Is the Roewe i5 automatic transmission very fuel-consuming?

What causes water return when the engine coolant temperature is not high?

The reasons for water return when the engine coolant temperature is not high are: 1. Uneven cylinder head surface; 2. Insufficient tightening torque of cylinder head bolts or failure to compress the cylinder gasket due to extended deformation of the bolts; 3. Presence of sand holes or cavitation defects in the water passages adjacent to the combustion chamber in the cylinder block or cylinder head, causing obstruction. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by expanding the gas after combustion in a sealed cylinder, thereby pushing the piston to perform work. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning scale from the radiator; 4. Regularly removing carbon deposits from the engine; 5. Regularly replacing the three filters of the car; 6. Maintaining reasonable engine speed.

What is the ground clearance of the Outlander?

Outlander's minimum ground clearance is 19.5cm. Below is relevant knowledge about vehicle ground clearance: Advantages and disadvantages of high ground clearance: High ground clearance is suitable for mountainous roads and has relatively more advantages when facing complex road conditions compared to low ground clearance. However, precisely because of its higher ground clearance, the vehicle's overall center of gravity is also higher, making it less stable during high-speed cornering compared to vehicles with lower ground clearance. Advantages and disadvantages of low ground clearance: Its advantage lies in increasing downward pressure on the vehicle body. During high-speed driving, it can provide downward aerodynamic pressure to the body, thereby further enhancing the vehicle's grip. The disadvantage is that compared to high ground clearance, low ground clearance vehicles are more prone to scraping the undercarriage on complex road conditions such as steep slopes.

What does traffic duty mean in the driver's license test?

Before obtaining a driver's license, applicants are required to report to the traffic police department and complete 4 hours of street volunteer service. During this service, the main task is traffic guidance, including reminding pedestrians not to cross the road randomly. The purpose of this is to give trainees a firsthand experience of traffic police work and a deep understanding of the necessity of safe driving before they officially hit the road. At the same time, standing guard can effectively cultivate a sense of responsibility. The requirements for standing guard are as follows: 1. Location: The standing guard position is usually at intersections or crosswalks, with the traffic management department planning the education points, so participants only need to arrive at the designated location on time according to the assigned task. 2. Guidance: Wearing a reflective vest and holding a small red flag, participants will be instructed by traffic police to complete their duties. If any drivers or pedestrians are found violating traffic rules at the intersection, they should promptly step forward to provide guidance.

What is the actual fuel consumption of the Elysion 2.4?

Based on actual measurements, the Honda Elysion 2.4's fuel consumption shows 9.9 liters per 100 kilometers on the vehicle's computer, while the measured fuel consumption is 9.15 liters. Approximately 40% of the test route involved congested traffic. The average speed during this fuel consumption test was only 24 km/h, indicating relatively heavy traffic conditions. Under normal driving conditions, the Elysion's average fuel consumption can be kept within 10 liters. Below are additional details: 1. Elysion fuel consumption test: The vibration level during the Elysion's operation is acceptable but not particularly firm. When encountering prolonged traffic lights, the start-stop system may automatically restart the engine before the vehicle moves forward to meet performance requirements (such as keeping the air conditioning on during the test). 2. Methods to reduce fuel consumption: Improving fuel economy depends on multiple factors, including driving conditions, driving habits, vehicle condition, and load.

What is the function of the diaphragm spring in a diaphragm spring clutch?

The diaphragm spring in a diaphragm spring clutch serves the following functions: 1. It acts as both the pressure spring and the release lever, reducing the number of components and decreasing weight; 2. It shortens the axial dimension of the clutch. Below are the maintenance methods for the clutch: 1. Minimize clutch pedal usage to prevent clutch slippage and clutch disc burning; 2. Keep the contact surfaces between the release lever and the bearing cap spiral inclined plane clean and lubricated with engine oil; 3. When oil contamination or rust occurs on the friction discs, driving discs, or pressure plate inside the clutch, disassemble to remove the oil stains and clean thoroughly with gasoline; 4. Replace the friction discs if symptoms like exposed rivet heads, cracks, breakage, or large-area scorching are found. Additional information: The clutch is located within the flywheel housing between the engine and transmission, serving to disconnect or transmit the power output from the engine.

Where are the reinforcement ribs located on a car?

Most of the reinforcement ribs on a car are located on the roof, engine hood, and doors. The simplest form of a reinforcement rib is a rectangular column attached to the product's surface. However, to meet certain production or structural requirements, the shape and dimensions of the reinforcement ribs may need to be modified. Reinforcement ribs are generally found on some exterior cover panels. They enhance the strength of these panels, allowing automakers to reduce their thickness and weight, which contributes to the overall lightweighting of the vehicle. However, reinforcement ribs are typically not used on the body frame, as the passenger cell of the body frame is made from high-strength materials. Additional functions of reinforcement ribs: During assembly, seat belts can twist. To prevent this, some designs use holes and pins for positioning, while others incorporate reinforcement ribs for the same purpose. Reinforcement ribs can also be used to facilitate drainage during the painting process. By designing 2-3 reinforcement ribs with an R6 cross-section at the bottom of the inner sill panel, along with other drainage holes, the car can effectively manage fluid flow during electrophoretic painting in the paint shop, increasing the thickness of the paint film in the inner cavity.
