Market Overview

Crank Case Ventilation Valve Market: Market Outlook

Crank case ventilation is a system that helps to eliminate harmful vapors from engine and helps to prevent vapors from being ejected into the atmosphere. The crank case ventilation valve is operational as both a pollution control device and as well as crank case ventilation system.

Since 1960s, crank case ventilation valve have been standard equipment on all new cars. However, not every petrol engines have these valves. Sometimes, dragsters use scavenger system (device) and venturi tube in the exhaust to take out combust gases and sustain a small quantity of vacuum in the crank case to avoid oil leaks on the track.

Owing to the growing importance to safeguard the global environment, efficient crank case ventilation valves are increasingly critical to diesel engine OEMs (Original Equipment Manufacturers). In future, globally diesel engine emission guidelines will require manufacturers to continue to reduce total particulate emissions.

Recent emission regulations in some countries and market sectors cover total engine emissions that include both crank case and tailpipe. Since crank case emissions contributes up to twenty five percent of total emissions, control of this air contamination source is critical to safeguard the earth’s environment.
