An interactive educational article that explains the functionality of internal combustion engines, starting from simple cranks and pistons to detailed animations of four-stroke cycles.
This article explains in depth the core value of hybrid cars: it is not the battery and electric motor themselves, but rather how they make the Atkinson cycle engine—which normally has poor low-end torque—practical, thereby significantly reducing fuel consumption. Taking the 2021 Toyota Sienna as an example, it elaborates on how the hybrid system achieves excellent fuel economy without compromising driving experience.
