China-Lutong Nozzles are designed to withstand the heavy demands of today’s diesel engines. On average, a diesel nozzle fires 1,000 times per minute, so precision and durability are important features. Each China-Lutong Nozzle is engineered for exacting precision and durability, to deliver a long, reliable service life for consistently superior diesel engine performance.
An injector nozzle is a fine sprayer through which fuel is injected into an engine. The top of the injector nozzle has a lot of holes to deliver a spray of diesel fuel into the cylinder. The higher the pressure, the smaller the injector nozzle openings can be, producing smaller pulses that provide better fuel atomization. The fuel is sprayed through an injector nozzle, typically at high pressure, to improve the mixing of fuel with air.caterpillar pencil nozzle
China-Lutong Nozzles are 100% factory tested and calibrated to specifications using the same test equipment to insure the highest level of performance and cleanliness compliance. As a result, customers receive high quality products - not only the first time, but every time.

Common Rail is now the most common fuel system in diesel vehicles. Diesel engine performance and emissions are closely related to fuel atomization and spray processes, which in turn are strongly influenced by nozzle geometry.
Injection nozzles for diesel engines inject the fuel into the combustion chamber, atomize it and seal the combustion chamber by means of the nozzle needle. In the Common Rail System, the injection nozzle is part of the injector.

The injection nozzle consists of the nozzle body the cone of which protrudes into the combustion chamber. The injection orifices through which the fuel is injected are bored in the nozzle cone. The number, configuration, length and diameter of these injection orifices permit the shape of the injection spray to be formed in a way that is ideally matched to the engine cylinder.
Inside the nozzle body is the nozzle needle which, when closed, blocks the injection orifices. For fuel injection, the nozzle needle is raised by the hydraulic servo system of the injector so that the injection orifices are opened. The faster the nozzle needle can be opened and re-closed, the more precisely the injection rate can be controlled.

The injection rate and the shape of the injection spray have a decisive influence on fuel consumption and raw emissions from the engine.

Most heavy-duty diesel trucks have a well-earned reputation for being tough and it’s not hard to find one with an incredible mileage total on the clock. But injector nozzles face two major stresses: engine heat and poor fuel quality. Even on a well-maintained truck, hundreds of thousands of miles on the precision surfaces inside diesel injector nozzles can add up. Microscopic particulates can score the seating surfaces inside the injector body, compromising the seal and causing leaks. Similarly, the injector nozzle tip is exposed to the inside the engine where it sees extreme heat cycling and the products of combustion. When the tiny passages within the nozzle are compromised it results in a loss of power, poor running, increased crank times, and excessive fuel consumption.
