Nissan X-Trail turbo diesel

It was blessed with the opportunity of the Nissan X-Trail turbo diesel to participate in a test-ride event specially. Although this car is already put on the market in Europe, it is introduced into Japan as a clean diesel car of the domestic maker first person to arrive this autumn.
Fuel is made to inject in the place which compressed air within the cylinder and became high-pressure high temperature, and diesel engines are natural ignition and a system which carries out explosive combustion. The gasoline engine which makes it mix with gasoline beforehand and takes the combustion system by plug ignition differs in character naturally.
Are easy to generate PM (particulate matter) and NOX (nitrogen oxide), and a demerit is easy to produce noise and vibration.
A merit is excellent in fuel consumption and is that the amount of emergence of CO2 is environment-friendly few. And the technology which harnesses the merit more has been developed in recent years.
Common-rail type injection of fuel is right. It is a thing of a combustion control system which maintains fuel at high pressure (1800bar), and gives several times of injections of fuel to one combustion by in ジェクター of a ソレノイド type or a ピエゾ type.
ピエゾ type in ジェクター said for the X-Trail turbo diesel which test-rode this time to have the at present highest performance although it is a quite special talk is used.
I will actually go into the impression of a X-Trail turbo diesel.
The feature of the exterior of the Europe specification is a front face. Volume was attached to the front bumper and the slit of the transverse direction is contained in the center. Since インタークーラー is stored here, it serves also as the purpose of the cooling.
It will begin to run instantly. First, engine starting. The sound of an idling is the sound of a diesel clearly. Since it is SUV, it may be allowed and SUV-likeness of X-Trail may be impressed on the contrary more strongly, but probably, the vibration which gets across to a handle needs to take the mount method etc. into consideration to adopt it as models other than SUV.
However, the people from Europe do not say such trifles this and that. Actually, the sales number of Europe is good. Surely must be some reasons there. What on earth is the charm of the X-Trail diesel which diesel power Europe accepts?
The reason of the Europe good condition and its answer were beginning to run, and were understood immediately. sound -- a diesel -- if it begins to run but, it is quiet just like a gasoline engine, and smooth. Although gasoline specification was also test-ridden simultaneously, if it begins to run, the cabin is quieter than gasoline.
Probably the measures against oscillating noise will be taken more. It seems that moreover, it is carrying out happy [ of the thing with a small mechanical noise ] since the use engine rotation region of a diesel engine is low.
ピエゾ type in ジェクター which has high performance stated as mentioned above is adopted as 2.0l. 4 cylinders of serial common-rail type diesel carried.
The effect of this in ジェクター is high and the response of the engine to accelerator operation is actually felt very good. Usually, although it was a diesel engine which tends to become rotation Feer who considered it as Dara - ン, rotation Feer of X-Trail had a thing near a gasoline engine.
Furthermore, surprisingly this engine turns without stress to 5500rpm in which an engine limiter operates. Although a red zone is from 4500rpm, if not careful, it exceeds simply.
Although the 6 速 MT vehicle and 6 速 automatic-transmission car (after-mentioned) carried out by having considered it as the trial ride vehicle and were prepared, I will report the engine number of rotations in o'clock of 100km/h 6 速 and 5 速 in a 6 速 MT vehicle.
6 速 are set to 1900rpm and 5 速 are set to 2200rpm. passing acceleration at a high speed is natural -- it is more advantageous to use 5 速 -- the maximum torque of MT specification calls it 360Nm at 2000rpm but -- since it is powerful, stress is not felt so much with 6 速. This neighborhood is just going to feel the merit of a diesel engine.
Although matching with a diesel and AT was the place where every maker is suffering troubles, 6 速 AT of X-Trail was finished in what it is smooth and easy to treat.
It is the disposal for uniting this with the durability of transmission, although the engine of 6 速 automatic-transmission car has lowered 40Nm of maximum torques compared with MT. However, since 過給 pressure is the same 1.9bar as MT, it is not a degree which holds dissatisfaction including a feeling of acceleration. If it says by force, is a difference with a 6 速 MT vehicle on the 2000rpm level immediately after start?
The engine was called the M9R type and born by joint development with Renault.
A compression ratio is set to 15.6 [ low for a diesel ] (usually around 17), and mitigation of the burden which weakens explosion torque and starts the inside of an engine is aimed at. Therefore, the weight saving of the rotation portions, such as a crank, is carried out, and the response is good like a gasoline engine.
