😃Inline 4 engines achieve perfect primary balance through the use of inertial forces
🔥Boxer 4 engines achieve perfect primary balance through piston masses and crankshaft design
🚀V4 engines achieve perfect primary balance through crankshaft counterweights
🛠️The V4 engine offers more modular design options compared to the inline 4 and boxer 4 engines
🏎️Inline 4 and boxer 4 engines are commonly used in cars, while V4 engines are more common in motorcycles
What is primary balance?
—Primary balance refers to the balance of forces in an engine caused by the changing direction of the piston. It is achieved through various methods depending on the engine configuration.
What is secondary balance?
—Secondary balance is the balance of forces caused by the motion of the connecting rod. It can create vibrations and is typically mitigated through the use of balance shafts or smart engine mount design.
Why are V4 engines more common in motorcycles than cars?
—V4 engines provide more modular design options and unique firing intervals that can enhance rear tire grip and power delivery. In motorcycles, where vibrations are more tolerable, V4 engines offer a desirable combination of performance and character.
Do all inline 4 and boxer 4 engines have the same characteristics?
—While there are common characteristics among inline 4 and boxer 4 engines, such as the basic cylinder layout, variations in bore, stroke, and crankshaft design can lead to differences in performance, sound, and feel.
What are the advantages of balance shafts?
—Balance shafts can help eliminate vibrations caused by primary and secondary forces in an engine. However, they increase complexity, cost, and friction, which can affect overall engine performance.
