What does an exclamation mark in the middle of a gear mean?

An exclamation mark in the middle of a gear is a transmission fault warning light signal, corresponding to the automatic transmission control unit. It is commonly used in AMT, AT, DCT, CVT and other automatic transmissions to achieve automatic shifting control, making driving easier. When the transmission fault indicator light comes on, it indicates a problem with the transmission system, and the vehicle should be stopped and turned off immediately for repair. The transmission fault warning light may also be triggered by abnormal transmission operation, overheating, high-speed braking, or frequent gear shifting during prolonged high-speed driving, and it may turn off automatically after a while. If it does not turn off for a long time, it means there is a genuine transmission fault that requires prompt repair.

What is the horsepower of the Quanchai 4115 engine?

The Quanchai 4115 engine has 110 horsepower. Diesel engines are divided into: 1. Spark ignition engines: Diesel engines inject diesel into the intake pipe to mix with air, forming a combustible mixture that enters the cylinder and is ignited by the spark plug to expand and perform work; 2. Compression ignition engines: Diesel engines use a fuel injection pump and injector to directly inject diesel into the engine cylinder, where it mixes with compressed air and self-ignites under high temperature and pressure, pushing the piston to perform work. Horsepower is a commonly used unit for measuring power in engineering, and diesel engines are engines that burn diesel to release energy.

Where is the Oxygen Sensor Located?

Oxygen sensors are located in the exhaust pipe of the engine, demarcated by the three-way catalytic converter. The sensor before the three-way catalytic converter is the front oxygen sensor, while the one after it is the rear oxygen sensor. The front oxygen sensor detects the oxygen concentration in the engine's exhaust gases, whereas the rear oxygen sensor measures the oxygen concentration in the exhaust gases after they have been purified by the three-way catalytic converter. The oxygen sensor is a crucial feedback sensor in the electronic fuel injection engine control system, playing a key role in controlling vehicle exhaust emissions, reducing environmental pollution caused by automobiles, and improving the fuel combustion quality of the engine. There are two types of oxygen sensors: zirconia and titania.

What to Do When the Beidou Star's Water Temperature is Low?

The solution to the low water temperature in the Beidou Star is to replace the thermostat. Taking the 2020 Beidou Star as an example, its body dimensions are: length 3400mm, width 1575mm, height 1670mm, wheelbase 2335mm, front track 1360mm, and rear track 1355mm. The 2020 Beidou Star is equipped with a 1.4L naturally aspirated engine, with a maximum power of 71kW and a maximum torque of 120Nm, paired with a 5-speed manual transmission. It adopts a front suspension type of MacPherson independent suspension and a rear suspension type of non-independent single longitudinal swing arm.

How to Fold Electric Rearview Mirrors?

Method for folding electric rearview mirrors: Open the car door and locate the rearview mirror adjustment knob near the door handle. Clearly observe the gear indicators on the knob. Rotate the knob downward to the designated position for electric mirror folding. Turn the knob to "L" to adjust the left mirror angle, and to "R" for the right mirror angle. Rearview mirror folding functions come in two types: manual and electric. Manual folding requires the driver to reach outside the window or exit the vehicle to fold the mirrors, which is both inconvenient and unsafe - this type is now rare. Electric folding, being more prevalent, allows drivers to operate the mirrors from inside the car. The mirrors automatically unfold when starting the vehicle.

What are the symptoms of a faulty rear oxygen sensor?

Symptoms of a faulty rear oxygen sensor: 1. Increased engine fuel consumption and exhaust pollution; 2. The engine may experience unstable idling, misfiring, or surging. Solutions: 1. Correctly select and install rubber gaskets, and avoid applying solvents or anti-adhesive agents not specified by the manufacturer on the sensor; 2. Replace the oxygen sensor. The oxygen sensor is an essential component in engines using a three-way catalytic converter to reduce exhaust pollution. For example, the ECU determines whether the air-fuel ratio is low or high based on the electromotive force difference from the oxygen sensor and controls the fuel injection duration accordingly. If the oxygen sensor malfunctions and outputs abnormal electromotive force, the computer cannot accurately control the air-fuel ratio.

What is the main function of the suspension system?

The main function of the suspension system is to manage all forces and moments between the wheels and the vehicle body, such as supporting forces, braking forces, and driving forces. It also mitigates impact loads transmitted from uneven road surfaces to the body, dampens resulting vibrations, ensures passenger comfort, and reduces dynamic loads on cargo and the vehicle itself. The suspension system consists of shock absorbers, elastic elements, and guiding mechanisms. To control wheel travel and prevent interference between suspension components and other parts of the body or frame, bump stops are generally installed. In most passenger cars and buses, to avoid excessive lateral roll angles during cornering, anti-roll bars (or stabilizer bars) are commonly added.
