What is the normal RPM when starting a car?

Starting a car with an RPM between 1200 and 1500 is normal. The engine speed relates to the number of work cycles per unit time or the effective power output of the engine. That is, the effective power of the engine varies with different speeds. When indicating the effective power of the engine, the corresponding speed must also be specified. The effective power and its corresponding speed specified on the engine's product label are referred to as the rated power and rated speed, respectively. The rated power is not the peak power the engine can produce but rather the effective power usage limit set based on the engine's purpose. The peak torque a car engine can output and its corresponding speed serve as an indicator for evaluating the engine's power performance.

What Causes the Engine Warning Light to Illuminate and the Vehicle to Shake?

The reasons for the engine warning light illuminating and the vehicle shaking are: 1. Poor combustion of the engine's air-fuel mixture; 2. Abnormal fuel supply pressure; 3. Wear of the spark plug electrode gap; 4. Faulty ignition coil; 5. Aging rubber components of the engine mount or transmission mount; 6. Clogged throttle body. The solutions for the engine warning light illuminating and the vehicle shaking are: 1. Replace the ignition coil and fuel injector; 2. Replace the spark plug components; 3. Replace the rubber components of the engine mount or transmission mount; 4. Clean the throttle body. The working principle of the engine is to generate kinetic energy by burning fuel in the cylinders, driving the pistons inside the engine cylinders to reciprocate, which in turn moves the connecting rods and cranks attached to the pistons in a circular motion around the crankshaft center, thereby outputting power.

Where is the cabin air filter located on the Roewe 550?

The cabin air filter of the Roewe 550 is located behind the engine compartment sealing strip. The steps to replace the cabin air filter are as follows: 1. Remove the clips of the sealing strip and pull the strip from left to right. 2. Then unscrew the screws at this position (one on each side). 3. Next, you will see the cabin air filter. 4. Grip the retaining strip and gently pull to remove the old filter. 5. Install the new cabin air filter (pay attention to the correct installation direction). The functions of the cabin air filter: 1. Filter dust particles from the air to prevent these pollutants from entering the car's evaporator and causing sludge buildup that could block it. 2. Filter dust, mist, pollen, carbon oxides, and sulfides from the air, as the filter contains activated carbon to adsorb harmful gases and particles.

What Are the Causes of Abnormal Noise in a Car Transmission?

The causes of abnormal noise in a car transmission are: 1. Bearing wear and damage can produce abnormal sounds during normal operation; 2. Loose bolts on the transmission housing; 3. Loose grooves in the gear lever and shift fork of a manual transmission; 4. Failure to replace automatic transmission fluid for an extended period, leading to direct friction between components and causing abnormal noise. The functions of a transmission are: 1. To change the transmission ratio, expanding the range of torque and speed variation of the driving wheels to adapt to frequently changing driving conditions, while allowing the engine to operate under favorable conditions; 2. To enable the car to reverse while the engine's rotation direction remains unchanged; 3. To use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output in the transmission.
