The market for natural gas transformations of hybrid cars is rapidly consolidating in Italy, thanks to the development of technologies, the know-how acquired by the installers and greater awareness among users. According to trials, a hybrid vehicle converted to natural gas can emit 24% less CO2 than the same petrol/hybrid vehicle (data obtained by carrying out tests with PEMS – Portable Emissions Measurement System).
For this reason, Ecomotive Solutions and Autogas Italia (both subsidiaries of the Holdim group) have taken a further step forward in this field with the obtaining of approval by the Ministry of Infrastructure and Transport for Euro 6D Temp types of engines, also for natural gas configurations. This is the first approval in Italy, made possible also by the collaboration with Snam4Mobility, subsidiary of Snam, which promotes sustainable mobility with natural gas and biomethane.
This specific natural gas conversion kit is suitable for direct and indirect injection engines. The development was carried out on a Toyota C-HR 1.8 Hybrid; the hybrid/petrol + CNG bi-fuel system is currently the only one recognized by the Ministry of Infrastructure and Transport. The pilot vehicle was made available for this project by Snam4Mobility, and will become part of the company’s environmentally-friendly fleet.
The engine compartment houses a dual stage pressure reducer, an electronic control unit for the control and management of the CNG system, a rail with four CNG injectors. Moreover, in order to safeguard the original volumetric capacity of the trunk, a ‘tailor-made’ solution has been designed which provides for the housing of three 24 + 24 + 22 liter tanks allowing a variable range of 300-350 km based on the distances and the conditions of use of the vehicle.
The refueling point for the tanks is positioned laterally in the rear of the vehicle outside the bodywork. Regarding the performance, power test bench delivered the same values as the original petrol setting. On the road there were no changes in driving behavior.
