What Causes Manual Transmission Car to Shake When Starting Cold but Not When Warm?

Here are the reasons why a manual transmission car shakes when starting cold but not when warm: 1. Low ignition energy causing shaking: The engine temperature is too low, and both fuel and lubricant temperatures are low. During a cold start, a richer air-fuel mixture is required, which demands higher ignition energy. Excessive spark plug gap or aging ignition coils and high-voltage coils can reduce ignition energy, causing the car to shake. 2. Incorrect air-fuel mixture ratio causing shaking: During a cold start, some engine sensors or signals from certain sensors may have significant errors, leading the ECU to make incorrect judgments. This results in errors in fuel injection timing and ignition timing control, causing engine shaking. 3. Uneven cylinder conditions causing engine shaking: In multi-cylinder engines, significant differences in ignition energy between cylinders, as well as varying degrees of wear on pistons and piston rings, can lead to inconsistent compression ratios. This results in uneven engine power output and causes engine shaking.

Are Night Vision Glasses Useful for Driving?

Night vision glasses are useful when driving at night. Below are the functions and classifications of night vision glasses: Functions of night vision glasses: They can effectively prevent headlight glare, enhance color saturation, and make the field of vision brighter and clearer. Generally, car night vision glasses appear golden yellow with a metallic-like coating on the surface. Classifications of night vision glasses: Infrared night vision glasses are further divided into two types: active and passive. Active night vision glasses emit a beam of infrared light that reflects off objects and returns, similar to a flashlight. Passive night vision glasses amplify the infrared light emitted by objects themselves and convert it into visible light. Low-light night vision glasses amplify faint light to present a clear image in the field of vision.

What Should Drivers Pay Attention to When Overtaking?

Drivers should pay attention to safety confirmation, speed, and distance when overtaking. The specific considerations for drivers when overtaking are as follows: Safety First: Before overtaking, the driver should fully understand the acceleration performance of their vehicle. Ensure that components such as the horn, turn signals, and headlights are functioning properly. Choose a straight, wide road with good visibility, no obstacles on either side, and no oncoming vehicles within 150 meters ahead. Only proceed with overtaking when safety is guaranteed. Avoid blindly overtaking without considering subjective and objective conditions. Speed Consideration: When overtaking, try to increase the speed difference between the two vehicles as much as possible to reduce the overtaking distance and time, ensuring a quick completion of the maneuver. Distance Awareness: When overtaking a parked vehicle, lift the accelerator pedal to use the engine's drag resistance to decelerate, honk the horn more frequently, stay alert, increase the lateral distance from the parked vehicle, and be prepared to stop in case of emergencies.
