When it comes to professional 2nd generation auto gas installations, their operating principles are similar to those of the first generation. The significant difference, however, can be seen in the use of electronics and design, since the second generation of the system is not applicable to carburettor engines. In addition, the 2nd generation gas installation replaces the adjusting screws on the conduits between the regulators and the mixers with a special throttle valve that is most commonly controlled by the stepper motor.

Electrical installation in the 2nd generation autogas system

It is worth mentioning that the 2nd generation gas installation has a much more extensive electrical installation. The second generation contains not only fuel selection switches, but also an electronic control unit, which can be used to control stepper motors and special emulator of lambda sensors and injectors.

What are emulators?

Emulators are nothing more than modern electronic circuits, which primary task is to generate electrical signals to deceive the gasoline controller. Emulators are designed to imitate the correct operation of petrol injectors and lambda sensors only when the car engine is powered by LPG. Without the help of emulators, the petrol driver will always generate errors so that the engine will not be able to work properly.

Electronics in second generation of autogas installation

The main purpose of the autogas installation electronics is of course to determine the composition of the fuel / air mixture, using the appropriate signal transmitted by the lambda sensor. Thanks to this mechanism (unlike 1st generation) the correction of the fuel-air ratio can be carried out on a regular basis at the time. Gas controllers are responsible for only the composition of the mixture. Gas controllers do not respond in turn to the characteristics of the entire gas supply system. The mixer and the regulator are responsible for that.

Who is the 2nd generation autogas installation for?

Second generation gas installations are primarily designed for engines that are equipped with single or multi-point petrol injection, lambda sensor and special catalyzer. Second generation autogas installation is a much more advanced system since the first generation and should not be used in carburettor engines.
