Does idling the car consume more fuel?

Idling the car does consume more fuel. The main reasons for increased fuel consumption are: 1. Spark plugs: Spark plugs are the key component for igniting the air-fuel mixture in the cylinders. Poor performance or aging of spark plugs will inevitably lead to engine fatigue and increased fuel consumption. 2. Rapid acceleration: Quick acceleration while driving causes strong friction between the tires and the ground, accelerating tire wear and increasing fuel consumption. 3. Prolonged idling without turning off the engine: Compared to normal driving, the engine ECU controls a higher fuel injection volume when the car is idling or just started. If the engine is not turned off or frequently idles for long periods, fuel consumption will increase.

How to adjust the air conditioning in the Changan Eado?

To adjust the air conditioning in the Changan Eado, follow these steps: 1. Enter the car and locate the air conditioning control area in the center. The A/C button is the air conditioning cooling switch, and the MAX A/C button maximizes cooling. 2. The left knob adjusts the temperature, while the right knob controls the air volume. 3. The "AUTO" button turns on the automatic air conditioning. Press the car icon button to activate the internal circulation when needed. 4. Use the defogging function when the front windshield fogs up, and activate the rear windshield heating in rainy weather.

Is the 2019 Corolla a Three-Cylinder or Four-Cylinder?

The 2019 Corolla lineup exclusively uses four-cylinder engines. Here are some details about the 2019 Corolla's engines: 1. This model was available in both gasoline and hybrid versions. The gasoline version is equipped with a 1.2T turbocharged engine, while the hybrid version uses a 1.8L naturally aspirated engine. 2. There isn't a significant difference in performance between three-cylinder and four-cylinder engines, mainly just structural differences. Compared to a four-cylinder engine, a three-cylinder engine has one less cylinder.

What does 200cc and 400cc mean?

200cc and 400cc refer to the displacement of motorcycles. 200cc means a displacement of 200 milliliters, while 400cc means a displacement of 400 milliliters. The difference between the two is that 400cc has a larger displacement than 200cc, and the engine power, performance, and fuel consumption of 400cc are all greater than those of 200cc. The differences between car displacements of 1.5T and 1.6T are as follows: 1. Different nature: 1.6L is a displacement of 1.6 liters, where L stands for long, and 1.6T is a 1.6L engine with turbocharging; 2. Different fuel consumption: 1.6L has lower fuel consumption; 3. Different power: 1.6T has greater power and performance; typically, a turbo can increase the base power by about 10%-30%, and some can even exceed 50%. 1.6T can deliver greater power and torque, even comparable to a 2.4L naturally aspirated engine; 4. Different maintenance costs: 1.6T has higher maintenance costs. The difference between 1.6L and 1.6T is that 1.6T comes with a turbocharger, resulting in lower fuel consumption, greater power, and relatively higher maintenance costs compared to 1.6L.

Will the car shake badly if the shock absorbers are too soft?

Yes, if the shock absorbers are too soft, the car will shake up and down significantly. Here is the relevant information: 1. Car Suspension: The damping system of a car's suspension is similar to the shock absorbers on a mountain bike, with the same basic principle. The damping effect depends on the size of the damping force. A suspension with high damping (large damping force) is too stiff, providing strong support. When driving over bumpy roads like small mounds, the car won't experience significant rigid impacts, but it will feel slight bumps on small potholes. Conversely, a suspension with low damping (small damping force) is too soft, producing the opposite effect. Traditional suspensions adopt a design principle that balances both damping and support but cannot optimize both performances simultaneously. 2. Magic Carpet Suspension: This technology has obtained 20 patents, does not require electric drive, and does not add extra energy consumption. The new technology adds a progressive hydraulic buffer at both the upper and lower ends of each shock absorber, allowing the car to adjust its damping according to road conditions, ensuring comfort under different road conditions. The PHC adaptive hydraulic stabilization technology enables the suspension to switch to a low damping range on relatively smooth roads (minor bumps), greatly reducing the bumpy feeling. On severely bumpy roads (major bumps), the suspension can increase its damping force, effectively absorbing mechanical energy and avoiding discomfort caused by rigid impacts, achieving damping effects and thereby realizing the magic carpet effect.
