What is the Difference Between a 1.5L and a 2.0L Car?

What are the reasons for the engine warning light in a sedan?

There are several reasons why the engine warning light in a sedan may illuminate: 1. Poor or substandard gasoline quality: Low-quality gasoline not only affects the incomplete combustion of the air-fuel mixture in the cylinders, leading to excessive carbon deposits, but also poses risks such as clogging fuel lines and corroding components. 2. Oxygen sensor malfunction: The oxygen sensor is a highly durable component that can last for 3 years or longer as long as the fuel quality is adequate. It is necessary to check whether the oxygen sensor plug is loose. 3. Air flow sensor malfunction: If the air flow sensor or its circuit malfunctions, the engine control unit (ECU) will not receive accurate intake air volume signals, leading to improper fuel regulation. This can cause the air-fuel mixture to become too lean or too rich, resulting in the engine not functioning properly. Sometimes, this is accompanied by the illumination of the engine warning light.

Should You Engage the Handbrake First or Shift to P First When Parking an Automatic Car?

When parking an automatic car, it is acceptable to either engage the handbrake first or shift to P first. If parking on flat ground, neither sequence will cause damage to the vehicle's transmission, as it primarily depends on personal parking habits. However, when parking on a steep slope, it is advisable to follow this sequence: press the brake, shift gears, engage the handbrake, turn off the engine, and then shift to P. This method minimizes impact on the transmission. An automatic transmission eliminates the need for manual gear shifting by the driver, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic cars have six gear positions arranged from top to bottom: P, R, N, D, S, L.

What are the components of a torque converter?

A torque converter mainly consists of components such as the pump impeller, turbine, stator, and torque converter housing. It is a type of hydraulic transmission component, differing from a hydraulic coupling by the addition of a stator. The torque converter not only transmits torque from the engine but can also multiply the torque before delivering it to the transmission. From the moment the engine ignites, the torque converter begins to rotate. The connection and interruption of power are still managed by the clutch inside the gearbox. The only similarity between a torque converter and an MT clutch is the soft connection characteristic of the torque converter, which is similar to the semi-engaged condition of an MT clutch.

Can a Financed Car Be Sold?

A financed car can be sold, but the sale is not unrestricted when the loan is not fully repaid. This is because the vehicle is mortgaged to the bank during the loan period, and a vehicle with a mortgage registration cannot be freely bought or sold. When selling a financed vehicle, you can choose to complete the sale after the loan is fully repaid, or you can request the buyer to settle the outstanding amount in advance—both methods are viable for the transaction. Currently, most car financing agreements use a retention of title arrangement, meaning the ownership of the car remains mortgaged and does not belong to the consumer until the full payment is made. Due to this, there are frequent cases where consumers are deceived by unscrupulous car dealers.
