Product Details
1. Basic Overview & Core Functional Positioning
The E4G16-1006040BC Intake Camshaft Phaser is a genuine Original Equipment Manufacturer (OEM) component exclusively developed and produced by Chery Automobile Group, specifically tailored for the Chery Jetour X70 mid-size SUV—a model renowned for its spacious interior, reliable performance, and adaptability to both urban commuting and long-distance travel. As a critical precision component in the vehicle’s engine valve timing system, this intake camshaft phaser (hereinafter referred to as "the phaser") is mounted at the front end of the intake camshaft in the Jetour X70’s E4G16 1.6L naturally aspirated engine, working in tandem with the engine control unit (ECU), timing system, and valve train. It serves as a core "timing regulator" that dynamically adjusts the intake camshaft’s phase angle, optimizing the engine’s intake timing according to real-time operating conditions—directly influencing the engine’s power output, fuel efficiency, and exhaust emissions.
Unlike fixed camshaft timing systems that operate at a single, pre-set phase angle, the E4G16-1006040BC Intake Camshaft Phaser enables variable valve timing (VVT), a key technology that addresses the inherent trade-off between low-speed torque and high-speed power in traditional engines. During low-speed operation (e.g., idling or urban crawling), the phaser advances the intake camshaft phase, allowing the intake valves to open earlier, increasing the intake air volume and enhancing low-speed torque—ensuring smoother acceleration and reducing engine stalling. During high-speed operation (e.g., highway driving), the phaser retards the intake camshaft phase, delaying the intake valve closing time, which maximizes the intake air-fuel mixture and improves high-speed power output. Additionally, the phaser plays a vital role in reducing fuel consumption and exhaust emissions by optimizing the air-fuel ratio and combustion efficiency, aligning with Chery’s commitment to environmental protection and energy conservation.
The part number E4G16-1006040BC serves as a unique identifier for this intake camshaft phaser, distinguishing it from the exhaust camshaft phaser (with a different part number) and other components in the Jetour X70’s valve train (such as camshafts, valve lifters, or timing chains). It also differentiates the component from phasers used in other Chery or Jetour models (such as the Jetour X90 or Chery Tiggo 7), which are equipped with different engine models and have distinct dimensional and performance requirements. As a genuine OEM component, it strictly complies with Chery’s original design specifications, material standards, and performance requirements, while also adhering to international automotive quality and safety standards (ISO 9001, IATF 16949) and national emission standards (GB 18352.6-2016). Every dimension, mounting interface, and internal precision structure is engineered to match the Jetour X70’s E4G16 engine, ensuring perfect compatibility and seamless integration with the existing valve timing system. Unlike low-quality aftermarket phasers that often suffer from imprecise phase adjustment, oil leakage, or premature failure, the genuine E4G16-1006040BC Intake Camshaft Phaser undergoes rigorous testing and validation to ensure reliability, precision, and long service life, making it the preferred choice for Jetour X70 owners and professional automotive repair technicians.
2. Premium Material Selection & Precision Manufacturing Process
The Chery Jetour X70 E4G16-1006040BC Intake Camshaft Phaser is crafted from high-performance, automotive-grade materials, carefully selected by Chery’s engineering team to withstand the harsh operating conditions within the engine compartment—including exposure to extreme temperatures (ranging from -40°C to 150°C), high-pressure engine oil, continuous mechanical friction, and vibration. The team prioritizes materials that balance high strength, wear resistance, corrosion resistance, and dimensional stability, ensuring the phaser maintains precise performance over a service life of typically 120,000–180,000 kilometers under normal operating conditions (depending on usage environment and maintenance habits).
The core structure of the E4G16-1006040BC Intake Camshaft Phaser is made of high-strength 416 stainless steel, a premium automotive-grade material widely used in precision engine components due to its excellent mechanical properties. This stainless steel variant offers superior tensile strength (minimum 745 MPa) and yield strength (minimum 440 MPa), ensuring it can withstand the high mechanical forces and pressure exerted during phase adjustment. It also exhibits excellent wear resistance and low friction coefficient, reducing wear between the phaser’s internal components (such as the rotor and stator) and ensuring smooth, precise operation over time. Additionally, 416 stainless steel has good corrosion resistance against engine oil, additives, and moisture, preventing rust, deformation, or material degradation—critical for maintaining the phaser’s internal precision and sealing performance. The material is also easy to machine, allowing for the creation of complex internal structures with tight tolerances.
The internal components of the phaser, including the rotor, stator, and locking pin, are made of hardened 416 stainless steel, further enhanced through a heat treatment process (quenching and tempering) to improve surface hardness (up to HRC 58–62) and wear resistance. The phaser’s sealing components are made of high-temperature resistant nitrile rubber (NBR), which can withstand the high temperatures and pressure of engine oil, ensuring a leak-proof seal and preventing oil leakage that could compromise the phaser’s performance. The surface of the phaser is treated with a black oxide coating, which provides additional corrosion protection and reduces surface friction, extending the component’s service life.
The internal rotor and stator are machined using CNC precision lathes and milling machines, ensuring dimensional accuracy with a tolerance of ±0.01 mm—critical for precise phase adjustment. The oil passages and hydraulic chambers within the phaser are drilled with high-precision equipment to ensure smooth oil flow, which is essential for the phaser’s hydraulic-driven phase adjustment. The entire assembly undergoes rigorous quality control testing, including dimensional accuracy testing, pressure resistance testing, wear resistance testing, and fatigue testing. The fatigue testing ensures the phaser can withstand over 2 million cycles of phase adjustment without failure, meeting Chery’s strict durability requirements and ISO 16750 fatigue standards. Only phasers that pass all these tests are allowed to leave the factory, ensuring the E4G16-1006040BC series delivers reliable, precise performance in the Jetour X70’s E4G16 engine.
3. Structural Composition & Key Design Features
The Chery Jetour X70 E4G16-1006040BC Intake Camshaft Phaser features a precision-engineered hydraulic-driven structural design, tailored to the specific requirements of the Jetour X70’s E4G16 engine and its variable valve timing system. Its structural composition is optimized to ensure precise phase adjustment, fast response, and reliable operation, with key design features that address the unique challenges of dynamic valve timing control in modern engines.
One of the key design features of the E4G16-1006040BC Intake Camshaft Phaser is its hydraulic-driven rotor-stator structure, which consists of four main components: the stator, rotor, locking pin, and sealing ring. The stator is fixed to the engine’s timing cover and connected to the timing chain, which drives the stator to rotate synchronously with the crankshaft. The rotor is splined to the intake camshaft, allowing it to rotate relative to the stator within a certain angle (typically 30–40 degrees). The rotor and stator are designed with multiple hydraulic chambers and vanes, which are activated by high-pressure engine oil controlled by the ECU. When the ECU sends a signal, the oil control valve (OCV) directs high-pressure oil into the corresponding hydraulic chamber, pushing the rotor to rotate relative to the stator—adjusting the intake camshaft’s phase angle. The locking pin ensures the phaser remains in a default position (typically the most advanced phase) when the engine is turned off, preventing phase drift and ensuring smooth startup.
Another critical design feature is the optimized hydraulic chamber and vane design, which ensures fast response and precise phase adjustment. The hydraulic chambers are evenly distributed around the rotor, with precision-machined vanes that fit tightly within the stator’s grooves—minimizing oil leakage and ensuring efficient power transmission. The vane surfaces are coated with a low-friction material, reducing wear and ensuring smooth rotation. Additionally, the phaser is designed with a built-in oil pressure relief valve, which prevents excessive oil pressure from damaging the internal components, ensuring safe and reliable operation. The oil passages are optimized to ensure rapid oil flow, reducing the phaser’s response time to less than 50 milliseconds—critical for real-time adjustment of intake timing during dynamic driving conditions.
The E4G16-1006040BC Intake Camshaft Phaser also features a compact, lightweight design that fits perfectly within the Jetour X70’s engine compartment, minimizing space occupation while ensuring optimal clearance with other engine components (such as the timing chain, camshaft, and valve cover). The mounting interface is precision-machined to ensure secure attachment to the intake camshaft and timing cover, preventing vibration or loosening during engine operation. The phaser’s design also incorporates a dust-proof seal, which prevents dust, debris, and moisture from entering the internal components, further extending their service life. Additionally, the phaser is compatible with the Jetour X70’s timing belt system (as the Jetour X70 uses a timing belt rather than a timing chain for quieter operation), ensuring seamless integration with the engine’s timing system.
