Unveiled Dongfeng Fengshen Fuel Saving Artifact e-TECO+STT

Recently, the official website of the National Development and Reform Commission officially announced the “Energy Conservation Products Huimin Engineering Energy-saving and Environmentally-Friendly Vehicles (1.6L and Below Passenger Cars) Promotion Catalogue (First Batch)”, including Dongfeng Fengshen including S30, H30, H30CROSS, A60, and A30. All models were selected at the same time to enjoy the most direct 3,000 yuan, showing the strength and responsibility of Dongfeng Fengshen as a central enterprise brand.

It is understood that this batch of energy-saving subsidy threshold has been greatly improved, down to 5.9L. The Dongfeng Fengshen line of products was selected, mainly due to the “e-TECO+STT” gold technology portfolio.

 

e-TECO engine, European standard energy efficient

The e-TECO engine is an energy-efficient engine that has been carefully built by Dongfeng Motor for five years and has completely independent intellectual property rights. The engine adopts the advanced design concept of a well-known European internal combustion engine design company and has the advantages of “three highs and two lows”, namely high power, high fuel economy, high reliability, low noise, and low emissions.

The e-TECO engine finds a perfect balance between power and fuel economy. The engine adopts a number of advanced technologies such as long stroke, variable valve timing VVT technology and offset crankshaft design, which allows the fuel to burn fully, provides more power while providing more fuel economy, plus an all-aluminum cylinder head, The use of cutting-edge lightweight technologies such as thin-walled bodies and compact combustion chambers enables the e-TECO series engines to have both high dynamic performance and high fuel economy. Taking the 1.5-liter engine on the A30 as an example, the maximum power is 89kw, the maximum torque is 150N·m, and the fuel consumption is only 5.9L, which ranks among the top in its class.

In terms of reliability, the e-TECO engine has also been fully protected. The engine is strictly tested in accordance with European standards on the complete machine and its components. After more than 200 test benches and tests carried out for 20,000 hours, at the same time, 800,000 kilometers including “four highs” (high temperature, high The extreme road conditions tests of altitude, cold, high humidity and heat all performed well.

STT Intelligent Fuel Saver 15%, Congestion Road Artifact

The STT smart fuel economy system, which is compatible with the e-TECO engine, is called STOP&START. This is a system that controls the start and stop of the engine.

By embedding a booster starter with an idling start-stop function on the e-TECO engine, the STT smart fuel economy system allows the engine to completely extinguish when the car satisfies the idle stop condition. When the vehicle needs to be restarted, the STT can quickly respond to the driver's start command to quickly start the engine, reduce idle time, and reduce fuel consumption and exhaust emissions. For models equipped with STT technology, Dongfeng Fengshen has adaptive changes to the engine, and frequent starting will not affect the life of the engine.

In simple terms, when the vehicle is in an idle state such as a red light or a traffic jam, the STT can control the engine to temporarily stop running, avoid idling, and stop the operation phase, without affecting the use of equipment such as air conditioners and audio equipment in the vehicle. At the operational level, the driver simply depresses the brake pedal for more than 3 seconds and the engine automatically goes out; when the green light comes on or when the road condition is good, the brake pedal is raised and the engine starts automatically.

Take Dongfeng Fengshen S301.5L Actual Product as an example. Without STT technology, the comprehensive fuel consumption of the Ministry of Industry and Information Technology is 6.2L/100km. The smart drive model equipped with STT technology consumes only 5.9L/100km and the overall fuel consumption. Declined by 5%. The measured data in the urban traffic jam show that the fuel consumption is 8.9L/100km without the STT technology, and the actual fuel consumption is only 7.6L/100km and the fuel consumption is reduced by 15% with the STT technology. Calculated on the basis of 20,000 kilometers a year, the use of this technology can save the owner nearly 2,000 yuan per year in fuel costs.

As a model of the current “micro-blend” technology, STT not only takes the lead in hardware, but also develops and uses advanced, safety and comfort-prioritized control strategies to actively monitor the start-stop environment at the same time without changing the driving experience. By using the car habits, they can save up to 15% of fuel, which can achieve less carbon dioxide emissions and comply with the latest national five emission standards.

The industry believes that Dongfeng Fengshen's “e-TECO+STT gold combination” is the first of its kind to be applied comprehensively, highlighting the responsibility of Dongfeng Fengshen as a central enterprise brand and its scientific and technological strength. It will further promote the energy-saving automobile society and contribute to energy conservation and environmental protection.
