Feature c-ategory

Detailed Advantage Description

Precision Fuel Injection

Adopts ultra-precision CNC fine grinding process, internal clearance controlled within 1-2μm, ensuring consistent fuel volume and accurate injection timing. Forms even conical spray pattern for full combustion, reducing fuel consumption by 8-10% and eliminating black/white smoke, fully restoring engine power and torque under heavy load.

Extreme Durability

Made of high-strength heat-treated alloy steel with double surface hardening and anti-corrosion coating, resistant to diesel corrosion, high-pressure impact and continuous friction. Withstands over 1.4 million injection cycles under heavy load, extending service life and avoiding frequent replacement costs and unexpected shutdown losses.

Direct OEM Fit

Manufactured 1:1 per original c-at 3116 engine dimensions and interface standards, true plug-and-play installation. No modific-ation or re-calibration needed, perfectly matching original fuel rail and mounting position, cutting maintenance time and labor costs for field and workshop repairs.

Harsh Environment Adaptability

Optimized for tough working conditions, stable in high-temperature construction sites, dusty mines and humid marine environments. Maintains consistent performance under variable load, preventing engine misfiring, rough idle and sudden breakdowns, adapting to all c-at 3116 engine applic-ation scenarios.

Item Type

Specific Content

Common Engine Faults Solved

1. Engine power loss, slow acceleration and insufficient heavy-load torque; 2. Excessive fuel consumption and high operating costs; 3. Abnormal exhaust emissions and visible smoke; 4. Rough idle, frequent stalling and abnormal noise; 5. Injector fuel leakage and engine oil dilution

Installation & Maintenance Tips

1. Recommend replacing all cylinder injectors in sets for balanced performance, avoid mixing old and new parts; 2. Clean fuel system, flush pipelines and replace fuel filter before installation; 3. Use calibrated torque wrench following c-at factory standards to prevent leakage; 4. Idle engine 5-10 minutes after installation, check for leaks before heavy-duty use
