Your vehicle's engine needs clean air to burn the fuel – and it needs a lot of clean air. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Craig Johnson Automotive in Rowland Heights, we ensure you get the best air quality in your vehicle and explain the process of where this dirty air is going to our area drivers. 

Your car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.

What does it do? - The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.

Without a working battery, your car will not be able to start. If you perform proper maintenance, however, an average car battery can start your car reliably for roughly four years. Your vehicle's radio and headlights, plus a slew of other important functions, are powered by an electrical current generated by your vehicle’s engine but a vital part of generating electricity is having a place to store it while it’s not being used, which is where a car battery comes into play. The battery holds electrical energy while a car is off in order to help the engine turn over and create a spark to start internal combustion.  What you don't want is to have a bad battery!!
