Turbocharger technology seems to have been dominated by European depot for many years? Japan car factory stick to the natural aspiration field, conservative do not want to take a step until the two years before Toyota, Honda launched its own 1.5T and 2.0T engine?
Do not forget, as early as 2011 Dongfeng Nissan Turbo Charger launched TIIDA GTS, equipped with a 1.6T turbocharged MR16DDT engine, which is the Japanese depot in China's first turbocharged models. If you are a senior fan, to understand Nissan turbo history, know that Nissan has produced GTR R32, R33, R34 equipped with RB26DETT turbo engine, you will be completely reassuring Nissan.
But a pair of looks good engine, wrong on a TIIDA body, the final outcome is to stop production.
TIIDA GTS This pair of MR16DDT, is the first deputy of the Department of turbocharged machine, only in foreign equipment Juke small SUV, has been well received. Like VQ, the MR series engine is the dominant driver of Nissan and Renault small cars with 1.6L, 1.8L and 2.0L of gasoline engine displacement. MR16DDT and ordinary TIIDA MR16DE Turbo for sale that there is a big difference, the displacement is also a small difference, not natural suction version of the plug-in turbine so simple. MR16DDT is more in the larger displacement of the MR18DE based on the narrowing of the development of the cylinder (bore 79.7mm), all of the two strokes are 81.1mm, are all aluminum alloy structure, and thicker cylinder can guarantee pressurization The durability of the machine.
MR16DTT has a large number of new technologies, design ideas are different from the European car, Nissan more emphasis on the reliability and economy of the machine. Nissan called DIG-T (Direct Injection Gasoline Turbo-charged) turbocharged direct injection technology, fuel injection into the cylinder twice, although only low temperature start with stratified combustion function (this effect mainly to reduce emissions), and General SIDI the same role, but also can play a role in improving fuel economy.
Although there is no variable lift technology, but MR16DDT has both intake and exhaust side of the "double variable valve timing" technology, this point even the GTR VR38DETT are not. But the same, MR16DDT uses the same engine technology as Nissan GTR, such as sodium-cooled exhaust valves, lightweight and low-friction internal design, nano-precision machining of the camshaft, honeycomb valve spring, etc., which reduce the engine interior Sports resistance play a key role, usually we said Nissan engine particularly "smooth" also derived from this.
Even we have been worried about the issue of burning oil, Nissan has also been taken into account, through the piston to increase the special oil tank, the excess oil recovery, to avoid the oil into the cylinder burning out.
Now TIIDA GTS has been discontinued, but then I have tried to drive TIIDA GTS, what kind of experience will be?
If you are accustomed to TIIDA has always Electric Turbo been very quiet car environment, then the GTS will give you a different feeling, start the engine after the car will always be accompanied by "rumbling" low noise. 190 horsepower and 24.5kgm torque is not really covered, the speed of a pointer on the pull you crazy forward, then the same size of the domestic car, and only 6 generations of golf GTI to get it. In the past, the natural suction version of TIIDA torque concentrated in the low-emission release, the speed after 3000rpm after the noise will increase, but the acceleration began to weaken, but TIIDA GTS is completely different, and other indicators after passing 4000rpm, power Still continue to come, it is easy to speed up to 180km / h.
MR16DDT does have the tendency to adjust the movement, after the speed of 4000rpm, the pointer instantly climbed to the red line, if you use the 6MT manual block, shift slower will be busy. MR16DDT design ideas and the European depot is different, the Japanese relatively pure pursuit of the performance, the use of large turbines squeeze more powerful power, but it also led to the maximum torque of 24.5kgm postponed to 2400rpm release, how many will Low torsion is somewhat inadequate. But very pleased, normal driving when you are not easy to aware of this, the turbine involved in the work fairly smooth, hysteresis is there, but not obvious.
By the way, there is no Infiniti ESQ this model, it is Nissan Juke for a vest, Infiniti specially prepared for the Chinese market models. So all of its performance, including NVH performance or Nissan level, of course, ESQ sales is bleak.
Infiniti ESQ, it should be said that Nissan Juke also use this pair of MR16DTT 1.6L turbocharged, in the ESQ above the MR16DTT also deliberately increased power, output up to 147kW / 6000rpm and 250Nm / 2400-4800rpm, the data with a pair Excellent 2.0T engine is almost the same.
