The adoption of sequential gas injection for petrol engines has various advantages:
Petrol engines are controlled by an electronic control unit (ECU) which, depending on a number of parameters (such as the air and engine temperature, the quantity of air in the intake duct, engine speed and timing) determines the fuel injection time instant by instant.
The main types of original injection systems for petrol engines are:
To convert an injection engine from petrol to LPG/Natural Gas it is necessary to use a second electronic control unit alongside the original ECU. The gas control unit manages the gas fuel supply, optimising engine performance and subsequent emissions.
AEB designs and creates electronic control units for LPG/Natural Gas conversions that can be used on all the engine types described above.
