What is the state of the exhaust valve at top dead center?

When the piston is at the top dead center position of the exhaust stroke, the exhaust valve is about to close, while the intake valve is about to open. Introduction to automobile exhaust pipes: Automobile exhaust bellows, also known as automobile exhaust pipe hoses, are installed in the exhaust pipe between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system to reduce vibration and noise. Function of automobile exhaust pipes: For the automobile body, the exhaust pipe serves to reduce vibration and noise, and extends the life of the exhaust muffler system. Its main working principle is to divert the airflow through multiple channels, where the friction and collision between these channels gradually reduce the airflow velocity. This cycle repeats, ultimately allowing the exhaust gas to be discharged through the automobile's exhaust pipe, thereby reducing noise.

Why is there abnormal noise from the exhaust pipe at idle?

Abnormal noise from the exhaust pipe at idle may be caused by intake manifold leakage, incorrect ignition timing (either too early or too late), or improper idle adjustment. Specific reasons: Clogged three-way catalytic converter; The exhaust pipe and engine are connected by a flexible joint, which may have been damaged or aged due to prolonged use, causing abnormal noise; Water accumulation in the exhaust pipe can also cause abnormal noise. Solutions: Regular cleaning of the three-way catalytic converter can eliminate abnormal noise from the exhaust pipe. Block the right exhaust pipe with a towel and rev the engine to expel water from the left pipe, or use a straw to suck it out.

How much is the speeding when driving at 140 in an 80 speed limit zone?

Speeding = (Current speed - Speed limit) ÷ Speed limit × 100 = (140 - 80) ÷ 80 × 100% = 60 ÷ 80 × 100% = 75%. Exceeding the speed limit by 75%. According to regulations, a warning is issued for speeding less than 10% with no points deducted or fines imposed; speeding between 10% and 20% results in a 3-point deduction and a fine; speeding between 20% and 50% results in a 6-point deduction and a fine; speeding over 50% results in a 12-point deduction, temporary suspension of the driver's license, and mandatory training. More relevant information is as follows: 1. Develop the habit of wearing a seatbelt when getting in the car: The importance of seatbelts for driving safety is self-evident, and many bloody examples have warned that you must fasten your seatbelt when entering the car. However, there are always some people who feel that seatbelts restrict their movement space or even find them uncomfortable and choose not to wear them. Such behavior must be firmly resisted. 2. Ensure the car door is tightly closed when driving: For female drivers, it is not uncommon for the car door to be not fully closed—since female drivers tend to close the door with less force compared to male drivers, the door may sometimes not be tightly closed. In the event of an accident, a loosely closed door could lead to fatal consequences.

Is It Normal for the Engine to Be Hot to the Touch in Summer?

It is quite normal for the engine to be very hot in summer. Engine Introduction: An engine is a machine that converts other forms of energy into mechanical energy. It can refer to either the power-generating device or the entire machine including the power unit. Engine Water Temperature: The optimal water temperature for a car while driving is around 90 degrees. If the temperature warning light on the dashboard comes on, it is advisable not to continue driving. You should stop and check the car's cooling system. If the issue is minor, wait for the temperature to drop before driving to a service station for inspection and repair. When cooling down, never pour cold water on the engine, as this may cause the engine block to crack due to sudden cooling.

What does a five-door five-seat hatchback mean?

A five-door five-seat hatchback refers to an MPV model with a large rear hatch door. Simply put, a four-door five-seat model is a sedan (three-box design), while a five-door five-seat model is a hatchback (two-box design). The term 'five-door' means the car has five doors: front left and right doors, rear left and right doors, plus the trunk lid. 'Five-seat' indicates there are five seats inside the car: two in the front (driver and passenger seats) and three in the rear. More relevant information is as follows: 1. Introduction: A hatchback (Hatchback) is a type of car body design. In addition to two to four side-opening doors, it typically features a vertical tailgate or an inclined rear window door to access the luggage compartment, which is the main visual characteristic of a hatchback. 2. Configuration: From a structural perspective, the passenger compartment of a hatchback is usually integrated with the rear luggage area without any fundamental structural separation. Therefore, it can be considered as a cabin with a complete luggage compartment. This is why hatchbacks are often referred to as 'two-box cars.' Most small cars you see are hatchbacks.

Why is there an abnormal noise in the engine?

Abnormal noise in the engine may be caused by engine oil. Causes of abnormal noise: Abnormal noise in the engine indicates that the technical state of a certain mechanism has changed. It is mainly caused by excessive wear of some parts or improper assembly and adjustment. The transmission has many parts, and the causes of noise are also relatively complex. Solutions: Abnormal noise can also indicate that the engine may suffer accidental damage. Therefore, when abnormal noise occurs in the engine, it should be repaired in time to prevent the fault from expanding. If the abnormal noise is inside the engine, most car owners cannot solve it by themselves, and it is best to send it to a factory for inspection and repair. If the transmission noise is obvious, it is still recommended to send it to a professional repair shop to check the faulty parts and then replace them.
