compression ignition的意思|示意

The term \"compression ignition\" refers to the process of igniting a fuel-air mixture inside an engine cylinder. This is the same process used in most gasoline engines, but is differentiated by the type of fuel and injection system used. Compression ignition engines are used in diesel vehicles and heavy machinery, and have become increasingly popular due to their increased efficiency and lack of emissions.

Compression ignition engines use a diesel fuel, which is heavier and has a higher energy density than gasoline. This fuel is injected into the cylinder at high pressure, and is then ignited by the high compression of the piston inside the cylinder. The rapid expansion of the fuel-air mixture pushes the piston down, providing the power needed to drive the vehicle.

The majority of cars on the road today are powered by gasoline engines, but the demand for diesel-powered vehicles has been steadily growing. Compression ignition engines tend to be more fuel-efficient and require less maintenance than gasoline engines, making them attractive to those looking to save money on fuel and maintenance costs. Also, due to the higher combustion temperatures created by compression ignition, fewer emissions are released into the environment.

Compression ignition engines have been around for decades, but only recently have they become more affordable and widely available. As this technology becomes more prevalent, it is likely that more and more vehicles will switch over to the diesel fuel-powered option.
