 The car battery stores the electrical energy necessary to start the ignition and keep the car running. Naturally, you want to avoid getting stuck by a dead battery, so there are many steps you can take to keep your battery in good working order. Clean the battery regularly, tighten the hold-down, use insulation to protect it from the cold, and maintain its fluid levels. To maintain the charge, drive the car often and unplug any appliances when the car isn't running. With good care, your battery can last 5 to 7 years. 1.Clean the battery terminals with water andbaking . First, identify the positive side of the battery by finding the red cap. Always disconnect the negative side first. Turn the bolt connecting the wires to the negative terminal counterclockwise and lift the wire up. Do the same for the positive side, making sure you don't touch the 2 wires to any metal parts of the car. Then make a 1:1 mixture of baking soda and water. Dip a hard-bristle brush into the solution a

  The Exhaust Gas Recirculation (EGR) system is sometimes misunderstood as to its function and purpose. In many countries around the world, the emissions of Nitrogen oxide (NOx) from diesel and gasoline vehicles are restricted by legislation. EGR is an effective technical solution to control NOx values. The principle of EGR is to work as a controllable proportion of the exhaust gas is recirculated back into the engine. EGR The EGR is used as one of the key components in reducing exhaust gas emissions and pollutants into the atmosphere. Since the introduction of Euro 6 regulations with a reduction of 55% in nitrogen oxides from Euro 5. Between Euro 5 and Euro 6 regulations on diesel engines the drop in Nitrous Oxide (NOx) is from 180mg per driven kilometre to 80mg per driven kilometre The higher the exhaust gas temperature (over 1800°C), the higher the amount of nitrogen oxides! The EGR is designed to recirculate exhaust gas back in the inlet manifold, by doing so this can lower the exh

    Evaporative Emission Control (EVAP) If you’ve ever left the gas cap loose on a modern car, there’s a good chance you’ve had an encounter with the evaporative emission control (EVAP) system. The EVAP system traps smog-forming fuel vapors and prevents them from entering the atmosphere. When there’s a problem⁠—such as a leaking gas cap⁠—somewhere in the system, your car’s primary computer (often referred to as the powertrain control module) will turn on  the check engine light . At the same time, the module stores an EVAP-related  diagnostic trouble code (DTC)  in its memory. If EVAP system problems didn’t trigger the check engine light, you might not realize the system was there. An EVAP malfunction rarely affects vehicle performance (unless the purge valve is leaking) or driver comfort in any way. But that doesn’t mean you should ignore a problem with the EVAP system; on the contrary, an EVAP failure is almost guaranteed to prevent your car from passing a state emissions test. What’
