Can the Audi A6L with dual-clutch transmission coast in neutral?

The Audi A6L with dual-clutch transmission cannot coast in neutral unless the owner does not want the transmission. The circulation and heat dissipation of transmission oil rely entirely on the rotation when in gear. Coasting in neutral stops this circulation. Introduction to coasting in neutral: During vehicle operation, the driver shifts the gear lever into the neutral position, separating the engine from the driven wheels' clutch, and uses the vehicle's inertia to continue moving. Coasting in neutral must be done under conditions that ensure safety and normal vehicle technical conditions. It is not allowed to coast with the engine off, especially when descending steep or long slopes. About fuel-saving claims when coasting in neutral: Automotive repair experts state that coasting in neutral does not save fuel and may sometimes consume more. This is mainly related to the working mode of electronically fuel-injected engines. Electronically fuel-injected engines can determine the amount of fuel injection based on computer programs. When in gear, if the driver releases the accelerator, the computer will put the vehicle into coasting mode, during which the engine does not inject fuel for a long period.

What are the symptoms of a faulty wheel speed sensor in the Mercedes GLS450?

The symptoms of a faulty wheel speed sensor in the Mercedes GLS450 include unstable engine idle, momentary stalling or engine shutdown when starting or decelerating to a stop, and reduced engine acceleration performance. Solutions for a faulty wheel speed sensor in the Mercedes GLS450 are as follows: External force damaging the wheel speed sensor wiring harness: In earlier models, particularly those before 2011, the wheel speed sensor wiring harness did not have extra length, which often led to the harness being pulled and damaged when the steering wheel was turned to its limit. This issue can be resolved by modifying the wheel speed sensor bracket to create additional length for the wiring harness, preventing future damage after replacement. False failure: Contamination of the sensor head or exposure to magnetic materials can cause the wheel speed sensor to malfunction. If the wheel speed sensor frequently fails after driving through water, mud, or sandy areas, it is likely due to dirt buildup and can be cleaned.

What transmission is used in the Changan Yidong manual transmission?

The transmission manufacturer used in the Mazda6 is the Japanese Mazda Motor Corporation. Mazda Motor Corporation, founded in 1920, officially began producing small trucks in Hiroshima in 1931 and started manufacturing passenger cars in the early 1960s. It has a very comprehensive product line, covering various models such as economy cars, SUVs, and sports cars, with family cars consistently dominating its production line. The Mazda6 uses a 6-speed manual transmission, 4-speed automatic transmission, 5-speed manual-automatic transmission, and 4-speed manual-automatic transmission. A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the driving wheels, enabling the car to achieve different traction and speed under various conditions such as starting, climbing hills, turning, and accelerating. When using the Mazda6's transmission in daily driving, pay attention to the following points: Do not delay changing the transmission oil for too long. Prolonged failure to change the transmission oil can damage internal components such as bearings and the housing. Avoid coasting in neutral for extended periods. While driving manual transmission models, many experienced drivers may coast in neutral, but for automatic transmission models, this can cause the transmission to overheat and produce a noticeable shock when shifting back into D gear. Never shift into D/R gear before the vehicle comes to a complete stop. Many drivers, to demonstrate smooth operation, shift into reverse gear while the vehicle is still moving, which can severely damage the transmission gears and lead to grinding or other faults over time. Avoid frequently climbing steep slopes in D gear. On steep inclines, automatic transmission vehicles may overheat due to high load or shift too early, resulting in insufficient power. In such cases, use manual mode to limit lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, use a flatbed tow truck to move it onto the tow platform while the vehicle is in N gear. Do not use a tow rope or tow the vehicle directly with another vehicle.

What is the fuel consumption of the Geely Boyue 2.0 engine?

Geely Boyue 2.0 has a total of 6 models, including the Boyue 2016 2.0L manual Zhilian, manual Zhishang, and manual Zhiyue models (3 variants), the Boyue 2018 2.0L manual two-wheel-drive Zhiya and manual two-wheel-drive Zhiyue models (2 variants), and the Boyue 2020 2.0L manual two-wheel-drive Zhiyue model (1 variant). All these models are equipped with a 141-horsepower engine, with an NEDC fuel consumption of 7.2L per 100 kilometers. The fuel tank capacities of different Geely Boyue 2.0 models vary, and the distance that can be covered on a full tank of fuel is as follows: For models equipped with the 141-horsepower engine and a fuel tank capacity of 60L, the distance is 60/7.2*100=833km. For models equipped with the 141-horsepower engine and a fuel tank capacity of 58L, the distance is 58/7.2*100=806km. 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 displacement engines generally consume more fuel than those with smaller displacement engines because larger displacement engines usually have 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 car resistance and fuel consumption. Low environmental temperature: When the engine block is cold, the injected gasoline does not atomize easily, requiring more gasoline to burn, which increases fuel consumption. Additionally, at low temperatures, the engine control unit may command higher idle speeds to warm up the engine, further increasing fuel consumption.

Where is the car fuel pump installed?

Fuel pumps are divided into gasoline pumps and oil pumps. The gasoline pump is installed inside the fuel tank, while the oil pump is installed inside the engine. The function of the gasoline pump is to draw gasoline from the fuel tank and deliver it through pipelines and fuel filters to the float chamber of the carburetor. It is precisely because of the gasoline pump that the fuel tank can be placed at the rear of the car, far from the engine, and below the engine. The working principle of the gasoline pump is as follows: 1. Currently, in most vehicle models, the fuel pump is installed inside the car's fuel tank and is electrically driven. The fuel pump consists of three parts: the pump body, the permanent magnet motor, and the housing. When the permanent magnet motor is powered, it drives the pump body to rotate, sucking fuel from the inlet, passing it through the internal structure of the electric fuel pump, and then pressing it out from the outlet to supply the fuel system. The fuel flowing through the electric fuel pump also cools the armature of the permanent magnet motor, hence it is also known as a wet fuel pump. 2. The motor part of the electric fuel pump includes a permanent magnet fixed on the housing, an armature that generates electromagnetic torque, and a brush device installed on the housing. The brushes are in contact with the commutator on the armature, and their leads are connected to the terminals on the housing, directing the voltage that controls the electric fuel pump to the armature windings. The ends of the electric fuel pump housing are crimped and riveted, assembling all components into a non-detachable unit.
