EG INJECTO DUO is a sequential gas injection system for cars with 3-cylinder and 4-cylinder engines with the so-called dual petrol injection system, i.e. having both multi-point indirect (MPI) and direct (DI) petrol injection.

The gas is fed to the intake manifold using 3 or 4 gas injectors depending on the number of cylinders in the vehicle's engine.
The innovative auto calibration and mapping algorithm enables quick and intuitive system tuning in a manner similar to the calibration of the standard EG INJECTO 48.4 system. When the system is correctly tuned, when driving on gas, the transitions between changing petrol injection strategies are imperceptible, while maintaining the vehicle's performance as when the engine is fuelled with petrol.

• The oscilloscope built into the controller allows for quick identification of input signals and verification of the correctness of the connections made
• The system consists of two controllers connected to each other by a communication cable: the EG INJECTO 48.4 DUO gas injection controller and the EG INJECTO 24.4 MPI indirect injection system emulator, which enables correct emulation of the MPI petrol injector signals when the engine is running on gas.
