Combustion efficiency
The precision of the fuel nozzle has a direct impact on the degree of fuel atomization. High precision nozzles can atomize fuel into very fine and uniform particles. These tiny fuel particles mix more fully with the air, creating a more uniform mixture in the cylinder. When the spark plug ignites, the mixture can be completely burned in an instant, and combustion efficiency is greatly improved. For example, in high-performance engines, high-precision nozzles can atomize the fuel into particles of about 20 - 30 microns in diameter, and this good atomization effect can make the engine's combustion efficiency increase and output more powerful.

Poor precision nozzles may result in poor fuel atomization. Large and uneven fuel particles will prevent the fuel from mixing well with the air. During combustion, part of the fuel is not able to participate in combustion in time, but is discharged in liquid form, which not only reduces combustion efficiency, but also increases the emission of harmful components in the exhaust gas, such as hydrocarbons (HC) and carbon monoxide (CO).

In terms of cold start performance
Good fuel atomization is also critical to the cold start performance of the engine. During cold starts, when engine temperatures are lower, high-precision nozzles are able to atomize the fuel more finely, making it easier to form a combustible mixture. This allows the engine to start more easily at low temperatures and reach a stable idle more quickly after starting.

Poorly accurate nozzles may not atomize the fuel well during cold starts, making it difficult to start the engine, or even requiring multiple starts to be successful. And after starting, the engine may shake and run erratically because of poor mixing of fuel and air and inadequate combustion.

Injector nozzle, this car engine is inconspicuous but vital components, with millimeters of subtle design and stable play, quietly guarding the vehicle power surging, driving smoothly, and become a mechanical world of small but great existence model.
