337km / h world record breakthrough! “Ninja H2”

A

KAWASAKI sent Ninja H2 to participate in the Bonneville Speed ​​Week (Bonneville Speed ​​Week) held in the United States in 2018, and successfully set the world’s fastest record of 337.064km / h on the P-PB1000, which has strict conversion regulations.

A

Below we will interview Shi Congxian, the head of R & D for Ninja H2, and talk to him about the challenges and the selling points of the 2019 Ninja H2.

ninja-h2-02 Congxian:The head of research and development of Ninja H2 / H2R, whose technology is far beyond the scope of motorcycles, and even spans into other departments such as aerospace technology and gas turbine engines, is one of the heroes who helped Kawasaki Heavy Industries lay the foundation of superb technical standards.

Set the fastest record for general cars with overwhelming horsepower

“Ninja H2 has been four years since its debut in 2015. In 2019, the maximum horsepower has been greatly increased to 231ps. From the track, the maximum horsepower of Ninja H2R is 310ps. You may think that we are just The horsepower is lowered, but in fact we have made changes in many details, and the basis of these technical knowledge is from the Ninja H2 SX, a brother car launched later.

A

As everyone knows, because Ninja H2 SX is a wagon model, it must take into account both horsepower and fuel consumption. Therefore, we developed a balanced supercharged engine at the time, and then it became more practical after improvement. The high-efficiency technology is also fed back to the Ninja H2’s power supercharged engine.

A

Among them, the most obvious one should be the intake header made of aluminum alloy. Although the current model changes the intake air collector into a fan shape to improve efficiency, the 2019 style has a horn-shaped diffuser inside to make the intake air smoother, because if the supercharged engine exhausts the gas at one breath When expanding in the expansion chamber, turbulent flow will occur and the efficiency will decrease.

A

However, KAWASAKI suppresses the occurrence of turbulence by installing a diffuser, so it can generate horsepower more efficiently. In fact, torque above 7000 rpm will increase, and after improvement, people can directly enjoy the advantages of supercharged engines. Ninja H2’s sense of extension at high speeds is also very different from other cars, and the overwhelming sense of acceleration has also become more obvious. “

The Ninja H2 participating in the Bonneville Speed ​​Week has only changed the dashboard display, speed limiter and tires. The other is basically the specifications of the 2019 version of the commercial version, which means that KAWASAKI is the original specification To participate; to be able to buy a commercially available car with almost exactly the same specifications is definitely something the knight dreams of.

A

“In order to be able to measure the performance of this specification earlier, we challenged the Bonneville Speed ​​Week for the third time with the company’s internal team Team 38 in August last year (2018).

A

In the past, in order to understand the possibility of the car models developed by myself, we chose the special track model Ninja H2R to be proud of the strongest specifications, but this time we are to win the title of the fastest car model on the market, so we sent 2019 The annual Ninja H2 participated.

A

We signed up for the most demanding P-PB1000 grade, and set the world ’s fastest record at 209.442 miles per hour (337.064km / h). In fact, although the speed on the first day of the test exceeded 210 miles per hour, on the second day, the tire slipped due to dew, so the performance fell to 207 miles per hour, which also caused us to regret the average record results.

A

Although this game requires absolute horsepower, it is not simple at all, because it will be affected by the salt lake pavement and wind speed during the game, so there is no way to walk exactly as we think.

A

Nonetheless, being able to set a world record with almost no difference from the commercially available version is definitely the most happy result for us R & D personnel. “

A

ninja-h2-04 In order to prove the performance of the car models that he personally participated in, the R & D driver Yamashita (right) and others took Ninja H2R in the Bonneville Speed ​​Race in 2015 and 2016 under the name of Team38 (in 2015, because the event was suspended, so they participated instead Mojave Mile), in 2018 it was challenged with Ninja H2.
ninja-h2-05 The Ninja H2 / H2R equipped with a supercharged engine developed by innovative technology, in addition to being awarded the Technology R & D Award at the 69th Automobile Technology Association Award, also won the Technology Award of the Japanese Combustion Society last year, and was also received in the academic field. Recognition.

The ability to connect smartphones opens up new possibilities

“The selling point of the 2019 style is that it uses a full-color LCD screen. This part is the same as the Ninja H2 SX. Except for a part of the display content, it is basically the same. And the most attractive thing is the ability to connect with wisdom. The APP program “RIDEOLOGY THE APP” for mobile phones is now available.

A

Ordinary people may think that it can only display incoming call and new letter notifications on the dashboard, but KAWASAKI’s great thing is that it can display and record the driving information of the electronic control system. Google Maps allows riders to check their riding routes at any time, and at a glance when and where they have been riding from.

A

Although the 2019 model replaces the front wheel brake calipers with small and light Brembo brake calipers and improves it to the best car for street riding, even the hydraulic pressure of the brakes can be displayed. It seems a bit too much? (laugh)

A

Although the APP program that can connect to the mobile phone is not yet at the level of the track GPS data analysis tool, I believe that it will definitely be upgraded to the same level in the future.

A

Although this year’s car has been changed even with the ECU, the main change is the function of connecting the APP program, collecting information through the vehicle’s CAN communication and transferring it to the smart phone, this user interface will become a major in the future The essential. Although it is now only seen as a way to master the status of motorcycles, if we can use AI artificial intelligence to communicate with motorcycles in the future, riding a motorcycle should become more fun and interesting.

A

Every Ninja H2 / H2R order is carefully crafted one by one, so I am sorry to let everyone who booked the car wait so long, but Ninja H2 / H2R will also continue to use the self-healing paint (Highly Durable paint ), So you do n’t have to worry about small scratches and scratches, try to enjoy the ride! I hope to have the opportunity to continue to develop the supercharged engine that everyone expects in the future, so that its charm will continue to spread. “

Improve the intake air collection tank, etc., to achieve the third generation of 231ps maximum horsepower

ninja-h2-06

A

Ninja H2, which came out with a maximum horsepower of 200ps in 2015, although the horsepower in 2017 only rose to 205ps, but in 2019, it was overwhelmingly improved to 231ps. The technical knowledge gained by the supercharged engine has changed the intake path to a more efficient shape, changed the material of the air filter element, and increased the protrusion of the spark plug electrode by 0.1mm.

A

ninja-h2-07 ▲ Adopt the same shape of Ninja H2 SX aluminum alloy air intake plenum, also equipped with a diffuser to suppress internal turbulence, so that the exhaust gas becomes smoother.

A

ninja-h2-08 ▲ Since the 2017 model, the self-healing paint (Highly Durable paint) has been used. Small scratches such as steel brushes can also be repaired independently.

A

ninja-h2-09 ▲ KAWASAKI’s own developed impact-resistant paint, minor scratches can be repaired automatically in just one day, so that the owner can always have a beautiful silver mirror coating.
