It is a technology used in modern automobiles to increase fuel efficiency and reduce emissions. This technology has the ability to deactivate certain cylinders depending on the load condition of the engine. In this way, unnecessary fuel consumption is prevented at low load or cruising speed.
The engine shuts down certain cylinders when operating in low-power conditions. This is usually applied in multi-cylinder engines such as V6, V8. For example, a V8 engine can disable two, four or six cylinders.
When the power demand increases (for example, when accelerating or climbing a hill), the deactivated cylinders are reactivated. This allows the engine to reach its full power capacity.
