Are gasoline-electric hybrid cars really very fuel-efficient?

Hybrid electric vehicles are different from traditional fuel vehicles. Its drive is powered not only by an engine but also by an electric motor. The two are used alternately under different conditions to reduce fuel consumption. Among them, even hybrid electric vehicles are divided into plug-in and non-plug-in types. The main source of energy for non-plug-in cars is to use electricity to store the car's wasted energy, so their energy comes from gasoline.

Pure electric vehicles rely entirely on starting batteries. When the battery is empty, it must be charged. The range is up to 700 kilometers. The advantage is low vehicle cost.

A hybrid plug is a hybrid electric vehicle with rechargeable oil. Generally speaking, the pure electric range can be 50-100 kilometers. Therefore, its advantage is that it uses electricity when there is electricity and uses oil when there is no electricity.

Invalid speed: When waiting for a red light on a city road, no one will stop for 30 seconds for a red light? Until the engine stops, the engine will always run at idle speed, usually around 800-1000 rpm. This part of the fuel is wasted. Now some fuel vehicles have an "automatic start and stop" function, which is a poor user experience, but it can indeed save fuel. With hybrids, unless there are some special modes, the engine stops running when parked and waiting. The hybrid electric oil system cannot be recharged via an external power source. It is entirely based on an Atkinson cycle engine that provides power to the entire system, just like Toyota and Honda. This engine provides better fuel economy than the high-cycle engines of fuel-only vehicles. This is because the engine part of a hybrid vehicle can maintain stable speed and load, and the extra energy required for acceleration makes the engine have higher energy conversion efficiency. Therefore, it is only suitable for hybrid electric vehicles.

However, with the seemingly perfect energy system, why not buy a lot of knights in normal times? In fact, this is also because many drivers feel that hybrid gasoline-powered vehicles are fuel-saving and money-saving. Hybrid electric vehicles are introduced to reduce fuel consumption and combine the two engine systems to save some fuel costs. But in fact, in other aspects aspects are higher than the fuel cost savings.
