A knock sensor is important to a car's fuel efficiency. It helps the car balance its timing and fuel-to-air mix, which optimizes the amount of power to the engine.
Knock sensors also protect car parts from the damaging effects of engine knock. When a knock sensor is bad, it can't regulate the engine properly. The car vibrates and it sounds like there is something banging up against the car's cylinder. The knocking action can destroy the pistons, rods, valves, gaskets and plugs.
Knock sensors are designed to convert vibration into electric signals to enable the electronic control unit (ECU) to detect knocking combustion and retard the ignition point to prevent damage to the engine. Bosch sensors have proven themselves under tough conditions in millions of passenger vehicles and can also be found in industrial applications. Bosch offers the perfect solution for almost every requirement of the motor-vehicle segment. Precision, reliability, and a long service life are the key features of all Bosch sensors. They deliver first-class quality to meet the highest standards of the automotive industry.
Knock sensors and oxygen sensors, or O2 sensors, function as sensing devices that detect variations in an automotive engine's performance. Knock sensors...
