Description
Product Overview
The 4802820ND speed sensor is installed in the engine block. The metal probe senses the crankshaft signal ring and transmits speed and phase data to the electronic control unit, thereby precisely controlling the fuel injection timing and fuel quantity. The old sensor is prone to failure in signal sensing, aging and leakage of the sealing ring, and poor contact of the plug, resulting in weak starting, power interruption, etc. Replacing this sensor can restore stable fuel injection control of the engine. It is suitable for maintenance and replacement of light trucks, small construction machinery, and agricultural diesel vehicles.
Unique Core Features of the Single Product
Solid stainless steel front-mounted sensing probe, stable signal interference resistance
Front integrated metal sensing cylinder, sensitive magnetic field conduction, can shield electromagnetic interference in the engine compartment and high-temperature interference, no signal loss or drift in high and low speed ranges, avoiding sudden loss of fuel and engine shutdown during driving.
Single-channel thickened brown ring-shaped sealing gasket, prevents oil and water leakage
A one-piece oil-resistant rubber sealing ring is configured in the middle of the probe, filled the installation gap of the engine body after assembly, blocking the entry of engine oil and water vapor into the internal sensing chip, preventing the sensor from getting damp and short-circuiting and failing.
Side-opening snap-on waterproof plug, not likely to loosen in bumpy conditions
The black plastic sealing interface on the rear side has an internal fully sealed dustproof and waterproof structure. The pins are less likely to oxidize and loosen under long-term vehicle vibration and oil contamination in the engine compartment, ensuring stable transmission of speed signals throughout the year.
Positioning and limit step structure, adjustable assembly depth without damaging the probe
The limit step structure between the probe and the housing automatically limits the insertion depth when拧入 the engine body, preventing the probe from pressing the gear ring and causing scratches and wear， extending the service life of the sensor.
Integrated plastic shell for high and low temperature resistance， suitable for complex outdoor conditions
The shell is made of high-temperature resistant modified engineering plastic， and the metal probe is treated with passivation and rust prevention. It is less likely to crack or rust in low-temperature and high-temperature environments in the engine compartment， maintaining stable signal collection accuracy throughout the year. Applicable scenarios
Light-duty diesel freight vehicles, small excavators, agricultural tractors, mobile diesel generators, suitable for urban roads, field construction sites with alternating high and low temperatures, and dusty light-load operation equipment.
