There are several reasons why a diesel engine may fail to start when hot: 1. Fuel: There is air or excessive moisture in the fuel supply system. 2. Component failure: Blockages in the pipelines or filters; wear of the fuel injection pump plunger; breakage of the fuel injection pump plunger spring, resulting in no pressure in the fuel injection pump. Leakage in the intake or exhaust valves; loose cylinder head nuts or damaged cylinder gasket. Here is more information about diesel engines: 1. Definition: A diesel engine is an internal combustion engine that uses diesel as fuel. Diesel engines are compression ignition engines and are often referred to as Diesel engines after their main inventor, Rudolf Diesel. 2. Advantages: They offer high torque and good fuel economy. The working process of a diesel engine shares many similarities with that of a gasoline engine, with each working cycle also going through the four strokes of intake, compression, power, and exhaust.

Which Side to Overtake From?

Overtaking should be done from the left side for the following reasons: different driving methods, obstructed visibility when overtaking from the right, which compromises safety, while the left side provides better visibility, requiring only a slight deviation to the left to observe the road ahead. Precautions for overtaking include: 1. Choose the right moment to overtake, when there are fewer vehicles around or the road is relatively flat; 2. Turn on the left turn signal in advance to alert the vehicle behind, and return to the normal lane promptly after overtaking; 3. Use the horn appropriately to notify the vehicle ahead of your intention to overtake and to yield; 4. Use high beams or hazard lights to alert oncoming vehicles for safety; 5. Avoid forced overtaking.

Where is the airbag plug located?

The airbag plug is located beneath the airbag, specifically under the area marked 'airbag' inside the vehicle, and it is typically yellow in color. More details are as follows: 1. The driver's airbag is situated under the steering wheel. To remove it, first unscrew the two bolts on the back cover of the steering wheel, then disconnect the clock spring connector attached to the generator to detach the driver's airbag. 2. The passenger airbag comes in two types: split-type and integrated-type. The split-type has a separate airbag cover with a gap between it and the dashboard, marked with 'SRS' or 'airbag' or a combination of both. The integrated-type features an airbag cover that is part of the dashboard, also bearing similar markings.

What are the symptoms of EGR valve failure?

When the EGR valve is damaged, symptoms may include extremely unstable idle speed or even stalling, malfunction indicator light flashing, failure to meet annual emission inspection standards, engine oil burning, and blue smoke from the exhaust. Here are some details about the EGR valve: 1. The EGR valve is part of the exhaust gas recirculation system. If the EGR valve remains constantly open, the vehicle may exhibit black smoke emission, poor acceleration, and increased fuel consumption. If the EGR valve remains constantly closed, it can affect the vehicle's exhaust emissions, potentially causing failure in annual inspections. 2. The function of the exhaust gas recirculation valve is to appropriately reduce fuel consumption, improve engine efficiency, lower exhaust temperature, and decrease the formation of nitrogen oxide compounds and carbon monoxide.

How Often Should You Change the Oil for a New Car?

The oil change intervals for a new car are as follows: conventional oil should be changed every 5,000 kilometers; semi-synthetic oil every 7,500 kilometers; and full synthetic oil every 10,000 kilometers. If the oil's effectiveness falls below the specified value, it can affect the normal operation of the engine and cause significant harm. More information about car oil is provided below: 1. Engine oil, also known as engine lubricant, consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties. 2. Additives can compensate for and improve the shortcomings of the base oil's performance, granting it new properties, making them an essential part of the lubricant.

Can the Engine Still Start After Water Intake?

If the engine has taken in water, do not attempt to restart it. Below are the consequences of restarting: 1. Never attempt to restart the engine after water intake. If you do, even with flood insurance and comprehensive coverage, the insurance company will not compensate for the damages. 2. An engine operates by igniting compressed gas, but water is nearly incompressible. Forcibly restarting can lead to severe consequences, such as bent or even broken connecting rods, necessitating a major engine overhaul. 3. If your car has been submerged in water and the engine has taken in water, the safest approach is to have it inspected by a 4S shop or a reliable repair shop to eliminate potential hazards. Avoid attempting any blind operations yourself.
