 | | Firstly, it bridges the gap between 4 and 6-cylinder engines, thus may offer the best cylinder capacity for optimized efficiency; Secondly, compare with 4-cylinder engines, it saves one balancer shaft; Thirdly, compare with 6-cylinder engines, it is short enough to be fitted transversely into the engine compartment of front-wheel-drive cars, driving directly the inline gearbox. |
 | | However, it generates end-to-end vibration like 3-cylinder engines, because piston 1 is not in the same position as piston 5, and piston 2 is not in the same position as piston 4. |
 | | Obviously, the solution is the same as 3-pot engines, that is, employ a balancer shaft on which there are counter weights moving in the opposite direction to the pistons. |
