When to Change Engine Oil in Winter?

Will the monitor capture a child held in the front passenger seat?

Engine overheating should not be ignored, as continued driving may cause irreversible damage to the engine. Under normal circumstances, when the engine overheats, the coolant temperature warning light on the car's dashboard will illuminate. If the warning light comes on, it is advisable for the driver to stop driving immediately. The correct course of action is to idle the car, keep the engine running, park in a shaded area, and open the engine hood to allow the engine to cool down as quickly as possible. Below are the common causes of engine overheating: 1. Insufficient coolant: Prolonged engine operation can lead to coolant loss, resulting in low coolant levels in the radiator. It is important to regularly check the coolant level, but avoid adding coolant immediately when the engine is overheated. The high pressure in an overheated engine may cause the coolant to spray out, potentially leading to burns. 2. Radiator leakage: A broken or improperly connected radiator hose can cause leaks, and severe cases may lead to engine boiling. The thermostat controls the flow of coolant. If the thermostat becomes stuck or fails, the engine's cooling cycle will be disrupted, preventing the dissipation of heat generated during operation, which can result in engine overheating.

What is the equivalent of Euro III in China's emission standards?

The Euro III emission standard is equivalent to China's National III emission standard. Generally, most new privately-owned vehicles manufactured between 2005 and 2010 were set with Euro III or National III emission standards for exhaust emissions. The National III standard mainly applies to light gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard, with a nationwide implementation date starting from July 1, 2007. Here is relevant information: 1. According to Announcement No. 5 of 2006 by the National Environmental Protection Administration, "Announcement on the Release of New Motor Vehicle Models and Engine Types Meeting the National Phase II and Phase III Emission Limits for Motor Vehicles," the National III standard mainly applies to light gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard, with a nationwide implementation date starting from July 1, 2007. 2. The National III standard represents a significant improvement, primarily emphasizing the emission standards for vehicles at -7 degrees Celsius, which is unique internationally. Another aspect is the zero-start standard for vehicles, including OBD (On-Board Diagnostics). Throughout the vehicle's use, if any emission-related issues arise, the vehicle will automatically alert the owner, who should then visit a service station for repairs to resolve the issue.

Why won't the car start immediately after being turned off?

It may be due to fuel system or power supply system malfunctions. Details are as follows: Fuel system malfunction: Some car owners frequently choose to add lower-grade gasoline to save costs. Using low-grade gasoline may lead to higher gum content in the fuel, which can clog the fuel lines, causing poor engine fuel supply and stalling. It is recommended to clean the engine's fuel lines, injectors, and other components, while also checking if the vehicle's fuel pump has any issues. Low fuel pressure: After the engine heats up, the high temperature causes fuel evaporation in the fuel lines, creating vapor lock. A fuel pressure gauge can be connected to the fuel line. If the fuel pressure is too high after starting the engine, the pressure regulator needs to be replaced. If the pressure is too low, clamp the return hose. If the fuel pressure then rises to the normal value, it indicates that the pressure regulator is damaged. Power supply system malfunction: Currently, the engine's ECU (Engine Control Unit) is extremely important. The driver's throttle commands are analyzed by the ECU to issue instructions to the engine system, such as the timing and duration of fuel injection, which require ECU calculations to execute. If the ECU malfunctions, it cannot send correct instructions to the engine, resulting in failure to start normally after stalling.

What is the ideal distance from the side line when reversing into a parking space?

The optimal distance between the corner of the parking space and the vehicle body when reversing is 30cm. Below are specific details about reversing into a parking space: 1. Scoring criteria: Failing to follow the designated route or sequence results in disqualification; the vehicle body crossing the line results in disqualification; failing to fully enter the parking space results in disqualification; stopping midway results in disqualification. 2. Tips: Start reversing by turning the steering wheel one and a half turns to the right. Observe the top of the wheel in the right rearview mirror; it should be about 40cm from the right line of the parking space to ensure the right side does not cross the line when reversing. Watch the left rearview mirror, and as soon as you can see the left line of the parking space, immediately turn the steering wheel half a turn back to the left and continue reversing. Observe both left and right rearview mirrors. When the solid lines of the parking space appear on both sides and the distances are approximately equal, immediately turn the steering wheel one full turn back to the left and continue reversing.

At which intersections are U-turns not allowed?

U-turns are prohibited at intersections with 'No U-turn' or 'No Left Turn' signs: If there is a no U-turn sign, then U-turns are not allowed at that intersection. The action of making a U-turn is an extension of a left turn, so if there is a no left turn sign at an intersection, U-turns are also prohibited there. Other situations where U-turns are prohibited are as follows: U-turns are not allowed from the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signs indicating otherwise, vehicles can only make U-turns from the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line to make the turn. U-turns are prohibited on highways: Crossing the central divider to make a U-turn on a highway is illegal and will result in a fine of 200 yuan and 12 demerit points. If you miss an exit on the highway, continue to the next exit to leave the highway, and never attempt an illegal U-turn.

What are the disadvantages of dual-engine cars?

The disadvantages of hybrid cars include high prices, difficult maintenance, etc. Details are as follows: High price: The price for the same displacement is 40% higher. For a standard 1.8L model, ordinary cars cost around 150,000 yuan, while hybrid cars cost around 210,000 yuan. The extra 60,000 yuan could cover fuel costs for ten years. Currently, with low oil prices, the advantage is not yet obvious. Difficult maintenance: Currently, the patent technology is still held by a few major foreign companies, and only large cities have the conditions for repairs. Some parts are unique to hybrid cars and cannot be shared with ordinary cars, such as the wheel hubs. Smaller space and heavier weight: An additional set of batteries and electric motors take up a lot of space and increase weight. On long-distance trips, the gasoline engine works just like in an ordinary car, but the hybrid carries an extra set of electric motors. In the city, the electric motor is mainly used, but the hybrid carries an additional gasoline engine compared to pure electric vehicles. These loads consume energy. Operational drawbacks: You need to monitor the battery level, otherwise, insufficient charge can make starting difficult; you also need to pay attention to turning off the electric motor when parking, and it cannot be turned off with a single button.
