What is the difference between a 4-cylinder engine and a 3-cylinder engine?

[MadelynLynn]

4-cylinder engine and 3-cylinder engine differences are: 1. Different weight: The 3-cylinder engine is smaller and lighter, making it easier to fit into many vehicle models without worrying about space constraints, which is beneficial for overall vehicle layout and aligns with lightweight body design principles, while the 4-cylinder is slightly heavier; 2. Different stability: The 3-cylinder arrangement cannot achieve symmetry like the 4-cylinder, resulting in uneven force distribution during operation, which causes the 3-cylinder engine to vibrate more than the 4-cylinder. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term engine can refer to both the power-generating device and the entire machine including the power unit.
