Toyota commissions Yamaha to develop hydrogen-fueled 5.0L V8; follow-on from Nov 2021 announcement

Toyota Motor Company has commissioned Yamaha Motor to develop a 5.-liter V8 engine for autos that’s fueled solely by hydrogen. In Japan, Toyota and different automotive-connected companies are about to begin out a collaborative exertion to extend the array of gasoline options for inside combustion engines.

We’re performing in direction of attaining carbon neutrality by 2050. At the very same time, ‘Motor’ is in our enterprise title and we appropriately have a strong enthusiasm for and degree of dedication to the inside combustion engine.

—Yamaha Motor president Yoshihiro Hidaka

In November 2021, the 5 organizations of Kawasaki Main Industries, Subaru Company, Toyota Motor Firm, Mazda Motor Company, and Yamaha Motor collectively declared they’d begin out conversations for conducting collaborative analysis into doable avenues for growing the assortment of gasoline selections for inner combustion engines within the quest for carbon neutrality. (Beforehand article.)


November 2021 hydrogen motor prototype.

On the announcement location, the V8 hydrogen motor revealed earlier talked about, which was designed by Yamaha for Toyota, was unveiled to most of the people. The system is based on the 5.-liter engine within the Lexus RC F luxurious exercise coupe, with modifications created to the injectors, cylinder heads, consumption manifold, and far more, and delivers as much as 450 hp at 6,800 rpm and a utmost 540 N·m of torque of at 3,600 rpm.

Hydrogen engines family the possible to be carbon-neutral while holding our ardour for the interior combustion engine alive on the similar time. Teaming up with suppliers with numerous firm cultures and areas of skills as completely as rising the quantity of companions we’ve is how we wish to direct the best way into the upcoming.

Hydrogen: not a stand-in for gasoline. Yamaha started producing a hydrogen engine for vehicles about 5 years again. Takeshi Yamada from the Advanced Exploration & Enchancment Heart’s Automotive Enchancment Part is a member of the hydrogen engine enhancement group and he began to notion the depth of doable within the powerplant because the challenge progressed.

I began off to see that engines working with solely hydrogen for gasoline primarily had fairly enjoyment, uncomplicated-to-use effectiveness traits. Hydrogen engines have an innately nice really feel that will make them fast to make use of even devoid of resorting to digital driving aids. All people who arrived to have a look at-travel the prototype auto would get began off considerably skeptical, however emerged from the car with a big smile on their expertise on the conclude. As I watched this, I began off to think about that there’s primarily monumental alternative within the attributes unique to hydrogen engines alternatively of simply managing it as an alternative to gasoline.

—Takeshi Yamada

An extra matter that Yamada and the crew worth within the improvement process is Kanno Seino, indicating sensual or exhilarating effectivity. Only one working example is the harmonic higher-frequency exhaust discover created by the engine’s 8-into-1 exhaust manifold.

It is a impediment we will sink our enamel into as engineers and I individually wish to pursue not simply efficiency but in addition a brand new entice for the inside combustion engine that the planet has nonetheless to see.

—Takeshi Yamada

Earlier this month, Yamaha introduced it should bolster its analysis and enchancment providers for powertrain applied sciences geared toward acquiring carbon neutrality, this type of as electrical motors and hydrogen engines, in the midst of the size of its new Medium-Phrase Administration Strategy (2022–2024).

This enlargement will set up in ranges quite a few new units, like electrical motor examination benches, hydrogen present units, and carbon-neutral gasoline storage tanks at Setting up No. 32, which was concluded on the firm’s headquarters earlier yr. After concluded, the ability will have interaction in a foremost place in making use of eco-friendly engineering steps for Yamaha options throughout the board.

In July 2021, the Firm reviewed the Yamaha Motor Group Environmental Put together 2050 initially formulated in 2018 and established a brand new goal of aiming for carbon neutrality all by means of all of its enterprise actions—together with throughout the on a regular basis residing cycles of its merchandise—by 2050.

Amongst these enhancements, Yamaha Motor established a goal of lowering Scope 3 CO2 emissions (emissions developed from the corporate’s worth chain, e.g., use of purchased objects) by 90% by 2050 in distinction to 2010. This enlargement of R&D providers will additional bolster the expansion of latest electrical energy strategies as successfully as speed up their implementation.
