Why does an automatic transmission have high RPM but no acceleration?

Automatic transmission has high RPM but no acceleration due to the following reasons: Transmission slipping: When the vehicle experiences high RPM but no acceleration and delayed gear shifting, it is mostly caused by automatic transmission failure. Common issues like transmission slipping can lead to this situation. Transmission oil leakage: Low or high oil levels, as well as transmission oil leakage, can easily cause the oil pump to suck in air, resulting in poor lubrication and incomplete operation, which leads to slipping. Poor transmission oil quality: Check the quality of the transmission oil. If it appears dark brown or has a burnt smell, it indicates the transmission oil is severely contaminated. In extreme cases, it can even clog the oil passages, causing abnormal operation of the transmission valve body.

What is the fuel tank capacity of the Great Wall Fengjun 5?

Great Wall Fengjun 5 has a fuel tank capacity of 70 liters, which is the officially announced data. Owners who have purchased the Great Wall Fengjun 5 can also check this information on the vehicle's configuration sheet. The fuel grade for the Great Wall Fengjun 5 is 92, with a fuel consumption of 8.7L per 100 kilometers. A full tank can cover a distance of approximately 805km. During daily driving, it is necessary to always pay attention to the remaining fuel in the tank. Generally, the fuel level is observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the manufacturer is from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion when the temperature rises, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated fuel tank capacity.

Can I still drive with a tire pressure of 168?

Tire pressure of 168 is not recommended for continued driving. Since a reading of 168 is significantly below the normal range, you should promptly find a safe place to stop the vehicle and inflate the tires to around 250. Normal tire pressure range: The manufacturer's recommended tire pressure is generally between 2.2-2.5. This recommended value can usually be found in the vehicle's user manual or near the door (B-pillar or C-pillar). Hazards of low tire pressure: The most serious consequence of low tire pressure is a blowout. Similarly, excessively high tire pressure can also cause a blowout. However, low tire pressure is often difficult to detect unless intentionally checked. Driving for extended periods with low tire pressure can cause significant damage to the tires and, in severe cases, endanger the safety of the driver and passengers.

What Happens When the Injection Nozzle Pressure of a Diesel Vehicle is Insufficient?

Insufficient injection nozzle pressure in a diesel vehicle can cause the internal needle valve to fail to close tightly. Here are additional details: 1. Causes of low injection pressure: Excessive clearance between the needle valve guide and the needle valve body or poor sealing of the needle valve cone surface; poor sealing between the injection nozzle and the injector body contact surface; loose adjusting screw; insufficient or broken pressure regulating spring. If the injection pressure is too high or too low, the injector should be disassembled, cleaned, and undergo corresponding adjustments and repairs. 2. Hazards of low injection pressure: If the pressure is set too low, the atomization quality of the fuel will significantly decrease, diesel consumption will increase, and the diesel engine will be difficult to start. Even if it starts, incomplete combustion in the diesel engine will cause continuous black smoke from the exhaust pipe, and carbon deposits will easily form on the injection nozzle needle valve. If the injection pressure is set too high, it can cause knocking sounds during diesel engine operation, reduce power output, accelerate wear on the injection pump plunger assembly and injector, and sometimes even rupture the high-pressure pipe.

How Far Can You Drive on the Last Fuel Gauge Bar?

When the fuel gauge shows only one bar left, the car can typically travel approximately 40-60 kilometers, though the exact distance depends on the vehicle model and other factors. Driving with one bar of fuel left does not harm the car: When only one bar of fuel remains, the yellow fuel warning light illuminates as a cautionary signal, primarily to alert the driver that it's time to refuel. While low fuel levels could potentially damage the fuel pump, having one bar left still ensures the fuel pump remains adequately cooled, preventing any harm to the vehicle. Refueling recommendation: It is advisable to refuel as soon as the yellow warning light comes on, rather than waiting until the fuel gauge turns red. A red fuel light indicates that the fuel level has dropped below the fuel pump, which can cause damage. Therefore, even though the car can still operate with the yellow light on, it's best to head to a gas station promptly for refueling.

What causes difficulty in shifting gears for Dongfeng Tianlong?

The reasons for difficulty in shifting gears in Dongfeng Tianlong are as follows: 1. The positioning component of the gearshift lever's ball head fails: The gearshift lever can rotate freely around its own axis, making it impossible to accurately control the gear position; it may also be due to wear on the spherical working surface at the lower end of the gearshift lever, preventing it from controlling the shift fork or the shift head's groove, making both engaging and disengaging gears impossible. If it's the first case, the issue can be resolved through repair; if it's the second case, the gearshift lever needs to be replaced directly. 2. The clutch fails to disengage completely while the transmission's shifting mechanism is operational. This fault can be resolved by adjusting the clutch or replacing some clutch components to ensure the clutch has appropriate free play and separation clearance. 3. Pressure plate failure: This may also cause difficulty in engaging gears. The issue of hard shifting when the engine is hot is mostly caused by long-term wear of the pressure plate or aging of the separation fingers, requiring replacement of the pressure plate. This repair is relatively complex, as the entire transmission must be removed to replace the pressure plate. 4. Issues with the gear selection or shift cables: Manual transmission cars still use two cables for gear shifting during operation. If either of these cables breaks, it can lead to gear shifting problems. 5. Poorly run-in components: If the components inside the transmission of a new car have not been properly run-in, some gear components may be stiff, causing difficulty in shifting. This situation will naturally improve after a period of running-in. 6. Transmission oil issues: If the transmission components lack oil or the oil quality is poor, shifting will feel stiff. Transmission oil is similar to engine oil and requires regular checks and timely top-ups.
