What is the engine RPM at a speed of 120km/h on the highway?

Different car brands have different RPMs. The RPM also varies depending on the gear. Under normal conditions, at a speed of 120km/h on a flat road, most vehicles' engine RPM should be between 2500 and 3000. Factors affecting engine RPM: The RPM of a car is determined by the engine, which is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines, jet engines, electric motors, etc. To bring a stationary engine into operation, an external force must first be applied to rotate the engine crankshaft, causing the pistons to start moving up and down, allowing the intake of combustible mixture into the cylinders, and then proceeding to the subsequent working cycles. The system that provides this external force is the starting system. The engine RPM is related to the number of work cycles per unit time or the effective power output of the engine, meaning the effective power of the engine changes with different RPMs. Therefore, when specifying the effective power of an engine, the corresponding RPM must also be indicated.

How many points will be deducted for not wearing a seatbelt in the front passenger seat while driving on the highway?

Not wearing a seatbelt in the front passenger seat on the highway does not result in point deduction but incurs an appropriate fine. According to the Road Traffic Safety Law, when a motor vehicle is in motion, passengers in the front seat should also use seatbelts. Relevant details are as follows: Article 51 of the 'Road Traffic Safety Law of the People's Republic of China' stipulates: When a motor vehicle is in motion, the driver and passengers must use seatbelts as required, and motorcycle drivers and passengers must wear safety helmets as required. Article 89 stipulates: Pedestrians, passengers, and non-motor vehicle drivers who violate road traffic safety laws and regulations regarding road passage rules shall be given a warning or fined; non-motor vehicle drivers who refuse to accept the fine may have their non-motor vehicles detained. Correct way to fasten a seatbelt: Hold the buckle lock and latch, slowly pull out the waist and shoulder belt, ensuring the shoulder belt passes over the shoulder and fits close to the neck, snugly and comfortably against the body. Ensure the waist belt is below the abdomen and as low as possible, also fitting snugly against the body. Finally, insert the belt buckle into the lock. Both the driver and the front passenger must wear seatbelts, not only for safety reasons but also to avoid penalties from traffic police for violations.

How to Handle Speeding Violations on Highways?

When driving on highways, vehicles must comply with relevant regulations and road signs, and speeding is prohibited. If speeding occurs, corresponding violation penalties will be imposed. The details are as follows: Highway speeding violations are categorized into out-of-province highway violations and within-province highway violations. Within-province highway violation handling: Pay fines at the traffic police station in the vehicle's registered location, or at the nearest traffic police station. If the violation occurs within the province where the vehicle is registered, it can be handled at any traffic police station within the province, and online processing is also available. Out-of-province highway violation handling: Processing can be done through legal agencies such as post offices after confirming the speeding violation. Alternatively, friends or relatives in the location where the violation occurred can be entrusted to handle it. Highway speeding fine standards: Speeding less than 10% on highways or national roads results in a warning, no points deducted, and no fine, with no need to undergo processing; speeding between 10% and 20% incurs 3 points deducted and an appropriate fine; speeding between 20% and 50% results in 6 points deducted and an appropriate fine; speeding over 50% leads to a one-time deduction of 12 points, an appropriate fine, with penalties increasing according to the speed exceeded. Speeding between 20% and 50% on highways results in 6 points deducted and an appropriate fine.

What is the normal engine speed when driving on the highway?

When driving on the highway, the engine speed should generally be between 1000 and 3500 RPM. Around 3000 RPM, the engine outputs the maximum torque, after which it becomes inversely proportional to the driving speed. Maintaining around 3000 RPM is ideal. Details are as follows: During normal use, it is generally recommended to maintain around 3000 RPM. Avoid situations of low gear with high speed or high gear with low speed. Between 2000 and 3000 RPM, low gear with high speed makes the engine work harder but consumes more fuel, which is better for climbing hills. High gear with low speed strains the engine, and prolonged use can damage it, though it may save a little fuel. This can harm the engine. While driving, the optimal engine speed for most fuel-injected cars is around 2200 to 2500 RPM. Regardless of the gear, try to keep the engine speed around 2200 to 2500 RPM. Too low a speed results in insufficient driving power, higher fuel consumption, and potential engine damage. Too high a speed increases unnecessary fuel consumption and can also damage the engine. The most fuel-efficient driving condition is maintaining a constant speed in a straight line. The most fuel-efficient speeds are: 60 to 80 km/h for small-displacement cars and 80 to 100 km/h for medium-displacement cars. When shifting gears, slightly increase the throttle a bit more than during normal driving to raise the tachometer to just above 2500 RPM. If shifting below 2000 RPM, the speed will drop further after shifting, creating a feeling of gear disengagement, which actually consumes more fuel.

What Causes the Golf Dashboard Not to Light Up?

Reasons for the Golf dashboard not lighting up: fuse damage, vehicle unable to charge, car battery dead. Fuse damage: The circuit or appliance behind the fuse is grounded; the appliance behind the fuse malfunctions, increasing power consumption; the appliance behind the fuse starts frequently, meaning the frequency of startup and shutdown exceeds normal usage patterns. Solution: Go to a 4S shop for professional repair as soon as possible. Vehicle unable to charge: When the electric Golf is connected to a DC charging pile for charging, the charging gun is inserted into the vehicle's DC charging socket, but the DC charging pile's APP still prompts "Gun not inserted, please insert the charging gun to proceed," meaning DC charging cannot proceed normally. Solution: First, check whether the charging circuit connection is reliable, inspect whether the connection wire and plug are in good contact, carefully check the socket and plug for signs of arcing, and look for any line damage or breakage. Car battery dead: If the car battery is dead, the car will exhibit symptoms such as the dashboard light not turning on, car lights dimming, and the horn not sounding. In this case, promptly inspect the car battery and charge it. If the battery is damaged, it can be replaced with a new one.

What to Pay Attention to When Starting to Drive a Manual Transmission Car

When starting to drive a manual transmission car, precautions include avoiding simultaneous pressing of the brake and clutch, and preventing excessive use of the half-clutch state. Avoid simultaneous pressing of the brake and clutch: For beginners, pressing the clutch and brake together or pressing the clutch first and then the brake can make it easier to stabilize the car and avoid vehicle shaking or stalling caused by gear dragging. In fact, the smoothness of the vehicle comes at the cost of clutch wear. If you always drive in this way, the lifespan of the clutch may be only about 1/4 or 1/5 of its normal lifespan. Prevent excessive use of the half-clutch state: This situation often occurs due to traffic jams or other reasons that cause the car to move too slowly, making some beginners afraid of losing control of the vehicle speed. Keeping the clutch in the half-clutch state for a long time will accelerate the wear of the clutch plate and significantly shorten the clutch's lifespan. The correct approach is, when encountering situations like traffic jams or reversing that require careful control of vehicle speed, you can fully press or release the clutch at the appropriate time, using only the gear and brake to control the vehicle speed, and minimize the time the clutch spends in the half-clutch state.
