Maintenance of CRDi system vehicle starts from fuel filter replacement.
Advanced technology of CRDi based diesel vehicles allows higher power and improved fuel efficiency than conventional disel system.
High-priced parts such as injectors and high-pressure pumps operating at high pressure of up to 1,630 bars are very sophisticated and delicate. If they are exposed to minute particles of slight moisture in the fuel, This leads to a great economic loss.
Therefore, in order to enjoy advanced CRDi system safely and comfortably, continuous and periodic fuel filter management is absolutely required.
If more than a certain amount of water accumulates on the bottom of the water filter, you can see the water separation warning light to exchange water filter. If you drive continously not to respect the warning light, water will penetrate into fuel system and it affects CRDi engine adversely.
So the Commong Rail engine has a water filter (water sensor) that separates water contained in the fuel and stores water separately from the fuel in the tank.
Oil film on the CRDi injector or the high-pressure pump prevents from friction and noise beterrn metals. non moisture filtered fuel deteriorates oil film and worsens fuel system. It is the main cause of malfunction of the fuel supply system and may cause wear and tear of parts.
A paraffinic(CnH2n+2) ingredients in fuel tends to solidify at zero degree Centigrade. Fuel filter to have heating device helps a lot to melt this paraffinic ingredients in the winter time.
The heater of the fuel filter, regardless of ECU control, operates according to ON/OFF of the fuel temperature control bimetal switch built in fuel filter. At minus 3 degrees Centigrade, Bimetal is turned on with the contact of the attached switch.
It dissolves the paraffinic ingredients in the fuel.
The fuel filter also has the function of separating foreign matter such as dirts and particles contained in disel as air filter or other filters do.
FILTER OVER THE EXCHANGE INTERVAL
It is not exaggeration to say that the first step to care disel vehicle is fuel filter replacement.
Fuel filter replacement for CRDi dissel vehicle is more and more important. Unfortunately, most drivers do not know the importance of fuel filter.
Suh Hung's i-filter will protect your precious CRDi vehicle.
- Every 30,000 km (typical)
- Every 15,000 km (in harsh conditions)
