What are the reasons for the Roewe i5 engine emission failure?

Reasons for the Roewe i5 engine emission failure: Decreased engine performance. The following are the causes of reduced engine performance: 1. Clogged catalytic converter: A clogged catalytic converter can lead to poor exhaust flow, reduced power, and increased fuel consumption. In severe cases, it may cause engine shaking or even stalling. 2. Dirty air filter: A dirty air filter can result in insufficient air intake, reducing the car's power and increasing fuel consumption. More importantly, it can directly cause the throttle valve to become dirty and accumulate carbon deposits. 3. Faulty spark plugs: Faulty spark plugs can cause the car to idle roughly, significantly reduce power, and increase fuel consumption. 4. Carbon deposits on fuel injectors: Carbon deposits on fuel injectors can lead to insufficient engine power, rough idling, difficulty starting, and increased fuel consumption. The main causes of clogged fuel injectors are carbon deposits from the engine or impurities in the fuel. 5. Carbon deposits on the throttle valve: Carbon deposits on the throttle valve are a major factor affecting its operation. Not cleaning the throttle valve for a long time can cause errors in its opening angle and allow air with impurities to enter the engine cylinders, leading to abnormal engine operation.

What does car mileage mean?

Car mileage, also known as kilometers driven, refers to the distance a vehicle has traveled. The vehicle mileage is related to the specific kilometers driven by the vehicle and serves as a reference data for vehicle maintenance as well as for the sale of used cars. The speedometer is equipped with both a total mileage counter and a trip mileage counter. The total mileage counter records the cumulative distance the car has traveled, while the trip mileage counter records the distance traveled on a single trip. The trip mileage counter can be reset to zero at any time. The total mileage represents all the distance the vehicle has traveled since it left the factory and generally cannot be altered by the owner; specialized equipment is required to modify it. Mechanical odometers obtain their speed signal from the rear end of the transmission output shaft. The method involves the transmission output shaft driving an odometer gear that rotates synchronously with the output shaft. This gear then drives a flexible cable, the other end of which is connected to the odometer. According to a preset ratio, it drives the odometer counting gear to rotate, thereby calculating the car's mileage data. Electronic odometers feature a display screen where the parameters shown are controlled by the vehicle's onboard computer. The speed sensor transmits the wheel rotation speed signal to the onboard computer, which calculates a value based on pre-stored programs and displays it on the dashboard, continuously updating as the car moves.

What is the fuel consumption of the Audi A6L 3.0T?

The Audi A6L 3.0T has four models currently on sale, including the Audi A6L-2022 55 TFSI quattro Premium Dynamic, Premium Elegance, Flagship Dynamic, and Flagship Elegance models. These four models equipped with a 340-horsepower engine have an NEDC fuel consumption of 8.0L per 100 kilometers. The fuel tank capacity is the same for different models of the Audi A6L 3.0T. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 340-horsepower engine, the fuel tank capacity is 73L. The distance that can be covered with a full tank is 73/8.0*100=913km. 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 encountering a red light, will 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, requiring more gasoline for combustion. Cars with greater weight will also have higher fuel consumption because more torque is needed to drive them. 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 is less likely to atomize during cold starts, requiring more gasoline for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What is the actual fuel consumption of the Leiling Hybrid?

The comprehensive fuel consumption of the Leiling Hybrid is 4.0-5.7L/100km. There are currently 13 models of the Leiling Hybrid on sale, including the E-CVT JinQu (Advance) Edition, E-CVT HaoHua (Luxury) Edition, E-CVT KeJi (Technology) Edition, E-CVT LingXian (Leading) Edition, and E-CVT ZunXiang (Premium) Edition, with a comprehensive fuel consumption of 4.0L/100km. The E-CVT YunDong (Sport) Edition has a comprehensive fuel consumption of 4.2L/100km. The above figures are the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 4.8-5.3L/100km. The specific factors affecting car fuel consumption are as follows: Car weight: The larger and heavier the car, the higher the fuel consumption. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of about 7.5 liters (calculated under full load), while an SUV model weighing about 1.5 tons has a fuel consumption of 8.5 liters. Different weights lead to different fuel consumption. Drag coefficient: The higher the drag coefficient, the more fuel the car consumes while driving. If the car has a better streamlined shape, the drag coefficient is lower, resulting in lower fuel consumption. Economical RPM: During driving, the engine has a most economical torque output point. As long as the car's speed remains within this torque output point for a long time, the fuel consumption will be greatly reduced. Generally, small-displacement cars have an economical RPM at about 70 km/h, while large-displacement cars have it at about 100 km/h. Maintaining the speed within this economical RPM range ensures the least fuel consumption. Driving style: Aggressive driving, such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when encountering a red light, will increase fuel consumption.

What is the conventional range of a gasoline-powered car?

The conventional range of a gasoline-powered car is generally over 500 kilometers. Below are the detailed explanations: 1. Vehicle Type: Typically, compact cars have a fuel tank capacity of 35-45 liters, while mid-sized cars have a fuel tank capacity of around 55-75 liters. A full tank usually allows for a range of about 500 kilometers, depending on the car's displacement. Cars with higher fuel consumption tend to have larger fuel tanks, and vice versa. 2. Road Conditions: The type of road driven on is also crucial. National highways often have heavy traffic and poor road conditions, leading to slower speeds and higher fuel consumption. On highways, maintaining a consistent speed over long distances allows the car to perform optimally. 3. Vehicle Weight: When a vehicle is moving at a completely constant speed, the impact of weight on fuel consumption is minimal. However, even a slight increase in weight can significantly raise the rolling resistance and friction between the tires and the road surface. For average family cars, an increase of 100 kilograms in weight results in a fuel consumption change of less than 2%. Under optimal road conditions, with a tailwind and reasonable load, it's not uncommon to observe an increase in range by more than 50%.
