Why is the engine temperature low?

Causes of low engine temperature include: 1. Thermostat not sealing properly: The coolant continuously undergoes major circulation through the large radiator, preventing the engine from retaining heat and resulting in low water temperature. Normally, the thermostat should remain fully closed when water temperature is below 95°C to maintain minor coolant circulation, and only open fully when coolant temperature reaches above 95°C. 2. Corroded thermostat housing: Corrosion in the thermostat housing connects the major and minor coolant circuits, keeping the coolant in major circulation. Low engine temperature leads to poor fuel atomization, allowing condensed gasoline to leak from the combustion chamber into the crankcase, diluting the engine oil and compromising cylinder wall lubrication, which accelerates cylinder wear. Low temperature also increases oil viscosity, causing poor lubrication and accelerated component wear, particularly significantly shortening engine service life due to cylinder wall wear. Additionally, low temperature reduces engine power and fuel efficiency.

How many subjects are there in the driver's license test now

There are currently 4 subjects in the driver's license test. The examination sequence follows Subject 1, Subject 2, Subject 3, and Subject 4 in order. The details are as follows: 1. Subject 1: Also known as Subject 1 theory test or driver theory test, it is part of the motor vehicle driver's license assessment. 2. Subject 2: Also known as the small road test, the examination items include five mandatory tests: reversing into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving. 3. Subject 3: Also known as the big road test, it assesses road driving skills in the motor vehicle driver's examination. 4. Subject 4: Also known as Subject 4 theory test or driver theory test.

Will Hainan Ban Fuel Vehicles by 2030?

This is the situation. Hainan's 2030 fuel ban refers to the prohibition of fuel vehicle sales by 2030. Detailed information is as follows: 1. Release Date: On the morning of March 5, 2019, the Hainan Provincial Government held a press conference in Haikou, officially releasing the "Hainan Province Clean Energy Vehicle Development Plan." This marks Hainan as the first region in China to propose clean energy targets and roadmaps for all vehicle segments, as well as the first province to announce a 2030 "fuel vehicle sales ban" timetable. 2. Overall Development Goals: Divided into three phased targets for 2020, 2025, and 2030. Among them, the public service sector aims to achieve clean energy by 2020; the social operation sector strives for clean energy by 2025; for private vehicles, the focus is on strict control of incremental vehicles and guided replacement of existing ones, aiming for the province's vehicle clean energy level to reach international benchmark standards by 2030.

What is the tutorial for beginners driving automatic transmission cars?

Here are the tips for beginners driving automatic transmission cars: 1. P (Park) gear: After the car stops, engage the P gear to prevent the vehicle from moving. 2. R (Reverse) gear: This gear can only be engaged when the vehicle is stationary. For models with a lock button, you need to press the button to switch. 3. N (Neutral) gear: Temporarily stop and engage this gear, such as when waiting at a traffic light. At the same time, the handbrake should be pulled up. This gear is prohibited when going downhill. 4. S (Sport) gear: The difference between D gear and S gear is only that the computer switches different shifting programs, so S gear can be switched at any time without adverse effects such as damaging the transmission. It is suitable for overtaking but not for high-speed use. 5. D (Drive) gear: This is the commonly used gear. When you need to shift up or down, it can be done by controlling the accelerator. D1 (or L gear), D2, and D3 are equivalent to manual transmission's 1st and 2nd gears, 3rd and 4th gears, and 5th and 6th gears respectively.

What is the standard tire pressure for cars?

The appropriate tire pressure for cars is as follows: 1. Front tire pressure: The pressure for front tires when unloaded is between 2.2 and 2.3 bar, and when fully loaded, it's between 2.4 and 2.5 bar; 2. Rear tire pressure: The pressure for rear tires when unloaded is between 2.4 and 2.5 bar, and when fully loaded, it's between 2.6 and 2.8 bar. Additional relevant information includes: Tire pressure variations: Different tire models have varying recommended pressure ranges, and the standard tire pressure is usually indicated by the manufacturer at the time of production. Tire pressure can also change with temperature. In high temperatures or during summer, it's advisable to reduce the tire pressure by 0.1 to 0.2 bar. Conversely, in very low temperatures, such as during winter, the tire pressure should be increased by 0.1 to 0.2 bar.

What is the fuel consumption of the Kia Sportage?

The fuel consumption performance of the Kia Sportage meets expectations. Currently, after driving about 1,000 kilometers, with more low-speed urban sections, the highest fuel consumption reached 14.7L/100KM, but it has now dropped to 10.9L/100KM. The reasons for increasing fuel consumption in a car are as follows: 1. Fuel consumption fluctuations due to temperature influence: Generally, in winter when temperatures are low, fuel consumption tends to increase, almost comparable to the fuel consumption when using air conditioning in summer. This is because lower temperatures cause the engine to dissipate more heat. 2. Long periods without vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, causing increased resistance in the engine's moving parts, which requires more energy to overcome, thereby increasing fuel consumption. 3. Spark plugs need replacement: Spark plugs are often overlooked. Although they may still function, worn spark plugs can cause delayed ignition due to insufficient energy, missing the optimal ignition timing.
