VSI is an abbreviation for “Vapour Sequential Injection”. The VSI-CNG system is the most advanced CNG system available on the market. With the VSI-CNG system CNG Interstate strives for optimal emission and cost reduction.
The VSI-CNG system is developed in close cooperation with Keihin Corp. of Japan, one of the world’s leading injector manufacturers and a name that stands for OEM quality and reliability.
The VSI-CNG system is fully integrated by way of a “master – slave” method with the vehicle ECU, making it (E)OBD compatible, therefore signal emulation is not required.
The key components of the system are all of OEM quality and specially designed for CNG applications. All components comply with the strictest regulations and certifications, therefore the system and its components are R110 and ISO 15500 homologated. The installation of the components is very easy due to the compact design of the components.
The specially dedicated diagnostic software is unique and enables fine tuning the VSI-CNG system for optimal emission reduction. By means of the specially developed Timing Optimizer (PTO) it is possible to decrease the power loss to a minimum.
For the storage of the CNG there are different cylindrical tanks available.
