The adoption of sequential LPG/CNG injection for petrol engines has various advantages: optimal fuel dosage achieving mixtures with the correct stoichiometric ratio, excellent fuel consumption, reduced pollutant emissions, improved performance.

Petrol engines are controlled by an electronic control unit (ECU) which, according to a number of parameters, determines instant by instant the duration of the fuel injection.
The main types of original injection systems for petrol engines are:

  • Indirect injection systems (Port Fuel Injection – PFI) featuring petrol injectors upstream of the intake valves;
  • Direct injection systems (Gasoline Direct Injection – GDI/Fuel Stratified Injection – FSI) featuring injectors located in the combustion chamber. This provides an increase in performance and a reduction in consumption and emissions. To convert an injection engine from petrol to LPG/CNG it is necessary to use a second electronic control unit alongside the original ECU.

AEB ECU manages the alternative fuel supply, optimizing engine performance and subsequent emissions. AEB Alternative Fuel Electronics designs and produces electronic control units for LPG/CNG conversion that can be used on all the engine types described above. Beside the traditional sequential injection systems for MPI petrol engines, AEB Alternative Fuel Electronics has designed a new injection system for light-duty Diesel vehicles (12V).

The new system is based on the dual-fuel concept which means that engines can use Diesel and LPG/CNG at the same time.

These systems do not require modifications to the Diesel engine which keeps its own functional features. Matching a positive pressure regulator for LPG or CNG and an injector rail (up to 4 cylinders) with our dedicated dual-fuel ECU, we can convert OBD or non-OBD Diesel engines equipped with an electronic or mechanic pump.
