Alisei Direct Kit 4 Cylinders

The Alisei sequential injection system is based on a physical model software structure, helping to calculate gas injection times and to optimise their value under any engine running condition. These calculations are completed and made more effective by information on the engine RPM, gas pressure, gas temperature and water temperature, used to physically modify gas injection times.

The water temperature probe installed on the regulator sends a petrol/gas flow signal after engine start – which, among other things, is a function of the time elapsed after engine start and of engine RPM. The system also includes troubleshooting features and automatically switches to petrol in case of faults (switch-back), storing the component fault to the system memory. Control units available in two versions for 2-3-4 and 5-6-8-10 cylinder engines.
