Can I turn on the air conditioning immediately after starting the car in summer?

It is not recommended to turn on the air conditioning immediately after starting the car in summer. Here is the relevant information: Reasons not to turn on the air conditioning: It is not advisable to turn on the air conditioning right after starting the car, as this will increase the load on the engine when it has just started, leading to higher fuel consumption. After the engine is running normally, it can better support the operation of the air conditioning compressor. Best practice: Open the doors or windows to allow air circulation for a while before starting the car, then wait about a minute before turning on the air conditioning. In summer, it is generally better to turn on the air conditioning after the car has started moving.

What are the structures of a motorcycle carburetor?

A simple carburetor consists of three parts: upper, middle, and lower. The upper part includes the air intake and float chamber, the middle part has the venturi, jet, and spray tube, and the lower part includes the throttle valve. Function of the carburetor: The carburetor mixes air and gasoline in the correct proportion to provide combustion power for the cylinder. The carburetor has a throttle piston that moves up and down to control the amount of air intake. A needle valve passes through the main fuel jet in the middle of the throttle piston. The up and down movement of the throttle piston simultaneously drives the needle valve to control the fuel quantity. When the throttle is applied, the throttle cable drives this throttle piston to move up and down, providing combustion power to the cylinder and controlling the engine speed. Working process of the carburetor: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine's operation. Essentially, it atomizes the gasoline and mixes it with air.

What is the appropriate torque for a motorcycle oil drain bolt?

Motorcycle oil drain bolt torque is generally 22N-27N for cast iron oil pans and 15N-22N for all-aluminum oil pans. Motorcycle oil draining method: Open the waste oil pipe screw at the bottom of the carburetor, pull out the oil pipe connected to the carburetor, connect a section of pipe, and use a bottle to catch the oil. Precautions for motorcycle oil draining: When draining gasoline from the fuel tank, it should be stored in a sealed container. Otherwise, the "light components" in the gasoline will decrease over time, causing difficulty or failure in starting the motorcycle. At the same time, the gasoline in the carburetor should also be completely drained to prevent impurities in the gasoline from clogging the carburetor's metering holes, oil passages, and other components.
