What is the role of the engine in a car?

The role of the engine in a car: It is the device that provides power to the car, serving as the heart of the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrids, among others. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to output power externally. The engine consists of five major systems and two main mechanisms. The five major systems are the fuel supply system, cooling system, lubrication system, ignition system, and starting system. The two main mechanisms are the crankshaft connecting rod mechanism and the valve train mechanism.

How to Repair a Broken Air Conditioning Compressor?

Repair methods for a broken air conditioning compressor: 1. Add an appropriate amount of Freon; 2. Replace the power supply line clip and use sandpaper to clean the surface of the compressor terminal; 3. Reorganize the connecting pipes between the indoor and outdoor units to reduce the workload of the compressor; 4. If the air conditioning power supply is aging, replace it promptly. A compressor is a type of driven fluid machinery that converts low-pressure gas into high-pressure gas, serving as the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via piston movement driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. Depending on the working principle, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

Can an automatic transmission driver's license drive a manual-automatic transmission car?

An automatic transmission driver's license can drive a manual-automatic transmission car, as a manual-automatic transmission car also falls under the automatic transmission category.

In fact, manual-automatic transmission is a type of automatic transmission, so it is permissible. Automatic transmission typically refers to the car's automatic gear-shifting mechanism, where the automatic transmission's control system automatically selects the appropriate gear based on the engine's speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L.
