The function of an automotive transmission is: 1. To change the transmission ratio and expand the range of torque and speed variations of the driving wheels, adapting to frequently changing driving conditions and allowing the engine to operate under favorable working conditions; 2. To enable the vehicle to reverse while maintaining the same rotation direction of the engine; 3. To interrupt power transmission using neutral gear, allowing the engine to start, idle, and facilitating gear shifting or power output. The maintenance methods for an automotive transmission include: 1. Regularly changing the transmission fluid; 2. Frequently checking the fluid level; 3. Avoiding coasting in neutral gear; 4. Periodically cleaning the transmission; 5. Avoiding forced gear disengagement; 6. Reducing the time spent idling to warm up the engine.

The transmission is like a little helper for the engine when driving—it adjusts the engine's power output according to different road conditions. For example, when starting or climbing a hill requires more force, it shifts to a lower gear to increase thrust; once the speed picks up, it switches to a higher gear to let the engine run smoothly and save fuel. When I drive a manual, I've noticed that shifting at the right moment makes the car more responsive with better acceleration and quieter operation at high speeds. The transmission also protects the engine from overworking, extending the car's lifespan and preventing failures caused by fixed RPMs. In stop-and-go city traffic, an automatic transmission is more hassle-free, as it handles all the changes automatically. Overall, it's the key component that ensures efficient power delivery, making driving smoother, safer, and more economical.

What is the principle of the Toyota Camry Hybrid?

Toyota Camry Hybrid adopts a series-parallel hybrid system. In its power coupling mechanism, the motor MG1 and the engine need to undergo planetary gear speed coupling. After speed coupling, torque coupling with motor MG1 is also required. Through speed synthesis, motor MG2 adjusts the engine speed, making the engine speed independent of the vehicle speed, thereby achieving the ECVT function. The Camry is a model under GAC Toyota. In terms of body dimensions, it measures 4900mm in length, 1840mm in width, and 1455mm in height, with a wheelbase of 2825mm.

What does gear oil 85w140 mean?

Gear oil 85w140 indicates that the gear oil is a multi-grade oil with two grades, 85w and 140, suitable for ambient temperatures ranging from -26°C to +50°C. In 85w140 gear oil, the 85 represents the low-temperature viscosity—the smaller the number, the lower the viscosity, resulting in better low-temperature fluidity and enhanced low-temperature performance. The 'w' stands for winter-grade gear oil. The 140 denotes the high-temperature viscosity—the larger the number, the higher the high-temperature viscosity, allowing it to withstand higher temperatures. Gear oil primarily refers to the lubricating oil used in transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance characteristics. Gear oil mainly functions to lubricate gears and bearings, prevent wear and rust, and assist in dissipating heat from the gears.

Is It Useful to Flush the Three-Way Catalytic Converter with Water?

Flushing the three-way catalytic converter with water is not effective; specialized three-way catalytic converter cleaning agents should be used for cleaning. The three-way catalytic converter is an important external purification device installed in the automotive exhaust system, which converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Since fuel contains harmful substances like sulfur and phosphorus, chemical complexes can form on the surface of the oxygen sensor and inside the three-way catalytic converter after combustion. Additionally, due to poor driving habits or prolonged driving in congested areas, the engine often operates in an incomplete combustion state, leading to carbon deposits in the oxygen sensor and three-way catalytic converter. Therefore, regular cleaning of the three-way catalytic converter is necessary.

How to Turn Off Mazda's Auto Start-Stop?

Method to turn off Mazda's auto start-stop: There is an i-stop auto start-stop button on the vehicle's center console. Press and hold this button until the dashboard light turns yellow, which indicates the auto start-stop system is deactivated. Mazda's i-stop system employs a unique "combustion restart" method. During engine restart, the starter motor plays only an auxiliary role, with the main starting force coming from the pre-compressed cylinder before shutdown. Mazda is a Japanese multinational automobile manufacturer, and its SUV lineup includes the CX3, CX30, CX4 (exclusive to China), CX5, CX8, and CX9. Taking the Mazda CX5 as an example, it is positioned as a compact SUV. In terms of body dimensions, its length, width, and height are 4555mm, 1840mm, and 1710mm respectively.
