What is the difference between L4 and inline engines?

[MaverickLee]

Difference between L4 and inline engines: 1. Arrangement differs: Inline engines have all cylinders arranged in a single plane; L4 refers to an inline four-cylinder engine arrangement. 2. Characteristics differ: Inline engines feature lower manufacturing costs, higher stability, better torque characteristics, superior fuel economy, and wider application range; L4 engines are more compact with excellent stability, lower fuel consumption, but relatively lower engine power. Current engine types in the market include: inline engines, V-type engines, W-type engines, horizontally opposed engines, and rotary engines. Inline engines arrange cylinders in a straight line; V-type engines separate cylinders left and right with a certain angle between them, resembling a V shape; W-type engines further divide the V-type engine's sides into groups, appearing like a W; horizontally opposed engines represent the most mechanically balanced engine configuration for motion.
