The main reasons for occasional engine shaking when stopped at a red light are: This is a resonance phenomenon caused by the engine, frame, leaf springs, and tires. The solution is mainly to adjust the RPM slightly higher or lower. It occurs due to natural wear or deformation of bearings and ball joints. Many minor deformations are actually completely imperceptible to the naked eye, but as the vehicle speed increases and centrifugal force grows larger, the oscillating effect caused by bearing deformation becomes more pronounced; hence, the faster the speed, the greater the shaking. Here is some additional information: Function and Types: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. Introduction and History: The term engine can refer to both the power-generating device and the entire machine including the power unit. The engine was first developed in England, so the concept of the engine also originates from English, with its original meaning referring to "a mechanical device that generates power."

Is the Gearbox the Same as the Transmission?

The gearbox is a manual transmission. Here is more information about the transmission: 1. A device that changes the speed ratio and direction of motion. It is used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several components. 2. The transmission is located between the clutch and the central drive. Its main functions are: changing the driving force and speed of the vehicle (shifting gears) while keeping the engine speed and torque constant; enabling the vehicle to move in reverse (reversing); and allowing the engine to idle without stalling (neutral gear).

The Hazards of a Faulty Thermostat to a Car

The hazards of a faulty thermostat to a car are as follows: A faulty thermostat can cause uncontrolled cooling water temperature: When designing the cooling system, the maximum heat dissipation capacity is based on ensuring reliable cooling for the engine under the most challenging conditions, such as high load, low speed, and high external temperature. Obviously, under conditions of low load, high speed, and low external temperature, the heat dissipation capacity is excessive, causing the engine to overcool. A faulty thermostat drastically changes the engine's economy and durability: Without a thermostat, the engine often operates in a low-temperature state, resulting in poor thermal conditions, accelerated wear of components, and increased fuel consumption.
