The differences between single-cylinder and twin-cylinder engines are as follows: I. Different Structures 1. Single-cylinder engine: When a single-cylinder engine operates, only one set of components is in motion. 2. Twin-cylinder engine: Consists of two identical single-cylinders arranged within one engine block, sharing a single crankshaft to output power. II. Different Characteristics 1. Single-cylinder engine: Due to its simple structure, compared to multi-cylinder engines of the same displacement, it features lighter weight and smaller structural dimensions. 2. Twin-cylinder engine: Equipped with features such as oil jet cooling for pistons, an oil cooling system, and a double overhead camshaft valve train. III. Different Operational Characteristics 1. Single-cylinder engine: In terms of operational continuity, single-cylinder engines operate less smoothly, with more significant speed fluctuations, making them prone to stalling. 2. Twin-cylinder engine: Suitable not only for power generation devices but also for entire machines including power units.
