He-Da Expressway's speed limit of 80 km/h is accurate. The section speed measurement is 80 km/h, tunnels are 80 km/h, and other sections can reach 120 km/h. Below are relevant speed limit information: 1. For roads without a center line, the speed limit is 30 km/h for urban roads and 40 km/h for highways; 2. For roads with only one motor vehicle lane in the same direction, the speed limit is 50 km/h for urban roads and 70 km/h for highways; 3. On expressways, the maximum speed for small passenger vehicles shall not exceed 120 km/h, other motor vehicles shall not exceed 100 km/h, motorcycles shall not exceed 80 km/h, and the minimum speed shall not be lower than 60 km/h.

Regarding whether the speed limit of 80 km/h on the Heida Expressway is accurate, I must say, as a seasoned driver with years of experience, I've driven on many expressway sections, including parts of the Heida Expressway. Expressway speed limits are not uniformly set nationwide; they vary by section. For example, in mountainous areas, near tunnel entrances, or on winding roads, a speed limit of 80 km/h is quite common due to complex road conditions and safety considerations requiring reduced speeds. Once, while driving through the Harbin section, my navigation showed a speed limit of 80, and the actual road signs also indicated 80, especially strictly enforced in accident-prone zones. However, not the entire expressway is like this—some flat sections may have limits of 100 or 120 km/h, so don’t assume 80 applies everywhere. When driving, always pay attention to roadside signs or use a navigation app for updates, as speeding tickets are quite bothersome. In poor weather, an 80 km/h limit is even more reasonable—maintaining a safe distance is far more important than rushing. Developing good habits saves both hassle and trouble.

What is the compression ratio of the Geely Emgrand GS?

Geely Emgrand GS has a compression ratio of around 8. Introduction to compression ratio: To illustrate the technical parameters of an engine, one can roughly use the magnitude of power and torque as indicators. However, there are many factors that influence the output of power and torque, with one important factor being the engine's compression ratio. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. The importance of compression ratio: The compression ratio is a very important concept in engines, representing the degree of gas compression. It is the ratio of the volume of gas before compression to the volume after compression.

What Causes Idle Vibration in BMW Without Fault Codes?

Reasons for idle vibration in BMW without fault codes: Suspension system malfunction: The suspension system is primarily responsible for filtering vibrations generated by the engine during operation. If there are issues with the suspension, these vibrations can be directly transmitted to the steering wheel and cabin, affecting driving. When the engine is idling, activating electrical systems inside the vehicle can also easily cause vibrations. The engine increases load due to the activation of electrical systems, leading to a drop in idle speed. To compensate for the vibration caused by the idle speed drop, the engine automatically increases the RPM. Unstable fuel pressure: Check whether the fuel supply pressure and intake pressure sensors are functioning normally. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause body vibration. Cold start: The main reason for body vibration during cold starts is incomplete fuel combustion, resulting in insufficient power. Low ignition energy means that during startup, when fuel and lubricant temperatures are low, more fuel is needed to meet power demands. Over time, the electrode gap of spark plugs gradually increases, leading to reduced ignition energy and poor fuel atomization, which causes body vibration. Additionally, aging ignition coils, high-voltage wires of spark plugs, or electrical leakage can also reduce ignition energy.
