The function of an electronically controlled automatic transmission is to select the optimal gear ratio for different loads and vehicle speeds, ensuring the engine operates at a corresponding stable speed. All gear shifts are performed automatically by the transmission, with the driver only needing to use the accelerator pedal to indicate their intent for speed changes and the gear selector to choose the desired operating mode. The electronically controlled automatic transmission is developed by adding an electronic control system to the traditional hydraulic automatic transmission. Common types of automotive automatic transmissions include: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch automatic transmission.

What Causes Sudden Cracks in Car Windows?

Specific reasons are introduced as follows: 1. External force: External force causing the glass to break, such as being hit by stones or similar objects. 2. Excessive temperature difference: A significant temperature difference between the inside and outside of the car may also be a factor. Due to the air conditioning being set too low and exposure to intense sunlight, the glass is prone to cracking under the effects of thermal expansion and contraction and uneven heating. 3. Car glass: Car glass is a type of laminated glass. When subjected to external impact, if the force is not enough to shatter it but causes a crack, the interlayer will separate due to air entering and atmospheric pressure. If driving continues, the crack area will expand, affecting visibility and driving safety. 4. Repair: The repair of car glass mainly involves filling the crack with liquid adhesive to eliminate the gap.

What is the adjustment method for the valves of a four-cylinder engine?

The adjustment method for the valves of a four-cylinder engine is: 1. Divide the number of cylinders into two equal parts, using the center as the axis of symmetry; 2. Two people cooperate, with one person rotating the crankshaft; 3. Adjust the valve clearance of a cylinder on the right side of the axis of symmetry, paying attention to the intake valve of the corresponding cylinder on the left side of the axis of symmetry; 4. When the valve moves slightly, adjust the valve clearance of this cylinder on the right side. The valve is composed of a valve head and a stem, and its function is to input air into the engine and discharge the exhaust gases after combustion. The effects of excessive valve clearance are: 1. It reduces the opening degree of the intake valve and shortens the opening time, leading to insufficient air intake and a decrease in engine power; 2. It causes poor exhaust, resulting in an increase in exhaust gases in the combustion chamber.
