The ValveCare system is an electronically controlled dosing system for petrol engines (MPI, DPI, DI, DI-MPI) that are converted to LPG or CNG. Together with the Prins ValveCare additive, the system aids to keep the combustion chamber cleaner, reduce wear of valves, valve seats and the petrol injectors.

Why should you use ValveCare? 

The valves and valve seats in a number of engines are more susceptible to wear when they run on LPG or CNG. This problem does not arise with petrol engines because petrol contains specific additives that lubricate the valves and valve seats. These additives are not present in LPG and CNG. The ValveCare-DI metering system injects these additives in exactly the required ratio with the LPG or CNG to prevent excessive wear.

How to use ValveCare?

The ValveCare additive has a consumption ratio of 1 litre additive to 1,000 litres of LPG. The additive reservoir can be refilled at any time. In case the additive reservoir is empty, the Prins switch will indicate a blue exclamation mark (blinking), and the engine can run another 4 hours on LPG. After this period, the engine will only run on petrol and the exclamation warning will stay visible. Filling up the additive-reservoir with ValveCare will remove the warning.

ValveCare additive:

• One bottle of ValveCare (1L) is sufficient for approx. 1,000 litres of fuel.
• Do not use or mix other additives with the original Blue Prins ValveCare additive. Use of other additives can harm the system and any warranty will become invalid.
• For more information and to buy bottles of ValveCare, please contact us or your official installer.
  

ValveCare-3 is completely integrated in the Prins LPG/CNG systems. The Prins ValveCare additive has proven to be reliable, effective and efficient.

The following components are installed in the engine compartment of a converted car:

1. The computer: to ensure system control.
2. The injectors: to inject the correct amount of ValveCare per cylinder.
3. The additive-reservoir: for the ValveCare fluid.
