How Many Liters of Fuel Does a 245-Horsepower Engine Consume at Idle for One Hour?

Should the clutch be pressed when performing intermittent braking in first gear during Subject 3?

Subject 3 intermittent braking in first gear does not require pressing the clutch. Relevant information is as follows: Principle: Intermittent braking means lightly pressing the brake and then releasing it, repeating this action to gradually reduce the speed. During this process, there is no need to press the clutch, but it is important to note that the force applied to the brake should be light, not too strong, to avoid stalling the engine. After all, the speed in Subject 3 is not very high, generally around 25-40km/h. Application: When using intermittent braking, for example, when approaching a crosswalk, it can be applied 50 meters in advance. Do not wait until the last moment to use it, as intermittent braking is not as effective as continuous braking, to avoid point deductions.

Do You Need to Press the Brake to Start a Car?

Except for models with one-button start, most other models can be started without pressing the brake. Strictly speaking, starting without pressing the brake will not cause any damage to the car. However, for manual transmission models, if the gear is not in neutral before starting, the vehicle may lurch forward upon ignition, potentially causing collisions and damage. For manual transmission models, pressing the brake while starting is the default practice. This is because early manual transmission models made it difficult to ensure the gear was in neutral and the clutch fully depressed before starting. To prevent the dangerous situation of the vehicle lurching forward during startup, it became common practice to press the brake while starting. With advancements in technology, many modern manual transmission models now have sensors on the clutch pedal, preventing the vehicle from starting unless the clutch is fully depressed. Therefore, current manual transmission models require both the clutch and brake to be pressed before starting. For automatic transmission vehicles, as long as the gear is in Park (P) or Neutral (N), there is no risk of the vehicle lurching upon startup. However, the habit from driving manual transmissions has carried over to automatic transmissions. Gradually, some automatic transmission models have been designed to require the brake to be pressed before starting, encouraging all drivers to develop the good habit of pressing the brake when starting the car.

What happens if water enters the car's air intake? Does it affect the engine?

Water entering the engine's air intake can indeed affect the engine. Detailed explanation as follows: When the damage is minor: The lifespan of the repaired engine depends on the extent of the damage. If the engine only took in water without any other damage, you simply need to remove the spark plugs to drain the water, then replace the engine oil and coolant. In this case, there is no impact on the engine itself, and its lifespan remains the same as a normal car. When the damage is severe: If water enters the engine cylinders along with the air intake, the situation becomes complicated. Water in the cylinders can cause the connecting rods to bend or even break, potentially damaging the engine block. In such cases, it's difficult to assess the damage without disassembling the engine to replace the connecting rods or even the engine block. After such repairs, whether the engine can function properly is uncertain, as it depends on the quality of both the repairs and the replacement parts. If the engine is damaged by water and requires disassembly, proper repairs can restore it to normal operation. However, if the parts are of poor quality or the repair work is substandard, the engine may develop problems during future use.

What are the requirements for the reverse parking test in Subject 2?

Subject 2 reverse parking requirements are as follows: Route: Driving not in accordance with the prescribed route sequence, deduct 100 points. Reverse parking: Not completely reversing into the parking space, deduct 100 points; vehicle body crossing the line, deduct 100 points. Stopping midway, deduct 100 points. Below is more information about Subject 2: Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment, referred to as the field driving skill test. The test items include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope, turning at a right angle, and curve driving. Notes: If you fail the Subject 2 test once, you can retake it once. If you do not take the retest or fail the retest, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled tests for Subject 2 and Subject 3 road driving skill tests must not exceed five. If the fifth scheduled test is still failed, the results of other subjects that have been passed will be invalidated.

Can a Vehicle with a Transplanted High-Displacement Engine Pass Inspection?

Transplanting a high-displacement engine will prevent a vehicle from passing inspection. According to Article 25 of the 'Measures for the Registration of Motor Vehicles of the People's Republic of China,' the following circumstances will result in the refusal of transfer registration: the motor vehicle owner arbitrarily modifies or replaces the motor vehicle or its files. Vehicles with unregistered engine replacements will definitely fail the annual inspection. Relevant regulations are as follows: Article 13 stipulates that motor vehicles registered for road use must undergo regular safety technical inspections based on legal and administrative regulations, considering factors such as vehicle purpose, passenger and cargo capacity, and service life. Article 11 states that driving a motor vehicle on the road requires displaying the vehicle license plate, inspection qualification mark, insurance mark, and carrying the vehicle registration certificate. Therefore, vehicles that do not undergo annual inspections are not permitted on the road; if discovered, they will be impounded and the owner fined.
