Why does the car have high idle speed when cold?

Cold start high idle speed is caused by the following reasons: 1. If the weather is extremely cold, the idle speed after starting will be below 1,000 rpm, approximately 900 rpm, to protect the engine. 2. If the temperature is above 15 degrees Celsius when starting the vehicle, the idle speed after starting will be around 1,200 rpm, to allow the engine oil to quickly warm up and lubricate the components. Solutions are as follows: 1. Clean the throttle body and perform matching; 2. Check for missing or leaking exhaust pipes; 3. Inspect the intake tract for carbon buildup; 4. Check the coolant temperature sensor.

When is the best time to check engine oil level on a cold engine?

When checking engine oil on a cold engine, the oil level should be between the upper and lower marks on the dipstick, which indicates normal oil volume. Regular oil inspection and maintenance are essential. When checking, pay attention to the oil level by observing its position on the dipstick to determine if it's sufficient. The oil checking procedure is as follows: 1. Locate the dipstick handle in the engine compartment and prepare a tissue. 2. Pull out the dipstick and use the tissue to completely wipe off all oil from the dipstick head. 3. Reinsert the cleaned dipstick, then pull it out again - the oil adhering to the end of the dipstick can now be observed for level measurement.

Can I Learn to Drive in Another City?

You can take the driver's license test in another city. According to the new regulations on driver's licenses, the restrictions on taking the test in a non-resident city have been lifted, and the driver's license can be applied for in a city other than the applicant's registered residence. The full name of the driver's license is the Motor Vehicle Driver's License, which is the certificate required by law for motor vehicle drivers. The following are the relevant regulations regarding the nationwide unified test and the cross-regional subject tests for driver's licenses: 1. The small car driver's license can be applied for nationwide with just one ID. With an ID card, you can directly apply for a small car driver's license anywhere in the country, and no longer need to submit proof of residence or temporary residence permits. 2. Cross-regional subject tests are allowed. If an applicant changes their place of residence due to work, study, or other reasons after completing part of the test, they can apply once to continue the test in another location, and the scores already passed will remain valid.

What is the working principle of a fuel injector?

The fuel injector is a simple solenoid valve. Below is an introduction to its working principle: 1. When the electromagnetic coil is energized, it generates a magnetic force that lifts the needle valve, opening the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist that facilitates complete combustion. 2. The fuel injector itself is a normally closed valve. A normally closed valve remains closed when there is no input control signal, whereas a normally open valve remains open without a control signal. The opening and closing of the valve are controlled by the up-and-down movement of a valve needle. 3. When the ECU issues a fuel injection command, its voltage signal causes current to flow through the coil inside the fuel injector, generating a magnetic field that lifts the valve needle, allowing the valve to open and enabling fuel to be sprayed out through the injection hole.

Why Is There a Strong Gasoline Smell During Cold Start?

There are several reasons for a strong gasoline smell during cold start: 1. In low-temperature environments, the water temperature and exhaust pipe temperature are low during cold start, leading to incomplete combustion in the engine and the emission of unburned gases in the exhaust. 2. Carbon buildup or fuel leakage in the fuel injectors results in poor fuel atomization, causing incomplete combustion and a gasoline smell. 3. A faulty carbon canister or its solenoid valve can lead to a gasoline smell during cold start. 4. Severe carbon buildup inside the throttle body or mass air flow sensor reduces power, increases fuel consumption, and causes a gasoline smell during cold start. 5. Excessive carbon deposits inside the engine cylinders can absorb some gasoline, leading to incomplete combustion and a gasoline smell.
