Description
Engine platform: Volkswagen EA111. This is a transverse, modular engine series, renowned for its reliability and economy.
Specific engine model: Mainly used for 1.6L MPI (multi-point fuel Injection) naturally aspirated engines.
Common engine codes: CLSA, BTS, CCSA, CDAA, etc.
Available vehicle models (wide range)
Volkswagen: Sixth-generation Golf (Golf VI), Jetta (Jetta MK5/MK6), Passat B6/B7 (Passat), Tiguan, Touran (Touran), Eos, Polo (Polo 6R), etc.
Audi: A1 (8X), A3 (8P), etc.
Skoda: Octavia 1Z, Superb 3T, etc.
SEAT: Leon 1P, Ibiza 6J, etc.
3. Detailed technical and physical properties
Material: High-strength ductile iron is adopted. This material, while ensuring sufficient strength and wear resistance, also features excellent casting performance and cost advantages.
Structure
Balance weights: It features 8 balance weights (4 pairs), which is a typical characteristic of a 1.6L displacement crankshaft. These weights are used to balance the inertial force and torque generated during engine operation, ensuring smoothness. In contrast, the crankshaft of the 1.4L EA111 engine on the same platform usually has only four balance weights.
Main journal: It is used to install the main bearing bush and connect it to the engine block. There are a total of 5 main necks, providing stable support.
Connecting rod journal: Connected to the big end of the connecting rod. There are a total of 4 connecting rod journal shafts with a phase Angle of 180°, which conforms to the working sequence of a four-stroke inline-four engine.
Oil passage: Inside the crankshaft, complex lubricating oil passages are drilled to transport engine oil from the main bearing to the connecting rod bearing, ensuring the lubrication of key friction pairs.
Front end: Install the timing pulley (to drive the valve train) and crankshaft pulley (to drive the generator, air conditioning compressor, etc. through the accessory belt).
The rear end: The flange is used to connect the flywheel (manual transmission) or the torque converter (automatic transmission).
4. Key Parameters (Examples, please refer to the maintenance manual for details)
Parameter item description
The total length is approximately 400-450mm (excluding the protruding part of the flange).
The total weight is approximately 12 to 15 kilograms (made of cast iron)
Stroke: 81.0mm (Stroke x cylinder bore: 81.0mm x 77.4mm = 1598cc)
The standard diameter of the main journal is usually within the range of 54.00 to 54.02 mm (with graded maintenance dimensions).
The standard diameter of the connecting rod journal is usually within the range of 47.80 to 47.82 mm (with graded maintenance dimensions).
