Analysis by Component

Based on component, the automotive cylinder deactivation system market is segmented into engine control unit, value solenoid, and electronic throttle control.  The electronic throttle control (ETC) segment is the leading segment in the market. This part is essential for controlling engine performance and efficiency by accurately managing the air intake, which is crucial for optimizing cylinder deactivation systems. The capacity to modify throttle response improves the overall performance of vehicles, making ETC an important feature in numerous contemporary vehicles.

The value solenoid segment is experiencing growth as it plays a crucial role in regulating the oil flow for activating and deactivating cylinders. The valve solenoid plays a critical role in ensuring smooth transitions between active and inactive cylinders, which is becoming more important as automotive manufacturers strive to improve fuel efficiency and meet strict emissions regulations.

Analysis by Valve Actuation Method

Based on valve actuation method, the automotive cylinder deactivation system market is divided into overhead camshaft design, and pushrod design.

The pushrod design segment is the leading segment in the market. This particular design is commonly utilized in a variety of V6 and V8 engines, especially by companies such as General Motors and Chrysler, which have integrated cylinder deactivation technology in their pushrod engines. The pushrod design, commonly linked to classic American muscle vehicles and trucks, leverages well-established technologies, positioning it as a major player in the market.

The overhead camshaft design segment is expanding owing to advancements in overhead cam (OHC) engine designs that utilize variable valve timing and cylinder deactivation technologies. Automakers such as Honda and Mercedes-Benz are more and more utilizing camshaft designs in their latest models, leading to improved performance and efficiency. The increase in popularity of vehicles that are both fuel-efficient and environmentally friendly is fueling this expansion.

Analysis by Number of Cylinders

By number of cylinders, the automotive cylinder deactivation system market is divided into 4 cylinders and 6 cylinders and above.

The 6 cylinders and above segment dominates the market owing to the extensive use of cylinder deactivation technology in bigger engines, especially in V6 and V8 setups that are frequently seen in trucks and high-performance vehicles. These engines see a big advantage from cylinder deactivation, as they are able to run more efficiently when not under heavy load by turning off certain cylinders, therefore enhancing fuel efficiency and decreasing emissions.

The 4 cylinders segment is expanding driven by the rising use of smaller and more efficient engines in passenger vehicles. Car manufacturers are using cylinder deactivation in 4-cylinder engines more often to improve fuel efficiency and comply with strict emissions laws. Due to the change in consumer preferences toward vehicles that are fuel-efficient, this particular market segment is anticipated to experience notable expansion.

Analysis by Fuel Type

Based on fuel type, the automotive cylinder deactivation system market is divided into gasoline and diesel. The gasoline segment dominates the cylinder deactivation systems market. Cylinder deactivation technology has been widely embraced by gasoline engines due to its success in enhancing fuel efficiency and decreasing emissions, especially in light-duty vehicles and performance cars.

The diesel segment is expanding owing to the growing interest in utilizing this technology in diesel engines to regulate exhaust temperatures and enhance fuel efficiency.
