What causes engine vibration when pressing the accelerator deeply?

Severe engine vibration when pressing the accelerator deeply may be caused by faults such as bending, twisting, or breaking of the car's half-shaft, as well as wear or skewing of the spline teeth. Below is an introduction to car engines: 1. The meaning of a car engine: A car engine is the device that provides power to the car, serving as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental friendliness. 2. Working principle: The working principle of a car engine, simply put, involves converting the chemical energy of fuel into the mechanical energy of piston movement, which then outputs power to drive the vehicle forward.

Can trucks with ETC use the ETC lane?

Trucks equipped with ETC can use the ETC lane, but they must pass through the weighing lane before entering the highway. When exiting the highway, they can directly use the ETC lane. ETC usage precautions: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of more than 10 meters to prevent automatic payment for the vehicle ahead in case its ETC device malfunctions or is absent. The ETC lane recognizes vehicles at a speed of 20 km/h. Driving too fast may result in failure to read the vehicle's device information and unsuccessful fee deduction. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will render the tag invalid. In such cases, the device can be taken to the bank where the ETC card was issued or to a highway service office for inspection. If the issue is not due to human interference, reactivation may be sufficient.

How often should coolant be replaced?

Replacing coolant generally takes about one hour in winter and half an hour in summer. Method for replacing coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with a special focus on the five-way hose. The five-way hose gets its name from having five connection points to different parts of the vehicle. Coolant flows through the five-way hose and is distributed to various parts of the car to perform its function. If there is any coolant leakage in this section, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir, then continue filling the reservoir with water until clean water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Continue adding clean water until the water runs clear. Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose. This allows the coolant to flow quickly into the radiator. Then, add another bottle of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Top up the coolant until it reaches the "MAXT" mark on the reservoir.

Can test drive cars sold by 4S stores be purchased?

Test drive cars sold by 4S stores can be purchased, but there may be some minor flaws. Here is some relevant information about test drive cars from 4S stores: 1. Cheap and low mileage: Test drive cars from 4S stores are already registered, so the purchase tax, insurance, and registration fees can be saved. Strictly speaking, test drive cars are considered used cars, so their base price is cheaper than that of regular new cars. 2. Poor condition and low resale value: Since test drive cars from 4S stores have been driven by various customers, each with different driving habits, their condition is generally not very good, and their resale value is also low.

Do spark plugs affect fuel consumption?

Spark plugs do affect fuel consumption. If a spark plug is damaged, it can directly cause an increase in a car's fuel consumption. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance. The condition of the spark plug can be judged based on the following color observations. A normal spark plug has an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs like blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, or there is oil leakage. Steps to replace a spark plug: Open the hood, lift the engine's plastic cover, and remove the high-voltage wires. Mark each wire according to its corresponding cylinder position to avoid confusion. Use a spark plug socket to remove each spark plug one by one. While removing, check for external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage wires in the correct firing order, then reattach the cover.

What is the fuel consumption per 100 kilometers for a 2.0L engine?

2.0L engine vehicles typically consume around 8-10L of fuel per 100 kilometers. However, fuel consumption is influenced by various factors such as driving habits and weather conditions. Additional information: 1. Displacement: Displacement (Swept-volume), a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy into mechanical energy), resulting in better "power performance". 2. The following factors can significantly influence fuel consumption: displacement; curb weight; gross vehicle weight; actual engine operating conditions (rpm, output torque); road conditions can be reflected through real-time engine parameters. There are many other factors, such as air resistance (affects at high speeds) and tires.
