One important factor in rating any car is fuel economy. As fuel prices rise across the nation, the last thing you want is for your car to be gobbling any more fuel than is necessary. As a general rule, then, it’s important to ensure that the elements of your car that impact fuel economy are in good repair. One such component is the engine knock sensor, which is partially responsible for ensuring that the engine and fuel delivery systems are timed properly and that the fuel/air mixture being sent to the engine is correct. The job of the sensor is to prevent fuel from detonating in the cylinder rather than burning quickly. A good sensor will improve your fuel economy by ensuring that fuel in your engine cylinders is used properly – while a bad sensor will cripple your fuel economy by allowing your engine to work in a way that is rather detrimental to overall function and economy. To keep your vehicle’s fuel economy high, take care that you use the best parts for your repairs and maintenance. A great place to find the parts you need is online at PartsGeek.com, where you’ll be able to access a great selection of parts at unbeatable prices.
