New High Quality Diesel Nozzle DLLA144P144 0 433 171 130 for Injection Nozzle Diesel Engine Parts

To select a suitable injector nozzle for a specific engine, you need to consider the engine's technical parameters, working conditions, performance requirements and other factors. The following are the specific points:

Consider the engine type
Gasoline engine: Manifold injection engines can choose nozzles with low injection pressure and spray shapes that can evenly mix the fuel and air in the intake manifold. Direct injection engines require nozzles with high injection pressure, precise spray, and can adapt to high temperature and high pressure.
Diesel engine: Diesel engines with direct injection combustion chambers often use hole injectors, which have many small spray holes and high injection pressure. Diesel engines with swirl chamber and pre-combustion chamber combustion chambers mostly use axial needle injectors, which have large spray holes and relatively low injection pressure.

Pay attention to engine parameters
Displacement: Large displacement engines usually require injector nozzles with larger flow rates to provide enough fuel to meet their power output requirements.
Compression ratio: High compression ratio engines require injector nozzles that can accurately spray the right amount of fuel in a short time to adapt to the rapidly changing pressure and temperature during the compression process.

Match working conditions
Ambient temperature: For engines working in low temperature environments, the injector nozzles need to have good low temperature starting performance and be able to quickly atomize fuel. In high temperature environments, the high temperature resistance of the nozzles and the ability to prevent fuel vapor blockage should be considered.
Altitude: The air is thin in high altitude areas, and the engine requires the injector nozzles to adjust the injection amount accordingly according to the reduction in air volume to ensure the correct air-fuel ratio.

Combined with performance requirements
Power performance: Engines that pursue high performance, such as racing engines, require injector nozzles to have high flow and fast response characteristics to provide sufficient fuel at high speeds and high loads.
Fuel economy: Engines with energy saving as the goal require injector nozzles to accurately control the injection amount, achieve an ideal air-fuel ratio, and improve fuel utilization.

Reference to other factors
Brand and quality: Choose injector nozzles of well-known brands and reliable quality, which are more guaranteed in terms of materials, manufacturing processes and quality control, and can ensure stable operation of the engine.
Cost factors: Under the premise of meeting the engine performance requirements, choose injector nozzles with appropriate prices according to the budget. At the same time, the subsequent maintenance costs should be considered, such as whether it is easy to purchase and the cost of replacement.
