Description
Product Overview
The 326-4700 electronically controlled injector is the core injection assembly of the diesel common rail power system. It precisely controls the opening and closing of the internal valve group through the bottom electronic control component, accurately regulating the fuel injection volume and timing. After long-term high-temperature operation, nozzle blockage, internal valve wear, and seal failure can cause various fuel supply failures. This complete assembly can directly replace aging and damaged parts, restore stable engine power output, and is suitable for maintenance and replacement of various small and medium-sized engineering equipment.
Unique Core Features of the Individual Product
Side-mounted inclined threaded fuel inlet connector, suitable for narrow assembly space
The bent fuel inlet threaded port on the side of the body changes the traditional straight-up and straight-down oil routing layout. Even in a cramped cylinder block installation space, it can smoothly connect to the pipeline without causing oil pipe bending and compression or blockage of the oil flow.
Exposed bottom external electronic control pins, convenient for maintenance and disassembly
The electronic control wiring structure is set at the bottom of the injector. During disassembly, there is no need to avoid surrounding pipelines. Independent detection of circuit signals does not require disassembling the entire machine, making it easier for maintenance personnel to troubleshoot circuit faults and replace parts.
Multi-level segmented combined valve body, layer-by-layer buffering of high-pressure impact
The valve body is divided into multiple independent alloy structures, combined with an internal ring-shaped sealing rubber ring to distribute the oil pressure impact force layer by layer. High-pressure fuel will not leak through the joint gaps of the valve body, and the sealing structure is less likely to age and fail under long-term high-temperature conditions.
Conical slender precision nozzle, uniform atomization to reduce carbon deposits
The front end has an extended conical spray head, with fine and uniform micro-pores. The fuel is atomized into fine particles, ensuring complete combustion in the cylinder, slowing down the accumulation of carbon deposits on the nozzle and piston, and reducing the frequency of daily cleaning and maintenance.
Composite wear-resistant coating on the surface, resistant to oil stains and corrosion
The middle section of the valve body uses a composite anti-rust coating. It is not prone to rusting, peeling, or corrosion in long-term contact with diesel, water vapor, and dust environments. The valve body joint clearance remains stable for a long time, and there will be no problems such as pressure leakage or injection deviation. Applicable scenarios
This product is compatible with the corresponding series of electronic control common rail diesel power units. It is mainly used in small and medium-sized excavators, wheeled loaders, agricultural heavy machinery, mobile power generators, and is suitable for the fuel supply system replacement in construction sites, fields, and short-distance outdoor environments with alternating high and low temperatures.
