The inline engine tends to be smoother than V engine and are less complex with fewer parts. Inline engines are harder to mount, and can have balance/vibration issues.
The typical firing order of Inline four cylinder engine is 1-3-4-2. Firing order in a multi-cylinder engine is arranged so that the torsional moment is even and the load is uniformly distributed on longitudinal direction of the crankshaft. An even firing order will increase the balance of engine.
