Automotive Crankcase Ventilation System Market Size:
Automotive Crankcase Ventilation System Market Size is estimated to reach over USD 2.28 Billion by 2032 from a value of USD 1.71 Billion in 2024 and is projected to grow by USD 1.74 Billion in 2025, growing at a CAGR of 3.9% from 2025 to 2032.
Automotive Crankcase Ventilation System Market Scope & Overview:
The automotive crankcase ventilation system is a crucial mechanism designed to remove unwanted gases from the crankcase of an internal combustion engine. These gases, which are combustion byproducts that leak past the piston rings, contaminate the engine oil, leading to sludge formation and corrosion. The ventilation system employs a network of tubes, a one-way valve, and a vacuum source, such as the intake manifold, to extract these harmful gases. In modern vehicles, this system is a closed-loop Positive Crankcase Ventilation (PCV) system, which redirects these gases back into the engine's intake to be combusted, thereby reducing harmful emissions and improving engine longevity.
How is AI Impacting the Automotive Crankcase Ventilation System Market?
AI is impacting the automotive crankcase ventilation system (CCVS) market by enabling predictive maintenance, optimizing system performance, and enhancing overall engine efficiency. AI-driven sensor technology and real-time data analysis allow for proactive maintenance, reduced downtime, and improved emissions control. Also, AI can optimize the CCVS operation based on real-time engine conditions, such as load and speed, to ensure optimal performance and fuel efficiency. Additionally, AI is driving the integration of CCVS components with other engine systems, such as the intake manifold or valve cover, for improved efficiency and packaging. This integrated approach can reduce assembly complexity, improve sealing reliability, and lower production costs.
Automotive Crankcase Ventilation System Market Dynamics - (DRO) :
Key Drivers:
Stringent emission regulations are driving the automotive crankcase ventilation system market growth
Regulations mandate the reduction of harmful emissions from vehicles, including blow-by gases from the crankcase. Crankcase ventilation systems, particularly closed-loop PCV systems, are essential for meeting these standards by redirecting these gases back into the engine. Regulations target specific pollutants found in blow-by gases, such as hydrocarbons (HC) and particulate matter (PM). Advanced CCV systems with better oil separation and filtration capabilities are required to meet these specific reduction targets, thereby driving the automotive crankcase ventilation system market size.
- For instance, the European Union has set targets to reduce net greenhouse gas emissions by at least 55% by 2030 compared to 1990 levels and aims for climate neutrality by 2050. Regulations on new passenger cars and vans have become increasingly strict since 2020, leading to a 27% reduction in average CO2 emissions from new cars between 2019 and 2022. These regulations indirectly drive the adoption of better engine technologies, including advanced CCV systems to improve overall engine efficiency and reduce emissions.
Consequently, stringent emission regulations are driving the automotive crankcase ventilation system market expansion.
Key Restraints:
Increasing adoption of electric vehicles (EVs) is restraining the global automotive crankcase ventilation system market growth
Crankcase ventilation systems are specifically designed to manage blow-by gases produced during the combustion process in internal combustion engines (ICEs). Since EVs are powered by electric motors and batteries, they do not have this combustion process and therefore do not require crankcase ventilation systems or their components like PCV valves, hoses, and filters. Additionally, government regulations and growing consumer preferences are driving a long-term shift towards electrification of the automotive sector. Many regions have set targets to phase out the sale of new gasoline and diesel vehicles in the coming decades which poses a significant restraint to the growth of the industry.
- For instance, India's electric vehicle market experienced a 20% sales increase in 2024, with EVs comprising over 50% of 3-wheeler sales, around 5% of 2-wheeler sales, and 2% of car sales. Also, the Indian EV battery market is projected to grow significantly, from USD 16.77 billion in 2023 to USD 27.70 billion by 2028.
Therefore, as per the analysis, these combined factors are significantly hindering automotive crankcase ventilation system market share.
Future Opportunities :
Advancements in filtration technologies are projected to create automotive crankcase ventilation system market opportunity
High-efficiency coalescing filters are specifically designed to capture these sub-micron oil droplets with efficiencies often exceeding 99% for particles down to 0.3 microns. Additionally, by effectively separating and returning oil to the crankcase, these filters help reduce overall engine oil consumption, leading to lower operating costs for vehicle owners and contributing to environmental benefits by reducing the need for frequent oil top-ups. Moreover, modern gasoline direct injection (GDI) and diesel engines produce higher levels of oil mist in their blow-by gases compared to traditional port fuel injection engines. High-efficiency coalescing filters are crucial for effectively managing this increased oil load and preventing issues associated with intake valve fouling in GDI engines, hence boosting automotive crankcase ventilation system market demand.
Hence, based on the analysis, advancements in filtration technologies are expected to create automotive crankcase ventilation system market opportunities.
