Toyota Flanders／Nissan Hackers： Who is worth the money？ be clear／manifest at a glance

I have seen a detailed comparison between Toyota and Nissan from the outside to the inside. So what about the engines of these two cars? What’s the difference between CVT gearboxes? Today we will open it for everyone to see!

engine

Flanders is equipped with a 2.0L self-priming four-cylinder engine, which is a classic M20 series with a maximum power of 126kW and a maximum torque of only 205nm.

Nissan hacker is equipped with a 1.3T turbocharged four-cylinder engine, model HR13, with a maximum power of 116kW and a maximum torque of 270Nm. This engine was actually developed by Nissan Renault in cooperation with Mercedes-Benz, so it can be seen in Class B and Nissan Renault cars.

This M20 engine is made of aluminum alloy block from top to bottom, and adopts Toyota D-4 mixed injection technology, which can be compatible with manifold injection and direct injection in cylinder at the same time, and the thermal efficiency of the whole engine is as high as 40%.

This M20 engine adopts laser side skirt piston, which improves the oil retention and scratch resistance. In addition, the cylinder is made of diamond-like carbon electroplating material and coated by physical vapor deposition technology to achieve the effects of high hardness, high elasticity, high inertia and low friction.

Hacker’s engine is also an all-aluminum cylinder from top to bottom. What is different is that this engine adopts a triangular cylinder head, which makes the exhaust gas closer to the engine center. The compact design makes the engine lose about 3 kilograms. In addition, the cylinder bore coating technology of Nissan’s new generation Nanoslide is adopted in the cylinder body, and the coating materials such as iron or carbon are instantly melted by high-voltage arc and evenly sprayed on the inner wall of lightweight aluminum alloy cylinder, so that the mechanical friction loss of the cylinder is reduced by 50% compared with that of the traditional gray cast iron cylinder liner, and at the same time, it has very high wear resistance.

In addition, the engine of hacker also uses an electronically controlled wastegate valve, which can change the opening pressure of the bypass valve. The later the opening time of the solenoid valve, the greater the boost pressure and the higher the power torque of the engine. In fact, this is how many engines adjust their high and low power. On the engine external characteristic curve, the speed at which the torque curve begins to decrease is the time for the bypass valve to open.

Looking at the exhaust part, Flanders uses a common exhaust manifold. Hacker is the latest integrated exhaust manifold. When the car is cold, the high temperature of the exhaust manifold can quickly heat the coolant, and when the engine is under high load, the coolant can also cool the exhaust. When the exhaust temperature is lowered, the pollutant content in the exhaust gas will be significantly reduced, which will help the engine meet more stringent environmental regulations. At the same time, because the integrated exhaust and cylinder body are almost integrated, the weight of the engine can be further reduced by about 3 kg.

The particle catcher in Flanders is far away from the engine, and the temperature is relatively low, which is not conducive to burning particles and is easy to block the particle catcher. The hacker’s particle catcher is close to the exhaust end of the engine, which can reduce the particle catcher by using the high temperature of the exhaust, making it difficult to block.

continuously variable transmission

Both Flanders and hackers match CVT gearboxes, but after disassembling, they are not the same.

Flanders use steel belt structure, and most CVT gearboxes are like this at present. The supplier of this steel belt is Bosch, which consists of numerous wedge-shaped steel sheets connected in series through two flexible steel belts. The biggest advantage of steel belt drive is low cost, and it can also reduce the size of gearbox. However, the disadvantage is that the maximum torque of power output will not be very large, and "slipping" may occur during rapid acceleration, and the instantaneous power transmission efficiency will become low. Moreover, it is sensitive to high temperature and low temperature, and the probability of steel strip fracture is relatively high.

Although hacker is also a CVT gearbox, it is no longer the previous Nissan CVT, and the steel belt drive is replaced by the steel chain drive of Schaeffler, Germany. Steel chain is countless perforated steel sheets connected by chain, and its strength and durability are much stronger than that of steel belt. The friction with the bevel wheel will be greater, and it can bear a large torque of 450 Nm, and the power loss during rapid acceleration is less, and it is not easy to "slip". However, the steel chain has high cost and relatively large volume, but it is more "anti-manufacturing", so it often appears in some cars that pay attention to power. For example, Audi A4 and Subaru XV all use CVT gearboxes driven by Schaeffler steel chain.

The CVT gearbox of Flanders uses Toyota’s "Drirect Shift-CVT" technology, that is, a gear is added in front of the CVT transmission wheel. When starting, the gear can be directly driven to avoid the loss of power due to the "slipping" of the starting steel belt, which is also a remedy for the weakness of its CVT gearbox.

Because the CVT of Fenglanda is driven by steel belt, it can’t output large torque, so only a mechanical oil pump is equipped to spray and lubricate the interior of the gearbox. The hacker uses steel chain transmission, which needs better heat dissipation, so the electronic high-pressure oil pump is used to provide higher oil pressure.

summary

Buy who? be clear/manifest at a glance

Through the dismantling of Toyota Fenglanda and Nissan hacker, Toyota is still the Toyota that pursues "enough is good". On the other hand, Nissan hackers are striving for change, "leaving Asia and entering Europe", using a higher-level Loulan platform, using a large number of aluminum alloys to lose weight, using a brand-new 1.3T turbocharged four-cylinder engine and using a steel chain CVT gearbox. To tell the truth, it’s really unexpected that Nissan can make such a change!

Then, how do you choose these two compact joint venture Japanese SUVs with similar prices? If you just want to buy a cheap, home, not too much pursuit of driving and motivation, then Feng Landa can do it. And if you want a young and fashionable appearance and high configuration, you have a certain pursuit of power and driving control. That’s obviously more value for money!(The conclusion of the measurement data in this article and the video is only responsible for this car, and the measurement data is responsible for the publicized experimental method. )
