What is the difference between a four-cylinder and a six-cylinder engine?

[DylanRose]

The differences between a four-cylinder and a six-cylinder engine are as follows: 1. Different number of cylinders: A six-cylinder engine has six cylinders; a four-cylinder engine has four cylinders. 2. Different firing intervals: The firing order for a six-cylinder engine is 1, 5, 3, 6, 2, 4, with a firing interval of 60 degrees; the firing order for a four-cylinder engine is 1, 3, 4, 2, with a firing interval of 180 degrees. 3. Different number of intake or exhaust manifolds: A six-cylinder engine has six intake or exhaust manifolds; a four-cylinder engine has four. 4. Different structures: A six-cylinder engine has a more complex structure, larger size, greater weight, and more complicated layout. A four-cylinder engine has a relatively simpler structure with one fewer cylinder. From a structural design perspective, a six-cylinder engine has one more cylinder than a four-cylinder engine, along with corresponding additional camshaft accessories.
