An electrical device called a crank sensor is used in internal combustion engines—both gasoline and diesel ones—to track the crankshaft’s position or rate of rotation. Engine management systems employ this data to regulate the timing of the ignition system, fuel injection, and other engine characteristics.
Prior to the development of electronic crank sensors, petrol engines required the distributor to be manually adjusted to a timing mark.
The interaction between the pistons and valves in the engine can be monitored using the crank sensor in conjunction with a camshaft position sensor that is comparable, which is crucial in engines with variable valve timing. The multipurpose sensor used to control ignition timing, gauge engine RPM, and gauge relative engine speed is the crankshaft position sensor.
With this sensor, manual distributor timing is unnecessary. The crankshaft position sensor’s functional goal is to ascertain the crank’s location and/or rotational speed (RPM). Engine Control Units employ the data the sensor transmits to regulate variables like fuel injection time and ignition timing. The sensor will manage the fuel injection in a diesel.
The current combustion cycle can be determined from the sensor output and other sensor data, such as the cam position; this is crucial for a four-stroke engine’s starting.
The sensor may occasionally burn out, become worn out, or simply pass away at a high mileage. Exposure to intense heat is a likely factor in crankshaft position sensor failure.
The global Crankshaft speed sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Ten Camshaft and Crankshaft speed Sensors have been introduced by DENSO, ensuring that the Toyota and Lexus cars in the European car pool can now take advantage of DENSO OE technology.
The sensors feed data to the vehicle’s ECU, which regulates ignition and injection timing. The engine stalls or can even be unable to start in the event of sensor failure.
The eight new DENSO Camshaft Position Sensors have numerous applications across the same vehicle pool, whilst the five new DENSO Crankshaft Position Sensors have specific applications across the Toyota and Lexus range, both past and present.
The small and delicate camshaft and crankshaft position sensors not only offer a highly reliable original equipment (OE) solution to common automotive problems, but also aid in achieving the goals of cleaner vehicle emissions and greater fuel economy (reduced CO2 emissions).
