Automotive Crank Case Ventilation System Market Drivers

Growing Demand for Improved Fuel Efficiency and Emissions Control

Crankcase ventilation systems are essential devices for the automotive industry by managing the flow of gases and vapors from the engine crankcase. Blow-by gases produced in the engine are discharged into the system, causing these gases, along with oil droplets with unburnt fuel and water droplets, to be extracted from such gases. These components are prevented from entering the intake manifold and combustion chamber by the system, which effectively separates oil droplets from the blow-by gases, coolant, and impurities, resulting in reduced engine wear and improved performance.The Automotive Crank Case Ventilation System Market Industry growth is anticipated to increase significantly over the period.

Advancements in Engine Technology and Design

The automotive industry is in a constant state of change as new engine designs and technologies are created to enhance performance and efficiency, among other things. As a result, changes have been made to the concept and operation of crankcase ventilation systems. For example, the use of turbochargers has increased the pressure and temperature of the blow-by gases. Any effective crankcase ventilation system must, as a result, be more efficient and higher capacity than previous systems.Similarly, since direct injection systems were introduced, oil vapor concentrations have increased as a result of decreased amounts of fuel diluted in the oil. As a response to that, new and improved crankcase ventilation systems were developed in order to be able to handle higher quantities of oil vapor.

Rising Popularity of Electric and Hybrid Vehicles

The increasing prevalence of electric and hybrid cars is likely to have a large effect on the Automotive Crank Case Ventilation System Market Industry. While traditional crankcase ventilation systems are not needed for electric cars, as these do not use an internal combustion engine, such systems are vital for hybrid vehicles. As hybrid vehicles run on both electric and internal combustion engines, they experience conditions not present in pure ICE vehicles that the crankcase ventilation system must be able to deal with.Therefore, the rise in popularity of electric and hybrid vehicles is likely to provide several new opportunities for the development and production of improved crankcase ventilation systems.
