Automotive water separation system is a device that is used to ensure the purity of fuel which is delivered to the engine. The automotive water separation systems are installed in the automobile for the effective protection for engines.
The automotive water separation systems separate and remove water as well as solid contaminants in the fuel before it reaches the fuel pump. Presence of water in fuel wears off the lubrication in the fuel injectors and also reduces the work life of the engines.
The automotive water separation system removes the contaminants in the form of solid partials and water from the fuel and prevents the engine from getting clogged. Clean and pure fuel without contaminants prevents engine failure and enables the engine to run more efficiently.
It is observed that Diesel fuel generally contains a higher amount of water than that of gasoline or any other fuels. Which makes it a curtail system for a diesel engine or else, the unfiltered fuel with the contaminants will hamper the engine efficiency and also contributes to increase engine wear and tear.
Automotive water separation system is generally made of aluminium metal. Automotive water separation system separates and collects filtered contaminants which are later removed from the engine at the time of regular maintenance of the vehicle.
Automotive water separation system is available in various types on the basis of vehicle type. However, smaller separators need to be drained more often. Most automotive water separation system has a sensor informing the water level is in the device.
