It is normal for the engine to shake slightly at the moment of shutdown. This occurs because the fuel injection is interrupted when the engine is turned off, and the engine transitions from inertial motion to a complete stop. At very low RPM, shaking can occur. Additionally, when the engine shuts off, both the fuel and electrical systems cease operation, causing moving components inside the engine, such as the crankshaft and pistons, to come to an abrupt halt, resulting in vibrations. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle servicing. 2.

Is FAW a Domestic or Joint Venture Brand?

FAW Bestune is a domestic car brand, not a joint venture. Definition of Joint Venture Cars: Joint venture cars are projects jointly established by Chinese and foreign investors. The Chinese side contributes by providing land and factory usage rights, as well as capital, while the foreign investors provide the brand, technology, capital, talent, etc. Joint venture cars are the result of collaboration. Foreign parties provide technology, talent, and brand for assembly within China, but the core technology remains under foreign control.

Core technologies such as car engines and transmissions rely on imports, which results in higher prices for joint venture cars.

Can a 92 car use 95 gasoline?

92 cars cannot use 95 gasoline, as it will affect the service life of the car's ignition system, fuel injectors, and spark plugs. Gasoline can be classified into different types based on its source: straight-run gasoline, catalytic cracked gasoline, thermal cracked gasoline, reformed gasoline, coker gasoline, alkylate gasoline, isomerate gasoline, aromatized gasoline, etherified gasoline, and polymerized gasoline. The working principle of the gasoline supply system is as follows: the fuel transfer pump draws diesel from the fuel tank, filters out impurities through the filter, and then enters the low-pressure oil chamber of the fuel injection pump. After increasing the fuel pressure, it is delivered to the fuel injector through the high-pressure fuel pipe. The fuel injector sprays the fuel into the combustion chamber in a mist form, forming a mixture that burns and performs work. The exhaust gas is then discharged into the air through the exhaust system.

What are the differences between unibody and body-on-frame structures?

The differences between unibody and body-on-frame structures lie in their distinct body constructions: unibody employs a separated load-bearing frame structure, while body-on-frame uses an integrated body structure. Body structure refers to the arrangement of various components forming the vehicle body and their assembly methods. Based on load-bearing methods, body structures can be categorized into: body-on-frame, unibody, and semi-unibody. Body-on-frame vehicles feature a rigid frame (also called chassis frame), where the frame and body are flexibly connected via springs or rubber cushions. Components like the engine, part of the transmission system, and body assemblies are mounted on the frame using suspension systems. Unibody structures integrate components such as the front end, side panels, rear section, floor pan, engine, front/rear suspensions, and part of the transmission system directly onto the body, with body loads transmitted to wheels through suspension systems.
