Final answer:
A greater number of cylinders generally increases engine smoothness and power.
Step-by-step explanation:
A greater number of cylinders generally increases engine smoothness and power.
Engine cylinders are the chambers where fuel is burned to generate power. The more cylinders an engine has, the more power it can produce. This is because each cylinder can generate power independently, resulting in a smoother and more powerful engine.
For example, a 4-cylinder engine is generally less powerful and smoother than a 6-cylinder engine. Similarly, a 6-cylinder engine is less powerful and smoother than an 8-cylinder engine.
