Description

Perkins' all-new 1104D engine assembly is a high-performance power unit tailored for CAT excavators, specifically designed to be fully compatible with the CAT C4.4 engine platform—commonly used in mid-sized excavators (15-25 tons) for construction, landscaping, and light mining tasks. As the core power source of the excavator, this assembly integrates a 4-cylinder turbocharged diesel structure, advanced electronic control system, fuel injection module, and cooling system, all calibrated to match the mechanical and electrical specifications of CAT excavators.

Built on Perkins' decades of diesel engine technology, the 1104D assembly adheres to CAT’s strict quality and performance standards for excavator power units. It undergoes rigorous factory testing, including dynamometer performance trials, endurance runs under simulated excavator working conditions, and compatibility verification with CAT’s hydraulic and electrical systems. The engine is optimized for the high-load, intermittent operating characteristics of excavators, effectively avoiding issues like power mismatch or system incompatibility that may occur with non-specialized engines.

Advantage

Seamless CAT C4.4 Compatibility: Fully matches the mounting dimensions, interface protocols, and power output parameters of CAT C4.4 engine slots in excavators. The hydraulic pump connection flange, electrical connector, and cooling system interface are 1:1 compatible with CAT excavator chassis, enabling direct replacement without modifying the engine bay or auxiliary systems.
Enhanced Power & Fuel Efficiency: Adopts Perkins’ advanced combustion optimization technology (ECOplus) and a high-efficiency turbocharger, delivering 10-15% higher power density than the traditional CAT C4.4 engine while reducing fuel consumption by 8-12%. For mid-sized excavators, this translates to 10-15% faster digging cycles and lower operational costs.
Durable & Low-Maintenance Design: The cylinder block uses reinforced gray cast iron, and the piston adopts a wear-resistant ceramic coating; the fuel system uses a high-precision filter to tolerate low-quality diesel. Maintenance intervals are extended to 500 hours (oil change) and 20,000 hours (major overhaul), reducing maintenance frequency by 30%.
Emission Compliance & Environmental Friendliness: Equipped with a selective catalytic reduction (SCR) system and diesel particulate filter (DPF), meeting EU Stage V and China National IV emission standards. Eliminates the need for frequent regeneration operations, adapting to environmental regulations in mainstream construction markets.

Performance

Power & Torque Output: Delivers 100-140 HP (depending on configuration) with peak torque of 500-650 N·m, achieved at 1400-1800 rpm—perfect for excavator digging and lifting scenarios. The low-speed high-torque characteristic ensures strong breakout force (up to 180 kN) without stalling under heavy loads.
Operational Stability: The electronic control system (ECU) integrates load-sensing technology, automatically adjusting fuel injection according to excavator workload. Vibration amplitude is reduced by 25% via a balanced crankshaft design, minimizing operator fatigue and reducing wear on the excavator’s hydraulic system.
Extreme Condition Adaptability: Works stably in ambient temperatures from -30°C to 55°C and at altitudes up to 3500 meters. The optional pre-heater ensures reliable cold starts (-30°C), and the high-efficiency cooling system maintains optimal operating temperature (85-95°C) during continuous heavy-load operation.
Long-Term Reliability: Under standard maintenance, the average service life reaches 25,000-30,000 working hours, 20% longer than the traditional CAT C4.4 engine. The annual failure rate is less than 1.5%, ensuring continuous operation of excavators in time-sensitive construction projects.
