Oshan Kosai uses Changan's engine. Oshan Kosai is an independent brand, but it uses Changan's engine. More details about the Oshan Kosai are as follows: 1. The 1.5-liter turbocharged engine equipped in the Kosai is the same as the 1.5-liter turbocharged engine in the Changan CS75, but there are some differences in tuning and power parameters. When the same engine is used in different cars, automakers generally give it different tuning. 2. The power output method of a turbocharged engine is different from that of a naturally aspirated engine. A naturally aspirated engine can only output greater torque in the mid-to-high RPM range. A turbocharged engine can output maximum torque at very low RPM ranges, so the initial power of this engine is very strong, and turbocharged engines are also more suitable for driving on stop-and-go urban roads. 3. However, turbocharged engines may lack power reserves in the high RPM range at the later stage and may also experience the phenomenon of 'dry roar without moving.' Although large-displacement naturally aspirated engines have weaker power at low RPMs, they can provide continuous power in the mid-to-high RPM ranges.

I've been driving my Oshan Kosai for a few months now. The engine is Chang'an's own brand, featuring a 1.5T turbocharger. It's quite powerful with ample performance and good fuel efficiency. Whether cruising around the city or overtaking on the highway, it handles effortlessly. Chang'an has done a great job with their engines—I've heard they've incorporated some foreign technology, making them durable with few minor issues. For new drivers considering this car, I think it's a solid choice with high cost-performance and affordable maintenance costs. Personally, I appreciate its reliability—the engine starts smoothly with a steady sound, and long drives don't feel tiring. The overall driving experience is excellent, and I highly recommend it to budget-conscious friends looking for an SUV. For maintenance, regular oil changes and avoiding unnecessary modifications can help extend the engine's lifespan.

Should You Use Internal or External Air Circulation When Running the Car AC in Summer?

Choosing between internal and external air circulation when running the car AC depends on specific circumstances. Here are the key considerations: External Circulation Mode: This mode uses the fan to draw outside air into the car, meaning the air passage between the exterior and interior remains open. The air blown by the fan comes from outside, and even with the fan off, airflow is still drawn into the car while driving, replenishing fresh air inside. Sometimes, you may feel airflow even when the fan is off—this occurs because external circulation is enabled. In urban traffic jams, the car may fill with exhaust fumes due to external circulation drawing in surrounding vehicle emissions. Internal Circulation Mode: This mode closes the airflow passage between the inside and outside of the car. Without the fan, there is no airflow circulation, and when the fan is on, the airflow is drawn solely from inside the car, creating an internal air loop. Internal circulation primarily blocks external dust and harmful gases from entering, such as when driving through smoke, dust, areas with strong odors, or dense traffic, preventing harmful exhaust from preceding vehicles. Another benefit is maintaining cabin temperature.

How often does a new car need an annual inspection?

New cars are exempt from inspection for the first 6 years. Below are the relevant regulations for vehicle annual inspections: Elimination of environmental protection label: China's traffic authorities have issued new regulations stating that as long as the vehicle passes the annual inspection, the environmental protection label no longer needs to be displayed. Elimination of compulsory insurance label: Currently being piloted in Beijing, vehicles in Beijing can stop displaying the compulsory insurance label and switch to electronic policies. Inspection exemption period: Non-commercial vehicles such as passenger cars are exempt from inspection for 6 years, but every 2 years, the owner must submit the compulsory insurance policy and vehicle and vessel tax certificate to the vehicle management office, then directly apply for the inspection compliance label from the traffic police department.

What does max mean?

MAX on a car refers to the maximum value. Below are the meanings of MAX in different locations: Car air conditioning: If it's in the car air conditioning system, MAX indicates the upper limit of the cooling mode. Engine oil dipstick: If it's on the engine oil dipstick, MAX represents the upper limit of the fluid level. When adding engine oil, make sure the fluid level does not exceed the MAX mark. Car fluid reservoirs: MAX on car fluid reservoirs indicates the upper limit of the fluid level in each reservoir. The fluid level should not exceed the horizontal line corresponding to MAX, and it should be between the upper and lower limits. Additional information: Vehicles all have MAX markings, but they are distributed in different locations. Some are on the fluid containers in the engine compartment, while others are on the car interior. In daily use, pay attention to the MAX mark when adding windshield washer fluid or power steering fluid. Reaching this mark indicates that the addition is complete.

Why is there no air coming out from the windshield defroster vent?

The angle adjustment button for the air vents on the vehicle's air conditioning control panel is malfunctioning, preventing the air flow from being redirected; the pipelines of the vehicle's heating system are clogged and need to be cleaned at an auto detailing or car wash shop. Below is relevant information: Air vent adjustment: There are five adjustment modes. The first is the foot mode, the second is the foot and face mode. The third is the face mode. The fourth is the windshield and foot mode. The fifth is the independent air flow mode, which can be switched via buttons or knobs according to different usage environments. Notes: The air conditioning system must have the vehicle's AC switch turned on for operation, whereas the heating system does not require this. When using the air conditioning, the vehicle's internal circulation should be activated, switching to external circulation every half hour. For the heating system, external circulation can be used without the need for frequent switching to internal circulation.
