Wuling 474 and Chang'an The difference between 474 engines

1. The engine is a Japanese Suzuki engine. The old Chang'an Star is equipped with a purely imported 474, and now it is all nationalThere is nothing to say about the engine, but the body of Chang'an is worse than that of Wuling, and Wuling's B12 engine technology is still immature. If it is a 465 engine, you can choose Wuling Zhiguang.

2. The Wuling Hongguang 5L engine has DVVT technology, and the Chang'an Auchan 5L engine is made of all-aluminum material. In terms of power performance, the actual displacement of Chang'an Auchan is 5ml smaller, but the power and torque are slightly larger than that of Wuling Hongguang, that is, the power of Chang'an Auchan is higher.

3. At least the torque at low speed is not the third largest of the Chang'an 474 engine. The price of B12 series engine parts is more than twice that of 474 engine parts, and some commonly used parts are even more shockingly high.

What is the problem with the recent fuel consumption of the Chang'an Star 474 engine

1. The exhaust pipe has white smoke and high fuel consumption. It is recommended that you check the oxygen sensor. White smoke may be caused by the concentration of the mixed gas. The oxygen sensor is to correct the mixed gas. If the fuel consumption is high, it is recommended that you go to a regular 4S store to check and replace the spark plug cylinder wire, and then use the detector to check the signal fault code on the circuit.

2. The reason for the high fuel consumption of Chang'an Star 2: The fuel consumption during the running-in period is relatively high, and it is okay after passing. The fuel consumption of the new car during the running-in period should be about 100KM|8 fuel consumption.

3. If the fuel consumption is high after winter, it is because the weather becomes colder, the oil becomes thicker, and the resistance to gear operation increases, resulting in an increase in fuel consumption. If the winter oil is replaced after winter, the oil is relatively thin, which can alleviate the problem of high fuel consumption.

4. The appearance of this phenomenon is caused by the aging of the valve oil seal. Due to the decrease in temperature, the valve oil seal of the rubber valve oil seal is stiff and cannot be completely sealed. After the oil leaks from the valve into the combustion chamber, the above phenomenon occurs.

5. My Chang'an Star consumes a lot of fuel, and the cold car does not lead to speed. Many car enthusiasts may not believe in the oil route problem, but this problem exists in our country. In many cases, the damage to accessories is caused by premature aging of the oil route.

6. Step on the accelerator too hard: Many users are always anxious and always step on the accelerator when driving, especially when overtaking and starting. When stepping on the accelerator, the car makes a whimpling sound, that is, stepping on the accelerator too hard, which will cause the gasoline to not burn fully, resulting in gasoline It's a waste, and it's very fuel-consuming.

What is the engine of JL474QG

Chang'an Star S460, start Machine model JL474QG, displacement 1298mL, maximum power-power value 60kW, natural aspiration, environmental protection standard: national 3 Wuling Zhiguang2014 2L manual lengthened version, engine LD6, natural aspiration, maximum power 57KW, environmental protection standard: national four.

Blue whale engine. According to the official website of Chang'an Automobile, the jl473zq7 engine belongs to the Blue Whale engine under the Chang'an Automobile brand. Jl473zq7 is a new generation of NE5T high-pressure direct injection engine, with a maximum power of 138kw and a maximum horsepower of 188Ps.

jl473zq7 is the Blue Whale engine of Chang'an Automobile. The engine model jl473zq7 is the engine of Chang'an Automobile, which is the latest product of Chang'an Automobile Blue Whale Engine Platform. The engine is a 5-liter displacement four-cylinder turbocharged engine, with a maximum output of 188 horsepower and a maximum torque of 300 Nm.

How about the Chang'an Golden Bull Star 474 engine

1. Not bad. Chang'an Golden Bull Star 474 engine, naturally aspirated engine, powerful. It's easy to pull a ton of goods without pressure. Chang'an Golden Bull Star is a brand-new micro-car product developed by Chang'an Automobile to adapt to the new market environment, which is jointly created by designers from many countries.

2. The engine is strong. Chang'an Star 474 engine adopts advanced technology and design, with high power output and fuel economy. The engine is equipped with a larger cylinder capacity and cylinder pressure, thus providing greater power and torque.

3. JL473ZQ2 is better. The engine of the new Blue Whale engine jl473zq2 can achieve up to 5 fuel injections in one stroke.At present, it has the highest frequency of injection frequency among the models that have been mass-produced worldwide.

Chang'an Automobile 474 engine idle unstable throttle valve is a new spark plug is also a new situation_Baidu...

In addition, the idle valve body is dirty, the oil is too poor, the idle motor is not working normally, etc., which may cause the phenomenon of vehicle idle instability.

Check the exhaust manifold and ternary catalyst. The engine is high-voltage and the spark plug is normal, which can basically rule out the possibility of failure of the ignition system. If the air intake, exhaust and ignition are all normal, you can check the crankshaft tape wheel again. It is estimated that there is a high possibility of oil line problems. Test the fuel system oil pressure, pressure retention status, and fuel injection pulse width.

The reason for the high and low idling speed of the car may be: too much carbon accumulation in the throttle valve. Inlet manifold or various valve leakage.

The ignition system is mainly due to the high-pressure weak fire or the spark plug does not ignite, which directly affects the combustion of the cylinder, resulting in different cylinder power, resulting in unstable idling of the engine.

What kind of engine does 474 belong to

1. Origin: Wuling 474 engine is domestic, and Chang'an 474 engine used to have an imported version, and now it is also domestic. Models: Wuling 474 engine is mainly installed in Wuling Hongguang and other models, while Chang'an 474 engine is mainly installed in Chang'an Star and other models.

2. Nanjun Ruiyi engine is a model 474 engine of Wuling brand.This engine adopts a power of 45.

3. Chang'an Starlight. According to the inquiries of major public sales platforms, Chang'an Starlight 4500 adopts the engine JL474Q7, that is, the 474 engine. The JL474Q7 generator is an aluminum engine, which is lighter and has better heat dissipation.

4. OK. The Dongfeng Xiaokang 474 engine is equipped with the most advanced technology in the industry. The engine model LJ474 has a frequency of 1Hz and a rated power of 3kW and a rated voltage of 2V.

5. The engine is a Japanese Suzuki engine. The old Chang'an Star is equipped with a purely imported 474, and now it is all domestic. Needless to say, the engine is worse than that of Chang'an, and Wuling's B12 engine technology is still immature. If it is a 465 engine, you can choose Wuling Zhiguang.

6. Chang'an car 474 engine is Chang'an Star. Chang'an Star is a new model with a new concept in the field of microcars launched by experts from Chang'an and its international partner Suzuki in Japan for 4 years.
