What is the function of the exhaust stroke?

The function of the exhaust stroke is to expel exhaust gases. Below is a detailed introduction to four-stroke engines: 1. Classification: Four-stroke engines belong to reciprocating piston internal combustion engines. Based on the type of fuel used, they are divided into three categories: gasoline engines, diesel engines, and gas fuel engines. Piston internal combustion engines that use gasoline or diesel as fuel are called gasoline engines or diesel engines, respectively. Piston internal combustion engines that use natural gas, liquefied petroleum gas, and other gaseous fuels are called gas fuel engines. Both gasoline and diesel are petroleum products and are traditional fuels for automotive engines. Non-petroleum fuels are called alternative fuels. Engines that use alternative fuels are called alternative fuel engines, such as ethanol engines, hydrogen engines, methanol engines, etc. 2. Working process: A four-stroke gasoline engine completes one working cycle through four strokes: intake, compression, power, and exhaust. During this process, the piston moves up and down four times, and the corresponding crankshaft rotates two revolutions.

What kind of car generally has a speedometer that goes up to 240 mph?

240 mph refers to a car whose speedometer has a maximum scale of 240 kilometers per hour. Here is some additional information: 1. Car odometer: The car odometer indicates the speed of the car, measured in km/h (kilometers per hour). It consists of two meters: one is the speedometer, and the other is the odometer. It is usually located directly in front of the driver's position. Identification methods include determining the wear level or checking the car's maintenance records at a 4S shop. 2. Car speedometer: The maximum scale on the car speedometer is called the "speedometer bottom." Generally, the maximum speed indicated on the car speedometer is based on the highest possible speed value under the engine's no-load maximum RPM. Therefore, the higher the speedometer bottom value, the better the performance of the car.

What are the penalty points for reverse parking?

Penalty points for reverse parking: Not following the prescribed route or sequence, deduct 100 points; Vehicle body crossing the line, deduct 100 points; Failing to park in the designated area, deduct 100 points; Stopping midway, deduct 100 points. Here is additional information: 1. Reverse parking: Reverse parking is a mandatory test item for obtaining a small car driver's license after 2013. It assesses the driver's ability to operate the vehicle in a confined space. Reverse parking is a key assessment point in the driver's test, which involves maneuvering the vehicle correctly into the garage from both sides while in motion. 2. Tips: Control the driving speed. Use first gear or reverse gear at idle speed throughout the process, maintaining the same speed as when starting.

How to Solve the Dashboard Engine Warning Light?

Solution for the dashboard engine warning light: When the engine warning light comes on, you should not continue driving. It is necessary to promptly visit a 4S shop or repair shop for inspection. During the inspection, a professional technician should use a specialized diagnostic computer to read the fault codes. After the engine warning light comes on, fault codes will be generated in the computer, which can be read using a professional diagnostic computer. The probability of the car's engine itself malfunctioning is relatively low, while the probability of faults occurring in the electronic systems and control mechanisms around the engine is relatively high. There are many sensors and control mechanisms around the car's engine. During regular maintenance, you can also have professionals use a diagnostic computer to read the fault codes, so that any issues with the car can be promptly identified.

How to Change Engine Oil at Home?

Here are the step-by-step methods for changing engine oil at home: 1. Prepare a bucket of engine oil that meets the lubrication standard, an original oil filter, an oil filter tool, an adjustable wrench or a wrench suitable for the size of the oil pan screw, an oil pan, a piece of cotton cloth, start the vehicle for about 1 minute to allow the oil to fully circulate, and then turn off the engine. 2. Open the oil filler cap, and use the tool to loosen the oil filter and oil pan screw. 3. Place the oil pan under the oil pan screw, completely loosen the oil pan screw, and drain the old oil until it stops flowing completely. 4. Tighten the oil pan screw and wipe off excess oil with a cotton cloth. Unscrew the old oil filter, it is recommended to pad with a cotton cloth to avoid burns, apply oil to the seal ring of the new oil filter, and tighten it clockwise. 5. Add new oil from the oil filler port, it is recommended to consult the 4S store in advance for the amount to be added, and tighten the oil filler cap after adding. 6. Restart the engine for 1-2 minutes, observe whether there is oil leakage at the oil pan screw and oil filter, if there is oil leakage, turn off the engine immediately for inspection and treatment; if there is no oil leakage, check the oil level on the dipstick after turning off the engine, and add to the standard position (the position slightly above the middle of the oil scale), the replacement is complete.

What are the differences between imported cars and joint-venture cars?

Here are the specific differences between imported cars and joint-venture cars: 1. Concept: Imported cars are imported as complete vehicles, while joint-venture cars are either fully domestically produced or assembled in China with some imported parts. Additionally, there may be some detailed modifications to the models. 2. Quality: The quality and craftsmanship of joint-venture cars are not inferior to those of imported cars. Domestic automobile manufacturers adopt production processes and standards that are in line with international practices, and the quality requirements are also very strict. 3. Suppliers: Joint-venture cars refer to finished vehicles produced domestically by foreign brands, while imported cars are finished vehicles imported entirely from abroad. Although their origins differ, there is not much difference in the supply of parts, as many components for imported cars are also produced and supplied domestically.
