Maruti Suzuki, India’s largest car maker, unveiled its CNG engine technology, “intelligent-Gas Port Injection” (i-GPI) on five popular models: SX4, Eeco, WagonR, Estilo and Alto. The CNG models span entry level cars, compact cars, sedans and MPV segments and are being launched in Delhi NCR, Mumbai and Gujrat.

The i-GPI technology is a Dual ECU (Engine Control Unit) technology, which delivers accurate amounts of gas to the engine, ensuring improved and consistent performance under various driving conditions. The i-GPI technology uses separate injectors for each cylinder. Based on inputs from the ECU, metered CNG quantity is injected to the engine through gas ports. The quantity of CNG required for different driving conditions is controlled by the dedicated ECU, leading to more efficient fuel usage.

i-GPI ensures more power compared to retrofitted CNG vehicles and offers a peppier ride experience at par with that of a gasoline-fuelled engine, while achieving high fuel efficiency at the same time, the company says. Maruti Suzuki CNG vehicles pass through all the quality checks, processes and systems similar to a regular car manufactured at Maruti Suzuki plants.

As the CNG technology is factory fitted the customers will enjoy the full warranty benefits including extended warranty.

While working on the new CNG technology, Maruti Suzuki engineers focused on critical aspects of safety, reliability and performance.

The Government of India has committed to developing the infrastructure and network of the CNG stations across the country, in support of its goal to reduce the dependence on import of fossil fuels. With the discovery of large gas reserves in the country the network of CNG supplies is set to expand rapidly in near future.
