Equipment: Komatsu PC360-7 Hydraulic Excavator
Problem: Persistent engine overheating during operation
Diagnosis: After comprehensive inspection, the issue was traced to a faulty water pump and clogged radiator cores. The water pump impeller was corroded, reducing coolant circulation efficiency, while the radiator had accumulated debris and mineral deposits.
Solution: Replaced the water pump with a genuine Komatsu part and performed thorough radiator cleaning using specialized flushing equipment. Additionally, installed a new thermostat and replaced coolant with OEM-specified antifreeze.
Result: Engine operating temperature returned to normal range (82-88°C), and overheating issues were completely resolved. Equipment productivity improved by 25% with no further temperature-related downtime.
Preventive Measures: Recommended regular cooling system inspection every 500 operating hours and radiator external cleaning every 250 hours in dusty environments.
The Chongqing Cummins K19 engine represents a significant advancement in diesel engine technology, designed specifically for heavy-duty applications in construction, mining, and power generation sectors. This engine series features:
Advanced Fuel System: High-pressure common rail injection for optimal combustion efficiency

Cummins K19Performance characteristics of engine products
|  • power Power covers 450-890 horsepower and torque is 2586 Newton meters.   The weight of the self-weight is 1838 kg, and the power and weight ratio is large.   • Low fuel consumption and good economy  Cummins technology PT fuel system, ultra-high injection pressure, good atomization and sufficient combustion of the engine. The efficient Holset exhaust gas turbocharger can ensure more intake, improve engine efficiency, further improve combustion, and reduce engine fuel consumption. Air-air cooling technology has better air intake and better fuel economy.   • Compact structure and easy to maintain Wet cylinder liner can be replaced, with good heat dissipation effect and easy replacement. All models have strong versatility, high degree of serialization, and easy to maintain. Both the cylinder block and the cylinder head adopt a built-in pressure lubricating oil channel, which has a compact structure and a low failure rate. | |
|      • Design Reliable performance Cylinder: Made of high-strength alloy cast iron, good rigidity, low vibration and low noise. Cylinder head: Four valves per cylinder are designed, optimized air/fuel mixing ratio, and ensure combustion and emissions; one cover per cylinder, which is easy to maintain. Camshaft: The single camshaft design can accurately control valves and fuel injection timing, and the optimized cam-shaped line can reduce impact force, improve reliability and durability. Crankshaft: The integrated crankshaft made of high-strength forged steel, the induction hardening process of rounded corners and journals can ensure higher crankshaft fatigue strength. Piston: Use aluminum alloy casting technology, the ω-shaped head and barrel skirt design can compensate for thermal expansion and contraction, ensuring good cooperation.   • Professional configuration quality Lubrication system: All moving parts are forced lubricated; large-capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; engine oil cooler, full flow filter, and bypass filter maintain good engine oil condition. Fuel system: Cummins technology PT fuel system, optimized combustion and strong power; STC distributed timing system has better combustion in all working conditions; low-pressure oil supply system is used, and fuel unidirectional circuit is equipped, . Cooling system: Forced water cooling is adopted for gear centrifugal water pump, with a large flow water channel design, and good cooling effect; rotary water filter and special DCA additives can effectively prevent rust and cavitation, control the acidity of the coolant and remove impurities. Intake and exhaust system: The efficient Holset exhaust gas supercharger further improves combustion; the pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; the air-to-air intercooling technology has better fuel economy and emissions.   • Mature products,   Wide application: Since Cummins entered China in 1975, the K19 series engine has been widely used in engineering machinery, heavy vehicles, power generation, marine power and other fields; it has formed strategic partners with important customers. High reputation: As one of the main models of the Cummins family, the K19 series engine has won high recognition from customers in various fields for its strong power, maximum fuel consumption, high reliability and low maintenance costs. Technology upgrade: technologies such as air-cooling and slow start have further improved the engine's reliability, power, fuel economy and emission indicators. The QSK19 engine launched in 2008 adopts electronic injection technology and has a power of 369-669kW, which can meet the third-stage emission standards of non-road mobile machinery, further enhancing CCEC's high-horsepower engine manufacturing industry in China. | |
