Should the clutch and brake be pressed together when parking?

Pressing both the clutch and brake together when parking is only applicable in emergency braking situations. The purpose of this is to prevent misoperation. In an emergency, there is a high possibility of mistakenly operating the pedals due to panic. If both the brake and clutch are pressed simultaneously at this time, even if the accelerator is mistakenly pressed, it will not affect the braking effectiveness. Additionally, not pressing the clutch may cause the engine's drag torque to interfere with the normal operation of the ABS system. In severe cases, it could also affect overall vehicle control and the effectiveness of emergency avoidance maneuvers, making it even more dangerous on slippery roads. In an emergency, you should firmly hold the steering wheel with both hands, observe the situation ahead, and quickly and decisively press the brake pedal with your right foot all the way down, but do not rush to press the clutch. This is because when the vehicle speed has not yet dropped to a certain level, the engine also provides some deceleration effect. Moreover, pressing the clutch too early and creating a neutral gear will leave the vehicle in an uncontrolled state, making it difficult to take other remedial measures such as steering. The clutch should only be pressed when the vehicle speed drops to the point where it is about to stall.

Does driving a car in water have any impact?

Driving a car in water does have an impact. When the exhaust pipe is submerged, the exhaust resistance increases significantly. Additionally, the resistance of the car moving through water itself is considerable, causing the engine speed to drop rapidly and leading to stalling. Here are some methods to identify flood-damaged and accident vehicles: 1. Check the car locks: Look for signs of being pried open, damaged, or filled with glue. Then use the key to open each door to see if the locks are from the same set and if each door lock can be turned easily. Note that if turning the key is very difficult or requires almost breaking the key to open, it might be due to flood damage causing the central control motor to rust and malfunction. 2. Engine compartment: Inspect the mounting brackets of the lighting and signal lamp groups in the engine compartment for breakage or looseness. Check the wire connectors and sockets; if there is a large amount of sediment or rust spots inside, it may indicate a flood-damaged vehicle. 3. Engine compartment inspection: Examine the wiring and vacuum pipes on the engine body, as well as the gaps between the high-voltage ignition coils and spark plugs for traces of mud. Assess whether the aging and cracking of the pipes and wiring match the car's age and check the condition of the fuel injector mounts. The presence of rust on springs can also help determine the likelihood of the car being flood-damaged.

What is the fuel consumption of the Edge Plus?

The fuel consumption of the Edge Plus is 13.7-14.7L/100km. The currently available Edge Plus models include six variants: the 2021 PLUS-EcoBoost245 4WD Zunrui, 2WD Jingrui, 2WD Borui, 2WD Haorui, 2WD ST-Line, and 4WD ST-Line. The official NEDC combined fuel consumption is slightly lower than the actual consumption, ranging from 8.1-8.6L/100km. Among vehicles in the same class, the Haval H9 has an NEDC combined fuel consumption of 9.9L/100km, the BMW X1 ranges from 6.1-9.2L/100km, the Tayron consumes 6.7-7.5L/100km, the Envision has 6.7-7.5L/100km, and the Volkswagen L also shows 6.7-7.5L/100km. Automobile fuel consumption is directly influenced by five major factors: driving habits, the vehicle itself, road conditions, natural wind, and ambient temperature. Details are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before traffic lights increase fuel consumption. The vehicle itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because higher displacement typically means greater power output, requiring more gasoline for combustion. Heavier vehicles also have higher fuel consumption due to the need for greater driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous terrain increases resistance and fuel consumption. Natural wind: Headwinds or driving on windy days increase vehicle resistance and fuel usage. Low ambient temperatures: When the engine block is cold, injected gasoline does not atomize easily during cold starts, necessitating more fuel for combustion, which increases consumption. Additionally, lower temperatures prompt the engine's computer to use higher idle speeds to warm up the vehicle, further raising fuel consumption.

What Are the Engine Arrangement Types?

Engine arrangement types include: 1. L-Type: Also known as inline engines, where cylinders are arranged in a straight line, aligned side by side at the same angle in a single plane; 2. V-Type: Divides all cylinders into two groups, arranging adjacent cylinders at a certain angle to form two planes with an angle between them, appearing as a 'V' shape from the side; 3. H-Type: Also called horizontally opposed engines, a variant of V-type engines where the angle is extended to 180 degrees; 4. W-Type: A proprietary engine technology of Volkswagen Group, combining two V-type engines to form another V-type engine.

Is the DCT Transmission Dry or Wet?

DCT transmissions are divided into two types: dry and wet. More information about these two types of DCT transmissions is as follows: 1. Dry clutch: The advantages are lower manufacturing cost, lower selling price, and high mechanical transmission efficiency; the disadvantages are that operation requires mastering the essentials, the operation process is relatively troublesome, resulting in a high failure rate. 2. Wet clutch: It requires the design of a hydraulic coupler or torque converter, used in conjunction with the clutch for flexible power connection. The advantages are easy operation and low failure rate. The disadvantages are high manufacturing cost, higher selling price, and low mechanical transmission efficiency.
