DESCRIPTION
SYSTEM 1s
This starter kit will enable you to enter the exciting world of water injection: a high-power magnetic piston pump and a specially-designed atomising jet form the basis of this rugged system 1. The water-pump is activated when an adjustable pressure switch, fitted to the inlet manifold, reaches its preset point: delivery rate can be altered by changing water-jet sizes.
WATER PUMP
Specially designed and manufactured by ERL for the sole purpose of pumping water, its delivery rate is small but it generates a very high pressure; a minimum differential pressure of 3 bar is necessary for the ERL atomising jet. There are no mechanical links between the piston and the drive motor: the movement of the special magnetic stainless piston is induced by a powerful maganetic field generated by the on-board electronic controller. Flow and pressure characteristics are controlled by varying the frequency and the duration of the electrical pulse fed to the solenoid.    
ADJUSTABLE PRESSURE SWITCH
This switch determines the point where the system starts to inject. 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. The switch is a 'normally-closed' type, adjustable range is between 3-30psi, factory set at 10psi.
HOOD
This Nitride rubber cap is for protecting the electrical contacts on the pressure switch from the harsh environment in the engine bay  
STAINLESS IN-LINE WATER FILTER
Apart from perfoming the normal function, this filter can be back-flushed and re-used again and again. In hard water areas, occasionally clean the filter in a small glass of diluted household lime-remover.
WATER JET
The jet is made of nickel-plated brass with two spiral grooves cut into the centre insert. Water travels through these grooves, acquiring a swirling motion before leaving the small hole on the tip: the main function of this arrangment is to cause an atomising effect and turn the water into a fine mist. Of course a pressure of at least 3 bar is required. Jet sizes from 0.5mm to 1.0mm are available in 0.1mm increments. 0.5mm size is supplied with the standard kit, but alternative sizes can be supplied on request. Thread size of the jet is M8x0.75mm: this is not supplied with the kit but can be made available on a loan-and-return basis if necessary.
 
FUSED LOOM (pump)
The 3-wire loom is equipped with a 10A inline fuse. Wire size is very important as the pump draws large currents at start-up of every stroke (45 times/sec.): make sure a 30A wire is used if extension is necessary.
HARDWARE
All fasteners are made with high quality 316(A4) grade stainless steel: lower grade stainless steel does suffer from corrosion and pitting under the harsh environments of the engine bay
HOSE
The hose is made of nylon, whose natural strength can sustain pressure of over 12bar at 80°C. Lowest operating temperature is -40°C @26bars. The colour supplied with the kit is semi-translucent white, but red, yellow, green, blue and black are available on request.
