What is the difference between the m20c and m20d engines?

[SanSadie]

m20c and m20d engines differ in their manufacturers: the m20c engine is produced by GAC, while the m20d engine is produced by FAW. Precautions for daily use of the engine include: 1. Use clean fuel, as excessive impurities in fuel can cause wear to the electric fuel pump; 2. Refuel promptly to ensure the engine's electric fuel pump provides sufficient fuel and stable working pressure for the injection system; 3. Do not disconnect electrical equipment circuits when turning on the ignition switch; 4. Regularly clean the fuel system and intake system. A dirty fuel system can lead to a series of issues such as poor fuel flow or blockages, valve leakage, poor fuel atomization, insufficient fuel supply, and low fuel pressure, directly affecting the engine's normal operation.
