In 2022, the domestically listed joint ventures/imported/domestic vehicles are more than heV hybrid or PHEV plug-in hybrids, and it seems that the entire industry is developing in the direction of electrification. But this does not mean that the traditional internal combustion engine field has completely stopped, including the German/Japanese/American system, including the major car companies are still trying to play a new trick in the field of inline four-cylinder and inline six-cylinder internal combustion engines, for example, the following five.
●Volkswagen EA888 2.0TSI evo4
▲ Application models: Audi Q6, Porsche Macan, Golf R
▲ One sentence comment: the magic reform potential is large, I don't care, cast iron cylinder body in the world first!
The Volkswagen Group has not tried electrification in the field of household cars, and has previously launched a three-clutch PHEV plug-in mixing system based on the MQB horizontal platform, and the Passat plug-in mix is still in use today. But it is clear that this system is not a threat at all in the eyes of Toyota THS and Honda i-MMD, and today's Volkswagen has completely focused on the focus of new energy on the pure electric vehicle of the MEB platform, such as the ID series.
SAIC Audi Q6
In the field of fuel vehicles, Volkswagen does not seem to be bothering to make a new plan for the gasoline engine, the fourth-generation EA888 2.0TFSI evo engine that will be equipped on the SAIC Audi Q6 is still a cast iron cylinder block, but in the data, the EA888 imported by this machine is much stronger than the domestic third-generation EA888, and the book data has come to 195kW/400Nm. More importantly, the EA888 was tuned to 235kW/420Nm on the European version of the Golf R, which also gave users who modified the EA888 more confidence.
Volkswagen Golf R
At the technical level, the high-power EA888 evo4 adopts the intake/exhaust double valve lift, which is obviously the treatment that the domestic EA888 evo3 does not have, and designs such as 350Bar direct injection, Miller cycle, and cylinder head integrated exhaust are basic operations. Some people will inevitably say that the cast iron cylinder block is too bulky, but for the public, it can make a cylinder body that meets the high power demand with a lower process cost and a shorter cycle, which is worth the fare. If the cold cast aluminum alloy cylinder block is used like the Mercedes-Benz M139, even if the strength requirements can be met, the excessive production process will not only pull the hind legs of the production capacity, but also the yield rate will be difficult to guarantee, and only Mercedes-AMG is willing to do so.
●Mercedes Benz M139l 2.0T
▲Application model: AMG C 43
▲ One sentence review: small displacement performance monster with electric turbocharger.
As the old saying goes, "Rather 10 horsepower less, less than 1 kilogram", for AMG, which emphasizes extreme performance, the cast iron cylinder block is obviously unacceptable. Whether the tube is the M139 of the horizontal platform or the M139l of the vertical platform, this 2.0T inline four-cylinder engine adopts an all-aluminum cylinder block to achieve the lightweight demand of the whole vehicle. In terms of data, this engine has reached a ceiling-level data of 300kW/500Nm on the AMG C 43, which is close to the 3.0T six-cylinder engine.
AMG A 45 S
How to ensure the strength of such a high-speed engine? The M139 series created by AMG adopts an aluminum alloy cylinder block with reverse layout, the cylinder body itself adopts cold and hard casting process, the crankshaft is forged thermoforming, and the piston is forged aluminum alloy, which can achieve lightweight demand while ensuring strength. In the eyes of peers, perhaps only the price of the Mercedes-AMG series can support such a high-cost process.
AMG C 43
Technically, in addition to the oversized double-scroll exhaust gas turbocharger (roller bearing), the new M139 also incorporates advanced technologies such as cylinder mirror spraying technology, manifold EFI + direct injection in the cylinder, DVVT + DVVL variable valve control and so on. As for the M139l model applied on the longitudinal platform, AMG also tried a motor-driven turbocharger to provide power support through a 48V electrical platform, which has a maximum speed of 175,000 rpm, which can effectively reduce the hysteresis problem of the "big turbine", and with the BSG motor (10kW), it guarantees that the M139l also has excellent power response at low speeds. The data shows that the AMG C 43 using 2.0T+8DCT+4MATIC only takes 4.7s to "break the hundred".
●Toyota D-4ST 2.4T
▲Application model: Lexus NX350
▲ One sentence comment: Toyota THS hybrid to give up "with T"? pattern!
Starting from the TNGA architecture, each new Model launched by Toyota/Lexus basically has a THS hybrid system, but this does not mean that Toyota has completely abandoned the "T" inline four-cylinder engine, for example, the new generation of Lexus NX350 for the Eastern European/Russian market, this car is equipped with a 2.4T L4 engine for the first time, the maximum power is 205kW, the maximum torque is 430Nm, and the displacement advantage makes it more powerful than the 2.0T engine used in most family cars.
From the cylinder block itself, this 2.4T engine uses a 1.14 stroke / bore ratio, which is a typical long stroke design like the A25A engine, plus a high compression ratio of 11:1, water-cooled intercooler, dual VVT-i, variable capacity oil pump, and its fuel economy is not even inferior to the previous generation highlander's 2.0T engine.
Lexus NX350 Fuel Edition
As the latest nose, many new technologies on the Toyota A25A 2.5L self-priming engine have applications in this 2.4T turbocharged engine, such as dual injection technology (manifold EFI + direct injection in the cylinder). At the same time, the engine also redesigned the cylinder head, the straight nozzle was moved to the top of the cylinder for the first time, the four valve angles are also larger than the self-priming series, which is conducive to optimizing the intake roll flow and improving the combustion efficiency, today, this kind of mid-direct injection has become an industry trend, and the way to put the straight nozzle on the side has become less mainstream, especially the double injection engine.
●Mazda e-Skyactiv X 3.0L L6
▲Application model: Mazda CX-60
▲ One sentence comment: SPCCI spark plug control compression technology, only this one has no other branch.
Starting with the CX-60, Mazda began using the front-mounted chassis architecture in a family car for the first time, and on this new platform, the CX-60's three major parts are all renewed, including the new 2.0L PHEV plug-in hybrid, 3.0L E-SKYACTIV X gasoline engine, 3.3L E-SKYACTIV D diesel engine, and the latest longitudinal 8AT transmission, i-Activ four-wheel drive system.
SPCCI's spark plug controlled compression ignition technology
Like the SKYACTIV X 2.0L engine on the Mazda 3, the 3.0L inline six-cylinder engine with the longitudinal layout also uses the brand's newly developed SPCCI spark plug controlled compression technology, which can directly compress the thin oil and gas mixture farther away from the spark plug through the ultra-high compression ratio of 16.3:1 (European version) at low load and high speed cruising, thereby maximizing combustion efficiency and reducing waste.
Mazda CX-60
Of course, there is still a certain difference between the 3.0L compression engine and the 2.0L engine, thanks to the larger displacement, the engine can get enough intake air at low speeds to meet the minimum standards of thin combustion, without the need to add a supercharging module like the 2.0L engine. In addition, including a 3.0L gasoline engine and a 3.3L diesel engine, the CX-60 is equipped with a BGS motor 48V light mixing system as standard.
●Jeep Hurricane 3.0T L6
▲ Application model: Jeep Grand Wagani L
▲ One sentence comment: 172.3Ps/L liters of power, the American "vigorous miracle" represents the case.
The same is the 3.0L displacement of the inline six-cylinder engine, as the representative car company of the American muscle car, Jeep obviously has a completely different understanding of this inline six-cylinder engine. On the new generation of the Big Wagni L, we saw Jeep's newly developed Hurricane 3.0T L6 twin-turbo engine for the first time, which is mainly used to replace the previous 5.7L V8 self-priming engine and 6.4L V8 self-priming engine. Indeed, compared to the previous generation of grand Cherokee, today's 3.0L L6 is indeed a "small displacement".
Wagoneer L ＆ Grand Wagoneer L
You know, the new generation of large Wagni L as a full-size SUV extended version, its length reached 5758mm, wheelbase 3302mm, more than pickup trucks. In order to hold the amazing weight of the car, this 3.0T twin-turbo engine has been adjusted to a maximum power of 516.80 horsepower and a maximum torque of 678 Nm, which is more powerful than BMW's B58, Land Rover's Injeli 3.0 double supercharged, mercedes-Benz M256 engine, which can be called the representative case of American "power out of miracle".
As an iterative engine, Jeep has also worked this new machine head, the cylinder block uses plasma coating injection to reduce piston friction; the injection pressure of the direct injection system also increases the current first-line level of 350Bar, which is conducive to strengthening the gasoline atomization effect; and the two turbochargers use a low inertia design to ensure fast throttle response.
