Don't just stare at the Japanese series, 4 high-thermal efficiency domestic engines inventory, the last one has a thermal efficiency of 40%

1, the 4B20J1 0T engine carried by Trumpchi GS8 is the third-generation turbocharged direct injection engine under the GAC G platform, which The thermal efficiency of this model has reached 38%. The maximum power of this engine is 185kW, and the peak torque reaches 390N·m, which is 37kW and 70N·m higher than the second-generation engine respectively.

2. Nissan's KR20DDT engine ranks fourth. This engine is mainly installed in the Japanese brand's own high-end car series - Infiniti QX50. At present, the engine thermal efficiency of KR20DDT is 39%.

3. The Blue Whale engine has more than 100 patented technologies, and has won the title of China's top ten engines for three consecutive years. The highest thermal efficiency of this engine can reach 40%, and the Blue Whale 4T high-pressure direct injection technology can output a peak of 260 Nm, and the peak output of Volkswagen EA 211 is only 250 Nm.

4. It is worth mentioning that before the mass production of Mazda SKYACTIV-X, Toyota's hybrid system was the most thermally efficient mass-produced engine.

5, Chang'an 4T Blue Whale Chang'an Automobile's 4T "Blue Whale" engine adopts high-pressure direct injection technology, with a maximum power of up to 116Kw (158Ps) and a thermal efficiency of up to 40%. At present, it has been installed in Chang'an CS35Plus, Chang'an Xinyidong and other models.

Take stock of the top ten models with engine thermal efficiency, Mazda is the first!

"Technology House" Mazda has been at the forefront in this area. The thermal efficiency of the SKYACTIV-X 0L engine it has developed is as high as 43%, and it is installed on the overseas version of Mazda 3 Enclavera.

CA4GC 0T is mounted on the Red Flag HS5 model, and the engine thermal efficiency is as high as 39%.This engine has a power of 185 kilowatts and a torque of 380 Nm. This engine should be the most thermally efficient independent brand engine that has been mass-produced and listed so far.

Mazda 3 Enclave officially launched the compressed combustion version equipped with the SKYACTIV-X 0L engine on September 16, 2020, with a thermal efficiency of up to an amazing 43%, which is obviously the 5L hybrid with a thermal efficiency of 41% on the Toyota Camry twin-engine version. The motivation is even higher.

First place: Mazda 0 compressed combustion engine, with a thermal efficiency of up to 43%. When it comes to Mazda, everyone is very familiar with it. As a car company obsessed with technology, Mazda's SkyActiv-X compressed combustion engine can have a theoretical thermal efficiency of up to 43%.

MaZda SkyAction X Engine Thermal Efficiency: 48 Model: Mazda Mazda 6 Mazda's engine adopts Atkinson cycle to improve thermal efficiency by changing the compression ratio and ignition method. Its core is &ldquoSPCCI&rdquo technology, that is, compressed combustion technology controlled by spark plugs.

First place: Mazda's skyactiv-x 0L ranked first is Mazda's skyactiv-x 0L engine, not Honda, which has been talking about the engine, which makes the author somewhat surprised. The skyactiv-x 0L engine The thermal efficiency has reached 43%.

Mazda has strong power and low fuel consumption. What is the magic of its compressed combustion engine?

1. Learned a Mazda 3 specification sheet from Slovakia, which shows the power and torque data of the SkyActiv-X engine; it can be seen that the Skyactive-X engine can produce 180 horsepower and 222 Nm of torque.

2. But you can acceptIt is certain that in the future, these two domestic Mazda models with compression power will bring a large number of true fans to Mazda and become the focus of the industry's attention. Because Mazda's SkyActiv-X compressed combustion engine is indeed technologically advanced.

3. The engine is also equipped with 24 v light hybrid systems, which can improve the power of the engine and reduce the fuel consumption of the engine. 48 adopts different systems from mainstream manufacturers, and Mazda chooses a hybrid power system with lower voltage. The engine is matched with a 6at gearbox.

4. Through compression combustion technology, Mazda can make the 0L engine produce a maximum power of 180 horsepower. Mazda has made a lot of efforts to mass-put compression technology.

What is the thermal efficiency of Mazda's latest Chuangchi Blue Sky

1. The current Chuangchi Blue Sky is 38%, and the second generation is more than 50%. In addition, after cooperating with Mazda, Toyota used Chuangchi Blue Sky technology and its own hybrid technology to make a hybrid engine with the highest thermal efficiency of 41%.

2. Recently, Honda announced that the thermal efficiency of the engine prototype has reached 42%, while Mazda's second-generation Chuangchi Blue Sky technology is said to have a thermal efficiency of 50%.

3. However, it is not the purpose of letting gasoline compress. The core value of SPCCI is to use such a complex ignition method to stably release the mixed gas with an air-fuel ratio of up to 38:1.Energy, so as to achieve the ultimate goal of improving efficiency - the thermal efficiency of the e-Chuangchi Blue Sky X engine is said to reach 43%, exceeding the previous highest record of 41%.

4. First place Mazda Chuangchi Blue Sky SKYACTIV-X Engine 43 Mazda is a "technology house" in the automotive industry, stubborn and persistent in the research and development of engine technology. In 2019, the Mazda 3 Enclave equipped with the SKYACTIV-X 0L engine was launched. This engine uses the second-generation Chuangchi Blue Sky technology, with a thermal efficiency of up to 43%.

5. Through Mazda's original spark plug ignition control compression ignition (SPCCI) technology, more ideal efficient combustion is achieved. The advantage of SKYACTIV-X is the value it brings: that is, the fuel economy is greatly improved.

The three engines with the highest thermal efficiency are recognized, Toyota and Honda are both on the list. If you want to save fuel, please take a look_Baidu...

First place: Mazda 0 compressed combustion engine, with a thermal efficiency of up to 43%. When it comes to Mazda, everyone is very familiar with it. As a car company obsessed with technology, Mazda's SkyActiv-X compressed combustion engine can have a theoretical thermal efficiency of up to 43%.

Toyota's engine technology is very advanced, such as its intelligent variable valve timing system (VVT-i), with 41% ultra-high thermal efficiency, and Toyota has won more than a dozen awards since the establishment of the Ward Agency. Honda cars.

It is also mentioned above that the thermal efficiency of the Toyota Camry twin-engine 5L hybrid engine reached 41%, and long before the mass production of Mazda SKYACTIV-X 0L compressed combustion engine, Toyota's 5L hybrid engine was recognized as the most thermally efficient model in the world, and at present It can only rank second after Mazda.

So Honda's L15B engine is "the most fuel-efficient" and reliable in 5T class. The third model is Nissan's 6L naturally aspirated engine code-named HR16.

cx4 thermal efficiency

The thermal efficiency is very high. Looking at the gearbox, it still adheres to the most reliable traditional automatic transmission. Overall, CX4 is a very unique, at least a little bit of Mazda's spirit and concept. Personally, I like this car very much, otherwise I wouldn't recommend so many cars to my friends around me.

Secondly, 0 and 5L engines are all naturally aspirated machines! Coupled with the control system of the intake valve delayed shutdown, the machine can enter some Atkinson cycle mode. The thermal efficiency is very high.

The Mazda CX-4 Blue Sky Sport Edition is equipped with a 5L Chuangchi Blue Sky engine. High thermal efficiency makes CX-4 have good fuel economy. With the logic intelligent gearbox (imported), the power is smooth and the gear shifting is very flexible.

The quality of Mazda cx4 is very average and the failure rate is not too high. However, although there are no major problems, there are still many defects, which also leads to the reputation of Mazda cx4, and the sales volume is even more sluggish.

Mazda CX-4: equipped with 0L, 5L engine, power performance. First of all, after the change of MAZDA CX-4, there are 0L and 5L engines, a total of 8 models, and the price is also 10,000 to 20,000 yuan. The new Mazda CX-4 is not brand new, it is just a safety upgrade and technology. The original basis of the art configuration.
