E4T15C-1118010
Product Details
1. Basic Overview & Core Functional Positioning
The E4T15C-1118010 Turbocharger Assembly is a genuine OEM high-precision power enhancement component exclusively matched with the Chery Tiggo 8 PRO Max mid-size SUV, perfectly supporting the vehicle’s ACTECO SQRE4T15C 1.5T turbocharged gasoline engine platform. As the core power boosting unit of the engine intake and supercharging system, this turbocharger is installed at the engine exhaust manifold position, serving as a key component that improves engine power density, combustion efficiency and overall dynamic performance. It replaces natural atmospheric intake with forced supercharging, effectively solving the power insufficiency of small-displacement engines, and balances high power output, fuel economy and low emission performance, becoming the core hardware support for the excellent driving performance of Chery Tiggo 8 PRO Max.
Different from ordinary universal turbochargers, the E4T15C-1118010 assembly is precisely calibrated for the 1.5T high-efficiency engine parameters of Tiggo 8 PRO Max. It professionally recycles high-temperature exhaust gas energy that would otherwise be wasted, converts exhaust kinetic energy into mechanical rotation power, and drives the compressor wheel to pressurize ambient air. The compressed high-density air enters the engine cylinder after intercooling, increasing the oxygen content per unit combustion volume, enabling full atomization and combustion of fuel, and significantly lifting engine horsepower and torque output. This technology effectively improves low-speed torque responsiveness, eliminates turbo lag at start and low-speed acceleration, and greatly enhances the vehicle’s overtaking ability and climbing performance while optimizing fuel combustion efficiency and reducing exhaust emissions.
The part number E4T15C-1118010 is a dedicated exclusive specification for Chery E4T15C engine models, perfectly compatible with Tiggo 8 PRO Max, and also matches partial Chery Tiggo 7 Pro and Tiggo 5X Pro 1.5T versions. It features exclusive turbine wheel size, compressor flow parameters, boost pressure threshold and mounting interface dimensions, which cannot be interchanged with turbochargers of 2.0T engines or other Chery power platforms. Manufactured in strict accordance with IATF 16949 international automotive quality system and Chery’s original power calibration standards, it avoids common defects of inferior aftermarket turbochargers such as unstable boost pressure, serious lag, oil leakage and high-temperature failure, maintaining long-term stable power output of the original vehicle.
2. Material Selection & Manufacturing Standards
The E4T15C-1118010 Turbocharger Assembly adopts aviation-grade high-temperature resistant alloy and precision casting materials, specially optimized for extreme working conditions of long-term high-temperature exhaust impact, high-speed rotation and alternating pressure load. The turbine shell is made of high-temperature resistant cast iron alloy, which can withstand instantaneous exhaust temperature exceeding 950°C without thermal deformation or cracking, maintaining stable structural rigidity under long-term high-temperature cyclic working conditions. The internal turbine impeller is forged from high-strength heat-resistant stainless steel, processed by five-axis linkage precision milling, with ultra-high rotational balance accuracy and fatigue resistance, adapting to ultra-high-speed rotation of over 120,000 revolutions per minute.
The compressor shell adopts lightweight high-precision aluminum alloy die-casting molding, featuring high strength, low weight and good heat dissipation performance, which effectively reduces engine front load and improves dynamic response sensitivity. The core floating bearing and thrust bearing components adopt high-precision alloy materials with ultra-low friction coefficient and high-temperature wear resistance, ensuring flexible operation and low-loss power transmission under extreme high-speed and high-temperature environments. The internal oil seal and air seal components use multi-layer composite high-temperature resistant sealing materials, which can effectively prevent engine oil penetration and air pressure leakage, solving the common failure problems of turbocharger oil burning and boost pressure loss. All welding and assembly interfaces adopt automated precision processing to ensure tight fit and no air leakage or oil leakage.
All finished E4T15C-1118010 turbocharger assemblies pass strict professional factory tests, including high-speed dynamic balance calibration, full-range boost pressure testing, high-temperature durability cycle testing, sealing performance testing and engine bench matching verification. Each product undergoes precise boost pressure parameter calibration according to Tiggo 8 PRO Max power tuning data, ensuring consistent supercharging efficiency and stable power output. Strict quality screening eliminates defective products with unbalanced rotation, insufficient pressure build-up and poor sealing performance, fully meeting Chery’s high-standard power reliability and long-service-life requirements.
3. Structural Composition & Working Principle
The E4T15C-1118010 Turbocharger Assembly adopts a mature and reliable NGT13Z single-scroll supercharging structure, which is highly integrated and compact, perfectly matching the layout space and pipeline interface of Chery Tiggo 8 PRO Max 1.5T engine. The whole assembly mainly consists of high-temperature resistant turbine mechanism, aluminum alloy compressor mechanism, precision floating bearing intermediate body, electronic wastegate control valve, internal lubrication and cooling pipeline system, and sealing assembly. The integrated modular design realizes standardized installation, accurate positioning and stable operation, with no need for secondary modification during assembly.
Its core working principle follows exhaust gas energy recovery and forced air supercharging circulation. When the engine is running, high-temperature and high-pressure exhaust gas discharged from the cylinder impacts the turbine impeller to drive it to rotate at ultra-high speed. The coaxial compressor impeller rotates synchronously to suck and compress ambient air, greatly increasing air density and intake volume. After being cooled by the intercooler, the high-pressure dense air is sent into the engine cylinder to realize full combustion of fuel, thereby significantly improving engine power and torque. The built-in electronic wastegate valve can automatically adjust the boost pressure according to engine speed and load, effectively preventing overpressure damage and maintaining supercharging pressure within the optimal working range.
Equipped with a perfect circulating lubrication and cooling system, the turbocharger relies on engine oil circulation to lubricate high-speed rotating bearings and take away accumulated high-temperature heat, avoiding ablation and stuck failure of high-precision components under long-term high-load operation. The optimized single-scroll flow channel design effectively reduces turbo lag, improves low-speed pressure build-up efficiency, realizes sensitive power response at low and medium speeds, and ensures smooth power output and linear acceleration feeling of Tiggo 8 PRO Max in daily driving and high-speed overtaking scenarios.
