Product Description
QSX is a new engine developed by Cummins for the 21st century. It adopts a double overhead camshaft design, which can produce greater traction and braking force. There is also a variable output turbocharging system, which can output more power when the engine speed is high, and increase the engine's air intake when the engine speed is low, thereby improving the response characteristics of the system. Using advanced in-cylinder combustion technology, the QSX engine not only meets the third-stage emission standards (Tier 3) of European and American off-road mobile equipment, but also has a technology platform for the fourth-stage emission (Tier 4).QSX15 Engine Specifications

Performance characteristics and advantages
1.Double overhead camshaft: The first camshaft drives the high-pressure fuel system, and the second camshaft controls the intake and exhaust valves. 2.The patented turbocharger with wastegate valve can output maximum power at various speeds. 3.High-pressure fuel system, the combustion is cleaner and more efficient, and the fuel injection pressure is as high as 30,000 psi. 4.The Quantum electronic control system optimizes engine operating performance. The intelligent electronic control system makes QSX's fuel applicability wider. Kerosene can be used without diesel. 5.Heavy-duty piston rings, pistons, bearings, made of high-strength alloys, with a service life of more than 21,000 hours (35% load rate). 6.Engine protection system to minimize damage and downtime 7.The downtime is shorter, due to the longer maintenance interval.Product Pictures
