Experimental Toyota Corolla with hydrogen internal combustion engine successfully completed 24-hour race
Toyota has announced that its experimental Corolla hydrogen car has successfully completed the 24-hour Super Taikyu race.
In this case it is the modernization of the machine that is of interest. The fact is that, unlike the same Toyota Mirai or other serial (and not only) hydrogen cars, where hydrogen is used to generate electricity, and it is the electric motor that drives the car, a car with an internal combustion engine, which was adapted for combustion, took part in the race. hydrogen. Toyota’s goal was to demonstrate the viability and safety of this approach.
The Corolla began to be built just three months before the start of the race, so Toyota made the most of the existing components. The 1.6-liter engine was taken from the GR Yaris, reworking the fuel supply, injection and ignition system. The fuel tank, delivery system and fuel management system were taken from the Toyota EV Mirai.
The main problem for the engineers was the very high combustion temperature of hydrogen. The team ended up converting the engine to direct injection using an injection system developed by Denso. As for the power, there were not so many losses compared to the gasoline engine, but the exact data was not named.
As a result, the car successfully completed the race, although, for example, it required much longer stops to refuel. The process lasted six to seven minutes, and in total the car took 35 refueling to cover 358 laps or 1634 km.
It is also worth noting that the head of Toyota, Akio Toyoda, was personally driving the car.
