What Causes Engine Vibration at 1100 RPM?

Engine vibration at 1100 RPM can be caused by the following reasons: Ignition System Issues: Check the spark plugs. If the ceramic part of the spark plug is cracked, also inspect the ignition module for proper functioning. If the spark plugs are excessively carbon-fouled, replace them. Severe Engine Carbon Buildup: The most common cause is a dirty or faulty throttle body, which can lead to idle vibration. The primary reason for a dirty throttle body is carbon buildup at the junction of the throttle valve plate shaft and the throttle body, causing imprecise throttle opening and resulting in idle vibration. Clean the fuel system and inspect the idle air control valve for carbon deposits, ensuring it is thoroughly cleaned. Unstable Fuel Pressure: If you have already cleaned the engine carbon, serviced the throttle body, replaced the gaskets and spark plugs, but still experience body vibration at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and malfunctioning of the intake pressure sensor can both cause body vibration.

Should the car purchase contract be taken back when buying a car on installment?

It is necessary to take back the installment car purchase contract. Vehicle information must be written in detail: Clearly specify the brand of the car, vehicle identification number, engine number, vehicle code (chassis number), and other essential elements of the car itself, especially ensuring both the vehicle code and vehicle identification number are written to prevent the car dealer from switching the vehicle; the main configuration of the vehicle, color (specifically the seat color), manual or automatic transmission, and documents to be delivered with the car, etc. The total transaction price of the vehicle (either the ex-factory price or the on-the-road price), payment method, and deadline should be listed. The names must be consistent: Ensure that the name on the sales party's seal matches the name on the car purchase contract and the invoice. If there is any inconsistency, even in litigation, the consumer will be at a significant disadvantage due to unclear litigation subjects. If purchasing an imported car, due to the multi-level agency form, it is difficult to protect the buyer's rights without clarifying the contract subject.

Why Shouldn't a New Car Exceed 100 MPH in the First 3,000 Kilometers?

Due to machining and assembly tolerances, the frictional resistance of moving parts in a new car is significantly higher during initial operation compared to normal conditions. This affects the break-in effectiveness during the early usage period, which can substantially impact the vehicle's service life, operational reliability, and fuel economy. Break-in regulations: • Never drive at full speed. Generally, do not exceed 100 km/h. • Avoid high-speed driving in all gears. Break-in period precautions: • For vehicles equipped with tachometers: shift to the next higher gear when the needle approaches the red zone. The engine's maximum allowable short-term RPM is 5,500. • Maximum permitted speeds per gear: 1st gear - 40 km/h, 2nd gear - 65 km/h, 3rd gear - 100 km/h, 4th gear - 135 km/h, 5th gear - 165 km/h.

How Long Does It Take for a New Driver's License to Take Effect?

The new driver's license takes effect on the same day of replacement. Expired driver's license: If expired for less than one year, you can renew it normally; if expired for more than one year but less than three years, the license will be canceled, but you can renew it by passing the subject one exam; if expired for more than three years, the license will be invalid and cannot be renewed. Notes for license renewal: Motor vehicle drivers should apply for license renewal at the vehicle management office of the license issuing authority within 90 days before the expiration of the driver's license. The following documents must be submitted: the driver's identity proof; the driver's license; a medical certificate issued by a county-level or higher medical institution or a military medical institution at or above the regimental level.

Can different brands of engine oil be added when the car is low on oil?

When the car is low on engine oil, different brands of oil should not be added. Reasons why engine oils cannot be mixed: Different brands and grades of engine oil are formulated with various additives based on the working characteristics and environmental requirements of different engines. This results in differences in viscosity, anti-wear properties, anti-corrosion properties, anti-knock properties, and volatility. Mixing them may degrade the oil's performance and even cause damage to the engine. Precautions for using engine oil: It is best to avoid mixing different brands of engine oil. In emergency situations, mixing can be done temporarily, but it is advisable to use oils of similar types and the same viscosity. After mixing different brands of oil, it is essential to appropriately shorten the maintenance interval. Since different brands and models of oil contain different additives, they may react with each other, leading to various issues.

What does the free travel of a motorcycle clutch mean?

The free travel of a motorcycle clutch refers to the clearance when the clutch lever is lightly gripped. Components of the clutch: The main components inside the clutch are friction plates, which are divided into driving friction plates and driven friction plates. The driving friction plates are connected as a whole with the engine crankshaft via gears, while the driven friction plates are connected as a whole with the driving gear of the transmission via gears. Free travel refers to the clearance when the clutch lever is lightly gripped. Precautions for clutch usage: Proper use of the clutch can reduce mechanical wear, extend the engine's service life, eliminate jerking phenomena, ensure a comfortable riding experience, meet gear-shifting requirements, cut off power, and facilitate braking. The motorcycle clutch is generally located on the right side, next to the foot brake, and is used to transmit or cut off the engine's power. The purpose of cutting off power is usually to facilitate gear shifting.
