Basic elements of the bus (body and connection terminals plate) are made of aluminum, whereas the nests plate that is located between them is made of plastics. Seals are made of rubber that is appropriate for working conditions of the element. Other elements are made of materials that were tested for resistance to LPG factors. Connection terminals (1, 3) are made of brass. Ending of feeder cables is equipped with AMP 282108 plug.

Bus is designed for sequential gas injection installations (fourth generation liquid gas installations) in vehicles equipped with gasoline engines. It assures a precise dosing of evaporated and filtered gas to inlet channel of each engine cylinder separately.

The produced injection bus is classified as 2A. It has a certification according to the ECE regulation 67.01 No. E6 67R- 014220.

Valve should be mounted in the shorter possible distance from the engine inlet channel. The shorter is the distance between LPG gas injection and gasoline injectors, the better would be the driving dynamic while using LPG gas. It should be assembled by means of two vibration absorbers located on openings (2). The aim of these absorbers is to minimize the influence of car vibrations. Position of bus assembly has no influence on its proper functioning. In order to assure proper functioning of the bus and in order to prevent gasoline injectors against damages, a filter of volatile phase has to be assembled. This filter is also offered by FACH S.A. As the gas inlet channel is manufactured as a open ended channel, its opening located on the opposite end to the inlet should be blocked with a stopper equipped with temperature sensor. In order to ensure proper functioning of injection bus, the gas reducer should be adjusted so that the gas pressure at the outlet is kept in the range of 0,095 – 0,105 MPa. For proper functioning of the injectors’ bus it is necessary to have a clean filtering insert. Hence, this insert is to be regularly inspected and replaced by new one if necessary / dirty.
