The symptoms of a bad camshaft include difficulty in ignition, hard starting, unstable idle, inability to accelerate, weak engine power, car shaking, persistent illumination of the malfunction indicator light, sudden stalling when the engine is hot, jerky driving, and accelerated engine wear. The camshaft is a component in a piston engine, and its function is to control the opening and closing of the valves. The main body of the camshaft is a cylindrical rod approximately the same length as the cylinder bank, with several cams attached to it for driving the valves. The camshaft is supported within the camshaft bearing bore by camshaft journals, so the number of camshaft journals is an important factor affecting the support stiffness of the camshaft.

What are the functions of engine oil?

The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear; 2. To bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; 3. To circulate carbon deposits, sludge, and metal wear particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. The classifications of engine oil are: 1. Conventional mineral oil; 2. Semi-synthetic oil; 3. Fully synthetic oil. The signs that engine oil needs to be changed are: 1. Check the viscosity of the oil—if there is no viscosity, the oil needs to be changed; 2. The color of the oil is black; 3. There are too many black particles, metal shavings, or carbon deposits in the oil; 4. The smell of the oil is abnormal.

Which buttons to press for defogging in rainy weather?

To defog your car in rainy weather, press the windshield heating button and the front windshield defrost button, which are marked with symbols resembling a windshield. The reason for fogging in rainy weather is the temperature difference between the inside and outside of the car, where the inside temperature is higher than the outside, causing water molecules in the air inside to condense into mist upon cooling. Methods to defog your car in rainy weather include: 1. Wipe clean with a towel; 2. Turn on the car's heater to clear the fog; 3. Use the air conditioning's cooling and dehumidifying function to reduce air humidity; 4. Apply an automotive glass anti-fog agent. Maintenance methods for car window glass include: 1. Use appropriate glass cleaner according to the season; 2. Apply automotive glass insulation film. The functions of car window glass are: 1. To shield against wind and rain, and reduce noise; 2.
