engine is one of the core parts of the car, is the power source of the car. How the performance of an engine, has a direct impact on the owner of the car experience. In recent years a lot of car prices in the introduction of the new car’s engine, will be referred to the thermal efficiency of the word. Toyota previously mentioned when publishing TNGA architecture, fuel version of the model in the framework of up to 40 percentage engine, engine thermal efficiency dual-engine version of the model is to reach 41 percentage, this ultra-high thermal efficiency at the time was caused extensive heat conferences attention. However, the thermal efficiency of the engine in the end what is?
is well known, the engine is generating a high temperature and pressure through a combustion chamber of the fuel combustion to promote movement of the piston so as to drive work generated power crankshaft rotation. However, the heat generated during the combustion of fuel into mechanical energy in fact, most of the heat will be lost in various forms, so the real energy into mechanical energy will percentage between 30 and 40 percentage. Here is a simple example, 10 people together to do one thing, but the real work is only contribute 3 to 4 people, so it’s “thermal efficiency” is 30 percentage to 40 percentage. So what are the benefits of high thermal efficiency? Not only the higher thermal efficiency of the engine is more fresh, but also more fuel-efficient.
Further, the heat efficiency is very difficult to enhance a desired percentage, to access the inside of each engine kinds of complex and sophisticated design and renovation. Currently the engine thermal efficiency of the market most of the models equipped with between 36 to 38 percentage percentage, so this is why when the ultra-high thermal efficiency of Toyota’s Dynamic force range of the engine can cause widespread concern. However, independent car prices in the domestic auto market during the golden period of ten years, their core technology has also made great progress, and now a number of independent thermal efficiency and performance of the engine car prices is not lost engine joint venture enterprises. Such as engine, the thermal efficiency of these three companies will be able to shoulder the independent car than the Toyota.
The 1.5T engine, code-named C15TDR belong to Dongfeng Fengshen latest power system, after BARI Huacheng certification, the thermal efficiency of this engine has reached 41.07 percentage, the maximum output power 150kW (204Ps), maximum horsepower 320Nmiddot; m, b satisfies six States emission standards. This engine thermal efficiency can reach this level, but also the highest thermal efficiency of more than 41 percent of Toyota Dynamic force series engine in the industry leading level.
Aeolus C15TDR 1.5T wind has been able to achieve such a high engine thermal efficiency and robust performance, because of the introduction of highly active anti-knock rapid combustion system, the depth of the friction reducing technology and intelligent and efficient thermal management. Wherein the combustion system integration integrated Atkinson cycle, high tumble ratio and a high compression ratio of the combustion chamber inlet, 350bar high-pressure injection systems, electronically controlled low inertia supercharging system efficiency, high-pressure cooling EGR technology. E.g. 350bar high-pressure injection system, the fuel can be better atomized, and thus better mixing of air, combustion will more fully. Efficient and low inertia supercharging electronic control system may rapidly increase the intake air amount of the engine, an engine low torque so that a more adequate, while significantly reducing turbo lag. In addition, the Dongfeng Fengshen C15TDR 1.5T engine, this ultra-high thermal efficiency of birth, car prices also means that the independent research and development level of a new breakthrough. It will apply to the future which models of Dongfeng Fengshen? We’ll see.
As the head of its own brand one car prices, Changan automobile in recent years can be said to bring us a lot of surprises, the blue whale NE power platform is one of them. Blue Whale NE is a synchronous dynamic platform developed by Chongqing Changan Automobile headquarters and the center of the United Kingdom and the experimental results, according to official reports, the blue whale NE power platform is compatible with 1.0L-1.8L displacement, another blue whale NE dynamic platform preset Europe 7 upgrade path, with 3.0Nm / kg of weight specifications, compatible with the entire system light mixed 48V, the HEV hybrid, plug the PHEV hybrid, hybrid REEV extended-like design.
Blue Whale NE 1.5T engine that everyone is familiar, the UNI-T and Chang’an CS55 PLUS and so the models are equipped, the maximum output power of 132kW (180Ps), maximum torque of 300 Nm, the thermal efficiency of up to 40 percentage, can be described as shoulder than the Toyota. In this engine, the first application of automotive Changan twin-scroll turbochargers electronic exhaust valve, the intake air not only reduce interference, but also to reduce turbo lag. Therefore, blue whale NE 1.5T at 1250rpm can burst 300Nmiddot; m of the maximum torque. Moreover, this engine also uses Changan Automobile original AGILE combustion system, can further control exhaust emissions, to meet the national emission standards for six b. Further, high-pressure injection system as 350bar, Schaeffler latest dual VVT actuators are used in this engine. From the point and perspective, Changan Automobile R & D capabilities in a public autonomous car prices, is indeed very prominent.
In March this year, FAW when listing Pentium T77 PRO, which is mounted on the engine also caused 1.5T hot. Because the thermal efficiency of the 1.5T engine, code-named 4GB15TD can be reached 39.6 percentage higher than the current average level of the market most of the thermal efficiency of the engine, and has been third-party authority BARI thermal efficiency 001 certification. In addition, the FAW Pentium 1.5T this engine can output maximum power 124kW (169Ps), maximum torque 258Nmiddot; m, b satisfies six States emission standards.
on the 1.5T engine, code-named 4GB15TD, FAW Pentium application of wisdomThermal energy management module technology, intelligent electronic control piston cooling nozzle technology, two-step variable flow oil pump and center VVT ventilation technology and other advanced technology, allow the engine to be more reliable and fuel-efficient. In order to achieve the thermal efficiency of 39.06 percent, this engine also uses a Miller cycle efficient techniques, 350bar high-pressure injection system, so that more complete combustion of fuel, stronger explosive force. After improving Power, FAW Pentium sales this year climbed again, showing the importance of a good engine.
