Engine braking refers to the throttle pedal, located at the far right under the driver's foot, which is a trapezoidal pedal with a curved shape. Engine braking refers to the process of decelerating by releasing the throttle without depressing the clutch or shifting out of gear, utilizing the compression resistance, internal friction, and intake/exhaust resistance generated during the engine's compression stroke to brake the driving wheels. This allows the force of the rotating wheels to drive the engine. The braking effect is also related to the gear position—the lower the gear, the more pronounced the engine braking effect. Engine braking is an emergency braking method, typically used during long downhill descents or on icy/snowy road conditions. Generally, engine braking can cause significant damage to the vehicle, so it should be avoided under normal circumstances. Primary braking should rely on service brakes and parking brakes instead.

What speed should the car reduce to when downshifting from third gear to second gear?

When downshifting from third gear to second gear, the car should reduce its speed to 15-20 km/h. Whether upshifting or downshifting, the speed must match the gear. Only when the speed corresponds to the gear can the car's performance be at its best, and the thermal efficiency of the fuel be the highest. Below is an introduction to the speed matching for each gear: 1. First gear: Used when the speed is around 10 km/h. 2. Second gear: Used when the speed is around 20 km/h. 3. Third gear: Used when the speed is between 20-40 km/h. 4. Fourth gear: Used when the speed is between 40-60 km/h. 5. Fifth gear: Used when the speed is above 60 km/h.

Will the fuel decrease if a car is parked for a long time?

Gasoline and diesel are both volatile and flammable liquids, so the fuel will decrease if a car is parked for a long time. The following are the specific effects of long-term parking on a car: 1. Substandard engine oil: Lubricants, engine oil, and other fluids in the car may oxidize or absorb moisture, resulting in suboptimal performance when the vehicle is running. Substandard engine oil may even damage the engine. 2. Component deformation: After prolonged parking, the relative movement direction of the machine components inside the vehicle will become consistent, which may lead to deformation or misalignment over time, making driving extremely dangerous. 3. Battery discharge: The car battery relies on the engine running to charge itself. If the car is not started for a long time, the battery may remain in a discharged state, which will significantly shorten its lifespan.

What are the consequences of not inspecting a motorcycle?

Failure to inspect a motorcycle will result in fines and 3 demerit points. In the event of a traffic accident, the insurance company may refuse to compensate. Below are the specific details regarding motorcycle inspections: 1. Annual inspection regulations: Motorcycles are exempt from inspection within 6 years of initial registration. For motorcycles older than 6 years (inclusive), an annual inspection is required as per regulations. If a motorcycle fails the annual inspection, it must be repaired within a specified period. If it still fails after the deadline, the vehicle management office will confiscate its license plates and prohibit further operation. Motorcycles that do not undergo annual inspection without valid reasons or fail the inspection are not allowed on roads and cannot be transferred to another jurisdiction. 2. Scrapping regulations: The service life of a motorcycle is 13 years, after which it must be mandatorily scrapped. Additionally, if a motorcycle fails to undergo annual inspection for 3 consecutive inspection cycles after the expiration of its inspection validity period, it must also be mandatorily scrapped.

Why Do Motorcycles Run Faster Than Cars?

Because motorcycles usually have powerful engines relative to their size, providing ample surplus power. Here is some relevant information about motorcycles: Motorcycle Classification: Motorcycles are two or three-wheeled vehicles driven by gasoline engines and steered by handlebars to control the front wheel. They are lightweight, agile, and fast, widely used for patrols, passenger and cargo transportation, etc. They are a versatile, fast, economical, and comfortable mode of transportation. They combine the flexibility and portability of bicycles with the mobility and high-speed capability of cars. Broadly speaking, motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, touring bikes, etc. Disc Brake Adjustment: Generally, disc brakes do not require gap adjustment, as they are not designed with mechanisms for adjusting gaps. Therefore, if a disc brake rubs against the brake disc, it usually indicates component damage, such as excessive wear of the brake pads.

What is the Principle of Drifting?

The rear wheels lose most (or all) of their grip, while the front wheels must maintain their grip (at most losing a small portion, ideally even gaining additional grip). At this point, as long as there is a certain amount of lateral force on the front wheels, drifting will occur. Below is a detailed introduction to drifting: 1. Definition: Drifting is a racing term that refers to a series of maneuvers where the direction the car is pointing differs significantly from the actual direction of movement, causing the car to slide sideways through a turn. It is also known as "side slip," "skidding," or "fishtailing." 2. Applicability: Drifting is primarily used in performances or racing activities where road conditions vary greatly, with more frequent application in off-road rally racing. Other types of speed racing rarely use drifting techniques for turns. The main reason is that although drifting can maintain higher engine RPM during turns, it results in significant speed loss on regular asphalt roads, along with increased tire wear. Unless under special circumstances, drivers do not frequently use this technique during competitions.
