Last September 3 - 4, 2018, a circuit test drive for the new Ninja ZX - 10 RR was carried out at the autopolis in Kyushu. From this magazine Hiroshi Maruyama of the main tester participated and checked the inside of a new 204 ps engine.
Large effect with finger follower which does not push the valve directly
It is the finger follower rocker arm that becomes the kimo of this power up. There is a seesaw type rocker arm with respect to the center point, but this is pushed by one side. In the system where the camshaft pushes the smooth part of the upper surface of the finger follower and pushes down the valve on the opposite side, the camshaft does not push the valve directly, pushing it off the center point, push down the valve. It is a mechanism to increase the lift amount, change the profile of the camshaft, and output the low speed and high speed by using this. With the conventional direct push type, it is possible to cover the entire area by using the finger follower, where the power is increased by only the width to secure the lift amount of the camshaft and the overlap, and it becomes high rotation type I can say that this time we can make power characteristics. With this, the ZX - 10R of this time is 3 ps up with a high rotation peak. It is the effect of the finger follower valve system that the low and medium speeds up to that are also up all over.
By using the finger follower as a lever, not only can the valve lift amount be increased beyond the actual cam crest height but also the mass of the reciprocating motion of the valve can be reduced by 20% compared to the conventional tappet direct striking type. As a result, the maximum output generated rotation has increased by 500 rpm.
Camshaft of the new 10R series. In the conventional direct pushing type, in order to increase the lift amount, it was not possible to raise more than the limit of the cylinder head other than increasing the cam crest. In the conventional type of ZX-10 RR, the head was partially cut to make it possible to mount a high lift cam for racing, but the new model can be mounted without machining the whole series.
Titanium connecting rod contributing to improvement of power and handling
In addition, another kimo is titanium connecting rod. Even if you take it compared to steel connecting rod, it is light. We can reduce the inertia mass when weighing 102 g, 4 units together and 408 g when turning with high speed rotation, while on engine braking it is possible to generate an inertial mass due to crank rotation and place a load on the front wheel It is said. In addition to becoming lighter it gains 1 ps up by alleviating friction and so on. However, originally, it is the titanium connecting rod that benefits the response to handling and acceleration / deceleration, and has been added to the ZX - 10RR = homolog model. In reality, I could also check the engraving of Panckel. The piston pin is made of steel, the piston does not change the compression ratio in particular, but its shape has been changed slightly to fit the new head.
The upper photograph shows the top of RR's titanium connecting rod and the bottom is STD or SE steel. The lower row shows the situation when it is compared, and from the image also the titanium connecting rod seems to be looking pretty light.
Funnel is compatible with full revolution range with 2 stages
Another one, the air cleaner box has also been changed. The suction port is rounded against the funnel of the complementary type, the medium low speed region sucks from the long complement type funnel, and when it reaches the high revolution region, it sucks also from the underlying clearance part and outputs the high revolution power . Although it was an ordinary funnel in the conventional model, the former model used this two-stage funnel. It has been adopted again for the purpose of lifting the medium and low speed range, again this 2-stage funnel specification was good for this engine. In addition, this time, the air filter adopts elements with less air resistance. Of course, for racing we use something with less air resistance.
Yamaha's YZF-R1 uses an electronically controlled variable funnel whose height changes according to the rotation range, but the ZX - 10R series adopts a two - stage system aimed at the same effect with a simple structure.
