We're not advertising for any particular supplier here, what this is, is a description of the self-installation of a system with valves for a four-cylinder and, despite the somewhat larger tank, for less than €1000. The injectors, because of the blow-in injection, are distinctly larger than those normally used for petrol engines, they are however, installed in the same place, of course somewhat offset, since the petrol system will, as before, still be used.

Mostly the entire inlet port together with the cable harness and the fuel line must be removed to be able to set the drill holes. A perfect sealing here has top priority, otherwise there is the threat of unwanted air. This is taken care of by a sealing compound, thus the inlet, together with the additional injectors, can be mounted again, on condition that also the additional lines have been conscientiously laid.

Of course, the position of the injectors is never ideal but because gas is flowing and not petrol, the mixing is very much simpler. For the gas to flow in, it requires an evaporator, which, in the meantime, is much smaller than it was before. It's no problem to find somewhere to mount it. After the lines have been laid and the evaporator integrated into the cooling system, the installations in the engine compartment are wound up.

For those who install the control device for the LPG equipment in the engine compartment, because of the short connections to the inlet nozzles, a bit of work still has to be done. In any event, here it is protected from water and it can also be well cooled. Now we finally go to the rear to inspect the spare-wheel recess. Of course, a tool which can cut a clean, round hole and is not very expensive, is an elegant solution. It serves, when properly sealed, for the gas-tank mounting and also the laying of the lines.

Something brainpower is for laying the gas pipeline necessary covered with protective cover at the lowest point of the body. Also the filling valve could, instead of being mounted onto a metal gusset in the open, be perhaps next to the filling cap, behind a (lockable) cover. Electric cables should certainly be laid in the interior of the car. Apart from these few comments, the work is now coming to an end.

We would prefer a completely closed tank without an internal hollow for the pressure reduction valve and would place this in a protected space in the luggage compartment. Apart from that, on the the driver's side, one must be able to switch over from gas to petrol operation and a little information from the engine management is necessary, e.g., an RPM-signal. Fortunately, in the package, there are the cables and the software needed to ensure the proper setting up of the equipment. 08/12
