The engine of your Kia uses air and fuel to produce power in order to drive the wheels forward or backward. This is done by simply compressing the two elements and burning it in a precise manner. However, after this so called combustion process, the engine creates harmful substances that are mostly corrosive and are dangerous both to the vehicle parts and human. The emission may contain several components such as carbon monoxide, nitrogen oxides, and hydrocarbons. These exhaust gases are very harmful that it can greatly contribute to smog and acid rain. Before the emission is being released from the engine, the crankcase collects some of the gases which may leak past the rings that surround the piston and contains them into the cylinder walls. If these gases are not released in due time, it can cause the engine to break down because of its corrosive effect. In order to release these 'leftovers', the positive crankcase ventilation or PCV valve is utilized. This device has a one way valve designed to ensure the continuous airflow inside the combustion chamber. It helps some of the emission to be released from the engine for a cleaner internal combustion engine. The Kia PCV valve is part of the PCV system which is long been used on most combustion engines to control emission flow. Every Kia vehicle has a particular specification of PCV valves, as its size is significant in restricting the correct amount of air that is drawn out from the crankcase and into the intake manifold. Once it needs replacement, you should obtain the correct size for reliable performance.
