Our manufacturing process at Hebei Oujia includes advanced coordinate measuring machine (CMM) verification to ensure all critical dimensions align precisely with OEM specifications. Each Engine Assembly for EA111 1.6 L for AUDI VW undergoes comprehensive testing that simulates real-world operating conditions, verifying:
Proper installation of your Engine Assembly for EA111 1.6 L for AUDI VW is critical for optimal performance:
The cylinder head is manufactured from high-silicon aluminum alloy (AlSi7Mg) using low-pressure die casting, which provides excellent thermal conductivity and reduces weight by approximately 25% compared to traditional cast iron heads. Internal coolant passages utilize precision-cast geometries to optimize cooling around exhaust ports.
Standard compression for the EA111 1.6L ranges between 10.3:1 to 10.7:1 when measured at sea level with engine at operating temperature. Cylinder-to-cylinder variation should not exceed ±0.2 ratio units. Hebei Oujia's assemblies undergo leak-down testing to ensure less than 3% pressure loss at 6-bar test pressure.
The assembly is compatible with MED 9.5.10, SIMOS 8.3, and Bosch ME7.5 engine control units. For Euro 5 variants, it requires integration with the upgraded intake manifold with integrated tumble flaps and corresponding sensor wiring harness modifications.
Our assemblies feature tri-metal lead-free bearings with aluminum-tin-silicon running surfaces (AlSn20Si) on steel backing. Main bearings are 53.0mm diameter with 0.5mm wall thickness, while connecting rod bearings are 47.8mm diameter with advanced polymer overlay for improved embeddability.
We install the upgraded gear-type oil pump with crescent design (06H115251K) that delivers 24 L/min flow at 2000 rpm with maximum pressure relief setting of 4.5 bar. The pump features sintered steel gears with phosphate coating for improved wear resistance.
The timing system employs a reinforced toothed belt (contitech CT1043) driving dual overhead camshafts with a hydraulic tensioner that maintains 580±50 N tension. Proper timing requires alignment of crankshaft TDC marker with corresponding camshaft alignment pins using VW special tool T10171.
All assemblies meet IATF 16949:2016 automotive quality standards and are produced under VDA 6.3 process auditing. Each completed assembly receives unique traceability documentation including material certifications, dimensional reports, and performance validation data.
The Engine Assembly for EA111 1.6 L for AUDI VW continues to be a benchmark for reliability in compact powertrains despite newer engine families entering the market. Our engineering team at Hebei Oujia has implemented numerous improvements in our remanufacturing process:
With over 15,000 successful installations globally, Hebei Oujia has established itself as a leading technical partner for AUDI and VW service centers requiring premium engine solutions.
