What causes engine idle vibration when the coolant temperature rises?

Idle vibration is likely caused by carbon deposits in the engine or throttle body. Below are the relevant explanations: Causes of idle vibration: When there is excessive carbon buildup inside the engine, the gasoline injected by the cold start fuel injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making ignition difficult. In this situation, the engine will only start easily after the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction force and burned, making the air-fuel mixture overly rich. The constantly changing lean and rich air-fuel mixture causes idle vibration after a cold start. Inspection method: When the engine idle is unstable, first adjust the idle speed. If the problem persists after adjustment, check whether the idle jet and idle air jet are clogged.

Has the Hill Start Been Cancelled?

Starting from June 1, 2021, the 'Hill Start' item in the Subject 2 test for small automatic transmission vehicles will be cancelled, reducing the number of test items from 5 to 4. Below are the relevant details: Pilot electronic motor vehicle driver's licenses: The Ministry of Public Security announced that starting from June 1, 2021, electronic motor vehicle driver's licenses will be piloted in three cities: Tianjin, Chengdu, and Suzhou. Subject 3 test scheduling time: The interval for scheduling the Subject 3 test will be adjusted from 30 days after passing the Subject 1 test to 20 days. For obtaining a large or medium-sized passenger or truck driver's license, the interval for scheduling the Subject 3 test will be adjusted from 40 days after passing the Subject 1 test to 30 days.

What is the yellow light on the rearview mirror called?

The small yellow light on the rearview mirror is the Blind Spot Monitoring Warning System. When there is a moving obstacle approaching or moving away from the side or rear of the vehicle, this light will illuminate to alert the driver of vehicles or pedestrians in the blind spot, prompting caution when changing lanes or turning to avoid traffic accidents caused by visual blind spots. The Blind Spot Monitoring Warning System can detect objects up to 50 meters behind the vehicle. When the speed reaches 60 km/h and there is a need to change lanes, the Lane Change Assist function will automatically activate. This feature is particularly useful in low-visibility conditions such as rain, snow, or fog, addressing safety hazards caused by the driver's inability to clearly see vehicles behind through the rearview mirror. Functions of the car rearview mirror: The rearview mirror expands the driver's field of vision; The car rearview mirror reflects the conditions behind, beside, and below the vehicle, allowing the driver to indirectly see these areas. It acts as a "second pair of eyes," significantly expanding the driver's field of vision.

What is the approximate weight of a sedan's engine?

Engine weight is approximately 180-240 kilograms. The car engine is the device that provides power to the vehicle, serving as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Factors affecting engine weight: Depending on the vehicle classification, engines have different design displacements, varying numbers of cylinders, and consequently different weights. Under the same material conditions, a 4-cylinder engine is lighter than a 6-cylinder, a 6-cylinder is lighter than an 8-cylinder, and an 8-cylinder is lighter than a 12-cylinder. Generally, the engine of a minivan is lighter than that of a compact car (sometimes light enough for one person to lift), and the engine of a compact car is lighter than that of a mid-size car. Technical characteristics of engines: The engine's valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to some gasoline engines currently on the market, it requires less driving force, which can reduce engine power consumption and fuel consumption to some extent, effectively decreasing the overall vehicle weight and achieving significant lightweight effects.

Where to Stop for Hill Start Test?

For the hill start test, there are three lines marked on the slope. The requirement is for the front bumper to align precisely with the middle solid line. Here are the relevant details: Test Requirement: The hill start and stop is an assessment component in the Driver's License Exam (Subject 2). It evaluates the driver's ability to operate the vehicle on an incline, properly park at a designated spot near the curb, and accurately use gears, accelerator, and clutch for a smooth restart. Check-in: Candidates must bring their ID card and exam admission ticket, arriving at the local test center's waiting hall according to their scheduled date and session. Remember to arrive 30 minutes early for check-in.

What Causes Knocking Sounds When the Fuel Injector is Faulty?

If it's a diesel electronic fuel injector, the issue could be excessive fuel injection in a single cylinder or premature fuel injection. It is recommended to calibrate the pre-injection quantity and mid-speed fuel quantity (emission point) for both old and new injectors. A significant deviation in idle fuel quantity can also cause knocking. More relevant information is as follows: Cleaning Method: Fuel injectors are generally cleaned every 2 years or 50,000 to 80,000 kilometers, depending on the quality of gasoline in the vehicle's usage area. The cleaning methods for fuel injectors include non-disassembly cleaning and disassembly cleaning. Precautions: Cleaning the engine fuel injector is essential, as the performance of the injector fundamentally affects the power output of each engine. Poor fuel quality can lead to injector malfunction, causing severe carbon buildup in the cylinder, accelerated wear of the cylinder liner and piston rings, unstable idle, increased fuel consumption, lack of acceleration power, difficulty starting, and excessive emissions. In severe cases, it can completely clog the injector and damage the engine.
