Buick Knock Sensor protects your engine by knocking the damaging engine parts before they can break. Buick was born in 1903 and has been over a century of its life in pursuit of a twin goal of seeking a relaxing, cushy ride without losing the steering wheel feel. The Buick cabin isolates the road noise by setting the tuning to quiet, but not muting enough to give the drivers the sense that they are still in control. The fact that it can combine comfort and a bit of theater is demonstrated by convertible tricks such as the slick folding roof on its drop-tops. By launching Wildcat EV concept, it sent a message that was understandable: modern looks and electric punch will be on the same family tree with the old straight-eight sedans. The long drives are less exhausting as the seats are soft and steering is predictable. The layout of digital dashboard design maintains simplicity of buttons and minimal distractions in order to have a quick glance. Within that broader series of features, the Knock Sensor is fitted deep in the block, piezoelectric guts that hear the sharp pressure spike, which indicates detonation and then shoots a voltage out to trigger the control module to snatch timing and pull the pistons away. The speed of its response in microseconds reduces the octane requirement, maintains boost faithful and extends engine life when the driver is crawling through traffic or busting a ramp. A healthy Knock Sensor will thus be a compromise of possible engine knock in favor of solid daily reliability throughout the entire catalog.
