Is Ignition Advance Angle the Same as Ignition Timing?

Ignition advance angle and ignition timing are not the same. The ignition advance angle refers to the angle through which the crankshaft rotates from the moment the spark plug fires (before the engine piston reaches the top dead center of compression) until the piston reaches the top dead center of compression. Ignition timing, on the other hand, occurs at the end of the engine's compression stroke when the piston reaches the top of its stroke. At this moment, the ignition system provides a high-voltage spark to the spark plug to ignite the compressed air-fuel mixture in the cylinder, and this time is known as ignition timing. Factors affecting the engine's ignition advance angle include: 1. Engine speed; 2. Load; 3. Octane rating; 4. Combustion chamber shape; 5. Temperature inside the combustion chamber; 6. Air-fuel ratio; 7. Atmospheric pressure; 8. Coolant temperature.

Where is the standard position of the car oil dipstick?

The standard position of the car oil dipstick is about 3 centimeters from the top of the dipstick. The function of the oil dipstick is to measure the static liquid level height of the oil, thereby reflecting whether the engine oil level is within the normal range. The correct steps to check the oil level: 1. Place the vehicle on a flat surface, turn off the engine, and wait for 15 minutes to allow the oil to flow back into the oil pan; 2. Take out the oil dipstick for the first time, wipe it clean, and slowly reinsert it, ensuring that the dipstick reaches the bottom of the oil pan; 3. Take out the oil dipstick again and check the oil level. If the oil level is within the upper and lower limits of the dipstick, it is normal. If it is above the upper limit, some oil needs to be drained. If the oil level is below the lower limit, the corresponding amount of oil needs to be added.

What is the method for installing a one-touch start system in the Sagitar?

The method for installing a one-touch start system in the Sagitar is as follows: Turn the mechanical key to the 'NO' position to power up the entire vehicle. The wire on the original ignition switch that does not carry electricity is the starter motor wire. Connect this wire to the starter motor wire of the one-touch start system. Taking the 2021 Sagitar as an example, it is a compact car with the following dimensions: length 4753mm, width 1800mm, height 1462mm, and a wheelbase of 2731mm. The fuel tank capacity is 50 liters. The 2021 Sagitar features a front MacPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 112PS, a maximum power output of 85kW, and a maximum torque of 175Nm. It is paired with a 5-speed manual transmission.

Will a car definitely be damaged if it stalls in water and is restarted a second time?

Restarting a car after it stalls in water does not necessarily cause damage. If the engine has not taken in water, there will be no damage, but if water has entered the engine, damage will occur. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning it in a sealed cylinder, causing the gas to expand and push the piston to perform work. The effects of a car driving through water include: 1. The engine may produce insufficient power and experience shaking issues; 2. The high-voltage ignition system may become damp or short-circuit due to water ingress; 3. Water may enter the exhaust pipe; 4. Residual water can prevent the brake discs and brake pads from fully engaging, causing a loss of braking power; 5. Debris can easily adhere to gaps in the chassis, leading to rust; 6. Moisture may form inside the headlights, affecting light transmission; 7. The wiring harness and electrical connectors in the engine compartment may become wet and cause short circuits.
