4. Cummins generator set basic performance characteristics:
(1) Cummins diesel generator set basic design characteristics: Cummins diesel generator set cylinder design is durable, small vibration, small noise; Four strokes, smooth operation, high efficiency; Replace wet cylinder liner, long service life, easy maintenance; Two cylinders with a cover, each cylinder with 4 valves, full air intake, forced water cooling, small heat radiation, excellent performance.
(2) Cummins diesel generator fuel system: Cummins patented PT fuel system with unique overspeed protection device; Low pressure oil pipeline, less pipelines, low failure rate, high reliability; High pressure injection, full combustion. Equipped with fuel oil supply and return oil one-way valve, safe and reliable use.
(3) Cummins diesel generator intake system: Cummins diesel generator assembly with dry air filter and air resistance indicator, the use of exhaust gas turbocharger, sufficient air intake, performance is guaranteed.
(4) Exhaust system of Cummins diesel generator set: Cummins diesel generator set uses pulse dry exhaust pipe, which can effectively utilize exhaust energy and give full play to engine performance; The unit is equipped with exhaust bend pipe and exhaust bellows pipe with diameter of 127mm for easy connection.
(5) Cummins diesel generator set cooling system: Cummins diesel generator set engine adopts gear centrifugal water pump forced water cooling, large flow channel design, good cooling effect, can effectively reduce heat radiation and noise. Unique rotary water filter prevents rust and corrosion, controls acidity and removes impurities.
