What is the reason why the carburetor of the grass trimmer cannot pump oil?

It may be due to oil level control failure. The following is a related introduction to the carburetor: Introduction: The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine operation. As a precise mechanical device, the carburetor utilizes the kinetic energy of the incoming air flow to atomize the gasoline. Its important role in the engine can be referred to as the "heart" of the engine. A complete carburetor device should include a starting device, idle device, medium load device, full load device, and acceleration device. Function: It effectively provides the engine with a mixture of gasoline and air (theoretically the best ratio is 1:15). The performance of the engine is determined by itself, and the carburetor cannot improve the engine's inherent capabilities, but it can help the engine perform at 100% of its potential.

Where is the car radiator located?

The radiator is generally located behind the air conditioning condenser. Here is some relevant information about car radiators: 1. You can see the radiator cover by opening the engine compartment, but you need to remove the front bumper cover to clearly see the radiator's position. 2. The car radiator, also known as the heat exchanger, is a key component in the vehicle's cooling system, designed to dissipate heat. 3. The "water" added to the radiator mainly refers to antifreeze. While water is technically a type of coolant that can also lower engine temperature, using plain water alone is considered a low-grade cooling solution. It's season-dependent and prone to causing scale and rust. In contrast, dedicated coolant works year-round, offers higher quality, and ensures reliable performance.
