Where is the Roewe RX5 MAX engine produced?

Roewe RX5 MAX engine is produced by SAIC Motor Corporation Limited, so this engine is domestically made. Roewe RX5 MAX uses two types of engines, with model numbers 20L4E and 15C4E. The 20L4E engine has a maximum horsepower of 231 HP, maximum power of 170 kW, maximum power speed of 5300 rpm, and peak torque of 370 N·m. The 15C4E engine has a maximum horsepower of 181 HP, maximum power of 133 kW, maximum power speed of 5600 rpm, and peak torque of 285 N·m. For daily maintenance of the Roewe RX5 MAX engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB_CD grade diesel engine oil should be selected based on 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, performance deteriorates, leading to 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 holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. 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. Small amounts remain suspended in the oil, while large amounts precipitate, 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 normal engine operation but also extends the overall lifespan of the radiator and engine.

How to Determine When to Clean the Throttle Body?

Determining when to clean the throttle body involves observing unstable vehicle acceleration and idle speed. The steps for cleaning the throttle body are: 1. Remove the air filter and intake pipe, unplug the throttle body socket, and take out the throttle body; 2. Spray cleaning agent and wipe the throttle body with a tissue. Precautions for cleaning the throttle body include: 1. It should be disassembled for cleaning; 2. Correct misconceptions about throttle body cleaning; 3. Develop proper driving habits and regular maintenance, avoiding the use of low-quality gasoline. The throttle body is connected to the air filter at the top and the engine block at the bottom, and it is divided into: traditional cable-type and electronic throttle bodies. The working principle of the throttle body is to control the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which burns to generate power.

What is the correct way to install a license plate?

The correct way to install a license plate is: 1. Prepare the screw components and screw all the fixing screw components according to the fixing points of the license plate; 2. Align the license plate with the car's fixing points, straighten and align it, insert the screws into the holes, but do not tighten them; 3. Check that the license plate is in the correct position and tighten all the screws; 4. Press the cap onto the spacer to fix it, and the installation is complete. License plates, commonly known as tags, also refer to vehicle license plates, which are plates hung on the front and rear of the vehicle. They are usually made of aluminum, iron, plastic, or paper, and are engraved with the vehicle's registration number, registration area, or other relevant information.

How to reset the tire pressure warning light on the car?

The method to reset the tire pressure warning light on the car is: Press and hold the SET button with the tire pressure symbol located at the front of the gear lever. The reasons for the tire pressure warning light appearing on the car are: 1. Tire leakage; 2. Tire pressure too high or too low; 3. System false alarm. Common warning lights on the car include: 1. Engine fault warning light; 2. Low oil or low oil pressure warning light; 3. ABS system fault light; 4. Brake system fault light; 5. Seat belt indicator light; 6. Low fuel warning light; 7. Battery and charging system fault light; 8. Trunk lid open and engine hood open warning lights.

What is car gear dragging?

Car gear dragging occurs due to: 1. Aging of the gear shifting mechanism; 2. Aging of the synchronizer; 3. Poor driving habits that cause long-term damage to the vehicle. The symptoms of car gear dragging include: 1. The engine sound becomes muffled; 2. Slow response and lack of speed when accelerating; 3. The car jerks forward and backward when releasing the accelerator. Car gear dragging refers to the mismatch between the gear position and the actual driving conditions, which can be divided into: 1. Low gear high drag: Forces the engine to operate at excessively high RPM, putting undue pressure on engine components; 2. High gear low drag: The engine RPM is too low, resulting in weak power output and a tendency to stall.

What is the difference between water and antifreeze?

The differences between water and antifreeze are: 1. Different freezing points: The freezing point of water is 32 degrees; the freezing point of antifreeze is -40 degrees. 2. Different boiling points: The boiling point of water is 100 degrees Celsius; the boiling point of antifreeze is 108 degrees Celsius. 3. Different functions: Water can cause rust in the engine's water passages and lead to scale buildup; antifreeze prevents the coolant from freezing and cracking the radiator when parking in cold winter. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems, with excellent properties such as preventing freezing in winter, preventing boiling in summer, and preventing scale and corrosion all year round. The boiling point of water is 100 degrees Celsius. When the temperature reaches 100 degrees Celsius, water evaporates into steam and cannot serve as a coolant.
