Automotive Engine Assembly Line

The engine automation production line, as a core component of the power system, integrates advanced technologies such as high-precision machining, intelligent assembly, and digital inspection into its automated production line, covering the manufacturing and final assembly of key parts like the cylinder block, crankshaft, and pistons. Here is a comprehensive analysis of the engine's automated production line.

Core automation equipment and technology

Smart machining equipment

• Flexible Manufacturing Cell (FMC):

A machining center completes all processes for the cylinder block (tool change time ≤ 3 seconds)

• Adaptive compensation system:

Automatically adjusts machining parameters based on tool wear data

Data Management System

• MES System:

• Trace processing data for each engine (such as crankshaft roundness, bolt torque)

• Digital Twin:

• Virtual commissioning optimizes assembly cycle time (reduces downtime by 20%)

Comparison of typical engine production line

Engine type	Production line characteristics	Key technologies
passenger car gasoline engine	High tempo (60-90 seconds per unit), lightweight design	Aluminum alloy cylinder body machining deformation control
commercial vehicle diesel engine	Heavy components (cylinder ≥ 300 kg), high-torque assembly	Main bearing bolts tightened (500 N·m)
hybrid-specific	Electric motor-engine coupling workstation	Electric motor-engine coupling workstation
