What is the engine of the Weizhi V5?

2 Answers

The engine of the Weizhi V5 is independently developed by the FAW Group Technology Center and is a domestically produced engine. The engine model of the Weizhi V5 is CA4GA5, with a maximum power of 75 kW, a maximum torque of 135 Nm, and a maximum horsepower of 102. For daily maintenance of the Weizhi V5 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 specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When engine oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and the oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing the filter and carrying 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. In small amounts, it remains suspended in the oil; in large amounts, it precipitates out, 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 the engine operates normally but also extends the overall lifespan of the radiator and engine.

I've been commuting with a Weizhi V5 for almost three years now, equipped with Toyota's 1.5-liter VVT-i gasoline engine, and its overall performance has been quite reliable. Driving in the city, the power delivery is smooth, and a full tank can easily cover over 500 kilometers. The fuel consumption is around 6-7 liters per 100 kilometers, and daily maintenance is hassle-free—just regular oil and filter changes to avoid common minor issues. I recommend cleaning the throttle body periodically to prevent carbon buildup from affecting efficiency. The engine noise is minimal, making long trips comfortable without fatigue. Overall, this engine prioritizes practicality, offers high reliability, and is trustworthy. Remember to use the right engine oil to extend its lifespan.

Where to Add Car Antifreeze?

The antifreeze should be added to the car's radiator, which can be located by opening the engine hood. The full name of car antifreeze should be anti-freeze coolant, meaning it is a coolant with anti-freezing properties. Car antifreeze prevents the coolant from freezing and expanding in cold weather, which could damage the radiator and crack the engine cylinder liners. Antifreeze is not just for winter use—during regular vehicle maintenance, the engine antifreeze should be replaced, with higher replacement frequency for special-purpose vehicles. Functions of Antifreeze: Anti-Freeze Function: This is the most basic function of car antifreeze. The freezing point of antifreeze is relatively low, and using it in winter prevents the cooling system from freezing. Proper use of antifreeze ensures the car operates normally even in cold weather, which is the primary reason many car owners add antifreeze. Cooling Function: Car antifreeze is also known as coolant. When the car engine is running, it generates a large amount of heat, most of which needs to be dissipated through the cooling system. Due to its material composition, antifreeze has a relatively low boiling point, making it effective for cooling and heat dissipation. Anti-Corrosion Function: The car's cooling system is made of metal, which is prone to electrochemical corrosion over time. Severe corrosion can paralyze the cooling system. Antifreeze usually contains corrosion inhibitors to effectively prevent corrosion in the cooling system. Anti-Scale Function: Scale can easily form in the cooling system, adhering to the outer surface of the cylinder and significantly reducing thermal conductivity, thereby diminishing cooling efficiency. Antifreeze typically contains deionized water to prevent scale buildup. Precautions: Different types of antifreeze should not be mixed, as this may cause chemical reactions, sedimentation, or bubbles, reducing effectiveness. When replacing antifreeze, flush the cooling system with clean water before adding new antifreeze and water. Label any remaining antifreeze to avoid confusion. Since different antifreeze formulations have varying freezing points due to their composition and ratios, choose one based on local temperature conditions. The antifreeze's freezing point should generally be 10°C to 15°C lower than the local minimum temperature to prevent failure. If the antifreeze level drops due to a leak in the cooling system, add the same type of antifreeze. If the drop is due to evaporation, add distilled or soft water to the cooling system. If suspended particles, sediment, or odor are detected, replace the antifreeze entirely and clean the cooling system. Ethanol-based antifreeze is volatile, so take precautions against fire. If the engine overheats, do not open the radiator cap or shut off the engine immediately, as rapid temperature changes may cause antifreeze to spray, leading to injury or fire. If the ethanol level drops due to evaporation, replenish with 80% ethanol. Ethylene glycol is an organic solvent—avoid spilling it on rubber parts or painted surfaces, and take care not to let it contact the skin. If spilled, rinse immediately with water to prevent corrosion or skin damage. Antifreeze should be used year-round. Some drivers use antifreeze only in winter and switch to plain water in spring, only replacing it again in winter. This can lead to corrosion and damage in the cooling system, potentially causing the engine to overheat or even crack the cylinder head, significantly shortening the car's lifespan. For vehicles with high mileage, such as taxis, high-quality antifreeze should be replaced annually, while those with low mileage can replace it every two years.

What to Do When Experiencing Jerking During Low-Speed Braking or Acceleration?

Jerking during low-speed braking or acceleration is typically caused by faults such as a malfunctioning torque converter in the transmission, a faulty transmission oil pump, clogged oil passages, or excessively high or low transmission oil pressure. It is essential to promptly inspect and repair the issue, including cleaning the oil passages, fuel injectors, oil lines, and pipes. For automatic transmission vehicles, some jerking during initial acceleration is normal. If you need to accelerate quickly while driving, you should press the accelerator pedal firmly. In this case, the automatic transmission will downshift to increase the engine speed. Once the speed reaches a certain level, the transmission will upshift. After upshifting, the engine speed will drop noticeably, resulting in a relatively pronounced jerking sensation.

Is it illegal to convert a manual transmission to an automatic transmission?

From a legal perspective, converting a manual transmission to an automatic transmission is not illegal, but modifications should be done with caution as they may affect the annual inspection. A manual transmission can be converted to a pseudo-automatic transmission: By installing an electronic control system that assists the driver in operating the clutch, but gear shifting still requires manual operation. When shifting gears, the system controls a motor to automatically depress the clutch, and releases it after the gear is engaged, preventing stalling. The system also provides prompts when shifting is needed. Disadvantages of modification: After modification, the vehicle may fail the annual inspection. Unauthorized modifications can also affect insurance claims, as accidents caused by modified parts will not be covered.

How Long Can National V Standard Vehicles Be Driven After the Implementation of National VI Standard?

After the promulgation of the National VI standard, there is no impact on National V standard vehicles, and National V standard vehicles can be driven with confidence. The National VI standard is different. After the implementation of the National VI standard, National IV and National V vehicles can still be driven without significant impact in the short term. However, National III vehicles will be affected after the implementation of the National VI standard. As long as regular vehicle maintenance is performed, good driving habits are maintained, and all exhaust emission indicators meet the standards, National V vehicles can be driven on the road. Compared with National V, the National VI standard reduces nitrogen oxides by 77%, particulate matter by 67%, introduces limits on the number of particles, and tightens the durability requirements of emission control devices and the relevant requirements of on-board diagnostic systems.

Where is the air conditioning filter located on the Chery Fengyun 2?

Chery Fengyun 2 air conditioning filter is located at the upper left of the engine compartment, which is under the right wiper. The air conditioning filter sealing cover is fixed by two screws. Remove the two screws and lift the sealing cover to see the air conditioning filter, and then you can remove it. When the car is driving with the air conditioning on, it needs to draw in external air into the cabin. The air contains many different particles, such as dust, pollen, soot, grinding particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. Without the air conditioning filter, once these particles enter the cabin, not only will the car's air conditioning be polluted and the cooling system performance reduced, but also the human body will have allergic reactions and lung damage due to inhaling dust and harmful gases, be irritated by ozone, and be affected by odors, all of which affect driving safety.
