Subaru Knock Sensor

Having the right and high performance engine parts equipped in your vehicle will surely provide you that driving satisfaction and maximum engine functionalities you’ve always wanted. If you own one of the top vehicles makes like the Subaru, surely you will need to equip it with parts and components that will make it perform at its highest peak level such as the Subaru Knock Sensor. This guarantees an exact fitment and efficiency that will compliment the specifications of your vehicle. Although there are a lot of available knock sensor parts in the market that can be installed in your vehicle, still the best way to unleash your engine’s power is by getting it operational with parts that offers an ideal match for proper engine performance.

The Subaru Knock Sensor is an essential device that plays a vital role in proper engine functions. It generates a voltage that can detect a possible knock in your engine. If a knock is detected, it transmits a signal to the electronic engine management control unit triggering a process control in your engine that will manage and eliminate the knock. The ECM works by using the knock sensor signal to control the timing and fuel injection. An engine knock happens within a specific frequency range that is why the knock sensor is mounted in the engine block, cylinder head, or intake manifold to effectively and easily determine that frequency. Inside the knock sensor is a piezoelectric element that is the one actually responsible for producing the voltage when pressure or vibration is incurred to them. This element is tuned to the engine knock frequency.

A knock in the engine occurs due to the high pressure and temperature in the cylinder during the internal combustion wherein the unburned fuel and air mixture are spontaneously ignited. To prevent this from happening, the temperature level and pressure must be maintained at a tolerable level. Other factors that can cause an engine knock are the engine compression ratio and pre-ignition. The engine compression ratio must always be at a manageable level. If the air and fuel mixture are compressed more, a higher pressure is generated and would tolerate a knock. That is why proper mixture compression is required to avoid the occurrence of a knock. Pre-ignition triggers an increase in spark advance and has the same effect where a knock would most likely to happen. So all these factors must be carefully considered to prevent an engine knock and also equipping your vehicle with a fully functional and highly reliable knock sensor will surely provide you that peace of mind.

The Subaru Knock Sensor is designed to accurately detect an engine knock as well as providing a full balance and function to your vehicle. With its ability to monitor proper engine combustion process and an effective air-fuel mixture, an efficient fuel burning at the right timing is achieved. This can result to an impressive increase in engine power and performance and better fuel mileage. It is expected that this knock sensor will highly function all throughout its lifespan. But over time, its normal wear can show and would require you to get a replacement. Proper maintenance can greatly prolong its life and functionality so it is best to have it inspected periodically. A knock sensor in a poor working condition can damage your engine and would lead to a more serious damage to other engine components and would surely cost you a lot of money.
