How to Deal with Fogging on the Outside of the Front Windshield When Driving in Summer Rain?

Turn on the air conditioning and direct it to blow onto the front windshield. The cold air will quickly disperse the fog, providing a fast and direct solution. Using hot air to blow on the glass can also effectively remove the fog. You can use the windshield wipers directly, but remember to spray water while wiping to avoid dry wiping. Before heading out, simply spray it evenly on the surface of the car window glass and wipe it clean with a dry towel.

What to Do When the Nissan X-Trail Does Not Detect the Key?

If the keyless entry system displays "Key not detected," you can place the chip key against the keyless button and then start the ignition, which should generally allow the engine to start. When the vehicle control panel displays "Key not detected," it may indicate that the key battery is dead, and you should promptly replace it with a new large coin cell battery. If the keyless start system fails to activate, it might be because the key is too far from the ignition switch. It is advisable to place the key in the storage slot in front of the center console. For vehicles with keyless start systems, it is essential to protect the key carefully. Avoid frequent dropping, exposure to moisture, or demagnetization to prevent damage.

How Many Cylinders Does the Chevrolet Malibu XL Engine Have?

The Chevrolet Malibu XL is equipped with a 4-cylinder engine. The engine model is LFV, with a maximum power of 124kW, maximum torque of 250Nm, and maximum horsepower of 169Ps. The Malibu XL's engine is produced at the Shanghai Pudong Jinqiao plant and is an in-house engine of Shanghai General Motors. Here are some daily maintenance methods for the Chevrolet Malibu XL's engine: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, which can cause various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil, but in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

What is the fuel consumption of the Terra?

The Terra has 6 models currently on sale. Among them, the 2020 2.5L XV Automatic 2WD Zhixiang Edition and XL Upper Automatic 2WD Luxury Edition, both equipped with a 193 horsepower engine, have an NEDC fuel consumption of 9.2L per 100 km. The 2020 2.5L XL Upper 4WD Automatic 4WD Luxury Edition and XV 4WD Automatic 4WD Flagship Edition, also equipped with a 193 horsepower engine, have an NEDC fuel consumption of 9.6L per 100 km. The 2020 2.5L XE Manual 2WD Elite Edition and XL Manual 2WD Leading Edition, both with a 193 horsepower engine, have an NEDC fuel consumption of 8.9L per 100 km. The fuel tank capacity is the same across all Terra models. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 193 horsepower engine and NEDC fuel consumption of 9.2L, 9.6L, and 8.9L per 100 km, the fuel tank capacity is 73L. The distance that can be covered with a full tank is 73/9.2*100=793 km; 73/9.6*100=760 km; 73/8.9*100=820 km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power output, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during a cold start, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer controls a higher idle speed to warm up the engine, which also increases fuel consumption.

Where are the VIN and Engine Number Located?

Locating the Engine Model: The engine model can be found on the outer surface of the engine block, vehicle registration certificate, vehicle license, purchase invoice, factory certificate, operation certificate for commercial vehicles, vehicle purchase tax payment certificate, registration with public security authorities, vehicle insurance card, and the actual engine (usually on the engine nameplate). The engine number, like a person's ID number, represents each vehicle and contains crucial information about it. Locating the VIN: The VIN can be seen on the vehicle's production nameplate. The Vehicle Identification Number is the same as the VIN. It can also be found on the inner side of the windshield near the driver's seat, consisting of letters and numbers. Opening the engine hood will also reveal the VIN in the engine compartment. The VIN, or Vehicle Identification Number, is a designated code created by manufacturers to identify vehicles. The VIN is stamped on the vehicle's frame. The exact location varies by manufacturer, so refer to your vehicle's manual for specifics. Engine models are identification codes assigned by manufacturers according to regulations, industry practices, and engine attributes. These codes indicate details like the manufacturer, specifications, performance, features, technology, purpose, and batch of the engine, including fuel type, cylinder count, displacement, and static brake power. Engines installed in passenger cars or multi-purpose vehicles must display the manufacturer, model, and production number as required. The VIN, commonly referred to as the frame number, is technically the Vehicle Identification Code, a unique alphanumeric sequence assigned by the manufacturer. The VIN consists of 17 characters, also known as the 17-digit identification code, frame number, or 17-digit number. The combination of these characters ensures that no two vehicles of the same model will have the same number within 30 years, making it a unique identifier akin to a 'vehicle ID card.' Common locations include the vehicle license and the lower left side of the front windshield. Note that the engine number is not the same as the engine model. The engine model refers to the specifications and size within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, is a unique production code assigned to each individual engine. Engine Number Composition: Front Section: Includes product series code, generation symbol, and regional or manufacturer code, chosen by the manufacturer but standardized and registered with the relevant industry authority. Middle Section: Comprises symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Rear Section: Includes symbols for structural and usage characteristics. End Section: A distinguishing symbol. Manufacturers may add symbols to differentiate improved versions, separated from the rear section by a hyphen if needed. The VIN consists of 17 characters divided into three parts. Part 1: WMI—World Manufacturer Identifier (positions 1-3); Part 2: VDS—Vehicle Descriptor Section (positions 4-9); Part 3: VIS—Vehicle Identifier Section (positions 10-17).
