How to Deal with Hard Braking?

Here are the methods to handle hard braking in cars: 1. When braking, users should try to minimize the braking distance to protect the brake pads. First, use the engine's braking effect by downshifting to reduce speed, then lightly press the brake pedal. This shortens the braking distance and reduces wear on the brake pads. 2. Pay special attention to maintaining a safe distance during daily driving, decelerate in advance, and avoid sudden braking. Especially when the traffic light at an intersection is flashing, do not force your way through. 3. During normal driving, if you are not using the brakes, your foot should be off the brake pedal. Even resting it lightly on the pedal is not advisable, as it can easily increase wear on the brake pads. It is important to develop the habit of immediately releasing the pedal and lifting your foot after braking.

How often should the spark plugs of Baojun 560 be replaced?

Baojun 560 spark plug replacement cycle: Under normal maintenance conditions, they should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. How spark plugs work: The ground electrode of the spark plug is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the center electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the center electrode, it ionizes the medium between the center electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.

What gear should an automatic car be in when parked on a slope?

Automatic cars parked on a slope can be placed in the following two gears: 1. D gear: Since some automatic cars come with hill-start assist, when in D gear, you need to master the throttle and coordinate with the brake to achieve a smooth start on a steep slope. 2. On steep slopes, it is recommended to use manual mode, specifically the S+ gear in the S mode. This gear is the lowest in manual mode, offering the highest torque and force, and when coordinated with the brake, it can complete the hill start. Here is some relevant information about automatic cars: 1. Most automatic cars have P gear (Park), R gear (Reverse), N gear (Neutral), and D gear (Drive). It is important to use the automatic transmission properly to save fuel more efficiently. 2. When using D gear to climb a slope, if pressing the accelerator does not provide the same power as on flat roads, you should immediately switch to a low-speed gear with high torque. This not only saves fuel but also reduces engine wear. When encountering an uphill on city roads, avoid suddenly accelerating. Instead, accelerate before the uphill to increase speed.

What are the issues if a gasoline car is filled with diesel engine oil?

Filling a gasoline car with diesel or diesel engine oil can cause difficulties in starting the vehicle. During driving, the exhaust pipe may emit smoke, and there is a high likelihood of damage to the catalytic converter. Below is an introduction to the related content: Although both gasoline and diesel engines are internal combustion engines, diesel has a lower auto-ignition point, around 220°, whereas gasoline has a much higher ignition point, between 410° and 430°. Therefore, diesel engines use compression ignition and do not require spark plugs for ignition. They rely on compressing air to raise the temperature to the diesel's ignition point, then inject diesel, which auto-ignites. Consequently, if diesel enters a gasoline engine, it will start burning violently on its own before the spark plug ignites, causing abnormal pressure in the combustion chamber, commonly known as knocking. This will also be accompanied by other engine abnormalities. Once it is discovered that the issue is caused by mistakenly adding diesel, it is crucial to stop attempting to start the engine to prevent diesel from entering the fuel system. Then, take the car to a 4S shop or repair shop to drain the diesel completely and refill it with gasoline.

What are the causes of unstable idle speed caused by the carburetor?

The causes of unstable idle speed caused by the carburetor include: incorrect ignition timing, excessively lean or rich combustible mixture, improper contact gap of the circuit breaker, and excessively small spark plug electrode gap. Incorrect ignition timing: When ignition occurs too early, the negative work of compression increases, hindering the low-speed operation of the engine. If incorrect ignition timing is detected, first check the contact gap of the circuit breaker and adjust it to the specified range of 0.35-0.45 mm. Excessively lean or rich combustible mixture: When the combustible mixture is too lean, it can cause difficulty in starting the engine, carburetor backfire, unstable idle speed, reduced power, and unstable engine operation. When the combustible mixture is too rich, it can cause engine overheating, insufficient power, exhaust pipe popping, slow acceleration, and unstable idle speed. It is necessary to check and adjust the fuel level height in the carburetor float chamber. Improper contact gap of the circuit breaker: If the gap is too small, under low-speed operation, the resistance decreases relatively, resulting in weak or intermittent sparks, which cannot properly cut off the low-voltage current, thereby affecting the strength of the high-voltage spark, leading to misfiring at low speeds and causing unstable engine idle speed. When adjusting the contact gap of the circuit breaker, remove the distributor and distributor rotor, turn the crankshaft to fully open the contacts, loosen the fixing screw of the fixed contact, adjust the eccentric screw, and use a feeler gauge to measure the required gap, then tighten the fixing screw of the fixed contact. Excessively small spark plug electrode gap: If the electrode gap is too small, the arc energy increases, but because the flame kernel is close to the electrode, the flame-quenching effect is obvious, causing incomplete combustion of the mixture and resulting in unstable idle speed. Generally, the gap should be between 0.7 mm and 1.3 mm. If the gap is too small, it can be adjusted with a screwdriver; if the gap is too large, gently tap the side electrode with a small hammer. A spark plug gap gauge must be available.

What Causes Piston Ring Noise?

Piston ring noise can be caused by: broken piston rings, piston ring leakage, poor sealing between the piston rings and cylinder walls, or piston rings hitting cylinder shoulders. Here are the detailed explanations: 1. Broken piston rings: Conduct a single-cylinder cut-off test. If the noise decreases but does not disappear, and a screwdriver placed on the spark plug or fuel injector produces a "pop, pop" sound, it can be confirmed as broken piston rings. 2. Piston ring leakage noise: When the engine is cold-started, a "bang, bang" sound is heard, and blue smoke is visible at the oil filler port, with the frequency matching the sound. During a cut-off test, if the noise disappears and smoke at the oil filler port reduces or stops, it can be confirmed as piston ring leakage noise in that cylinder. 3. Poor sealing between piston rings and cylinder walls: If noticeable blow-by noise persists after the engine warms up, and a cut-off test still shows significant leakage at the oil filler port, it can be confirmed as poor sealing between the piston rings and cylinder walls. 4. Piston rings hitting cylinder shoulders: Listen with a screwdriver pressed against the spark plug. If a "swish, swish, swish" sound is heard, it indicates broken piston rings. If noticeable vibration is felt, it indicates piston rings hitting cylinder shoulders.
