Under the Bonnet: Technical Aspects of Conversion
Here is some basic information and pictures as to how the Etagas system is installed in to the engine bay of a Renault Laguna 1600 16v.
Tartarini Etagas Pressure Regulator
A small compact pressure regulator is easily fitted into the tight engine bay of most modern cars.
This unit controls the pressure of gas being supplied from the gas tank
under its own pressure and regulates the liquid gas down to vapour against
vacuum created in the inlet manifold.
A durable waterproof alloy case allows the ECU to be mounted in the engine bay and with all the wiring sheathed in black, so the installation looks professional and tidy.
Rapid processing of signals from the various engine sensors allows the Etagas system to adapt to all driving styles and road conditions encountered.
The Etagas ECU acts in the same way as the modern day petrol
ECU in the case of an accident the Etagas system will shut down all supply
of fuel from the LPG tank; the same process as employed on modern day
Tartarini Etagas Distributor
Fuel is then adjusted by the Etagas ECU using the fine trim stepper motor of the Etagas distributor before allowing the gas under pressure to be injected into the engine inlet manifold in just the right amounts and at just the right time.
Due to such small amounts of gas being injected the risk of an engine
backfire is eliminated resulting in smoother running and better engine
Special hoses are used with specific clips to ensure a good seal to the nozzles and easy routing of the hoses.
This procedure is always best done with the manifold removed and on the workbench.
A simple on the road calibration process ensures that the Tartarini Etagas system is calibrated perfectly to each vehicle before final hand over to the end user.
