Automotive Crankcase Ventilation System Market - Size, Share, Industry Trends, and Forecasts (2025 - 2032)

By Technology Type:

Based on the Technology Type, the market is categorized into Open Crankcase Ventilation (OCV) and Closed Crankcase Ventilation (CCV)/Positive Crankcase Ventilation (PCV).

Trends in the Technology Type:

• Growing trend towards the adoption of CCV to redirect blow-by gases back into the engine's intake manifold to be combusted, significantly reducing harmful emissions.
• OCV systems are mostly limited to older vehicles or specific off-highway applications where emission regulations are less stringent.

Closed Crankcase Ventilation (CCV)/Positive Crankcase Ventilation (PCV) accounted for the largest revenue share in 2024 and is also projected to witness the fastest CAGR.

• PCV systems integrate sensors and electronic control units (ECUs), which allow for dynamic adjustment of the PCV valve operation based on engine load and conditions, hence driving the automotive crankcase ventilation system market share.
• Trend towards integrating the PCV system with other engine components, such as the intake manifold or valve cover, for improved efficiency and packaging.
• Electrically assisted PCV systems are emerging to ensure proper crankcase ventilation under positive intake pressure conditions, further boosting the automotive crankcase ventilation system market trend.
• For instance, Caterpillar introduced its Cat CCV System for G3600 engines, an affordable and easily installed solution that can cut methane emissions by as much as 20%, aiding in the achievement of climate goals. This system also streamlines regulatory compliance by removing the necessity for users to measure, track, and report crankcase emissions.
• Thus, as per the automotive crankcase ventilation system market analysis, the aforementioned factors are driving the Closed Crankcase Ventilation (CCV)/Positive Crankcase Ventilation (PCV) segment growth.

By Sales Channel:

Based on the Sales Channel, the market is classified into Original Equipment Manufacturer (OEM) and Aftermarket.

Trends in the Sales Channel:

• OEMs are demanding more integrated CCV systems, tailored to specific engine designs and emission control strategies.
• Large existing fleet of internal combustion engine vehicles drives the need for replacement CCV components in the aftermarket.

Original Equipment Manufacturer (OEM) accounted for the largest revenue in 2024.

• Trend toward the adoption of advanced filtration and separation technologies in OEM-supplied systems to meet stringent emission regulations is driving the automotive crankcase ventilation system market demand.
• OEMs are pushing for lighter and more compact CCV system designs to contribute to vehicle fuel efficiency and packaging optimization.
• Thus, as per the automotive crankcase ventilation system market analysis, the aforementioned factors are contributing significantly to driving the industry size.

Aftermarket is predicted to register the fastest CAGR during the forecast period.

• Growing trend towards online sales of automotive parts, including CCV components, is increasing due to convenience and wider product availability is reshaping the traditional distribution channels.
• Vehicle owners are seeking high-quality and durable replacement CCV components to ensure optimal engine performance and compliance with emission standards.
• Further, the increasing average age of vehicles on the road is a key driver for the aftermarket, as older vehicles require more frequent maintenance and replacement of components.
• Subsequently, as per the market analysis, the aforementioned factors are collectively responsible for accelerating the industry growth during the forecast period.

By Vehicle Type:

Based on the vehicle type, the market is categorized into passenger vehicles, light commercial vehicles, and heavy commercial vehicles.

Trends in the Vehicle Type:

• Heavy Commercial Vehicles (HCVs) with large, powerful engines require heavy-duty CCV systems capable of managing significant volumes of blow-by gases.
• HCVs face stringent regulations regarding nitrogen oxides (NOx) and particulate matter emissions, driving the adoption of advanced CCV technologies.

Passenger Vehicles accounted for the largest revenue share of 48.29% in 2024.

• Stricter emission standards like Euro 6 and Bharat Stage VI are driving the adoption of more efficient crankcase ventilation systems to minimize hydrocarbon emissions.
• Consumers' preference for fuel-efficient vehicles is compelling manufacturers to integrate advanced CCV systems that optimize engine performance and reduce fuel consumption.
• Rising need for smaller and lighter CCV systems to align with the trend of vehicle weight reduction for improved fuel economy.
• For instance, the Indian passenger car market is projected to grow at over 9% annually from USD 32.70 billion in 2021 to USD 54.84 billion by 2027.
• In conclusion, the aforementioned factors are contributing to the growth of the global automotive crankcase ventilation system market size.

Light Commercial Vehicles is predicted to register the fastest CAGR during the forecast period.

• For LCVs used in demanding logistics and delivery services, the focus is on robust and reliable CCV systems that can withstand heavy-duty operations and ensure engine longevity.
• Crankcase ventilation systems in LCVs are designed to maintain optimal engine performance under various load conditions, ensuring efficiency and reducing downtime.
• Additionally, the surge in e-commerce and last-mile delivery services is driving the production of LCVs, thereby driving the automotive crankcase ventilation system market trend.
• Subsequently, as per the market analysis, the aforementioned factors are collectively responsible for accelerating the market growth during the forecast period.
