What Causes Excessive Exhaust Gas in Diesel Engines?

What brand is the JAC J7?

JAC J7 is a compact sedan under the JAC brand. Here is more information about the JAC J7: 1. The JAC J7 is equipped with a 1.5-liter turbocharged engine across all models. This engine delivers 150 horsepower and a maximum torque of 210 Nm, reaching its peak power at 5,500 rpm and maximum torque between 2,000 and 4,500 rpm. The engine features i-VVT technology and multi-point fuel injection, with an aluminum alloy cylinder head and block. 2. The engine is paired with either a 6-speed manual transmission or a CVT. The CVT offers smooth shifting, good reliability, and durability. Its simple structure, lightweight, and compact size contribute to better fuel efficiency in vehicles equipped with it. 3. The JAC J7 uses a MacPherson independent suspension at the front and an E-type multi-link independent suspension at the rear. The multi-link independent suspension enhances wheel contact with the road, improving traction and, consequently, the vehicle's handling performance.

Where is the air filter of Changan CX20 located?

The air filter of Changan CX20 is located inside the glove compartment on the passenger side. Open the glove compartment, push inward firmly on both sides to remove it, and you will see a black cover. Use a Phillips screwdriver to remove the small cross-head screw. After removing the cover, you can see the air filter. The functions of the air filter are as follows: 1. Filter dust particles in the air to prevent these pollutants from entering the car's evaporator and causing sludge that may block it. If the airflow from the vents noticeably weakens, it may be due to blockage. 2. The air filter also filters dust, mist, pollen, carbon oxides, and sulfides in the air. Since the filter contains activated carbon, it can absorb harmful gases and particles in the air.

What Happens If a Car Isn't Serviced for a Year?

If a car isn't serviced for a year, it can lead to abnormal wear and tear on the vehicle and engine, increasing the likelihood of vehicle malfunctions, accelerating engine wear, and raising maintenance costs. The hazards caused by prolonged vehicle inactivity are as follows: 1. Paint is prone to oxidation and aging: If the car is parked in an open-air parking lot, prolonged exposure to strong sunlight can cause the paint to fade, oxidize, and even crack. Automotive paint contains large amounts of resins, metals, and other substances that make it susceptible to oxidation. Especially under harsh environmental influences such as UV rays, acid rain, bird droppings, and dust, the paint is more likely to oxidize and age. Additionally, it's important to prevent scratches from other objects or vehicles, as well as intentional vandalism. 2. Severe engine wear: It's commonly believed that only frequently used engines suffer damage, but automotive experts reveal that prolonged inactivity can cause the lubricating oil film on the engine cylinders and piston surfaces to deteriorate due to exposure to oxygen and corrosive acids and alkalis in the air. This deterioration forms a gummy substance, losing its lubricating properties. The longer the vehicle remains inactive, the worse the deterioration becomes. When the engine is restarted, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear. Moreover, starting resistance increases significantly, making it difficult to start, and prolonged inactivity can completely ruin the engine. 3. Tire deformation: Unlike bicycles, cars are made of heavy materials like steel, making them quite heavy. When a car is parked, its weight is supported by the four tires' contact points with the ground, causing localized compression and deformation. The longer the car remains inactive, the harder it is for the deformed areas to recover, altering the tire's weight distribution and creating uneven rolling radii, leading to imbalance. Once the car reaches high speeds, it can cause body vibrations, affecting ride comfort, accelerating tire wear, and introducing safety risks.

What to Do When There's a Sour Smell from the Car Air Conditioner?

Car air conditioners emitting a sour smell may be due to unclean air filters, dirty air ducts, or accumulated dust on a damp evaporator. Relevant explanations are as follows: 1. A large amount of impurities and dust can generate various molds harmful to human health. Besides timely cleaning of the evaporator (the air conditioning system is generally cleaned once a year, preferably before summer), it is also recommended to replace the air filter and clean the air conditioning system. 2. Skillful use of the air conditioner can effectively keep the evaporator dry, reducing the breeding of bacteria and mold. Timely replacement of the air filter is also a very effective method. Extended content: The function of a car air filter is to filter the air entering the car interior from the outside, improving air cleanliness. Common filtering substances include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust.

What Are the Consequences of Not Maintaining a Car?

The consequences of not maintaining a car include warranty voidance, paint corrosion, engine wear, oil degradation, filter clogging, tire aging, wiper hardening, wiring faults, and more. More detailed information is as follows: 1. From an external perspective, the car's paint is particularly vulnerable to damage, especially during the hot summer months when UV rays can corrode the paint. This can cause the car to lose its shine and appear aged. In more severe cases, the car's body may develop cracks. 2. If the air filter is not replaced in time, it can accumulate a lot of dirt, clogging the engine and causing ignition issues. Similarly, not replacing spark plugs after prolonged use can lead to ignition difficulties and even increased fuel consumption. 3. Tires will age, and if debris on them is not cleaned off, it can wear down the tires over time, potentially leading to blowouts.
