What is the actual fuel consumption of the Roewe RX5?

There are a total of 10 Roewe RX5 models currently on sale. Among them, 7 models from the years 2021-2022 are equipped with a 181-horsepower engine, with an NEDC fuel consumption of 6.9L per 100 kilometers. The 3 models from 2020 are equipped with a 169-horsepower engine, with an NEDC fuel consumption of 6.8L per 100 kilometers. The fuel tank capacity of the Roewe RX5 is 55L. The distance that can be covered with a full tank of fuel is as follows: For models equipped with the 181-horsepower engine, the distance with a full tank is 55/6.9*100=797km. For models equipped with the 169-horsepower engine, the distance with a full tank is 55/6.8*100=809km. 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 in advance when approaching 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 tend to have higher fuel consumption 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, leading to higher fuel consumption. Environmental temperature: Low temperatures cause the engine block to be cold, making it harder for the injected gasoline to atomize during cold starts. More gasoline needs to be injected to achieve combustion, increasing fuel consumption. Additionally, in cold weather, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Why Can't Refrigerant Be Added to the Car Air Conditioner?

If the low-pressure side is high and the high-pressure side is low, it may indicate that the compressor is damaged. In such cases, refrigerant cannot be added. The most common symptom of a dirty or clogged expansion valve is frosting. Below is an introduction to car air conditioning: 1. Introduction to Car Air Conditioning: The car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the vehicle, providing a comfortable environment for the driver. 2. Working Principle: When the compressor operates, it sucks in low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy and turn into a liquid.

What's the difference between 1.4t and 2.0t?

1.4t and 2.0t differ in displacement: 1.4t represents a 1.4-liter displacement, while 2.0t represents a 2.0-liter displacement. The 't' stands for turbocharging. The main function of turbocharging is to increase the engine's air intake through a turbocharger, thereby enhancing the engine's output power and torque. A turbocharger is essentially an air compressor that boosts intake air volume by compressing air. It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber, which in turn drives a coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipe, forcing it into the cylinders under increased pressure.

Do Pickup Trucks Have a Scrap Period?

Because pickup trucks belong to the category of light-duty trucks, they have a scrap period. The scrap period for pickup trucks is 10 years, with a mandatory scrap period of 15 years. The vehicle scrap period refers to the safety inspection system based on the number of seats and usage time during the vehicle's service life, generally applicable only to commercial vehicles. This system was issued on January 14, 2013, and officially implemented on May 1, 2013. Regarding the scrap period for pickup trucks: Currently, pickup trucks are still subject to the mandatory scrap regulation of 15 years or 600,000 kilometers. Some regions have gradually relaxed the 15-year scrap rule for pickups, and household pickup trucks do not have a scrap period. However, they are subject to the 600,000-kilometer scrap regulation. According to the pickup truck inspection rules: new pickups are exempt from inspection for the first 6 years, but within the first 6 years, they must be stamped at the vehicle management office every two years. From 7 to 15 years, they must be inspected annually, and after 15 years, they must be inspected every six months. Pickups that fail the inspection or exceed 600,000 kilometers must be scrapped. Regarding the scrap time for motor vehicles: 1. Non-commercial passenger vehicles with 9 seats or fewer have a scrap period of 15 years, and those with more than 9 seats have a scrap period of 10 years, with a mandatory scrap period of 20 years. 2. Tourist buses have a scrap period of 10 years, with a mandatory scrap period of 20 years. 3. Commercial passenger vehicles have a scrap period of 10 years, with a mandatory scrap period of 15 years. 4. Light-duty trucks have a scrap period of 10 years, with a mandatory scrap period of 15 years. 5. Passenger vehicles with more than 20 seats have a scrap period of 8 years, with a mandatory scrap period of 12 years. 6. Passenger vehicles with fewer than 19 seats and mini trucks have a scrap period of 8 years.
