests, replace it. REMOVAL & INSTALLATION Carbon Canister Fig. 1: Remove the hoses, then unscrew the canister from its mounting Disconnect the negative battery cable. Label and disconnect the vapor hoses from the carbon canister. Remove the canister attaching screws and remove the canister. Installation is the reverse of the removal procedure. Fuel Tank Vapor Orifice and Rollover Valve Assembly Disconnect the negative battery cable. Remove the fuel tank as described in Section 5. Remove the vapor orifice and rollover valve assembly from the fuel tank. Installation is the reverse of the removal procedure. Purge Control Valve Disconnect the negative battery cable. Label and disconnect the hoses from the purge control valve. Remove the purge control valve. Installation is the reverse of the removal procedure. Purge Solenoid Valve Disconnect the negative battery cable. Label and disconnect the hoses from the purge solenoid valve. Disconnect the electrical connector from the valve. Remove the purge solenoid valve. Installation is the reverse of the removal procedure. Fuel Bowl Solenoid Vent Valve Disconnect the negative battery cable. Label and disconnect the hoses from the fuel bowl solenoid vent valve. Disconnect the electrical connector from the valve. Remove the fuel bowl solenoid vent valve. Installation is the reverse of the removal procedure. Fuel Bowl Thermal Vent Valve Disconnect the negative battery cable. Label and disconnect the hoses from the fuel bowl thermal vent valve. Remove the fuel bowl thermal vent valve. Installation is the reverse of the removal procedure. Pressure/Vacuum Relief Fuel Cap Unscrew the fuel filler cap. The cap has a pre-vent feature that allows the tank to vent for the first 3⁄4 turn before unthreading. Remove the screw retaining the fuel cap tether and remove the fuel cap. Installation is the reverse of the removal procedure. When installing the cap, continue to turn clockwise until the ratchet mechanism gives off 3 or more loud clicks.
