The function of the clutch master cylinder: It collects the pedal stroke information and enables the clutch to disengage through the action of the booster. When the clutch pedal is depressed, the push rod pushes the master cylinder piston to increase the oil pressure, which then enters the slave cylinder through the hose, forcing the slave cylinder pull rod to push the release fork and move the release bearing forward. When the clutch pedal is released, the hydraulic pressure is relieved, and the release fork gradually returns to its original position under the action of the return spring, causing the clutch to return to the engaged state. The clutch master cylinder is the part connected to the clutch pedal and linked to the clutch booster via an oil pipe. There is a radial long circular through-hole in the middle of the clutch master cylinder piston, and a directional screw passes through this hole to prevent the piston from rotating. The inlet valve is installed in the axial hole at the left end of the piston, and the inlet valve seat is inserted into the piston hole through a straight hole on the piston surface.

What is the issue with high temperature at idle speed?

Rust in the radiator causing poor water flow, unable to dissipate heat normally. Below is a related introduction about high temperature at idle speed: 1. Reasons for engine high temperature at idle speed: There is a water pump in the car's cooling system that forces the coolant to circulate. Additionally, there is a thermostat responsible for determining whether the coolant undergoes a small or large circulation. 2. Hazards of engine high temperature at idle speed: Due to prolonged idling, the engine temperature remains too low, leading to incomplete fuel combustion, which can easily cause carbon buildup, clog the fuel injectors, and severe carbon deposits may cause the piston rings to seize or even break. Prolonged idling also results in poor fuel atomization, where unburned atomized diesel condenses and washes down the cylinder walls, entering the lubricating oil, diluting and degrading it. This leads to insufficient lubrication for the engine's moving parts, accelerating engine wear.

What is the difference between Oshan and Changan?

Changan Automobile mainly targets the household passenger vehicle market, focusing on models such as sedans and SUVs; Oshan specializes in the passenger vehicle sector and is dedicated to providing driving and riding quality vehicles for China's 'big families.' Changan Oshan is a new passenger vehicle brand under the Changan Group, forming the 'one body, two wings' of Changan's independent passenger vehicle brand development together with Changan Automobile. Additional information: The Changan brand and the Oshan brand are two separate brands, but the Changan brand is the key brand of the Changan Group, while the Oshan brand is positioned as a more budget-friendly brand. The first model under the Changan Oshan brand is also a full-range vehicle, but overall, the materials and workmanship are slightly lower than those of the Changan brand. This can be seen as a strategic move by Changan, positioning it as a more budget-friendly model to increase market share. A high market share is very beneficial for the influence of an automotive brand.

What is the highway fuel consumption of Haval H6?

The comprehensive fuel consumption of Haval H6 reaches 6.8L/100km. The fuel consumption of a car varies slightly depending on each person's driving habits and skills. More stable driving habits result in lower fuel consumption, while aggressive driving habits such as frequent high-speed overtaking will appropriately increase fuel consumption. It is recommended to drive under various conditions and take the average value for a more accurate fuel consumption measurement. The high fuel consumption of Great Wall Haval H6 is mainly due to its relatively weak 1.5T power output and the vehicle's own heavy weight, which requires the engine to operate at high power, leading to slightly higher fuel consumption. Here are some factors that affect the fuel consumption of Haval H6: 1. Different driving habits. 2. Different road conditions, such as traffic congestion, load, fuel quality, use of air conditioning, whether the car is in the break-in period or an old car, etc., will also result in different fuel consumption. 3. Vehicle maintenance is also very important. Maintaining normal tire pressure levels is crucial; insufficient tire pressure will greatly increase rolling resistance. Reducing the car's load by removing unnecessary items from the trunk can lighten the vehicle's weight and achieve energy-saving effects. 4. Choosing a reasonable route is essential. Fuel consumption is highest when stuck in traffic.

What causes the clicking sound from the tires?

Tire noise can be caused by small stones stuck in the tread, which create a clicking sound when they hit the road surface. Below is some relevant information about tires: 1. Function of tires: Tires serve as the medium for transmitting forces between the vehicle and the road, including driving force, braking force, and steering force, enabling operations like acceleration, braking, and turning. 2. Classification of tires: Automobile tires can be divided into passenger car tires and truck tires based on their purpose. They can also be categorized into pneumatic tires and solid tires by their structure. 3. Composition: Tires with inner tubes consist of an outer tire, inner tube, and a flap. Tubeless tires are similar in appearance and structure but lack an inner tube and flap; instead, air is directly pressurized into the outer tire, with sealing ensured by the outer tire and the rim.

What does 45tfsi mean in Audi A6L?

TFSI stands for Turbocharged FSI engine, abbreviated as TFSI. The number 45 represents the vehicle's acceleration, with a higher number indicating stronger power. TFSI denotes a turbocharged engine that supports fuel stratified combustion technology. Here is an introduction to the 45tfsi in Audi A6L: 1. The Volkswagen series engines with direct injection (I), turbocharging (T), and mechanical (S) twin-charging are collectively referred to as TSI. 2. FSI stands for Fuel Stratified Injection. Fuel Stratified Injection technology is a type of lean-burn engine technology. T stands for turbocharging. 3. The FSI engine utilizes a high-pressure pump to deliver gasoline through a split rail (common rail) to electromagnetically controlled high-pressure fuel injectors. A key feature of the FSI engine is the generation of variable swirl in the intake tract, creating optimal swirl patterns for the intake air entering the combustion chamber. This promotes stratified filling, concentrating the air-fuel mixture around the spark plug located at the center of the combustion chamber.
