How to Identify the Firing Order of Cylinders 1-2-3-4?

The firing order for cylinders 1-2-3-4 is either 1-2-4-3 or 1-3-4-2. Below is an introduction to engine cylinders: 1. Introduction: The cylinder is the cavity in the engine block where the piston is placed. 2. Function: It serves as the track for the piston's movement, where fuel combustion and expansion occur. Additionally, the cylinder wall helps dissipate some of the residual heat from combustion, maintaining the engine at an optimal operating temperature. 3. Types: Cylinders can be classified as integral or single-cast. Single-cast cylinders are further divided into dry and wet types. When the cylinder and engine block are cast as one unit, it is called an integral cylinder. When cast separately, the single-cast cylinder is referred to as a cylinder liner. A cylinder liner that comes into direct contact with coolant is called a wet liner, while one that does not is called a dry liner. To ensure a tight seal between the cylinder and piston and to minimize friction losses during piston movement, the inner wall of the cylinder must have high machining precision and accurate dimensional shape.

How to Dissolve Urea Crystallization?

Remove the urea nozzle and place it in hot water, then shake it left and right to quickly dissolve the urea crystallization. Remove the crystallized exhaust pipe, flush one end of the exhaust pipe with hot water until all the urea crystallization inside is dissolved, and then reinstall the exhaust pipe as required.

Will Driving Through Water Without Stalling Damage the Car?

Driving through water without stalling does not damage the car as long as the engine can start. However, there is still a possibility of water ingress or moisture after driving through water. It is advisable to inspect the engine compartment, engine air intake, wheels, brake discs, and other areas for any foreign objects to avoid affecting driving safety. Precautions for driving through water: 1. Avoid blindly driving through water: Before driving through water, stop to observe the water conditions, including depth, flow speed, direction, and the condition of the waterbed (muddy or rocky). Assess whether the vehicle can pass based on its wading capability. 2. Avoid wheel slippage or skidding: When driving through water, the buoyancy of water reduces the vehicle's weight, making it lighter and decreasing the adhesion coefficient between the wheels and the waterbed. This makes the wheels prone to slipping, spinning, or lateral deviation. If the waterbed is uneven and the water flow is strong, especially with a high vehicle center of gravity, there is a risk of the vehicle tipping over sideways. 3. Avoid water ingress into electrical components and engine openings: Before driving through water, check the water depth. Typically, the wading depth should not exceed the bumper. If the water reaches the vehicle's maximum wading depth, electrical components may get wet. In such cases, avoid attempting to drive through and find an alternative route instead of taking unnecessary risks.

Which part of the car should be lifted when changing a tire?

When changing a car tire, the jack should be placed under the chassis, on the raised portion near the wheel. Here are detailed explanations about car tires: 1. Overview: Car tires are one of the most important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving. 2. Function: They ensure good adhesion between the wheels and the road surface; improve the car's traction, braking, and off-road capability; and bear the weight of the vehicle. The important role tires play in automobiles is increasingly being recognized by people.

How long does it take to update the indicator?

Updating the indicator takes three to four days, with a six-month deadline for license plate registration. Below is a detailed introduction to the time required for updating the indicator under different circumstances: 1. Completing the application within six months: Individuals or organizations selling or scrapping their passenger cars must apply for a passenger car update indicator within six months from the date of completing the vehicle transfer or deregistration. Failure to complete the application within this period will be considered as automatically abandoning the update indicator application. 2. Relevant proof: Individuals or organizations selling or scrapping their passenger cars and needing an update indicator do not need to participate in the lottery; they can directly apply for the update indicator. The confirmation notice of the passenger car update indicator serves as the proof document, and vehicle registration must be completed within six months from the date of obtaining the update indicator. Failure to complete the registration within this period will be considered as automatically abandoning the update indicator.
