The engine is the core of the three parts of an automobile. China automobile industry started late, and engine technology has always been a heart disease. 2/kloc-0 At the beginning of the century, many domestic independent brands believed in "takenism", either purchasing engines directly from foreign brands or developing and producing engines in reverse. In short, the core technology is in the hands of others. As a recognized independent brand "technical house", Chery focused on the active research and development of engines as early as 2002. Through in-depth cooperation with foreign advanced engine companies, the first ACTECO engine with independent intellectual property rights was launched, which led to the upsurge of independent brand engines.

After more than ten years of development, independent brands have used their own engines designed and manufactured. Take the most common 1.5T engine for family cars at present, each family has its own core technology. Among them, the ACTECO second generation 1.5T engine equipped with Chery Arrizo 5 PLUS is the most representative. Not only won the title of "Top Ten Engines in China", but also successfully exported to overseas markets. At the same time, this engine also matches the unique 9-speed CVT continuously variable transmission of the same class, and its overall performance is excellent. Therefore, Chery Arrizo 5 PLUS can be said to be the first choice at the same level.

There is nothing to say. As a "technical house", Chery always speaks with strength. Next, let's take a look at why Arrizo 5 PLUS is the first choice at the same level.

First, collect civil and military power.

Arrizo 5 PLUS is equipped with ACTECO II 1.5T engine and CVT gearbox which can simulate 9 speeds. Because the transient response time of the turbocharger of this engine is 35% longer than that of the transmission turbocharger, when the engine speed is 1250 rpm, the turbocharger has already started to work, and the steady-state torque of 210n m can be output at 1750 rpm. The peak torque of 230n·m can be achieved between 2000 and 4000 revolutions. It has good low torque characteristics and wide peak torque output range, which can bring a dense "push back feeling" to drivers. At the same time, the thermal efficiency of this engine is as high as 37. 1%, which was once in the leading position in China. It is not only powerful, but also excellent in fuel economy. Such a power system with both civilian and military functions must be very complicated. Next, let's see how much "black technology" Chery has given them.

Second, leading the engine technology at the same level.

1. Integrated exhaust manifold

The integrated exhaust manifold structure integrates the exhaust manifold of the engine into the cylinder head of the engine, which has the advantage of reducing the distance between the exhaust gas and the turbine, not only improving the utilization efficiency of exhaust gas energy, but also improving the warm-up efficiency of the engine, thus reducing fuel consumption. It is worth mentioning that BMW's brand-new B48 engine also adopts this design.

2. Integrated intake air cooling

The integrated intake intercooler structure combines the intake manifold of the engine with the intercooler. Its advantage is that it can effectively reduce the pressure loss of pressurized air and improve the response speed of the engine. At the same time, rapid air intake can quickly take away the heat of coolant and improve the cooling efficiency of intercooler.

3. A new generation of high-efficiency turbocharger

Chery's new generation of high-efficiency turbocharger adopts electronic actuator and supercharge slimming technology. The former makes the turbine have higher control accuracy and more sensitive response speed, while the latter optimizes and upgrades its structure while ensuring the efficiency of the turbine. This two-pronged approach can not only effectively restrain turbine lag, but also help reduce fuel consumption and emissions.

4. Electronic control thermostat

Different from our common mechanical thermostat, Chery's 1.5T engine adopts an electronic thermostat, which controls the flow of coolant by monitoring the engine temperature in real time, so as to quickly raise the oil temperature and achieve the effect of rapid warming-up, thus reducing fuel consumption.

5.DVVT variable valve timing technology

DVVT variable valve timing technology can adjust the valve closing timing according to different working conditions of the engine, so that the mixture can reach the most suitable air-fuel ratio (air-fuel ratio), thus improving the power performance and fuel economy of the engine.

Chery's advanced engine technology is far more than that. The second generation 1.5T engine of ACTECO of Arrizo 5 PLUS is equipped with these advanced technologies, so it has excellent fuel efficiency of 37. 1%. Its fuel consumption per 100 kilometers is as low as 6.8L, which also meets the national six emission standards. It is a veritable "strongest Chinese core".

Third, excellent transmission performance.

Arrizo 5 PLUS is equipped with China's first 9-speed CVT continuously variable transmission, which was once rated as "Top Ten Transmissions in the World". It adopts a new type of high-efficiency vane pump, a new type of hydraulic torque converter, a new type of hydraulic system and a new type of steel belt, which breaks through many technical barriers of CVT and is a well-deserved "light of domestic products". So what are its outstanding performances?

1, with high transmission efficiency.

This CVT transmission adopts a brand-new structural design and compact layout, which can reduce the pump oil loss by more than 30% and greatly improve the transmission efficiency.

2. High fuel economy

Due to the adoption of high-efficiency hydraulic components, low-speed locking torque converter, new hydraulic system and new steel belt, the transmission has achieved the best matching with the engine working conditions and effectively reduced the engine fuel consumption.

3. Good comfort and handling.

Thanks to the structural advantages, CVT can fundamentally avoid the sense of frustration caused by shifting, and has good acceleration and deceleration smoothness, thus bringing a comfortable driving experience. In addition, this transmission adopts an independent hydraulic circuit, so the control accuracy and response speed will be faster than similar products. In addition, it can also simulate 9 gears, which can bring handy control fun to drivers.

Four. Reliable quality assurance

Providing lifetime warranty service for ACTECO II 1.5T engine equipped on Chery Arrizo 5 PLUS not only makes consumers feel more at ease, but also shows that Chery has enough confidence in the quality of this engine.

The parts suppliers of Arrizo 5 PLUS are world-renowned brands, such as Schaeffler's engine accessory gear train, Eaton's intake and exhaust valves, Federal-Mogul spark plugs, Valeo's clutches and so on. The addition of well-known brands also makes this power system more mature and durable, and the quality is more guaranteed.

abstract

After reading these, you should understand why Chery Arrizo 5 PLUS is the first choice at the same level, because it relies on excellent technical strength, rather than grandiose propaganda and touting. Chery, the "technical house", is always used to speaking with strength, and Arrizo 5 PLUS is like a treasure boy. I didn't know so well until I got to know it carefully. Today, Chery Arrizo series products have been exported to more than 80 countries and regions, with more than 700,000 users worldwide. Such excellent sales performance just confirms the old saying: the fragrance of wine is not afraid of the depth of the alley, and good products will always be recognized by the world.
