What are the reasons why an automatic transmission car cannot start or ignite?

Possible issues include the steering wheel, parking gear, smart key, battery, etc. Below is an introduction related to automatic transmissions: 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, more gears mean better fuel efficiency. 2. Driving Techniques: For manual transmission cars, it is advisable to shift gears at higher RPMs. Engines are designed to operate at higher RPMs, and parameters such as dynamic balance and rotational inertia of various components are also designed with high RPMs in mind. If the engine operates for extended periods under abnormal conditions, the load and wear on internal components naturally increase, leading to frequent shaking and knocking, which can affect the engine's lifespan. Choosing 3000 RPM as the shifting point ensures that after shifting, the engine operates at around 2300 RPM, keeping it within a healthy RPM range.
