Why is the fuel consumption of Hongqi H5 high?

1 Answers

Hongqi H5 has a combined fuel consumption of 6.2-6.4L/100km. Currently, there are 6 models of Hongqi H5 available for sale: the DCT Qiyue Edition and DCT Qiyun Edition, with a combined fuel consumption of 6.2L/100km. The Automatic Zhilian Qiyun Edition, Automatic Zhilian Qichang Edition, Automatic Zhilian Qiling Edition, and Automatic Zhilian Qixiang Edition have a combined fuel consumption of 6.4L/100km. The above figures are the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, around 8.0L. Specific factors affecting car fuel consumption are as follows: Car weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV weighing about 1.5 tons has a fuel consumption of about 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag, leading to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point where fuel consumption is minimized. Generally, small-displacement cars reach this point at around 70 km/h, while larger-displacement cars achieve it at about 100 km/h. Maintaining speed within this economical RPM range results in the least fuel consumption. Driving style: Aggressive driving behaviors such as rapid acceleration, frequent overtaking, and not easing off the throttle before red lights can increase fuel consumption.

How Far Can You Drive After the Fuel Gauge Light Comes On?

When the fuel gauge light comes on in a car, you can typically drive about 20 kilometers. The light indicates that the vehicle's fuel level is low and requires refueling. Here are the recommended actions to take when the fuel gauge light comes on: 1. Maintain a reasonable speed; 2. Reduce the vehicle's load; 3. Avoid using the air conditioning; 4. Close windows to minimize wind resistance; 5. Choose smooth road conditions to reduce bumps and maintain steady speed; 6. Drive smoothly to avoid unnecessary braking; 7. Avoid congested routes. Additionally, here are some tips for refueling: 1. Refuel in the morning or evening to avoid direct sunlight at noon; 2. Fill up with fresh fuel before long trips; 3. Do not exceed the fuel tank's maximum capacity.

What is the reason why the rear door of BMW X2 cannot be opened from the inside?

BMW X2 rear door cannot be opened from the inside possibly because the child lock is in the activated state. The specific reasons are as follows: 1. Child lock is activated: You need to take out a flat-head screwdriver and turn the child lock to the off position. 2. Door lock block cable failure: After this reason occurs, the door cannot be opened from the inside because the cable failure directly affects the lock block not opening. 3. Door hinge and lock pillar deformation: When the door is subjected to a certain external force, it may cause the door hinge and lock pillar to deform, which is also one of the reasons why the door cannot be opened. 4. Door limiter failure: Replace with a new door limiter, so the door can open and close smoothly. 5. Door frozen: In winter, the weather is relatively cold, and the door can easily freeze.

What is the tire size of the Peugeot 207?

The Peugeot 207 has two tire specifications: Kumho 185/65-R14 and Kumho 185/6-R15. Here is some extended information about tires: 1. The main functions of tires are to support the entire weight of the vehicle, bear the load of the car; transmit traction and braking torque, ensuring the adhesion between the wheels and the road; reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components, adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. 2. Each tire tread groove has a wear limit indicator, which is 2mm thick. It is recommended to replace the tires when the tread thickness wears to 4mm from the limit indicator or 6mm from the deepest part of the groove.

What Causes Fluctuating Engine Oil Pressure?

Fluctuating engine oil pressure can be caused by the following reasons: 1. Faulty oil pump (e.g., excessive gear wear or loose fixing screws), causing the oil pump to suck in air. 2. The regulating valve or return valve spring is stuck by foreign objects, or the spring is bent and rubs against the seat hole, hindering the spring's movement and making it difficult for the ball valve to open and close. 3. Insufficient oil in the oil pan, with the oil level at the limit position of the oil strainer suction port, or impurities in the oil pipe that are not completely blocked, causing the oil pump to intermittently suck oil and resulting in fluctuating oil pressure. 4. Improper assembly or sticking of the pressure relief valve, causing unstable oil flow resistance, or a damaged oil pressure gauge can also lead to fluctuating oil pressure.

What are the reasons why the remote control door cannot be opened?

Generally, there are two possibilities: the car battery is low on power, or the key in your hand is out of battery. In this case, no matter what subsequent steps are taken for handling or repair, we first need to use the spare mechanical key to open the car door. First, check whether the indicator light on the remote flashes when unlocking. If it does not flash, the problem lies with the remote itself. If it flashes but the vehicle's central control does not respond, troubleshoot the unlocking circuit of the central control lock. The solutions are as follows: ① Use the key to lock the driver's door and check if other locks are engaged. ② Remove the main driver's door panel and inspect whether the electromagnetic lock inside is in the correct position. ③ Check if there is any issue with the metal rod inside the car door.

Will the Engine Bay Get Wet During Car Washing?

Washing the engine bay will get it wet. During car washing, water inevitably enters the engine bay through gaps between the engine hood and the car body. Although water does seep into the engine bay through these gaps, the amount is minimal, so there's no need to worry. More details are as follows: 1. Even if a significant amount of water enters the engine bay, there's no cause for concern. The engine bay can be cleaned, and it's recommended to do so approximately once a year. Cleaning the engine bay has only benefits and no drawbacks. 2. If the engine bay is too dirty, it can oxidize the surfaces of rubber and plastic components, leading to related circuit short circuits. It can also impair the engine's cooling function, increasing fuel consumption and causing unnecessary waste. 3. However, one important point to note when cleaning the engine bay is to avoid letting water enter the wiring, as this could cause short circuits. Special attention should be paid to areas like the ignition coils, the fuse box, and behind the headlights.
