What engine is equipped in the Ruifeng M3?

The engine of the Ruifeng M3 is independently developed by JAC Motors, so it belongs to a domestic engine. The Ruifeng M3-1.5T turbocharged engine model is HFC4GB2-4E, with a maximum horsepower of 150, a maximum power of 110KW, a maximum power speed of 5500rpm, and a maximum torque of 210N.m. The 1.8L naturally aspirated engine model is LJ4A18Q6, with a maximum horsepower of 133, a maximum power of 98KW, a maximum power speed of 5600rpm, and a maximum torque of 182N.m. The engine of the Ruifeng M3 can be maintained daily using the following methods: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, causing various problems for the engine. To avoid faults, the oil should be changed regularly according to usage conditions, and the oil quantity should be moderate; When the 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 blocked and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to pass through the bypass valve and bringing dirt back to the lubrication area, accelerating engine wear and internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, water, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. A small amount of sludge suspends in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall life of the radiator and engine.

What Causes White Smoke from Engine Exhaust?

White smoke from engine exhaust is caused by the engine burning coolant. The reason the engine burns coolant is due to cracks in the cylinder block. When this occurs, the cylinder block and cylinder head gasket should be inspected. If cracks are found in the cylinder block or cylinder head gasket, they should be replaced promptly. An engine is a machine that converts other forms of energy into mechanical energy. It was invented in England and can refer to both the power-generating device and the entire machine including the power unit (such as gasoline engines, aircraft engines). Engine types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), and electric motors.

What is the Difference Between Synthetic Oil and Mineral Oil?

Synthetic oil and mineral oil differ in the following ways: 1. Manufacturing Process: Synthetic oil is fully synthesized, while mineral oil is based on refined petroleum with added additives; 2. Cost: Synthetic oil has a more complex production process and higher costs, whereas mineral oil is more affordable; 3. Performance: Synthetic oil offers superior high and low-temperature performance, while mineral oil is a more basic type with relatively poorer performance. Engine oil consists of base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of lubricants.

How to Stop the Car Wiper?

To stop the car wiper, follow these steps: 1. The wiper switch is controlled by the wiper lever located on the lower right side of the steering wheel. It is a black lever switch. Push it upward and hold to activate the wiper, which will also spray windshield washer fluid. 2. Release the lever to stop the wiper and the washer fluid spray. 3. Moving the lever forward or backward adjusts the wiper speed, which can be selected based on the intensity of the rain. The rear wiper switch is also located on the wiper lever, but it is a separate system from the front wiper and can be controlled independently. There are two types of rear wiper switches: lever-style and knob-style.

What is a Head-Up Display (HUD)?

Head-Up Display (HUD), also known as a heads-up display, was primarily used in military fighter jets in the past as an important auxiliary instrument for aircraft. Utilizing the principle of optical reflection, it projects crucial information onto the windshield, eliminating the need for pilots to look down, thereby enhancing convenience and safety. The function of a HUD is to ensure driving stability for the driver, allowing them to focus more on observing road conditions. It projects relevant vehicle information onto the front windshield through the HUD system, enabling the driver to avoid looking down at the instrument cluster. This maximizes the driver's concentration during driving and improves road safety.

Why Is the Car Steering Wheel So Tight?

Reasons for a tight car steering wheel: 1. For hydraulic power steering, a common cause is dirty power steering fluid. Dirty power steering fluid can make the steering wheel increasingly heavy. Additionally, insufficient power steering fluid can also cause the steering wheel to feel heavier. If the issue is related to the power steering fluid, it should be promptly refilled or replaced. 2. For electric power steering, check if any fuses are blown or if there are any short circuits in the wiring. 3. For electric power steering, repeatedly turning the steering wheel while stationary or at low speeds places a significant load on the power steering system, which can easily trigger the steering gear's high-temperature protection, resulting in heavy steering. This is normal, and the steering will return to normal after cooling down.
