H150061300
Product Details
1. Basic Overview & Core Functional Positioning
The H150061300 Exhaust Phaser, also widely known as the Exhaust Variable Valve Timing (VVT) Phaser or exhaust camshaft adjuster, is an authentic OEM factory component exclusively designed and manufactured for the Changan CS35 compact SUV series. Matching the official OEM code 1006040-B01, this precision engine part serves as a core executive component of the engine’s variable valve timing system, specially calibrated for the conventional naturally aspirated powertrain equipped on early-generation Changan CS35 models produced from 2012 to 2018. Installed directly on the end of the engine exhaust camshaft, this phaser works in real-time coordination with the engine control unit (ECU) and oil control valve to dynamically adjust the opening and closing timing of exhaust valves according to diverse engine operating conditions, including idle speed, low-speed cruising, high-load acceleration, and high-speed driving.
Unlike fixed camshaft timing structures, the H150061300 exhaust phaser solves the performance bottlenecks of traditional engines with rigid valve timing settings. At idle and low engine speeds, it delays exhaust valve closing to stabilize idle operation, reduce engine jitter, and lower fuel consumption. During high-speed and heavy-load operation, it advances exhaust valve timing to accelerate exhaust gas discharge, reduce residual exhaust gas inside the combustion chamber, improve intake and exhaust efficiency, and effectively boost engine power output and combustion efficiency. Meanwhile, precise exhaust valve timing adjustment optimizes the engine’s air-fuel mixing ratio, minimizes incomplete combustion, and lowers harmful exhaust emissions, fully complying with Euro 4 and domestic automotive emission standards for matched Changan CS35 models. This part is a dedicated exhaust-side phaser, strictly distinguished from the intake phaser (H150060300), with non-interchangeable structural parameters and control logic.
As a model-specific genuine Changan component, the H150061300 phaser strictly follows Changan’s original design specifications and global quality management systems including ISO 9001 and IATF 16949. All dimensional tolerances, oil circuit matching parameters, and gear tooth precision are precisely calibrated for the Changan CS35’s 1.6L naturally aspirated engine. It is incompatible with other Changan models such as Eado, UNI-T, or other displacement variants of the CS35 series, nor can it replace modified or aftermarket VVT phasers. Inferior replacement parts often cause abnormal engine noise, unstable idle speed, weak power acceleration, and increased fuel consumption, while the genuine H150061300 phaser ensures long-term stable operation and consistent engine performance throughout its service life.
2. Material Selection & Manufacturing Standards
The H150061300 Exhaust Phaser adopts high-strength automotive-grade metal materials and precision industrial processing technology to adapt to the harsh high-temperature, high-pressure, and high-frequency friction operating environment inside the engine compartment. The outer gear body and main rotor assembly are forged from high-quality alloy structural steel, which features excellent tensile strength, wear resistance, and high-temperature deformation resistance. After overall quenching and tempering heat treatment, the material hardness reaches the standard automotive mechanical level, effectively resisting long-term impact friction from high-speed camshaft rotation and avoiding gear tooth wear, deformation, or tooth jumping failure.
The internal hydraulic adjustment chamber and oil seal structure adopt high-precision aviation-level sealing materials and wear-resistant alloy gaskets, which can maintain stable sealing performance under extreme temperature changes ranging from -30°C to 150°C and long-term impact of high-pressure engine oil circulation. This design effectively prevents internal oil leakage, pressure loss, and VVT system failure caused by poor sealing. The gear teeth adopt micro-precision grinding technology, with a 36-tooth standard structure dedicated to the CS35 exhaust camshaft, ensuring zero deviation in meshing accuracy and rotation clearance with the timing chain.
The entire production process implements strict automated assembly and quality inspection procedures. Each finished phaser undergoes hydraulic pressure resistance testing, high-speed rotation fatigue testing, tightness testing, and dimensional full-inspection to eliminate defective products with unqualified oil circuit conduction, excessive rotation clearance, or poor sealing. Through salt spray corrosion resistance testing and long-cycle durability verification, the genuine H150061300 phaser achieves excellent corrosion resistance and fatigue resistance, with a normal service life of over 100,000 kilometers, far exceeding the durability level of ordinary aftermarket cast phasers.
3. Structural Composition & Working Principle
The H150061300 Exhaust Phaser features a mature and reliable hydraulic VVT adjustment structure, mainly composed of three core parts: external timing gear, internal hydraulic rotor assembly, and precision sealing and locking mechanism. The external gear meshes with the engine timing chain to receive crankshaft power and drive the exhaust camshaft to rotate synchronously. The internal rotor is connected and fixed with the exhaust camshaft, and the independent hydraulic oil chamber inside the phaser divides the oil path into advance and delay cavities, which are controlled by the engine’s oil control valve.
During engine operation, the ECU collects real-time data such as engine speed, throttle opening, and coolant temperature, and sends control signals to the VVT oil control valve to adjust the flow direction and pressure of engine oil entering the phaser’s internal cavity. When high-pressure engine oil enters the advance cavity, it pushes the rotor to rotate relative to the outer gear, advancing the exhaust valve timing; when oil enters the delay cavity, it delays the exhaust valve closing time. When the engine is started or idling, the built-in mechanical locking pin automatically locks the rotor and gear into a fixed state, preventing timing deviation and ensuring stable cold start and idle operation.
Compared with ordinary phaser products, the H150061300 is optimized for the CS35 engine’s exhaust gas discharge characteristics. Its internal oil circuit flow and rotor rotation angle range are precisely calibrated to match the 1.6L engine’s air intake and exhaust volume, achieving more sensitive and accurate valve timing adjustment. The optimized locking structure effectively solves the common problems of loose locking and abnormal rattling noise of old-fashioned phasers, significantly improving the smoothness of engine operation.
