Introduction to the Gears of MG5 Automatic Transmission?

The gear positions of the MG5 automatic transmission, from top to bottom, are P (Park), R (Reverse), N (Neutral), D (Drive), and S (Sport mode). Below is a related introduction to automatic transmission: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, the more gears there are, the more fuel-efficient the transmission is. 2. Manual Transmission Cars: They should shift gears at higher RPMs. The engine is designed to operate at higher RPMs, and the dynamic balance and rotational inertia of various components are also designed with high RPMs as the reference value. If the engine operates for a long time under non-standard conditions, the load and wear on internal components naturally increase, leading to frequent occurrences of shaking and knocking, which can also affect the engine's lifespan.

Is a Long-Term Fuel Trim of -14.7 Rich or Lean?

Long-Term Fuel Trim -14.7 indicates a rich condition. Below is additional information: 1. Fuel Standards: Typically, long-term fuel trim parameters range from -23% to 16%. A value of 0 means no fuel compensation is needed to achieve the correct mixture concentration. A positive value indicates the injection system needs to inject additional fuel, suggesting the engine's air-fuel mixture is lean, which usually makes the vehicle hard to start. A negative value means the injection system needs to reduce fuel to correct an overly rich mixture, so a negative long-term fuel trim indicates the vehicle's air-fuel mixture is too rich. 2. Long-Term Fuel Trim Standard: Generally ±5%. Exceeding this standard likely indicates an engine fault. If the vehicle's injectors are clogged, both fuel injection volume and atomization effect will be poor, resulting in a leaner combustible mixture in the engine cylinders.
