Don’t Knock The Humble Knock Sensor – Piezoelectric Knock Sensors – Design, Theory And Operation

Don't Knock The Humble Knock Sensor - Piezoelectric Knock Sensors - Design, Theory And Operation Knock Sensor - Waveform What They Are This is a quick technical dissertation will cover the design, function and how to test piezoelectric knock sensors on gasoline engine equipped vehicles. Often buried deep down in the bowels of the engine, the knock sensor is one of those things that rarely fails, or is even discussed, until a problem occurs. To put it simply, knock sensors are vibration sensors that are well suited to detect structure-borne acoustic oscillations. Purpose  This can occur as knock in a gasoline [...]

Unhappy Kitty – Jaguar Check Engine Light On – Bringing Back The Purr!

The Unhappy Kitty - Jaguar Check Engine Light On This is a great study of dedication, and a solid illustration that logical thinking, some "detective work", and understanding of how automotive systems actually work, make all the difference in service outcomes. In other words, "knowing", rather than just "parts changing". It's also a cautionary tale that "scanning the computer" and use of fault codes, does not fix cars, it may or may not give an indication of the area in which to investigate, but unless there is true knowledge of how the system operates, it can lead to unnecessary work and parts replacement. [...]
