November 27, 2020. The Irizar Group incorporates compressed natural gas (CNG) and liquefied natural gas (LNG) to its range of technologies. The vehicles have a range of up to 500 km in the CNG version and double in LNG technology.
In this way, it expands its range of efficient and sustainable products and technological solutions in terms of operations, and becomes the brand that includes all the technologies currently on the market. From integral and conventional coaches with Euro 6D diesel, HVO, B100 combustion engine and natural gas or biogas, to buses and 100% electric vehicles, to coaches with parallel hybrid technology in their class I and class II models for urban and interurban services.
The first vehicle equipped with this technology is the Irizar i4 class II model, a versatile and ideal coach as a metropolitan, commuter, school or business coach. It is an Irizar i4 version H, 12,920 meters long on a Scania K320 EB 4X2 E6D CNG chassis.
With an approximate total weight of 750 kg, it incorporates 4 longitudinal cylindrical tanks type IV CNG, with a total volume of 1260 dm3 and an approximate gas capacity of 240 kg. However, depending on the needs of the operator, it can be equipped with an additional tank to increase autonomy. In addition, it includes a filling panel with two gas outlets and a pressure gauge. The integration of the storage tanks preserves the aesthetics and aerodynamics of the vehicle and allows it to perform the same type of service as a diesel equivalent with optimum road holding and maximum safety.
The units are equipped with the same air conditioning system as diesel vehicles. The height of the headliner, the interior luggage racks and the luggage compartment capacity are the same as the diesel version.
The driver has a gas control screen to comply with all safety protocols. It allows drivers to detect leaks and monitor the start-up of the water additive aerosol fire suppression system.
These vehicles comply with Regulation R66.02 even with 700 kg of extra weight on the roof and with the thermal safety and mechanical safety protocols, according to Regulation 110.
