ARKANSAS, Nov 13 (Future Headlines)- Toyota Motor is set to participate in the ENEOS Super Taikyu Series 2023 Supported by Bridgestone Round 7 Super Taikyu Final Fuji 4 Hours Race with Fuji Niq Festival, showcasing its commitment to hydrogen-powered vehicles. The event, scheduled from November 11 to 12, will feature the #32 ORC ROOKIE GR Corolla H2 Concept, running on liquid hydrogen, and the #28 ORC ROOKIE GR86 CNF Concept powered by carbon-neutral fuel. Toyota’s participation underscores its dedication to advancing hydrogen technology in motorsports, with significant improvements made to enhance the performance, range, and efficiency of the liquid hydrogen-powered Corolla.
The #32 ORC ROOKIE GR Corolla H2 Concept, initially introduced in the 24 Hours Race in May, has undergone significant advancements. Toyota addressed challenges related to liquid hydrogen pump performance, focusing on achieving high fuel pressure stability for increased engine output. Improvements in pressure boosting performance and pump durability enable the liquid hydrogen engine to achieve output levels comparable to gasoline and gaseous hydrogen engines.
The liquid hydrogen-powered Corolla aims to achieve a longer cruising range, with a target of 20 laps per hydrogen fill-up in the upcoming race. Enhancements include improved accuracy in determining hydrogen tank fullness, reduced boil-off gas through minimizing heat entering the tank, and optimized fuel injection during partial throttle conditions.
Toyota prioritized safety and security while identifying components that could be made lighter without compromising integrity. Adjustments in factors such as thickness and the number of parts resulted in a weight reduction of 50 kg, bringing the vehicle weight to 1,860 kg from the 1,910 kg recorded at the Autopolis race.
- CO2 Capture Initiative
In a trial initiative, Toyota will install a CO2 absorption device at the air cleaner inlet, complemented by a CO2 separation device utilizing engine oil heat. CO2 separation will occur beside the air cleaner, capturing separated CO2 in a tank filled with an absorbent developed by Kawasaki Heavy Industries, enhancing CO2 capture efficiency. This initiative aligns with Toyota’s commitment to environmental sustainability and reducing the carbon footprint associated with racing activities.
Toyota is conducting on-road feasibility testing in Australia, installing a hydrogen engine in a commercial HiAce for real-world applications. By participating in the Super Taikyu series and on-road testing simultaneously, Toyota aims to refine hydrogen engine technology further, advancing it toward practical applications.
Participation in the ENEOS Super Taikyu Series 2023 allows Toyota to leverage competitive racing environments for technology development. The series serves as a proving ground for advancements in hydrogen-powered vehicles, driving innovations that contribute to both motorsports and the broader automotive industry.
