Retired System Information

The water-pump is activated when an adjustable pressure switch, fitted to the inlet manifold, reaches its preset point: This amount is subject to change until you make payment. RACE PUMP INFO We have ruled out the widely available centrifugal pump as the pumping mechanism, because it is always coupled to a high rotational-speed drive-motor for efficiency reasons, hence it is prone to wear; further problem arises when the water inside the pump is frozen, the drive motor has to be detached from the vane by a slipping clutch arrangement so drive-motor windings cannot be damaged as a result of jamming, this led to unnecessary expenses and complicated mechanical links.

The special magnetic stainless armature is set in motion by strong magnetic field aqamist by a powerful solenoid.

Developed with years of experience in World Rally Championship racing and feedback from the industry by the most demanding users, the HFS-6 surpasses all other systems in operation, performance, and reliability. The ERL electro-magnetic pump is the result of a two-year intense mechanical and electronic research and development program. Aquamist 2s The 2s is a fully-mappable water-injection system, is pre-pressurizedequipped with diagnostic circuitry, able to detect blocked water-jet and abnormal operation problems.

Seller assumes all responsibility for this listing. How does it work? San Diego, California, United States.


Water is being filled and retained between the two valves during the induction stroke armature is pulled against the springwater is then pushed out by the action of compressed spring and the armature when the electric-field is nfs-6, high pressure is the product of spring force and the cross-section area of the armature tip.

It is normally fitted to the vacuum side of the inlet manifold 2D mode for applications where load signal throttle angle sensor or manifold absolute pressure sensor MAP sensor is available.

MF2 MF2 is the brain of the system, ultimately responsible for the vital functions of metering the water delivery rate. The fixed injection rate of the HFS-1 suits this application aquanist, and with the best failsafe system in the industry, is a great choice.

Jfs-6 is then delivered without being in contact with the drive-motor, pressure and delivery rate is regulated by internal high-tech electronic circuitry. Flow and pressure characteristics are controlled by varying the frequency and the duration of the electrical pulse fed to the solenoid. In addition, high speed drive motor tends to suffer from burn-out under prolonged continuous running.

Refinements such as flow rate and block jet detection can easily be obtained with a minimum of signal conditioning parts, to achieve a fully integrated water injection system with diagnostic capablities. Peak pressure can go as high as psi!

Sign in for more lists. An additional pair of wires supplies a stablised output voltage of 5 volts hhfs-6 driving a MAP manifold absolute pressure sensor. A high pressure pump with NO mechanical links, thus eliminated damages caused by jamming.

In addition, it has diagnostic circuitry designed to detect blocked water-jets and cut pipes. The similarity ends when the manual pump actions is replaced by electro-magnetic fields and speed is also cranked up to about 50 strokes a second!


Jet sizes from 0. Its primary function was to regulate the water pressure during injection and idle periods set at 5 bars.

The MF2 uses incoming RPM and pressure signals from the sensors in the engine bay and compares them with a pre-programmed map set by the user. In reference to the schematic diagram on the bottom of this page, the only parts that require interfacing is the HSV High Speed Valve.

This inline valve is made of high grade stainless steel. The system provides a pre-pressurized water line up to 8 bars and the flow rate is metered by our High Speed Valve HSV.

In hard water areas, occasionally clean the filter in a small glass of diluted household lime-remover. For applications where load signal throttle angle sensor or manifold absolute pressure sensor MAP sensor are available, the MF2 can read these signals and perfom 3-D mapping functions. A special output link from the ECU can inform other systems in the event of a fault condition, so boost-pressure can be lowered to minimize engine damage.

Two colored LEDs are mounted on the top side of the box.

There are no mechanical links between the piston and the drive motor: Electrical and Mechanical specifications Condition Input Voltage: Aquamisst of add to list layer. It just cannot be simpler for the user. It reads the pulsed signal from the center pin of the Aquamist pump and compares it to the water valve pulses, flags an error signal to yet another 1.
