Using the HOLD function in an automatic transmission is actually quite simple. I often use it when driving on mountain roads. First, after getting on the road, drive the car to a suitable and steady speed, say 30-50 kilometers per hour, then press the button labeled 'HOLD' next to the gear shift lever. A light on the dashboard will illuminate, indicating activation. Once activated, the transmission locks in the current gear and won't shift up automatically. This is particularly useful during long descents because engine braking helps slow the car down, reducing the need to constantly press the brake pedal and minimizing brake pad wear. However, be careful not to engage HOLD at high speeds, such as on highways, as this may cause the engine RPM to rise too high, potentially damaging the transmission over time. Remember to press the button again to deactivate the mode and resume normal driving when you're done.

What causes the TC light to come on in a car?

Reasons for the TC light coming on in a car: 1. Solenoid valve failure; 2. Dirty engine oil clogging the solenoid valve filter screen; 3. Wear on the actuator gear and impeller causing oil pressure leakage and triggering the warning; 4. Dirty throttle body with opening reaching 20%, leading the engine computer to misjudge a TC fault. TC stands for Traction Control System, whose function is to enable the car to obtain optimal traction under various driving conditions. The working principle of TC involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal's information to the ECU, which then generates control voltage signals based on the received signals. The servo motor adjusts the throttle according to these signals, reducing the throttle opening and controlling tire slip. For vehicle owners driving in rainy or snowy conditions, this can help reduce occurrences of vehicle slippage or loss of control.

How to Learn Online for Driver's License Point Deduction?

Online learning method for driver's license point deduction: Register on the online vehicle management office, and have your portrait photo taken during registration. The total learning duration is three hours, with the option to pause midway. Completion within the specified time is considered valid. During the learning process, the webpage will periodically pop up simple questions that require the learner to answer within a set time. Incorrect answers or exceeding the time limit will result in returning to the previous question point for re-learning. The learning results can be collected personally or mailed after two days. A driver's license is a certificate required by law for motor vehicle drivers. Driving a motor vehicle requires certain driving skills. Without these skills, driving a motor vehicle recklessly may lead to traffic accidents. Generally, individuals cannot drive on the road without a license.

Can an Engine Be Converted to Turbocharged?

An engine can be converted to turbocharged. Function of Turbocharging: It increases the air intake of the engine, thereby enhancing the engine's power and torque, making the car more powerful. After installing a turbocharger, the maximum power of an engine can increase by 40% or even more compared to when it is not equipped with one. Working Principle of Turbocharging: It uses exhaust gases to drive the exhaust turbine, which in turn rotates the intake turbine, thereby increasing the air intake. Components of Turbocharging: The turbocharging system for gasoline engines consists of two main parts: the turbocharger and the intercooler. The turbocharger compresses the air, and the intercooler cools the compressed air. The turbocharger itself is composed of the turbine housing and the compressor.

Will two screws on the license plate result in penalty points?

Using only two screws on the license plate is considered as not installing the license plate according to regulations, which will result in 6 penalty points and a fine ranging from 20 to 200 yuan. All four mounting holes of each license plate should be equipped with sealing devices. The seals must bear the Chinese character representing the province, autonomous region, or municipality directly under the central government, as well as the letter representing the issuing authority code. Each motor vehicle should be equipped with 8 new-style sealing devices. Except for cases where the vehicle has limitations, all four mounting holes of both front and rear license plates should be fitted with sealing devices. New traffic regulations on license plate screws stipulate: License plates can use fixed license plate frames, but the side edge of the frame must be more than 5cm away from the edge of the license plate number. Additionally, the license plate frame must not bear any logos, characters, decorative patterns, or obstruct the license plate.

What is the normal amount of lateral play for a motorcycle crankshaft connecting rod?

Generally, the lateral play of a motorcycle crankshaft connecting rod should not exceed 0.05 millimeters, although this may vary slightly depending on the model. Function of the crankshaft connecting rod mechanism: The function of the crankshaft connecting rod mechanism is to convert the thermal energy generated by fuel combustion into mechanical energy, transforming the reciprocating motion of the piston into the rotational motion of the crankshaft to output power. Composition of the crankshaft connecting rod mechanism: The crankshaft connecting rod mechanism consists of three main parts: the engine block group (including stationary components such as the cylinder block, crankcase, oil pan, cylinder liner, cylinder head, and cylinder gasket), the piston connecting rod group (including moving components such as the piston, piston rings, piston pin, and connecting rod), and the crankshaft flywheel group (including mechanisms such as the crankshaft, flywheel, torsional vibration damper, and balance shaft).

Is it possible to switch to different engine oil?

It is possible to switch to engine oils of different brands. Definition of engine oil: Engine oil refers to the lubricant specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. The base oils used in modern engine oils are composed of hydrocarbons, poly-alpha-olefins (PAO), and polyinternal olefins (PIO), all of which are organic compounds consisting solely of carbon and hydrogen. Some high-grade engine oils may contain up to 20% esters. Functions of engine oil: There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearing bushes. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby achieving the goal of reducing wear.
