Chances are your contact with your car’s fuel is limited to filling it up at the gas station. But, once you put in that fuel it has quite a journey and a few important responsibilities. Your car’s fuel management system must: Allow the engine to start and run in the coldest and hottest places; Allow the engine to run smoothly under all conditions; And keep exhaust emissions in check. The vehicle’s fuel management system uses a multitude of sensors to gather information such as temperature, pressure, air flow, and other parameters.
This information is processed by engine control module. The engine control module can then operate the fuel injectors and various other actuators that control the engine operation. Key components of the fuel management system include: – Fuel Pump – Fuel Filter – Fuel Pressure Regulator – Fuel Injectors – Airflow Sensor – Engine Coolant Temperature Sensor – Oxygen Sensors – Throttle Body – Engine Control Module The fuel management system’s various components may malfunction, this can cause a no-start condition, or you could experience a loss of power, fuel economy or other driveability concern. This can also be accompanied by an illuminated or flashing check engine light, which is nothing to ignore. Have a look at today’s video for a little more insight into your fuel management system.
However, they’re another important part of your car that keeps your ride smooth and safe, and they need proper maintenance. Wheel bearings are what enable your wheels to spin freely. Since they bear the entire weight of the vehicle, they have to be tough. Wheel bearings can last well over 100,000 miles, but they do wear out and eventually need to be replaced.
Your power brake system helps you provide braking power, so you don’t have to do all the work with your brake pedal. So what’s involved in the power brake system? The actual brakes are applied at the wheel, using hydraulic pressure. When you step on the brake pedal, it creates pressure in the power booster that’s multiplied by vacuum from the engine, and the resulting pressure pushes brake fluid through the master cylinder, into tubes and hoses that run to the brake at each wheel.
