What is Fuel Consumption Rate?

2 Answers

Fuel consumption rate refers to the amount of fuel consumed by an engine operating at one kilowatt of power for one hour, also known as the brake-specific fuel consumption of a vehicle. It is commonly referred to as BSFC (Brake-Specific-Fuel-Consumption). Below is relevant information about fuel consumption rate: 1. Effective fuel consumption rate refers to the fuel consumption per unit of effective work, abbreviated as fuel consumption rate; measured in grams per horsepower-hour. It is a primary indicator for measuring the fuel economy of internal combustion engines. 2. For agricultural internal combustion engines, the fuel consumption rate is generally 170-220 (grams per horsepower-hour) for diesel engines; and 240-400 (grams per horsepower-hour) for gasoline engines.

I've been driving for over 20 years. Fuel consumption rate refers to the amount of fuel consumed by a vehicle over a certain distance, usually expressed in liters per 100 kilometers. For example, my car averages 7L/100km, meaning it uses 7 liters of gasoline for every 100 kilometers traveled. Many factors affect it - aggressive driving habits like sudden acceleration or braking can spike fuel consumption; SUVs consume more fuel than sedans; and traffic congestion also increases fuel usage. Developing good daily habits can improve this, such as maintaining steady speeds, reducing unnecessary weight in the car, regular maintenance including oil changes, and checking tire pressure. This saves money - my experience shows optimization can save thousands in fuel costs annually while extending vehicle lifespan, giving peace of mind when traveling.

Which is more harmful: exposing a car to direct sunlight or parking it under a tree?

Between parking a car under a tree and exposing it to direct sunlight, the latter is more harmful. Wind, sun, and rain can cause significant damage to a car over time. Issues such as paint aging and cracking, loss of body gloss, and rusting of metal parts are common problems that need to be addressed. 1. Accelerated aging of interior components: Car interiors are typically made of plastic, such as dashboards, which can deform under sunlight and produce abnormal noises. Seats, often made of fabric or leather, can harden and age in high temperatures, leading to poor tactile quality. 2. Impact on the vehicle's sealing performance: Many car parts are made of rubber, which is known to deform and age under high temperatures. Exposure to summer heat for eight to nine hours can easily cause aging, reducing the effectiveness of seals. Long-term exposure can lead to a decline in the vehicle's sealing performance.

How many days does it take to check for illegal U-turns over double yellow lines?

Generally, it takes 3-7 working days for the violation record to be available for online inquiry. 1. Reason: This is because the traffic police system requires some time to process and synchronize the information entry with the query system. However, this method is quite convenient as it allows you to check for any violations without leaving your home. 2. Double yellow lines: Double yellow lines are a common road traffic marking, consisting of two parallel solid yellow lines. They are typically placed in the middle of roads without a central divider to separate opposing traffic directions, dividing the lanes for vehicles traveling in opposite directions. Under normal circumstances, civilian vehicles are not allowed to cross these lines. Some roads with only simple small guardrails may also have double yellow lines. Vehicles can only make turns or U-turns at the broken sections of double yellow lines when other traffic signs permit.

Start the Engine First or Depress the Clutch?

Depress the clutch first to avoid starting the engine while in gear. The clutch is located inside the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. During driving, the driver can depress or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power from the engine to the transmission. Benefits of depressing the clutch: 1. Reduce starting load: When the vehicle is in neutral, although the engine input shaft gear is not engaged with the transmission power output gear, part of the engine's power is still consumed by components such as the clutch driven disc and output shaft. Depressing the clutch cuts off this consumption, thereby reducing the load on the starter and battery, and making the start smoother. 2. Prevent accidents: Some drivers are accustomed to using gears to park and do not have the habit of depressing the clutch when starting the vehicle. If they forget that the vehicle is in gear, the sudden movement during startup can cause a lurching phenomenon, increasing the risk of traffic accidents. 3. Extend engine life: If the driver does not depress the clutch, the engine can still start, but it will increase the burden on the starter and the current output of the battery, affecting the ignition effect of the engine. Over time, this can cause certain damage to the engine.

Why does the engine light stay on while the car runs normally?

The following are the reasons why the engine fault light is on: 1. Exhaust emissions do not meet standards: Poor fuel quality, failure of the three-way catalytic converter, excessive carbon buildup in the intake pipe, clogged fuel injectors, failure of the oxygen sensor, or occasional engine misfires can all cause the engine fault light to illuminate. Among these, poor fuel quality is the most common cause. 2. Poor system performance: The engine fault light may illuminate due to poor performance of the engine system, such as faults or poor electrical connections in the throttle pedal sensor, throttle position sensor, air flow meter, or crankshaft position sensor. 3. Transmission system faults: In some vehicles, faults in the transmission system, such as internal transmission issues, slipping, or overheating, are also indicated by the engine fault light.

Can you change lanes on a tunnel dotted line?

Tunnel dotted lines do not allow lane changes. Inside the tunnel, you should follow the vehicle in front in sequence and avoid changing lanes or overtaking. Because tunnels have fewer lanes and relatively poor visibility, you should slow down in advance before entering the tunnel, clearly observe the internal conditions, and maintain an appropriate distance from the vehicle in front at the specified speed. Precautions for driving through tunnels: Be especially careful when exiting the tunnel, as sometimes the sunlight outside can be blinding; other times, especially in long mountain tunnels, the weather might be fine before entering the tunnel, but there could be rain, snow, or thick fog at the exit, leading to accidents if unprepared. Some tunnel exits may also have curves or uphill/downhill slopes, and lack of anticipation can also cause accidents. If a vehicle breaks down or is involved in an accident inside the tunnel and cannot leave the scene immediately, turn on the hazard warning lights and place a warning sign 50 to 100 meters behind the vehicle. The driver and passengers should quickly exit the vehicle and leave the tunnel along the side to the roadside guardrail, then call the police immediately to avoid secondary accidents inside the tunnel.

What are the three types of brakes?

The three types of brakes are hydraulic brakes, mechanical brakes, and pneumatic brakes. Below is relevant information about brakes: 1. Function of brakes: To decelerate the vehicle as needed or bring it to a stop within the shortest distance, and to maintain a stable speed when driving downhill. 2. Usage of brakes: During driving, the service brake (foot brake) is generally used to facilitate deceleration and stopping while moving forward. It is not just for keeping the vehicle stationary. The parking brake is only used when the service brake fails. Once the vehicle comes to a complete stop, the parking brake (hand brake) should be engaged to prevent the vehicle from rolling forward or backward.
