6.7 Injector Fuel Systems 0445117015 0445120231 Common Rail Direct Fuel Injection

6.7 means that the engine displacement is 6.7 liters. 

Today, I'd like to introduce two Cummins series 6.7L excellent engines.

Cummins ISDE series engine assembly

Dual core control module of continental German company has added OBD and UDS / ODX functions, with faster processing speed and stronger functions, so as to realize the balance among load demand, fuel efficiency and emission control

Powerful control system, control system and optimized fuel system and combustion system cooperate to ensure fuel economy and power performance under different use environments

Bosch third generation high pressure common rail fuel system further improves low-speed performance, fuel economy and cold start performance, and reduces emissions

Strong power : 4-cylinder output torque 760n. M, 6-cylinder output torque 1100n. M, greatly improving engine power reserve and transient response performance, fast acceleration, good climbing performance

Multiple noise reduction and shock absorption measures: double oil pan, silicon oil damper, vibration isolating air valve chamber and other noise reduction and shock absorption measures are adopted, which fully meet the requirements of national standard GB14097-1999 and make the driver more comfortable

Excellent cold start performance: intake preheating, the engine can be ignited successfully even at - 35 ℃ ultra-low temperature.

QSB6.7

The data processing speed of the upgraded electronic control module (ECM) is twice as fast as before; the central injector with symmetrical bowl shaped combustion chamber improves combustion and reduces fuel consumption; the integral cylinder block has increased displacement, stronger structure and lower noise.

Cummins QSB series is a mature model which has been tested by the market for a long time. In this power stage, the engine has more excellent neutral performance.

Qsb4.5 and 6.7 engines have a wide range of power coverage and are widely used in excavators, loaders, rollers, graders, airport ground handling equipment (such as aircraft tractors, power vehicles) and other equipment. In addition, according to the characteristics of the loader, Cummins has customized the QSB6.7 characteristic curve for the loader, which is optimized to match with the host equipment.

The fully electronically controlled high-pressure common rail fuel system ensures the fuel to burn more softly and thoroughly in the cylinder, and reaches the third stage emission standard without using exhaust gas recirculation. The rear gear chamber and flywheel housing are designed as a whole, the structure is stronger, and the noise of gear transmission is further reduced.

General Specifications

Configuration : In-line, 6 cylinder, 4-stroke diesel

Aspiration : Turbocharged/Aftercooled

Displacement : 6.7 liters

Bore & Stroke :107 x 124 mm

Fuel System :Bosch High-Pressure Common-Rail

Due to the excellent performance of the 6.7L engine, the market demand for the 6.7 injector is also huge.

The following are some of the 6.7 injectors models that our company is selling

Advantages of simultaneous injection with electronic injector

The electronic control diesel injection system is divided into several types, and the corresponding injector injection control methods are also different. It can be divided into two main categories: first, the electronic control system only controls the oil pump, the injector has no electronic control, and only opens the needle valve to inject oil as the diesel pressure in the system reaches the starting pressure, such as the electronic control pump nozzle, the electronic control unit pump, the electronic control combined plunger pump, the electronic control distribution pump and other systems; second, the injector is directly controlled, such as the electronic control high-pressure common rail system. Although the nozzle system of the electric control pump is made up of the pump and the nozzle, it only controls the part of the oil pump, not the nozzle. Only the common rail system can achieve multiple fuel injection through the electronic control of solenoid valve or piezoelectric crystal on the fuel injector From the point of view of function, all electronic control diesel injection systems except common rail system basically control the primary injection quantity and injection time, but the injection pressure is affected by the engine (oil pump) speed, in which the system pressure of pump nozzle and electronic control unit pump is high, which can achieve the emission standard in Europe IV, but the common rail system can flexibly achieve multiple injection, and the injection pressure does not change with the rotation Speed change, can meet the Euro 5 emissions.
