At the 2020 Beijing International Auto Show, major car companies competed on the same stage, becoming an excellent place to show their product upgrades and brand upgrades. In the recent hot medium and large SUV market, there are more and more Chinese brand layout models, such as the new generation of Jietu X90, Geely Haoyue also showed a heroic posture at this auto show.
For the medium and large SUV market of Chinese brands, what are consumers most concerned about? In addition to the experience of spatial comfort, motivation may be the primary decision factor for consumers. The "2019 China Automobile Consumption Trend Report" also shows that in the process of consumer car purchase decision-making, the decision-making path is disorderly, and the brand is becoming more and more borderless, that is to say, users pay more attention to the product itself and care more about the experience, especially for medium and large SUVs, the power experience is particularly so.
The basic parameters can also see a lot of doorways
The advantages and disadvantages of the power engine is the core element, first of all, we need to understand the technological advancement of the engine, to the new generation of Jietu X90, Geely Haoyue as an example, respectively, equipped with 1.6T and 1.8T engines, the two engines have won the "China Heart Top Ten Engines", both use the cylinder direct injection of fuel supply mode, this way oil and gas mixture atomization, combustion is more sufficient, fuel has better economic performance, while improving the power and compression ratio, Power and torque can theoretically be increased by 10% compared to engines of the same displacement.
From the material point of view, the former 1.6T engine uses a more wear-resistant, better heat dissipation, lighter weight aluminum alloy material, the engine performance has a great gain, the latter is a conventional cast iron material. On the book data, it is often seen that the maximum power and maximum torque are two sets of parameters, and the two have wins and losses for each other, basically at the same level. These two parameters are popularly speaking, the maximum power represents the maximum speed that the vehicle can achieve, and the maximum torque represents the starting acceleration performance of the vehicle. It is worth mentioning that the rear multi-link suspension of the new generation of Jietu X90 is equipped with structural advantages that make it better for the filtering and comfort of bumpy roads.
The power and torque of the liter can best reflect the advantages and disadvantages
Friends who have a certain understanding of the engine must know that the rising power and rising torque is the core indicator that reflects the advantages and disadvantages of an engine, and the larger the value, the higher the engine strengthening, the more advanced the technical level, and the greater the power and torque, the better the engine.
Liter power is the maximum power emitted by the working volume of each liter of cylinder, reflecting the quality of the engine is mainly to see the power and economy, the liter of power is to reflect the engine to power and fuel consumption relationship index; liter torque is the maximum effective torque that can be emitted per liter of engine displacement, it is a reflection of the technical level of the engine, the greater the liter torque, the better the engine performance.
From the comparison chart, it can be seen at a glance that the 1.6T engine liter power and liter torque parameters of the new generation Jietu X90 are significantly ahead of the Haoyue's 1.8T engine. Mainly due to the fact that this engine adopts the domestic top iHEC (intelligent effect) combustion system and engine thermal management technology, as well as the technical optimization of friction, lightweight and NVH, with the advantages of large torque, low fuel consumption, low emissions, low noise, etc.; the use of a faster response to the small inertia turbine, low speed that releases the maximum torque, the middle and rear section of the speed range will not appear torque attenuation; the cumulative 15,000 hours of bench verification and the cumulative vehicle verification of more than 2 million kilometers, the reliability is also guaranteed. And Chery Jetway also provides lifelong engine warranty services at this stage, and there is basically no worries about using the car.
Therefore, if there are certain requirements for power when choosing a car, we must carefully study the various parameters of the engine and put the alternative models together for horizontal comparison, so that we can buy a good car that is satisfactory, of course, combined with the actual test driving experience.
