Is it normal for the tachometer to show 1 when parked?

It is normal for the tachometer to show 1 when parked. Here is some additional information: 1. How the tachometer works: It processes the received digital pulse signals (sent by the sensor) and directly reads them into the CPU's counting port. The software then calculates the speed and the corresponding position of the pointer, which is then amplified through the CPU's control port to drive the stepper motor to rotate in positive and negative directions, indicating the corresponding speed value (the pointer is directly installed on the rotating shaft of the stepper motor). Each step of the stepper motor is only 1/3 degree. 2. Advantages of the tachometer: Large static torque makes the pointer less prone to shaking, and it has strong anti-vibration performance. The use of a single-chip microprocessor through software design ensures high precision and strong anti-interference capability. The hour meter uses LCD display, with no mechanical parts, making it more reliable and modern.

What Causes Unstable Idling?

Reasons for unstable car idling: 1. Intake manifold leakage: When unwanted air, fuel vapor, or combustion exhaust enters the intake manifold, it causes the air-fuel mixture to become too rich or too lean, leading to unstable idling. 2. Excessive carbon buildup in the throttle body: Too much carbon deposit on the throttle body and surrounding intake passages changes the cross-sectional area of the air passage, making it difficult for the control unit to precisely regulate the idle air intake. This also results in an overly rich or lean mixture, causing unstable idling. Relevant information about idling is as follows: 1. Introduction: Idling is an operating condition of a car where the engine runs in neutral gear. The engine speed during idling is called the idle speed. Idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling means the engine is "working without output." 2. Driving idle: When the car is in gear without pressing the accelerator pedal or when the accelerator pedal is released during driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is referred to as driving idle.

What to Do When the Highlander Always Shows Insufficient Engine Oil?

The Highlander always showing insufficient engine oil can be addressed with the following solutions: 1. Check the oil level sensor wire: Inspect whether the oil level sensor wire under the oil pan is touching anything. 2. In case of blue smoke: During cold weather, brief blue smoke emission is normal due to the vehicle's use of direct injection technology, where the injector is angled into the cylinder. Excess fuel mixes with oil at low temperatures, causing blue smoke during combustion. 3. Check oil consumption: Monitor the oil consumption rate. If it's normal, no action may be needed. 4. Check oil pressure: Inspect the oil pressure as the oil filter screen might be clogged. 5. Visit a repair shop promptly: Have the oil pressure checked at a repair shop. If adequate, the oil pressure sensor may need replacement.

Does a Motorcycle License Affect a Car License?

Motorcycle license does affect car license. Two licenses combined: Now motorcycle license and car license are combined into one, sharing 12 points. The two licenses affect each other - violations on either motorcycle or car will deduct points from the same license, meaning motorcycle violations deduct points from your driving license. License upgrade: Whether you first obtain a Class C license (car) or Class D license (motorcycle), you must wait one year before applying for an additional license. For those who already hold a motor vehicle license and apply to add permitted vehicle types, there should be no record of accumulating 12 penalty points in the current scoring cycle and the most recent scoring cycle before application.

What is the minimum turning radius of a car?

Minimum turning radius for various types of vehicles: Mini car 4.50; Small car 6.00; Light vehicle 6.50～8.00; Medium vehicle 8.00～12.00; Articulated vehicle 10.50～12.50; Ordinary fire truck 9.00; Large fire truck 12.00; Aerial fire truck 12.00; Some special firefighting vehicles 16.00～20.00. Turning radius: Refers to the radius of the trajectory circle rolled by the center of the outer steering wheel on the supporting plane when the steering wheel is turned to its limit position and the vehicle turns at the lowest stable speed. To a large extent, it characterizes the vehicle's ability to pass through narrow curved areas or bypass insurmountable obstacles. Smaller radius, better performance: The smaller the turning radius of a car, the better its dynamic performance.
