Sequent Direct Injection 2.0

Sequent Direct Injection 2.0 is the system BRC developed for converting to gas the latest generation petrol direct injection vehicles. The gas is injected into the intake manifold while petrol is directly injected into the combustion chamber, allowing to benefit from the easy installation typical of Sequent systems and use the same mechanical parts. Main components include gas ECU with specific software for direct injection management and IN03 electro-injector that accurately manages the injection to increase the gas system performance in terms of both driveability and reliability.
