The Japanese have developed an internal combustion engine capable of running on four types of fuel (1 photo)
Toyota continues to develop new internal combustion engines in parallel with the development of electric vehicles. The concern's engineers have made a motor capable of running on gasoline, biodiesel, synthetic fuel or hydrogen. It is designed to work as part of hybrid power plants. 
The starting point was the engine of the racing Toyota GR Corolla. It runs on hydrogen, but it is not a design with electricity-generating fuel cells. Liquid hydrogen burns in three cylinders of a 1.6 turbo engine.
As a result of further development of technology, the new internal combustion engine can run on regular gasoline, biodiesel, liquid hydrogen, as well as artificially created synthetic fuels. At the same time, the level of harmful emissions is lower than that of conventional internal combustion engines.
The Japanese note that the multi-fuel engine will be 10–20% smaller in size, but more economical and powerful. Versions have been developed with a volume of 1.5 liters with and without supercharging, and 2.0 liters with supercharging. They are distinguished from mass-produced engines by lower torque, but electric motors in hybrid installations offset this disadvantage.
The exact technical specifications are kept secret for now. The new units just have to go through the necessary test cycle. It is assumed that they will meet the environmental requirements of Euro-7 class.
