Japanese brands seem to be clear that the efficiency of their new generation of motorcycles would go through the use of a turbo. The new E-Turbo engine This theory confirms and, in addition, the firm of the fingerboard would go one step further in this field, approaching the technologies that we can currently find within the automobile sector.
The purpose of the Japanese brand e -urb engine is clear: Increase benefits, reducing emissions issued and significantly improving the operation of the system itself. We refer to the entrance delay presented by these equipment when we work on a motorcycle we talk.
E-Turbo engine: one step further in technological terms
Following the latest technological innovations within the two-wheeled sector, those referred to the use of a turbo system in a motorcycle engine, it seems that Yamaha, with its newly patented e -urb engine, is clear what the way will be to go in the coming years, at least if we want to continue using the combustion engines to use.
As we all know, Honda displayed all its technological arsenal, on the occasion of the celebration of the last EICMA 2024, presenting the world its new V3 engine equipped with an electrical compressor. We talk about a four -stroke mechanics and 75 ° equipped with an electrical compressor aimed at offering a significant increase in low and medium revolutions, regardless of engine RPM.
For its part, Yamaha has been working on this type of technology for several years. Proof of this is the registration of the different patents related precisely to the addition of a turbo system in one of its mechanics. Already in 2017 the brand surprised us with one of these documents where two supercharging options were announced, both developed on the basis of a Yamaha MT-09 but with a bicylindrical engine such as MT-07.
By 2020 we asked ourselves: When will the New Yamaha Turbo arrive? The objective was evident: increase power and torque with contained emissions. In the images that we published then, the design of the lateral shots, certainly bulky to hide the Turbo Intercooler, as well as the water radiator located very low and near the ground.
Already in 2022 Yamaha returned again with the registration of a new patent related to the latter. While the registration drawings were based on an MT-10, the propeller used was clearly a CP3 tricylinder engine like the one that equips the Yamaha MT-09. Likewise, this technology was focused on being used in a sports car with a 2 to 4 cylinder engine, combined with a turbo or supercharger.
The latest information related to this issue comes to us by Cycle World and the always well informed Ben Purvis. The detailed plans presented by Yamaha in the patent registry show us an e -urb engine equipped, in principle, with an electrically assisted electrically similar electronic turbocharger to that used by some modern cars. Marks such as Garrett and Borgwarner are pioneers in the development and manufacture of this type of technology.
The essential idea is to improve the delay associated with conventional turbochargers. To do this “They add an electric motor to rotate the turbo and generate supercharging even when the exhaust pressure is not enough. This means that there is no delay, since the supercharging pressure is available to any regime or opening of the accelerator”as detail from Cycle World.
On the other hand, the design of this E-Turbo engine advocates a minimalist approach, trying to reduce the size of the equipment to use condensers instead of batteries, a high voltage electrical system being vital. In this case, cars usually have 48 V, for the 12 V we find in motorcycles. Finally, Yamaha also affects the need to maximize the system’s own installation.
Both the wiring and the sleeve system that would be specified to give life to this new e -urb engine, would be the lowest possible size. The weight and compact reduction of the set is one of the most relevant aspects in this type of technological displays. All this combined with a custom motor management to make the maximum performance to a propeller of this style.
