LETON power cummins generator set Basic design features:

LETON power diesel generator set cylinder design is firm and durable, with low vibration and noise; Four stroke, stable operation and high efficiency; Replace wet cylinder liner, long service life and convenient maintenance. Two cylinders and one cover, four valves per cylinder, sufficient air intake, forced water cooling, low heat radiation and excellent performance.

Fuel system:
The patented PT fuel system of Cummins company has a unique overspeed protection device. Low pressure oil pipeline, few pipelines, low failure rate and high reliability. High pressure injection, full combustion. Equipped with fuel supply and return check valve, it is safe and reliable to use.

Air intake system:
Leton power Cummins diesel generator is equipped with dry air filter and air resistance indicator. Exhaust gas turbocharger is used, with sufficient air intake and guaranteed performance.

Exhaust system:
Leton power Cummins diesel generator set uses pulse dry exhaust pipe, which can effectively use waste gas energy and give full play to engine performance. The unit is equipped with an exhaust elbow and exhaust bellows with a diameter of 127mm for easy connection.

Cooling system:
The gear centrifugal water pump is used for forced water cooling, and the large flow channel design has good cooling effect, which can effectively reduce heat radiation and noise. The unique spin on water filter can prevent rust and corrosion, control acidity and remove impurities.

Lubrication system:
Variable flow oil pump, with main oil passage signal pipe, can adjust the oil volume of the pump according to the oil pressure of the main oil passage to optimize the oil volume entering the engine; Low oil pressure (241-345kpa). The above measures can effectively reduce the loss of pump oil power, improve power performance and improve the economy of the engine.

Power take-off:
The crankshaft pulley with double groove power output can be installed in front of the shock absorber. The front end of Leton power generator set is equipped with multi groove accessory drive pulley, which can be equipped with various front-end power output devices.

Ultra low fuel consumption
Cummins xpi ultra-high pressure common rail fuel injection system and CTT large flow turbocharger are adopted, combined with Cummins advanced power cylinder design and electronic control system to greatly reduce fuel consumption and ensure excellent fuel economy of the engine in different working conditions and applications.

Excellent reliability
Using the world's leading engineering technology and analysis tools and combined with the use conditions of Chinese users, with the support of powerful sensors and electronic control system, the engine has stronger high-altitude operation ability, low-temperature operation and large load continuous operation ability. The engine can run freely at minus 40 to 60 ℃ and 5200m altitude, and can output at full load without affecting the output ability.

Super adaptability
The ultra-high weight power density and rising power density are convenient for users to install and transport, and convenient for users to repair and maintain. The cold vehicle can be started instantaneously, and can be loaded 100% at one time, which meets the standard of nfpa110, and the power supply can be completed within 10 seconds. (Better than CNS) the engine is electronically controlled and meets the environmental protection standard of the United States EPA), with four stroke, water-cooled multi cylinder and 1800 rpm.

Low emission
The in-machine purification scheme can meet the use of hospitals, schools and other places with more stringent emission requirements.
