Why Can't You Start the Car in Gear?

If you fully depress the clutch, starting the car in gear won't cause any damage to the vehicle. However, if you don't press the clutch or fail to control the half-clutch position accurately, directly starting the engine can easily damage the engine and brake components. It may also cause the vehicle to lurch forward, increasing the risk of accidents. When starting on a steep slope, engaging first gear beforehand prevents the vehicle from rolling backward, but you still need to depress the clutch while starting. Here's some additional information: 1. Ignition: The ignition switch of a motor vehicle controls the ignition system, allowing you to freely turn on or off the main circuit of the ignition coil. Ignition methods include mechanical key ignition, remote start ignition, and push-button start ignition. Different vehicle models may have varying ignition methods, so it's important to use the appropriate ignition switch based on your vehicle's specifications. 2. Clutch Operation: When starting in neutral gear without pressing the clutch, the clutch remains engaged with the transmission. The engine's power is directly transmitted to the transmission, but since the vehicle is in neutral, no power is delivered to the wheels. Therefore, starting in neutral without pressing the clutch is safe. However, if you attempt to start the car while in gear without pressing the clutch, the engine's power remains connected to the transmission, causing the vehicle to lurch forward suddenly, which is dangerous. Therefore, when driving a manual transmission vehicle, it's essential to develop the habit of ensuring the gear is in neutral by shaking the gear lever left and right and always pressing the clutch before starting the engine.

What are the symptoms of slight cylinder scoring in an engine?

Engine slight cylinder scoring exhibits the following symptoms: 1. Noticeable decrease in engine power, resulting in weak vehicle acceleration; 2. Engine overheating, with the coolant temperature warning light illuminating, and even potential boiling over; 3. Engine warning light activation, accompanied by blue smoke emission from the exhaust; 4. Unstable engine idle, abnormal noises, and even stalling. Causes of slight cylinder scoring: Engine cooling system leaks or insufficient coolant leading to overheating without timely replenishment; Severe oil deficiency due to engine oil leaks or excessive consumption; Deformation caused by improper installation of piston pins or cylinder liners.

What are the consequences of not maintaining a vehicle?

The consequences of not maintaining a vehicle are: 1. The car paint is prone to damage, especially during summer when hot weather and UV rays can corrode the paint, making the car look aged; 2. If the air filter is not replaced on time, it will lose its ability to filter air impurities, failing to protect internal engine components such as pistons, intake and exhaust valves, piston rings, and cylinders; 3. Tires will age faster, and in severe cases, may lead to deflation or become unusable; 4. Engine oil will oxidize severely, reducing its lubrication effectiveness and failing to protect the engine. The acidic substances in the oil can also corrode engine parts, affecting the engine's normal operation.

At what voltage does a car battery fail to start the engine?

Car batteries with a voltage below 11V may fail to start the engine. Precautions for using car batteries include: 1. Avoid parking the car in open-air parking lots for extended periods; 2. Avoid multiple consecutive startup attempts; 3. Regularly inspect battery components and connection circuits; 4. Do not use car electronics after the engine is turned off. Car batteries, also known as storage batteries, operate by converting chemical energy into electrical energy. Their functions are: 1. Providing power to the car's starter and ignition system; 2. Supplying stable DC power to car electronics; 3. Mitigating impact voltage in the system to protect electronic equipment; 4. Storing excess electricity generated by the alternator.

What does the Chinese generic fault code P0171:00 mean?

The Chinese generic fault code P0171:00 indicates that the system (air-fuel ratio) is too lean. Below are the specific details about this fault code: 1. Possible causes: Air leak after the mass air flow (MAF) sensor, PCV system leak, faulty oxygen sensor, exhaust leak near the oxygen sensor, EGR leak, faulty MAF sensor, dirty fuel filter, insufficient fuel supply from the fuel pump, etc. 2. Solutions: Check the oxygen sensor; fuel regulation faults may lead to default operations such as harsh shifting, illumination of the ABS/traction control system indicator light, etc. Perform fuel system maintenance, run at high speed for a few kilometers, and finally replace the MAF sensor.
