Pentium T77? PRO is an engine that combines the top technologies of turbocharged engines such as ultra-high compression ratio Miller cycle, 350bar high-pressure fuel injection and high-efficiency supercharger. Among them, the turbocharger adopts single-channel double-inlet volute, high-efficiency compressor technology, low-inertia turbine and other technologies, which makes the maximum torque of the engine reach 258n·m at 1300 rpm, and it can be maintained at 4,350 rpm before it begins to decay, covering the most commonly used in daily driving. Compared with rivals at the same level, BYD Song Pro? The maximum torque of 1.5T engine will only explode at 1600 rpm, but it will decrease at 4000 rpm, and the acceleration performance is far less than that of Pentium T77? Professional.
Specific parameters, Pentium T77? Dear? 1.5T engine maximum power 124kW, maximum torque of 258N·m, transient response speed of low-speed torque increased by about 30%, and it only takes 0.5s from the intervention of supercharger to the realization of maximum torque.
In addition to ensuring strong power output, Pentium T77? The third-generation "intelligent engine" 1.5T engine on PRO is also very fuel-efficient. In order to achieve excellent fuel economy, this engine adopts a number of core technologies, and the thermal efficiency reaches 39.06%. We should know that the thermal efficiency of gasoline engines is generally below 38% at present, and the thermal efficiency performance of the third generation "intelligent engine power" 1.5T can be said to be the best among joint venture and independent brand turbocharged engines.
Generally speaking, there are three basic ways to improve thermal efficiency: increasing the compression ratio of the engine, improving the combustion efficiency, and optimizing the thermal management of exhaust gas and cylinder temperature. The third generation "educated youth power" engine has been upgraded in these three aspects. First of all, its compression ratio has increased to 1 1.5, which is the highest level of domestic 1.5L displacement power. At the same time, thanks to Miller cycle, the expansion ratio is greater than the compression ratio, and more work is done with less force, so that thermal energy is converted into mechanical energy to the maximum extent, and the combustion efficiency of the engine is effectively improved.
At the same time, with 350bar high-pressure direct injection system, atomized fuel is injected into the combustion chamber for three times. Under the action of vortex, tiny oil droplets contact with air to the maximum extent, which makes the mixture burn more fully, thus improving fuel economy. At the same time, the emission is cleaner, and the particulate matter is only110 of the current legal limit, which is extremely friendly to the environment.
Finally, Pentium T77? The intelligent thermal management module technology of PRO engine can dynamically switch intelligently according to different ambient temperatures and engine loads, so that the engine stays at the optimal working temperature for a long time and effectively reduces the fuel consumption of the whole engine.
Thanks to many leading technologies, Pentium T77? With an excellent thermal efficiency of 39.06%, PRO easily obtained the "Energy Efficiency Star" certification No.00 1. Its 1.5T engine has excellent fuel consumption, and the comprehensive fuel consumption of the Ministry of Industry and Information Technology is only 6.8L per 100 kilometers. In order to verify this achievement on the previous Pentium T77? PRO National Fuel Saving Challenge, Pentium T77? PRO has achieved a comprehensive fuel consumption performance of 4.9L/ 100km through actual road test, which shows its fuel saving ability.
For Pentium T77? PRO, a good engine and an excellent gearbox complement each other and form a golden power combination. It can not only affect the fuel consumption of this car, but also determine the ride comfort and ride comfort of this car.
Pentium T77? The gearbox equipped with PRO can be described as the "perfect companion" of the third generation of "intelligent engine power". The 7-speed DCT wet power shift provided by world-class supplier Borgwarner is adopted. This gearbox has the advantages of light weight, high precision, low noise and smooth operation. At the same time, the handling performance is leading, which can provide a smooth driving experience and excellent fuel consumption performance.
"Golden Powertrain" is only the hardware foundation to achieve strong performance and excellent fuel consumption. What kind of car experience this powertrain can really bring is what users are most concerned about. To truly reflect the Pentium T77? PRO's driving experience, we actually went to test drive this car and measured the fuel consumption of this car.
The performance of the 7-speed dual-clutch gearbox is also remarkable, mainly because the ride comfort is very good, and there will be no frustration when you stop and go in the city. At the same time, it responds positively to power output, and is willing to continuously downshift when stepping on the accelerator, and strong power follows.
Summary: Through Pentium T77? After a comprehensive understanding and practical test of PRO powertrain, 1.5T+7DCT? The title of "golden power combination" is well deserved. This power system not only achieves strong power performance, but also has excellent fuel consumption performance. I believe that with such excellent performance, Pentium T77? PRO will be favored and recognized by more and more consumers.
