Recently, all major mobile apps have provided users with 20 19 evaluation. Did you bring your thoughts back to the beginning of the year? As a "trendsetter" in the era of big data, with the continuous progress of high-tech technology, it has changed people's lifestyles too much.
Among them, with the progress of science and technology, automotive technology has been continuously improved in the automotive field, and many black technologies have been added to the automotive field, which has brought different car experience to consumers. Which engine black technologies will be popularized in China automobile market in 2020? Do you have any expectations for these?
Golf 8? MHEV
As Volkswagen's most famous car in China, every generation of its model changes affects the hearts of Volkswagen fans. On June 24th this year, 10, the official map of the Eighth Generation Golf was officially unveiled, which means that the Eighth Generation Golf will meet the fans soon.
According to the current information, Golf 8 is expected to be officially listed in 2020, but in terms of power system, Golf 8 will introduce MHEV light mixing system, which is not available in previous golf models.
It is reported that Golf 8? The MHEV model will be equipped with 1.5T engine. In order to further reduce fuel consumption, at the same time, it is equipped with an 8kW starter motor to work at the same time. In addition, Volkswagen Group has also developed a set of MHEV? The power system is added, and the motor can be placed on the rear axle of the new car to realize the four-wheel drive mode. The maximum horsepower of the motor can reach 35PS, and the maximum horsepower of the whole power system can reach 183PS, which is also expected to appear on Golf 8.
SKYACTIV-X？ engine
With the next generation Mazda 3? Axela officially went on the market, and still used the upgraded 1.5L and 2.0L engines of SKYACTIV-G series, which made many "horse powder" disappointed, but the previously announced SKYACTIV-X engine still could not be adopted.
The biggest difference between SKYACTIV-X engine and traditional gasoline engine is that it has Mazda's original "SPCCI(Spark? Controlled? Compression? Ignition) spark control compression ignition technology, its concept is to mix diesel combustion technology with gasoline for ultra-lean combustion. In fact, it is necessary to overcome many difficulties to realize compression ignition of gasoline engines. First of all, the compression ratio of gasoline engine is small. If the compression ratio of diesel engine is high, there will be knocking inside the engine, which is very harmful to the engine.
On the other hand, the fuel consumption of models equipped with SKYACTIV-X engine is two to three times lighter than that of traditional gasoline engines, allowing switching between spark ignition and compression ignition. Mazda claims that its fuel economy has improved by 20% and its carbon dioxide emissions have also decreased.
Honda plug-in hybrid technology
Honda, which has always been "buying an engine to send a car", has a persistent heart for the research and development of internal combustion engines. However, with the stricter emission regulations, the science student, the automobile manufacturer, has also begun to get an electric shock. At present, in addition to matching HEV hybrid systems for its Accord, Odyssey and other models, Honda will also launch PHEV plug-in hybrid vehicles in 2020.
This PHEV system is improved on the basis of Honda i-MMD hybrid system, so before introducing this PHEV system, let's briefly review Honda i-MMD hybrid system. Relatively speaking, the main structure of Honda i-MMD hybrid system is relatively simple, consisting of an engine, an E-CVT and two motors. Theoretically, the mechanical energy generated by engine operation can be directly transmitted to the drive axle through the E-CVT gearbox, or it can drive the 1 motor to generate electricity, and drive the No.2 motor to be converted into mechanical energy and transmitted to the drive axle. ?
In the case of low speed and rapid acceleration, the connection between the engine and the drive axle is completely disconnected, and the mechanical energy of the engine is completely converted into electrical energy for the vehicle to run; When cruising at high speed, the engine will be directly connected to the drive axle to drive the car, while the 1 motor and the No.2 motor will stop working completely. This system is a hybrid system mainly driven by pure electric drive, or more like an extended-range electric drive system, which has the function of direct engine drive.
Mercedes-Benz brand-new engine -M254
Recently, Mara Auto Market learned from Beijing Benz that Mercedes-Benz will be equipped with brand-new M254 series 1.5T and 2.0T engines, which will cover three models of Beijing Benz, namely GLC, C-class and E-class. It is reported that the new engine will be released in 2020 and is expected to be put into production on 202 1.
Technically, the new M254 engine should not only meet the power of Mercedes-Benz models, but also further improve efficiency and reduce fuel consumption and emissions. The new engine technologies include ISG motor (starting and stopping), electromagnetic injection technology, LSD cylinder liner spraying technology, adjustable oil pump technology, and special balancing shaft, hollow valve, electronic water pump, timing system back position and other devices to improve engine efficiency.
In terms of power, the official M254 series includes 1.5T and 2.0T engines, and the engine power is 77.8- 1 15kW/L, which means that the maximum power of the 2.0T engine reaches 230kW, which is obviously improved compared with the current 2.0T engine.
Ma Yue:
As the core component of automobile, engine technology has risen to a new height with the continuous breakthrough of science and technology. When getting off the bus, many companies are trying to improve the technology of the traditional fuel engine, and the hybrid system can really guarantee the car experience after adding the motor, even better than the traditional fuel engine, but the higher price has become a threshold. In 2020, the above four black technologies about electricity will be popularized in China market. Which technology do you prefer?
