Volvo Knock Sensor

With the fast and continuous advances in technology, the automotive field included, many will actually find it hard to comprehend a lot of the new innovations introduced. Before people can actually come into terms and understand the present technology, there will be another new one offered that promises much more power and greater ride quality. Drivers and auto owners have nothing to do but embrace these new developments as they come since they indeed make driving more pleasant, safer, and easier. Modern vehicles with new and improved technologies now have the knock sensors. ‘Knock’ is the sound that your Volvo engine gives off when part of the fuel and air mixture in one or more of the cylinders ignite spontaneously due to compression, independent of the combustion that is started by the spark plug, and resulting to an explosion instead of the usual controlled burn.

The Volvo knock sensor will automatically detect the knocking sounds or the detonation and then automatically retard the spark to compensate. And then technically, in the process of retarding the spark, there will be delays. These delays will allow maximum gasoline expansion to occur when the piston is more in its down stroke within the cylinder head. This will then result to the reduction of the cylinder pressure, thereby eliminating detonation. Your Volvo knock sensor is usually located in the engine block, cylinder head, or the intake manifold, and is tuned to detect that frequency.

The knock sensor in general plays an important role. This particular part listens to the engine. The moment it hears engine knock, it then sends a signal to the Engine Control Unit. The ECU will in turn delay and retard your vehicle’s engine advance. This will stop the engine knock and decrease the engine power. By installing the knock sensor in your Volvo, the computerized engine control system will allow the engine to operate very near its detonation limit, thus improving power and efficiency.

From the looks of it, you can generally say that the Volvo knock sensor is a cost-effective way to have a pleasant ride while ensuring the long life of your vehicle’s engine. Having the knock sensor installed in your Volvo is actually a very good investment for you. So why not arm your vehicle with a Volvo knock sensor by shopping here at Parts Train?
