Continuous improvement of the efficiency of internal combustion engines and the use of renewable fuels are essential to achieve carbon neutrality by 2050.

Companies are developing new engines that maximise the potential of internal combustion engines while seeking further improvements in fuel efficiency and emissions, with a view to combining this with electrification. What is it like to discuss newly developed engines and the latest technology with all the gasoline and diesel engine engineers in one place?

In petrol engines, Suzuki is developing a 1.2-litre three-cylinder engine for the new Swift, while Subaru is developing a 2.5-litre engine for the next-generation hybrid with the new Crosstrek. Nissan is developing a V6 twin-turbo engine for its new flagship SUV, and Toyota is developing a hydrogen engine for Super endurance racing.

In diesel engines, Mazda is developing a CNF diesel engine with racing output for use in Super Endurance vehicles, while Yanmar Power Technology is developing a new 6GY135 series diesel engine for marine use, and Mitsui E&S is developing a large two-stroke engine for marine Mitsui E&S is developing large two-stroke engines for marine use.

In addition, Hyundai Motor Company of Korea is developing a combustion system for future SUVs for its new hybrid-only 2.5-litre TGDI engine.
