What type of LPG conversion
While many of the automotive gas systems installed in the early 1990s remain the classic mixer type systems, they are being permanently replaced by more efficient multi-point systems, often incorporating sequential injection technology.
This is necessary for the LPG industry to keep up with the major advances being made by car manufacturers in developing vehicles that comply with the latest Euro III/IV /V AND IV emission standards for petrol engines.
The relatively crude mixture control of the early single point systems is no longer able to achieve the low emission levels required for today’s much cleaner petrol engines and also causes many engine control light problems on all new vehicles equipped with EOBD (On-Board Diagnostics) mixture control systems. Multi-point systems offer other crucial advantages: No performance restrictions.
Installing a mixer on the throttle body with single-point systems, significantly reduces the volume of air that can flow… A calculation of a typical mixing ring for a Range Rover 4.6 confirms a massive 70% reduction in aperture area! with the risk of costly blowback.
Even the best installation of single point technology cannot guarantee that the system does not backfire.
The principle of mixing gas and air at the throttle body means that the plenum and intake manifold will also be loaded with the explosive mixture en route to the cylinders, not just the air the engine was designed for. All it takes is a vacuum leak in the manifold or a spark plug or HT lead problem to cause the system to backfire, often resulting in damage to the air filter housing or the vehicle’s air flow meter.
We believe that it is our responsibility to provide you with sufficient information to make your own decision on the choice of an LPG kit with a high-tech sequential multipoint injection system, such as the Zenit kits sold by the AIR LPG representative in France and by AG Centrum, the manufacturer of LPG kits in Poland.
We will be happy to guide you to an installer in the AIRGPL network to install the system you choose. Do not hesitate to contact us by email email@example.com.
