Imported brand new engine
● Fiat MultiAir engine 2.4 liters
The first time I saw this engine is Fiat's auto show in 2013, but the surprise is that this engine is actually put on the Jeep booth, engine nameplate bearing the words below come from this 2.4-liter engine equipped with Fiat Jeep liberty in light models.
Before we make an article named breathing tract article,clio turbo which describes the technology developed by various manufacturers in the gas distribution system, part of the engine is used, which take advantage of the technology-led electro-hydraulic variable phase timing technology is great most people know, however, there are also individual manufacturers to use their own ways to achieve functional variable timing, and Fiat has launched a variable timing technology is that more special.
From the surface structure, which is an engine SOHC (single overhead camshaft) structure, according to conventional thinking judgment, each cylinder of this engine should be only two valve (are responsible for the intake and exhaust), but this is actually a four-valve engine has, chain driven by the exhaust-side camshaft drives the valve, in theory, can be achieved if the assembly of its phase adjuster conventional exhaust-side variable-timing function, However, this engine is not equipped with the technology.
Also located on the intake side 2 of the valve is controlled by an electromagnetic hydraulic valve, by adjusting the hydraulic system can achieve not only to adjust the timing of valve opening, but also to achieve stepless adjustment of the valve lift,megane turbo and thereby controlling the intake air cylinder gas, in other words, MultiAir technology can replace the traditional throttle device.
Mounted on a Jeep liberty light 2.4 liters MultiAir engine, maximum power of 184 hp / 6250rpm, maximum torque of 232 N • m / 4800rpm, combined with 9AT gearbox use, Jeep liberty light MIIT measured combined consumption of 8.8 liters / one hundred kilometers, one hundred kilometers of high-speed road fuel consumption of 7.6 liters under, for a mid-sized SUV models, such as fuel consumption and performance can be acceptable.
MultiAir technology is when technology is an alternative,megane dci turbo breaking the traditional gas distribution system structure, relying on hydraulic drive opens the valve to achieve stepless adjustment of the valve timing and lift of the many variable. We can say that the 2.4L MultiAir engine and gearbox with transverse 9AT be regarded as a golden combination.
Volkswagen new EA888 engine
In the second half of 2013 for the production of the new EA888 engine Volkswagen factory located in Changchun, which means that the future of domestic Volkswagen and Audi models are relevant will dress up this new engine. Although some of the cylinder parameters of view, both old and new EA888 engine did not differ significantly, but technically, the two are quite different.
