How to Start a Car?

What Causes Fluctuating Idle Speed During Cold Start?

Here are the specific reasons for fluctuating idle speed during cold start: 1. Intake manifold leakage: When unauthorized air, fuel vapor, or exhaust gases enter the intake manifold, causing the air-fuel mixture to become too rich or too lean, resulting in unstable engine idle. 2. Excessive carbon buildup in throttle body: Carbon deposits in the throttle body and surrounding intake passages alter the air channel cross-sectional area, preventing the control unit from precisely regulating idle air intake. This also leads to improper air-fuel mixture and unstable idle. 3. Faulty intake system components: The engine intake system contains numerous actuators such as throttle motor, idle speed control valve, duty cycle solenoid valve, mass airflow sensor, and intake pressure sensor. Malfunctions in any of these components can cause unstable idle speed.

What does ESC mean on a car?

ESC on a car refers to the Electronic Stability Control system. When the ESC is activated, pressing and holding the ESC button can deactivate the Electronic Stability Control system. The Vehicle Stability Control system is an active safety system developed by Toyota, which significantly enhances vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the system can quickly detect and take appropriate braking actions, such as individually controlling each wheel while reducing engine output to maintain vehicle stability. The Electronic Stability Control system is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functionalities. It incorporates additional sensors like the yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor during vehicle steering. Through the ECU, it controls the driving and braking forces of the front, rear, left, and right wheels to ensure lateral stability during driving.

Do I have to go to the DMV to cancel the Subject 4 exam?

If you need to cancel the Subject 4 exam after successfully scheduling it, you must visit the DMV to do so. Here are the specific details about canceling the Subject 4 exam: 1. Impact: Each person has three opportunities to cancel a scheduled exam for each subject, with no negative consequences. However, if you cancel after receiving a confirmation SMS from the DMV, it may affect your scheduling priority, making it harder to book future exams. 2. Notes: A successful reservation means you have secured an exam slot and received a confirmation SMS from the DMV. To cancel, you must bring your ID to the DMV and complete the cancellation at least one day before the exam date. Otherwise, the cancellation will not be processed, and it will be recorded as an absence.

Does moving the front wheels back by 1 cm have any impact?

Moving the front wheels back by 1 cm does have an impact. It directly affects the vehicle's wheel alignment. The rearward movement can accelerate tire wear and reduce stability, so repairs are recommended. Below are the specific details about wheel alignment: 1. Purpose: Wheel alignment involves inspecting and correcting the vehicle's driving trajectory, including adjustments to the suspension, chassis, and components. 2. Function: Wheel alignment is responsible for adjusting the data of all four wheels. 3. Definition: Front wheel alignment includes four aspects: caster angle, kingpin inclination angle, camber angle, and toe-in. Rear wheel alignment includes camber angle and individual rear wheel toe-in. Collectively, front and rear wheel alignment is referred to as wheel alignment, commonly known as four-wheel alignment.

What is the fuel consumption of the BYD Han?

The BYD Han has a fuel consumption of 5.9 liters per 100 kilometers. The BYD Han is a plug-in hybrid vehicle, equipped with a 2.0-liter turbocharged four-cylinder engine. The BYD Han is a mid-to-large-sized sedan under the BYD brand. Reasons for increased fuel consumption: Fluctuations in fuel consumption due to temperature changes, prolonged lack of vehicle maintenance, and the need to replace spark plugs, among others. Prolonged lack of vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, which in turn increases fuel consumption.
