Product Description

Precision - Engineered for Unmatched Performance

The Engine Crankshaft Position Speed Sensor, identified by part numbers 5594275, 2872277, 4921684, 5594276, 2872279, and 5491326 (along with their alternative part numbers [List here if available]), is a crucial component in Cummins engines, especially those used in excavators and a wide range of other applications. This sensor plays a pivotal role in the engine's operation by accurately measuring the position and speed of the crankshaft. The data it provides is essential for the engine control module (ECM) to manage ignition timing, fuel injection, and overall engine performance.

Product Name	Engine Crankshaft Position Speed Sensor
Main Part Numbers	5594275, 2872277, 4921684, 5594276, 2872279, 5491326

As the crankshaft - attached ferromagnetic target wheel rotates, its teeth change the magnetic field around the sensor's coil, inducing an AC voltage. The ECM analyzes this voltage's frequency and amplitude to determine crankshaft position and speed.
Technical Specifications	- Operating Voltage: 9 - 16V DC - Frequency Response: Up to 10,000 RPM - Measurement Accuracy: ±0.5° - Operating Temperature: - 40°C to 125°C
Compatible Engine Models	- Excavator - specific: QSB Series, QSC Series - Others: ISB 5.9L/6.7L, ISX/QSX Series, B Series 3.3L
Core Advantages	- High - precision measurement for accurate ignition and fuel injection - Strong environmental adaptability (vibration - resistant, dust - proof, temperature - tolerant) - OEM fit for easy installation - Warranty and technical support provided
Application Scenarios	Excavators, trucks, industrial equipment, power generation units, etc.
Maintenance Tips	Check the sensor when symptoms like engine misfires, poor acceleration, increased fuel consumption, or dashboard warning lights occur. Replace with genuine Cummins parts and calibrate after installation.

Function and Working Principle

The sensor operates based on the principle of electromagnetic induction. It consists of a permanent magnet, a coil, and a ferromagnetic target wheel attached to the crankshaft. As the crankshaft rotates, the teeth of the target wheel pass by the sensor, causing a change in the magnetic field around the coil. This change induces an alternating current (AC) voltage in the coil. The frequency and amplitude of this voltage are directly related to the speed and position of the crankshaft. The ECM then analyzes this electrical signal to determine the exact position of the crankshaft at any given moment, which is vital for precise engine control.

Benefits of Using Genuine Cummins Sensors

QSB Series: In Cummins QSB engines commonly used in small to medium - sized excavators, the 5594275, 2872277, 4921684, 5594276, 2872279, 5491326 sensors are essential for maintaining optimal engine performance. These engines power excavators that are used for various tasks such as trenching, grading, and material handling. The accurate speed and position data provided by the sensor allow the engine to adjust power output according to the load on the excavator's hydraulic system, resulting in efficient fuel consumption and smooth operation.
QSC Series: For larger excavators equipped with QSC engines, these sensors play a critical role. QSC engines are known for their high - torque output, which is required for heavy - duty digging and lifting operations. The sensor ensures that the engine's power delivery is precisely controlled, preventing engine stalls during sudden heavy loads and optimizing the performance of the excavator's hydraulic pumps.

ISB 5.9L and 6.7L: These engines are widely used in a variety of applications, including trucks and some industrial equipment. The crankshaft position speed sensor is crucial for maintaining proper engine timing in these engines. In trucks, it helps in achieving smooth acceleration and deceleration, while in industrial equipment, it ensures consistent power output during continuous operation

ISX and QSX Series: Found in heavy - duty trucks, buses, and large - scale industrial power generation units, the ISX and QSX series engines rely on these sensors for accurate engine control. The sensors enable the engines to meet strict emission standards by providing precise data for the ECM to adjust fuel injection and ignition timing, resulting in efficient combustion and reduced pollutant emissions.

B Series 3.3L: In smaller vehicles and equipment powered by the B Series 3.3L engines, the sensor ensures that the engine runs smoothly. It helps in optimizing fuel consumption and preventing engine misfires, which is especially important for applications where fuel efficiency is a key consideration.

Reliability: Genuine Cummins sensors, such as those with part numbers 5594275, 2872277, 4921684, 5594276, 2872279, 5491326, are designed and manufactured to the highest quality standards. They are built to withstand the rigorous operating conditions of Cummins engines, ensuring long - term reliability. This reduces the risk of sensor failure, which could otherwise lead to engine malfunctions, unexpected breakdowns, and costly repairs.

Precision Performance: These sensors offer precise measurement capabilities, providing the ECM with accurate data about the crankshaft's position and speed. This precision allows the engine to operate at its optimal performance level, resulting in better fuel economy, increased power output, and reduced emissions. For example, in an excavator, precise engine control can lead to more efficient digging operations, saving both time and fuel.

Direct Fit and Easy Installation: Cummins sensors are designed to be a direct fit for the specified engine models. This means that they can be easily installed without the need for modifications, reducing installation time and the risk of incorrect installation. Proper installation is crucial for the sensor to function correctly and for the engine to operate efficiently.

Warranty and Support: When you purchase a genuine Cummins sensor, you can expect a manufacturer's warranty. This provides peace of mind, knowing that if the sensor fails within the warranty period, it can be replaced or repaired at no additional cost. Additionally, Cummins offers extensive technical support, ensuring that customers have access to the information and assistance they need for proper sensor installation and maintenance.

Technical Specifications

Operating Voltage: The sensor is designed to operate within a voltage range of 9 - 16 volts DC, ensuring compatibility with the electrical systems of Cummins engines. This wide voltage tolerance allows it to function reliably even in situations where the vehicle's electrical system may experience minor fluctuations.

Frequency Response: It has an excellent frequency response, capable of accurately detecting changes in crankshaft speed up to 10,000 revolutions per minute (RPM). This high - speed detection ability is crucial for engines that operate at varying speeds, such as those in excavators during different digging and loading operations.

Measurement Accuracy: The sensor offers a high - level of measurement accuracy, with a position resolution of ±0.5 degrees. This precision ensures that the ECM receives highly accurate data about the crankshaft's position, enabling it to make precise adjustments to the engine's ignition and fuel injection systems.

Environmental Resistance: Constructed with high - quality materials, the sensor is highly resistant to environmental factors. It can withstand temperatures ranging from - 40°C to 125°C, making it suitable for use in extreme weather conditions. Additionally, it is protected against moisture, dust, and vibrations, ensuring reliable operation in the harsh environments typical of construction sites where excavators are used.
