Hideo, Ke Luze, the more helter-skelter, Ling faction and other models, it can be said that the current market’s best-selling three-cylinder car. Despite good sales, but in public, they are often not recognized by the majority of consumers. Perhaps manufacturers began to realize that some people’s idea is difficult to reverse, its hard bar is better heed public opinion, so that several hot-selling three-cylinder cars in the near future to declare a four-cylinder version.
Hideo, Ke Luze go back to the 1.5L four-cylinder engine, the more helter-skelter to spend a 1.4T four-cylinder engine, but with Ling faction + 1,5L on four-cylinder engine hybrid system combination.
Since then the tortuous route triplex, Is there no way of energy saving yet? In fact, the market has a popular new “operation”, that is change-cylinder technology that allows four-cylinder engine into a “two-cylinder” engine in certain conditions, so as to achieve the purpose of fuel. What are brands with? Today, Jiang brother come to you take inventory. .
1 General 2.0T engine
Maximum power: 241 hp, peak torque: 350Nm
Representative models: Cadillac CT5 / XT4 / XT6
In among the many car prices, regarded as the Cadillac is the first application of variable cylinder technology research and development, as early as 1981, when it has already become a 6 L62 V8-6-4 engine 4 to the production out.
The current, four-cylinder common title is made into a two-cylinder turbocharged engine 2.0T.
The engine cylinder achieve a variable, mainly rely on three-sliding cam. The three-stage slide camshaft in operation, allowing the valve respectively in a large number of long-term intake, and no small amount of air intake three states. Where no long-term intake state, on behalf of the cylinders 2 and 3 is closed, does not work.
It is worth mentioning that this engine Cadillac fuel into this mode, the car does not need a power transferred to a specific mode, the system determines whether the engine requires only minimal torque to maintain the balance, the system will automatically shut down two cylinder, very intelligent.
In fact, through the promotion of technology and triplex closed cylinder technology, currently GM’s models, fuel consumption has been significantly improved. Like this variable 2.0T engine cylinder, fuel efficiency can reach 15 percentage. So the next time the US Department says a high displacement, high fuel consumption, can first see it with what a job engine.
Ford 1.5T engine 2
Maximum power: 174 hp, peak torque: 243nm
Representative model: Fox
had a three-cylinder engine has a cylinder less is innate, while Ford was also to make it a little longer, Ford fuel economy can be described as painstaking in order by closing cylinder technology.
in front and three-Cadillac use different cam slide, a three-cylinder Ford becomes 1.5T achieve this two-cylinder, mainly closed by variable cylinder control valve and the rocker arm to achieve.
the system detects a vehicle load when the load is low, it will let the control valve closing cylinder inside a cylindrical ejection control, and then the card that live variable rocker arm, thus achieving closing cylinder. Iron posts to extend into the closing cylinder, this engine will not react Pianman it? In actual fact, according to the official Ford introduced, it’s this close cylinder switch just 14 milliseconds to complete.
Although there are many Ford’s three-cylinder models, but Ford’s, in fact, only Fox and Fox Active Both vehicles are equipped with this 1.5 T variable three-cylinder engine cylinder.
It is worthMentioning that Fox above paragraph to the outbreak of the 1.0T 125 horsepower three-cylinder engine, also have close cylinder equipped with this technology. .
3-Benz engine 1.3T
Maximum power: 163 hp, peak torque: 250Nm
Representative models: GLB
Mercedes GLB car can be regarded as the most self-confident 19-year price of a car, engine displacement of only 1.3, the price is dare to 314,800 from the point, for this fan confident, Xinjiang brother also some admiration. But then again, Mercedes-Benz, this 1.3T engine displacement, although small, but there is some material, but he is a lot.
In addition to the industry that rare triangular design than the cylinder head ( convenient placement of parts, to improve the center of gravity), in place of the liner to cancel it, machined with mirror-finish honing process of spraying the film, further enhancing weight reduction.
Of course, it is necessary to spend a closing cylinder technology, this 1.3T closing cylinder engine, primarily by controlling valve lift, in cruise mode or smaller power demand time shut off the cylinder 2 and 3. At the same time, it also increases the load cylinder still working to reduce pumping losses by increasing the throttle opening, so as to achieve the objective of saving. But afford a Mercedes who will care about the fuel consumption it?
It is worth mentioning that Leinuokelei Bean also said that the use of this engine, but because it is not equipped with an engine that money can variable valve lift technology, so it does not have the closing cylinder capacity. Therefore, only its 1.3T Benz engine with variable cylinder capacity closing cylinder two cylinders.
In addition to the foregoing has several domestic production of a multi-cylinder engine can be done outside the cylinder becomes two, the mass thatThe amount of money abroad have produced 1.5T 4-cylinder engine provided with the same closing cylinder capacity. It is said that this engine will be introduced this year as golf 8 in the country, but close cylinder technology will not be castrated after the introduction, is not yet known.
Jiang Columbia, roughly Compared to reduce the number of cylinders, the above-described technique closing cylinder is undoubtedly more acceptable to people, more representative future technology engines. In Xinjiang brother seems, as more stringent emission regulations, the traditional internal combustion engines, both horses run fast, but also eat it too, perhaps to reduce emissions by closing cylinders, ultimately saving and environmental protection both the general trend, but also the desire of the people. So for these “two-cylinder” engine, do you recognize it?
