NH3 engine: the car that runs on ammonia

The GT86-R Marangoni has been fitted with the NH3 engine system, offering dual fuel supply. The car can in fact run on petrol, as originally equipped, or alternatively use ammonia stored in a separate rank. The NH3 design has been developed by Bigas International, a company that for more than 40 years has been focusing on the use of alternative energy sources. The system uses a special pressure reducer, called RI21JE, and a special control unit to make sure that all safety and reliability requirements involving the use of ammonia are met.

This system completely eliminates fine dust particle emissions and significantly reduces CO2 emissions. The trials completed by BIGAS International as part of the Savia project analysed every aspect relating to compliance with current safety and pollution standards, testing the effectiveness of the solutions adopted on different prototypes over extended periods.

Ammonia has a higher energy content per kiilogram than petrol, and is consequently an excellent source of energy. Industrial production costs are the same as petrol, however a wider variety of raw materials can be used to make it: coal, natural gas, water, in theory anything that contains hydrogen, carbon and nitrogen can be used, albeit with different yields. Storage and transport are similar to LPG, while the power delivered by the engine is the same as for petrol.

Tyres: Marangoni M-Power EvoRed

For the Toyota GT86-R, Marangoni presents “M-Power EvoRed”, a special set of flame-red 19” tyres. For this experimental version, Marangoni Tyre has developed a highly-ecological tyre, based on the standard M-Power, the maximum in Marangoni technological evolution and applied research.

By using third generation functionalized polymers, designed specifically for better interaction between silica and polymer, and the introduction of innovative experimental nanomaterials as more effective alternative fillers to carbon black, M-Power EvoRed has managed to achieve class B rating for rolling resistance and class A for wet braking. These two values, outstanding for ultra-high performance tyres, confirm the efforts made to ensure lower fuel consumption and increased safety that, together with maximum driving pleasure, are the focus of Marangoni’s main product development guidelines.
