What engine does the Changan Oshan Kosai have?

Is the heat insulation film applied inside or outside the car?

Inside the car. The functions of automotive heat insulation film are as follows: 1. Thermal insulation: Blocks infrared radiation and absorbs a small amount of heat conduction, achieving relative insulation and indirectly reducing air conditioning load for energy saving. 2. UV blocking: Most mid-to-high-end heat insulation films on the market can block over 98% of UV rays, protecting the skin of drivers and passengers from UV damage, and more importantly, delaying premature fading, aging, and cracking of car interior items and leather. 3. Explosion-proof: High-quality automotive heat insulation films use special materials for the adhesive and plastic substrate, providing excellent adhesion and impact resistance, significantly improving safety by preventing theft, robbery, and collisions.

What are the precautions for inspecting a new car upon delivery?

Precautions for inspecting a new car upon delivery are: 1. First, visually inspect the body paint for scratches and wear. Observe the paint under ample sunlight to check for color differences, and open the doors to push and pull them at various angles to let light shine from different directions to check if the sheet metal is even; 2. Open the doors and pay attention to whether they open and close smoothly, and whether the gaps between the doors and the front and rear bumpers are consistent; 3. Open the engine hood to check if the engine compartment is clean. If the car has been stored for a long time or used, some areas may have obvious dust or stains; 4. Check if the windshield is original; 5. Inspect the vehicle's nameplate, which is located on the side of the driver's door or in the engine compartment. Pay attention to whether the manufacturing date is too far from the current date. If it exceeds six months, the car is likely to be an inventory or test-drive vehicle.

Can You Still Drive with a Faulty High-Pressure Fuel Pump?

You can still continue driving. Early symptoms of a faulty high-pressure fuel pump may include weak acceleration, jerking during sudden acceleration, difficulty starting, illuminated engine warning light, and unstable idle. When the high-pressure fuel pump fails, simply replace it with a new one. It is recommended to use genuine parts and have the replacement done at an authorized 4S shop. Below is an introduction to the high-pressure fuel pump: 1. Main materials used: The high-temperature and high-pressure all-carbon-steel gear-type residual oil pump primarily uses Q235 ordinary carbon steel for its three main components. Gears, thrust plates, and other parts are made of alloy structural steel and undergo special heat treatment to significantly enhance hardness and wear resistance. 2. Unique performance: The high-temperature and high-pressure all-carbon-steel gear-type residual oil pump employs proprietary hydraulic balancing technology, delivering high efficiency, low noise, stable pressure, and extended pressure-holding time under high-temperature and high-pressure conditions.

What faults will occur if the high-pressure fuel pump loses pressure?

If the high-pressure fuel pump loses pressure, the engine may be difficult to start and may stall during startup. More details are as follows: 1. Pressure relief valve explanation: The pressure relief valve, also known as the overflow valve or safety valve, opens when the fuel supply line pressure exceeds the limit, directly releasing the pressure into the fuel tank. For example, the general limit is 450kpa. Possible causes include blockage or bending of the fuel supply line, bending or blockage of the return line, or a clogged fuel filter. 2. Inspection method: First, determine whether it is a fixed displacement pump or a variable displacement pump. For a fixed displacement pump, check the pump's maximum pressure. If it meets the standard, try replacing the overflow valve. If there is still no change, check whether the pump is severely worn or has excessive internal leakage. For a variable displacement pump, first check the pump's pressure setting, and then follow the same steps as for a fixed displacement pump.

Can High RPM Clean Carbon Deposits?

No. The causes of carbon deposits are explained as follows: 1. Formation of carbon deposits: Carbon deposits are residues produced after the mixed combustion of fuel and lubricating substances. These materials cannot be consumed by flames during the combustion process, hence the remaining substances; their main components are: hydroxy acids, asphaltenes, tar, etc. This is mainly due to incomplete combustion of the fuel-air mixture and poor combustion efficiency during the combustion process, leading to significant material precipitation. 2. Prolonged idling: If the engine idles for a long time or frequently stops and starts, the time it takes for the engine to reach normal operating temperature increases. This causes gasoline sprayed behind the intake valves to atomize more slowly, and the air flow entering the engine also becomes relatively smaller. Under these driving conditions, the "scouring effect" on valve carbon deposits weakens, promoting the deposition of carbon. 3. Evolution of lubricating substances: Since all engine components require lubrication, besides the engine oil itself, even the lubricating substances contained in the fuel can contribute to carbon deposit formation during combustion.

How Many Years Can Heat Insulation Film Last?

Automotive heat insulation film typically lasts for about 5 years. The lifespan of the heat insulation film is directly related to the quality of the film material, the quality of installation, the vehicle's usage environment, and subsequent maintenance. It is important not to attach suction cups, labels, or similar items directly onto the film's surface. If you need to affix an annual inspection sticker, an electrostatic sticker can be used. The functions of automotive heat insulation film are as follows: 1. Heat Insulation: It blocks infrared radiation and absorbs a small amount of conductive heat, achieving relative heat insulation and indirectly reducing air conditioning load, thereby saving energy. 2. UV Protection: Most mid-to-high-end heat insulation films available on the market can block over 98% of ultraviolet rays, protecting the skin of drivers and passengers from UV damage. More importantly, it delays the premature fading, aging, and cracking of car interior items and leather. 3. Explosion-proof: High-quality automotive heat insulation films use special materials for the adhesive and plastic substrate, providing excellent adhesion and impact resistance. This significantly enhances the vehicle's safety by preventing theft, robbery, and collision hazards.
