withCarsWith the rapid development of the industry, more and more consumers are interested inEnergy saving and environmental protectionThe requirements are also getting higher and higher. And in the fuel vehicle market, smallDisplacementEngineBecause of its advantages of low fuel consumption, high power and low fuel cost, it has become the mainstream choice. And how in smallDisplacementEngineThe integration of cutting-edge technology has become the pursuit of manufacturers. In this article, we'll start with:Volkswagen brand new 15TEVOII engineFor example, its low-carbon and energy-saving technical advantages.
VolkswagenThe Group has always beenTurbocharged engineThe pioneers, the early onesVolkswagen"TSI" seriesEngineWidely known. With the development of the times,VolkswagenA series of different ones were launchedDisplacementof pressurizationEngine, such as 12t、1.4t、1.8t、2.0t and 30t, etc. And in order to conform to the trend of low carbon and energy saving,SAIC VolkswagenBrought a brand new one1.5tevoiiEngine, as **DisplacementEngine, its highlight technology is remarkable.
As a cutting-edge productEngineVolkswagen1.5tevoiiThere have been a number of technical upgrades. One of the most striking is from:PorscheofVariable geometry turbochargerTechnology. One of the major advantages of this technology is that turbo lag is significantly reduced, while the maximum intake pressure is increased by 30%. This means inEngineLow rpm range,1.5tevoiiThe torque is increased, and the power response speed is increased by about 50%. This feature allows the car to accelerate more quickly in the city, and the power can be released directly by pressing the accelerator.
In order to further improve the utilization rate of fuel,Volkswagen1.5tevoiiEngineadoptedVolkswagenThe most advanced direct injection system. The system uses 350 bar high-pressure fuel injection to make the gasoline particles smaller, fully contact with the air, and burn more fully. This technology can be described as the decentralization of high-end technology, withVolkswagenofea888seriesEngineThe same direct injection system is used. In addition,1.5tevoiiEngineThe Miller cycle is also used, which is mainly used to improve fuel economy. By inTurbocharged engineMiller loops,1.5tevoiiFuel consumption dropped by 86%。In the actual road test, it is mounted1.5tevoiiEngineofLavidaThe combined fuel consumption is only 6L 100km, which is already at the same level as some hybrid models in the same class.
ExceptEnergy saving and environmental protectionaspects of the advantage,Volkswagen1.5tevoiiEngineThere is also a significant improvement in power performance. It has a maximum power of 118kw,Maximum torque250 N·m. In order to meet the needs of different usage scenarios,1.5tevoiiEngineTargeted optimizations have also been made. In urban driving, the power output at medium and low throttles is increased by 60 percent, and fuel consumption is reduced by 30 percent. And in high-speed driving and hard acceleration scenarios,1.5tevoiiEngineofMaximum torqueThe speed range has been increased from 1750 3000rpm to 1750 4000rpm, which makes it possible:EngineIt performs better in power ductility. In addition, in terms of sound insulation and vibration,1.5tevoiiEngineAlso adoptedVolkswagenThe family's noise-optimisation technology allows noise, vibration and harshness to be effectively controlled.
In addition to optimization in terms of power and fuel economy,Volkswagen1.5tevoiiEngineI also paid attention to itHeat pipesImprovement of physical efficiency and heat dissipation performance. Adopted intelligenceHeat pipessystematic1.5tevoiiEngineCan be promotedEngine40% of the warm-up time. The system is inEngineIn the warm-up phase, the water flow is turned off to speed up the heating of the coolant, so as to heat up quicklyDuring the shutdown phase, the electronic valve locks the waterway to avoid heat loss and reduces the warm-up time for the next use. In addition,1.5tevoiiEngineIt also adopts APS plasma cylinder coating technology, and the thickness is only 03mm。This coating technology not only lightens upEngineThe weight has also been raisedEngineheat dissipation performance.
In general,Volkswagen1.5tevoiiEngineWith its cutting-edge technology and superior performance, it is in the same classEnginestand out. It'sVariable geometry turbocharger, high-pressure direct injection system, Miller cycle and other technologies make it have the characteristics of high efficiency and low fuel consumption. At the same time,1.5tevoiiEngineThe power and response have also been significantly improved, and a good balance has been achieved in terms of fuel consumption and power performance. Through intelligenceHeat pipesmanagement system and APS and other advanced technologies,1.5tevoiiEngineofHeat pipesThe thermal performance has also been significantly improved. All in all,Volkswagen1.5tevoiiEngineNot only satisfies the consumer's pairEnergy saving and environmental protectiondemand, but also provides excellent power performance and driving experience, becoming smallDisplacementEngineLeaders in .
