Polaris is the STARGAS solution for phased sequential electronic injection for LPG in the gaseous phase, in controlled ignition engines equipped with lambda probe and a three-way catalyzer

Created Using the most advanced design and production technology, Polaris itself extremely advantageous in terms of safety, affordability and environmental impact, guaranteeing total compliance with the most recent quality standards established by regulation ONU ECE R67- 01 and the EURO 3 and EURO 4 anti-pollution directives. Polaris  belongs to the sector's latest generation of products utilizing electronic injection devices to supply power to the motor. Its benefits are distinct and of definite interest - increased and performance and reduced levels of consumption and noxious emissions.

The POLARIS - Phased Sequential Gas Injection , retrofit system is made using the most advanced design and manufacturing technologies and allows a new generation of LPG system to be installed on vehicles.

The performances of the modern gas ECU - ELIOS, make the "master-slave" management of electronic injection of LPG in gaseous phase, in controlled ignition engines with or without lambda probe and catalytic converter.

In the "master-slave" mode, the gas ECU [slave] elaborates the injection signals coming from the car's original petrol ECU [master] and commands the functioning of the gas injectors. This means that the functioning strategy of the gas supply imitates the petrol functioning strategy (phased sequential, semi sequential, full unit etc). This functioning strategy is possible due to gas electro-injectors that ensure opening / closing times similar to those in petrol injectors.

Therefore, the new POLARIS retrofit system leads to;

" Greater Reliability
" Higher Performances
" Lower Pollution
" Lower Gas Consumption

This system is designed in compliance with the most recent European technical regulations and is type - approved based on the UNECE R67-01-UNECE R115-00 regulations.

ELECTRONIC CONTROL UNIT
Elios is from the latest generation  of electronics control units capable of producing phased sequential injection in the gaseous phase. unlike what usually occurs in older systems , Elios works in perfect symbiosis with the control unit of the original petrol powered plant, processing all the signals needed to determine the appropriate amount of LPG to send to the engine. It incorporates emulators for the petrol injectors and independently manages the change to gas after commutation (in accordance with the operation temperature ), the transitory phases and the diagnosis strategies: enrichment under full load, fuel dropping out (cut-off), restriction of peak rpm, and change to petrol in case of malfunction.

COMMUTATOR
Its essential and modern design along with the extremely compact dimensions facilitate installation inside the car. The commutator is an electronic device that permits the changeover between the two existing fuel supply systems installed in the car, by means of an appropriate selector. The change to gas always depends on the engine temperature; Elios electronic control unit is the device which directs this operation. It also has the further function of indicating the level LPG in the gas tank, by progressive lighting 5 LEDs.

Polaris is easy to be installed, doesn't need connection of RPM signal and setting of the system, simple and quick, is managed by the special software supplied.

REDUCER VAPORIZER
Hercules is a mono-phase reducer, equipped with water heat exchanger, exit pressure compensation device and temperature and pressure sensors. Compensation permits the pressure change between the reducer exit gas and the suction manifold to be maintained at a constant level, in accordance with the variations in operating conditions. this involves an increase of the injection pressure in proportion with the engine load., guaranteeing an optimal result from the system for all power requirements . The purpose of the temperature and sensor pressures is to collect the main information regarding the physical state of the LPG and to transmit it to control unit which then makes appropriate modifications to the injection times.

ELECTRONIC INJECTORS
E.V.G is an electronic injector comprising two, three or four nozzles with an appropriate section (varying from car to car depending on cubic capacity), and an electromagnetic ignition coil/valve system that controls the opening and closing of the nozzles. It features an extremely rapid response(<1 ms), almost comparable to normal petrol injectors. Because of of this, POLARIS also allows for comfortable and optimal driving in every gear.

"The Polaris Sequential Injection System also contains all the other accessories like solenoid valves, copper pipes, rubber hoses, clamps, multivalve, airtight box and permanent tanks [cylindrical / toroidal], in addition to the above highlighted main components. Since the system as against the traditioanl mixer feeding system, is working on a MASTER [petrol ECU] / SLAVE [gas ECU] symbiosis, the tuning part is based on a highly sophisticated software."
