Product Description
Small Single cylinder diesel fuel injector
The Small Single cylinder diesel fuel injector assemblies system produced by Huahui Oil Pump Company include three categories: S, P, and common rail series. They can be matched with vortex and direct injection diesel engines with cylinder diameters of 60-120 mm. They have low fuel consumption, low smoke, and good reliability., etc., basically covering medium and small power diesel vehicles and tractors. P series fuel injector is a new variety developed by our company. It is small in size and small in inertia, making it especially suitable for medium and small high-speed diesel engines. The high-pressure common rail series meets the emission requirements of Eurasian and National Fifth Countries and is efficient and energy-saving.
The injector assembly can be called the "fuel injection steward" of the engine. It is responsible for accurately and efficiently injecting fuel into the combustion chamber to perfectly mix fuel and air. Compact structure and reliable quality, effectively improve the combustion efficiency of the engine and enhance power output. It is widely used in various diesel engine equipment to help the equipment perform stably.
Product Description
The Small Single Cylinder Diesel Fuel Injector System is an integrated fuel delivery mechanism designed specifically for compact diesel engines. It ensures the precise injection of atomized fuel into the combustion chamber, optimizing combustion efficiency, reducing emissions, and enhancing engine responsiveness. Ideal for use in lightweight machinery and portable power systems, this injector system combines precision engineering with long-lasting durability.
Product Advantages
Precision Injection Control
Delivers accurate fuel quantities at high pressure for efficient combustion and stable engine operation.
Compact & Durable Design
Engineered for space-constrained environments, the system is built with high-strength materials for resistance to heat, wear, and corrosion.
Fuel Efficiency & Emission Reduction
Fine atomization reduces fuel waste and lowers exhaust emissions, aligning with eco-efficiency standards.
Versatile Compatibility
Suitable for various small diesel engines (e.g., 168F, 170F, 178F), used in mobile and stationary equipment.
Product Applications
This fuel injector system is commonly used in:
Small agricultural machines (mini tillers, walking tractors)
Diesel generator sets
Compact construction tools (plate compactors, concrete saws)
Portable irrigation pumps and water delivery systems
Marine auxiliary engines and backup power units
It is particularly valuable in settings where reliability, fuel economy, and simplicity of maintenance are critical.
FAQ
What is your MOQ?
100 pieces.
Can you design the equipment according to our size?
Yes.
Is this injector system compatible with all small diesel engines?
It is compatible with most standard small single-cylinder diesel engines such as 168F, 170F, and 178F. Please check your engine model or consult with us to confirm compatibility.
What are the symptoms of a faulty fuel injector system?
Common signs include difficult starting, engine misfires, black smoke, increased fuel consumption, or a noticeable drop in engine power.
How often should the injector system be maintained or replaced?
With regular use, cleaning or inspection is recommended every 300–500 hours. Replacement is typically required after 1,000 hours, or sooner if performance declines.
Can I clean the injector myself?
Yes, you can carefully remove and clean the injector nozzle using appropriate cleaning tools and solvent. However, if you're unsure, it’s best to have a technician perform the task.
Do I need special tools to install the injector system?
No special tools are required—basic mechanical tools are sufficient. For optimal results and to avoid damage, professional installation is recommended.
