Phenomena of a blown car cylinder head gasket: 1. Burn damage between the cylinder edges of the gasket: The engine lacks power, the car feels weak when driving, has poor acceleration. When removing the air filter, a "popping" sound can be heard at the intake pipe opening during engine idle. 2. Burn damage connecting to the water jacket hole: The radiator bubbles and boils over, and white smoke appears in the exhaust. 3. Burn damage connecting to the oil passage: Some engine oil may enter the cylinder and burn off, resulting in blue smoke in the exhaust. 4. Burn damage connecting to the external atmospheric environment: The engine has poor performance, reduced fuel efficiency, and emits intense popping sounds from the damaged area of the gasket.

Why does flashing the program improve power?

After flashing the program, the reason for the power improvement is: the turbo pressure of the turbocharged engine increases, the fuel injection volume increases, and more air and gasoline enter the combustion chamber to do work, thus improving the power. The following is the relevant information about flashing the program: 1. Flashing the program for a car means updating the program in the ECU car computer to meet performance requirements, including increasing power or saving fuel, or even adding new functions. Flashing the first stage of a car refers to keeping the hardware unchanged and improving power by changing the ECU software parameters. 2. After flashing the program, fuel consumption will also increase. Because the increase in power requires more air and gasoline to participate in combustion, resulting in increased fuel consumption.

How to Shift a Serpentine Gear

Shifting a serpentine gear is not much different from shifting a straight-line gear. The shifting method for a serpentine gear is as follows: 1. For turning off the engine and long-term parking, shift to "P" gear and engage the handbrake. 2. For moving forward, shift to "D" gear. For safety, you should press the brake when shifting to "D" gear, and then slowly release the brake after shifting. At this time, due to the power output, the car will move forward slowly even without pressing the accelerator. Some cars have D3, D2, D1, L, or S gears after "D" gear, the principle of which is to limit the automatic transmission from shifting to higher gears. 3. When the speed and RPM are not high, you can switch between "D" and "D3" gears without stopping the car. 4. For reversing, shift to "R" gear. Similarly, you should press the brake to shift, and switching between "D" and "R" should only be done when the car is completely stopped to avoid damaging the transmission. 5. For neutral and short-term parking, shift to "N" gear. "N" is only a transition between "D" and "R". For example, when waiting at a red light, parking for less than half a minute does not require shifting to "N" gear; just stay in "D" gear and press the brake. For parking for one or two minutes, shift to "N" gear and engage the handbrake. For parking for four or five minutes or longer, shift to "P" gear and turn off the engine.

Does the intake tract need cleaning?

The intake tract does need cleaning. Due to various issues such as fuel quality, a significant amount of carbon deposits can accumulate in the intake tract after the engine has been running for a period of time. If the intake tract is not cleaned, it can lead to sluggish acceleration, difficulty starting the car, or even failure to start. Over time, it can also cause wear on the throttle valve and choke plate, resulting in unstable engine idling. Below is some relevant information about the intake tract: 1. There is no fixed interval for cleaning the intake tract; it is generally cleaned along with the intake system, with the specific timing determined by various factors such as driving habits, the vehicle's operating environment, and the control method of the fuel injection system. 2. If the vehicle is primarily driven in urban areas, it is recommended to clean it every 20,000 to 30,000 kilometers. If the car is often driven in environments with poor air quality, the intake tract can get dirty more easily, which over time can affect the engine's air intake and lead to difficulty starting the car. In such cases, it is advisable to clean it earlier than usual.

Automatic Transmission Uphill Parking Tips

When parking an automatic transmission vehicle on a slope, first engage the handbrake, press the foot brake to shift into N gear, then shift into P gear. Drivers need to pay attention to whether the vehicle may roll back when parking on a slope to avoid causing damage. Below are related introductions to slope parking: 1. Downhill roadside parking: When parking on a downhill road, if there is a curb, bring the right front wheel of the car close to or near the curb to prevent the car from sliding down the slope. If there are no curbs on either side of the road, increase the angle of the front wheels to avoid the vehicle sliding into the center of the road, which could cause unnecessary damage. 2. Uphill roadside parking: When parking on an uphill road, also control the steering wheel properly to prevent the vehicle from rolling back during parking, which would compromise safety and could result in financial losses.

What is the fuel consumption of the BMW X5?

BMW X5-2.0T average fuel consumption: 10.5L/100km, BMW X5-3.0T average fuel consumption: 13.3L/100km, BMW X5-4.0T average fuel consumption: 15.3L/100km. The BMW X5 is the first four-wheel-drive SUV model under the BMW brand. Below is an introduction to fuel consumption: 1. According to the vehicle's onboard computer. Generally, higher-end vehicles are equipped with an onboard computer that displays instant fuel consumption and average fuel consumption. To calculate fuel consumption accurately, clear the data in the computer and read the average fuel consumption. 2. First, when refueling, fill up until the pump automatically stops (jump gun), and do not add more fuel. Record the current mileage. After driving for a period, when refueling again, fill up until the pump automatically stops (jump gun) and do not add more fuel. Record the amount of fuel added and calculate the distance traveled since the last refueling. Divide the fuel amount by the distance to get the fuel consumption. Since the car's fuel tank size is fixed and the fuel pump nozzle is standardized, filling up to the jump gun ensures a consistent fuel level in the tank, making this method the most accurate for calculating fuel consumption.

What is the actual fuel consumption of the Tiggo 8 Plus?

The fuel consumption of the Tiggo 8 Plus is 6.8L/100km. The fuel consumption of a car varies slightly depending on each individual's driving habits and skills. A smoother driving habit results in lower fuel consumption, while aggressive driving, frequent overtaking, and other high-RPM operations will appropriately increase fuel consumption. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. If the air conditioning cooling effect is poor, it will increase fan speed and lower temperature to achieve a cooling effect. 2. Frequent hard braking: Frequent hard braking is the main reason for high fuel consumption in cars. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside the car. After the vehicle has cooled down moderately, then turn on the air conditioning.
