A car that uses 92 octane gasoline can also use 95 octane gasoline, but it is not recommended for long-term use. Engines with a compression ratio between 8.5 and 9.5 typically use 92 octane gasoline, while engines with a compression ratio greater than 9.5 usually use 95 octane gasoline. Occasional use once or twice will not have a significant impact. Differences between 92 and 95 octane gasoline: Compression ratio differences: Generally, cars with a compression ratio between 8.5 and 9.5 should use 92 octane gasoline, while cars with a compression ratio greater than 9.5 should use 95 octane gasoline. Octane rating differences: 92 octane gasoline has a lower octane rating than 95 octane gasoline. Specifically, 92 octane gasoline contains 92% isooctane, while 95 octane gasoline has an octane rating of 95%. Price differences: 92 octane gasoline is cheaper per unit than 95 octane gasoline. Gasoline grade selection: Common gasoline grades in China mainly include 92 octane and 95 octane. The gasoline grade indicates the octane rating of the gasoline, with higher octane ratings providing better anti-knock performance. Diesel grades are different from gasoline, as diesel grades represent the freezing point. Refueling precautions: Try not to wait until the fuel warning light comes on before refueling. The fuel pump is located inside the fuel tank and operates at a high temperature when continuously working. Being immersed in fuel helps to effectively cool it down. When the fuel warning light comes on, it means the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the lifespan of the fuel pump. Additionally, having too little fuel or running out of fuel can potentially burn out the fuel pump. If the car has been driven over 30,000 kilometers, extra caution is needed. When the fuel level is too low, the fuel pump may draw in sediment from the bottom of the tank, which can block the fuel pump or obstruct the fuel line.

How to Judge the Distance of the Rear Vehicle When Driving at Night?

Methods for judging the distance of the rear vehicle when driving at night: When the image of the rear vehicle occupies the entire rearview mirror, the distance between the two vehicles is approximately three meters; when the image of the rear vehicle occupies two-thirds of the rearview mirror, the distance is about five meters; when the image occupies half of the rearview mirror, the distance is about nine meters; and when the image occupies one-third of the rearview mirror, the distance is approximately twelve meters. It is important to appropriately increase the following distance when driving at night to prevent collisions between vehicles. Both nighttime and daytime vehicle encounters require certain techniques. During nighttime encounters, switch from high beams to low beams. If the oncoming vehicle does not switch to low beams, immediately reduce speed and use continuous switching between high and low beams to signal them. Also, pay attention to the situation in the right non-motorized lane during encounters.

Why Was the BMW 316 Discontinued?

316's engine has inherent defects, with issues like oil burning instability and high costs. Below is relevant information about the BMW 316i: 1. Exterior Design: The BMW 316i shares a nearly identical appearance with the already available 320i, with the "316i" badge at the rear revealing its identity. Additionally, the new model still adopts a single-sided single-exhaust design. In terms of configuration, the car will be equipped with features such as an electric sunroof, headlight washers, a multifunction steering wheel, and parking sensors. 2. Powertrain System: The BMW 316i, produced by BMW Brilliance, is powered by a 1.6-liter twin-scroll single-turbocharged engine with the model number N13B16B, slightly different from the 1 Series' 1.6T engine (model number N13B16A). This engine delivers a maximum output of 100kW and a peak torque of 220Nm. The transmission system paired with the engine is an 8-speed automatic transmission.

What Does a Three-Way Catalytic Converter Look Like?

Automotive three-way catalytic converters are externally constructed with double-layer stainless steel thin plates formed into a cylindrical shape, with insulating material such as asbestos fiber felt placed between the double-layer plates. Inside, a purifying agent is installed within the mesh partition. Below is relevant information about automotive three-way catalytic converters: 1. Introduction: The automotive three-way catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Principle: When high-temperature vehicle exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of the three gases—CO, HC, and NOx—promoting specific oxidation-reduction chemical reactions. Among these, CO oxidizes at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds oxidize at high temperatures into water (H2O) and carbon dioxide; and NOx is reduced into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thereby purifying the vehicle exhaust.

Does the Avancier have a hybrid version?

The Avancier does not have a hybrid version; all models in the Avancier lineup are essentially pure gasoline-powered vehicles. The Avancier is a mid-size SUV under the Honda brand, with dimensions of 4858mm in length, 1942mm in width, and 1670mm in height, and a wheelbase of 2820mm. The Avancier is equipped with two types of engines: a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. The 1.5-liter turbocharged engine in the Avancier: delivers 193 horsepower and a maximum torque of 243 Nm. This engine reaches its maximum power at 5600 rpm and its maximum torque between 2000 and 5000 rpm. It features VTEC technology and direct fuel injection, with an aluminum alloy cylinder head and block. It is paired with a CVT transmission. The 2.0-liter turbocharged engine in the Avancier: delivers 272 horsepower and a maximum torque of 370 Nm. This engine reaches its maximum power at 6500 rpm and its maximum torque between 2250 and 4500 rpm. It also features direct fuel injection and an aluminum alloy cylinder head and block. The Avancier's remote-controlled electric tailgate is height-adjustable and has memory function. The central control display can connect to the HondaCONNECT (intelligent navigation) system via the built-in TCU without needing external communication tools, providing services like navigation, real-time traffic updates, and online news. Hybrid electric vehicles combine fuel (gasoline, diesel) and electric power, using an electric motor as an auxiliary power source to assist the engine. The primary power source is the engine, supplemented by a battery, working together to save energy. The electric motor provides strong and smooth power during normal driving. Hybrid vehicles benefit from the electric motor's assistance during startup and acceleration, reducing fuel consumption. Simply put, compared to similarly sized vehicles, they offer lower fuel costs.

Will the Mercedes HOLD function damage the car?

HOLD is activated when the vehicle comes to a complete stop after the first brake application, and then a little more pressure is applied. This creates extra pressure, but its purpose is to send a signal to the pressure sensor in the control unit, which is the signal to activate the HOLD function. It does not have any impact on the brake discs. Related details are as follows: 1. HOLD function: HOLD, when translated directly from English, means to hold or keep (something) in place. Modern Mercedes vehicles come standard with the Electronic Stability Program (ESP), and HOLD is a sub-function under this system, known as the hold function. When this function is activated, the vehicle remains in a braked state even when the brake pedal is released, as long as the transmission is in D, N, or R gear. 2. No wear and tear: Mercedes uses an automatic transmission, and the torque converter (which functions similarly to a manual clutch) includes a lock-up clutch. However, this clutch is only engaged when the vehicle is moving at a steady speed. When the vehicle is stationary, it is disengaged, and the power transmission between the engine and the transmission is achieved through the circulation of hydraulic fluid in the torque converter. Therefore, no wear occurs.
