What does engine compression ratio mean?

It refers to the ratio between the maximum and minimum volume of gas in the cylinder during piston movement. When the piston is at its lowest point, the gas volume in the cylinder is at its maximum (called total cylinder volume). When the piston is at its highest point, the gas volume is at its minimum (called combustion chamber volume). Below are relevant explanations: 1. Stroke form: All follow the four-stroke cycle - intake, compression, power, and exhaust. The intake and power strokes occur when the piston is at bottom dead center, while compression and exhaust occur at top dead center. 2. Mixture volume: If the cylinder volume is 10 when the piston is at bottom dead center, and the compressed mixture volume is 1 at top dead center, then the engine compression ratio is 10:1. Higher compression ratios generally improve fuel efficiency and power output, but excessive ratios can have adverse effects.

How to Interpret Traffic Lights for Turning?

Driving and interpreting traffic lights for turning are as follows: 1. Left Turn: At a circular traffic light, you can turn left when the light is green. At an intersection with an arrow traffic light, you should turn left when the left-turn arrow is green. 2. Right Turn: At an intersection with an arrow traffic light, you cannot turn right when the red right-turn arrow is lit. In all other cases, you can turn right. At an intersection with a 'No Right Turn' sign, you cannot turn right regardless of the light color. Relevant information about traffic lights is as follows: 1. Meaning: Traffic lights, also known as traffic signals, indicate whether vehicles and pedestrians can proceed. They are usually installed at intersections and other places requiring traffic control, generally consisting of red, green, and yellow lights. A red light means stop, a green light means go, and a yellow light means caution. 2. Green Light Signal: This is a permission to proceed. According to the 'Traffic Safety Law Implementation Regulations,' when the green light is on, vehicles and pedestrians are allowed to proceed, but turning vehicles must not hinder the passage of straight-moving vehicles and pedestrians. 3. Red Light Signal: This is an absolute stop signal. When the red light is on, vehicles must stop. Right-turning vehicles can proceed if they do not hinder the passage of other vehicles and pedestrians. 4. Yellow Light Signal: Vehicles that have already crossed the stop line when the yellow light turns on may continue to proceed. The yellow light signal's meaning is between the green and red light signals, serving both as a prohibition and a permission. When the yellow light is on, it warns drivers and pedestrians that the passage time is ending and will soon turn to red. Vehicles should stop behind the stop line, and pedestrians should not enter the crosswalk.

Should You Shift Directly to P Gear or First to N Gear Before Turning Off an Automatic Transmission Car?

The correct procedure for parking an automatic transmission car is to first shift to N gear, engage the handbrake, and then shift to P gear before turning off the engine. This method not only prevents damage to the car's transmission but also provides some protection. However, it is crucial to ensure that the vehicle has completely stopped moving or that the handbrake is fully engaged before turning off the engine. Additionally, when shifting gears while stationary, make sure the vehicle is in a braked state to prevent any unintended movement. Below is more information about automatic transmission cars: 1. Engine Start Limitation: For safety reasons, manufacturers have set limitations on gear positions when starting the engine. Generally, the engine can only be started when the gear lever is in P or N position. If the gear lever is in a driving position such as D or R, the engine will not start. This restriction is designed to prevent collisions with objects in front of or behind the car. If a beginner cannot start the engine, they should first check if the gear is in the wrong position. If it is not in P or N, adjust it accordingly before starting the car. 2. Shifting to Driving Gears: When starting the car to move, the brake pedal must be pressed before shifting the gear lever from P or N to a driving gear. Releasing the brake pedal will allow the car to move slowly. The purpose of pressing the brake beforehand is to ensure the safety of both the driver and the vehicle. Otherwise, if the engine starts and the car is shifted into a driving gear, it may move unexpectedly, increasing the risk of a collision if the driver is not quick to react. 3. Avoid Coasting in N Gear: Since automatic transmissions require lubrication, shifting to N gear while driving prevents the oil pump from supplying oil properly, leading to increased internal temperatures and potential severe damage to the transmission. Additionally, coasting in neutral at high speeds is very dangerous and does not save fuel. However, it is acceptable to shift to N gear when coasting to a stop at low speeds.

How long can the parking air conditioning be turned on?

The parking air conditioning can be turned on for 3-4 hours. More information about car air conditioning is as follows: 1. Car air conditioning is composed of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It is an air conditioning system used to adjust the temperature and humidity inside the car and provide a comfortable environment for passengers. 2. Car air conditioning generally has an internal and external circulation switch. When external circulation is used, the air conditioning draws air from outside the car, while internal circulation reuses the air inside the car. 3. Using internal circulation in car air conditioning can improve the cooling effect, but prolonged use of internal circulation will reduce the air quality inside the car. It is recommended to alternate between internal and external circulation to allow fresh air to enter the car and improve air quality.

What does it mean when the engine symbol flashes yellow?

When the engine symbol flashes yellow, it indicates a fault on the dashboard. The reasons are as follows: If the yellow light on the dashboard comes on while driving, it means the vehicle's engine requires maintenance/service. At this point, it is generally advisable to promptly inspect the engine or visit a nearby auto repair shop for maintenance/service. Since the engine is the heart of the vehicle, regular and timely maintenance is crucial to avoid breakdowns during use. 1. There are several ways the engine fault light can illuminate: steady yellow light, flashing yellow light; steady red light, flashing red light. If the red light is on, immediately go to a 4S shop for inspection and repair, as the fault is severe. If the yellow light is on, the fault may not affect driving, but it is still recommended to get it checked as soon as possible. 2. The vehicle can read fault codes via the OBD interface using a computer. If you are interested in the vehicle's mechanical/electronic systems, you can purchase a Bluetooth module for the OBD interface, allowing you to view and clear fault codes using a laptop or Android phone.

How to Position Your Feet for Manual Transmission?

When driving a manual transmission car, the right foot controls the accelerator and brake, while the left foot is solely responsible for the clutch. During normal driving, when not shifting gears, the left foot generally rests to the left of the clutch pedal, and the right foot remains on the accelerator. If no acceleration is needed, the right foot should rest steadily on the accelerator, and the brake should be pressed when deceleration is required. Below is more information about manual transmission driving: 1. Proper Use of the Clutch: When pressing the clutch, ensure it is fully depressed to ensure smooth gear shifting, avoiding gear grinding or popping out of gear. Releasing the clutch involves three stages: effective travel, engagement travel, and free travel. The technique involves two fast actions, two slow actions, and a pause. 2. Coordination Between Clutch and Accelerator: Good clutch-accelerator coordination is essential for smooth hill starts and handling traffic jams. Important reminder: Never press the clutch fully while giving gas, as this can easily accelerate clutch wear or burn out the clutch plate. The burnt smell often noticed in manual transmission cars is usually due to this reason. 3. Matching Speed and Gear: Beginners can initially decide gears based on speed. For example, on flat roads: Upshifting: Shift to second gear at 15 km/h; third gear at 25 km/h; fourth gear at 35 km/h; fifth gear at 45 km/h. Downshifting: Shift to fourth gear at 40 km/h; third gear at 30 km/h; second gear at 20 km/h; first gear at 10 km/h (summarized as: upshift at multiples of 5, downshift at multiples of 10). As driving skills improve, there will be no need to look at the speedometer. Instead, gear shifts should be determined by the engine sound and changes in vehicle power, which enhances driving safety.
