K19 CUMMINS Engine
The Cummins K19 engine is engine with inline 6-cylinder, four stroke, cylinder diameter X stroke of 159*159mm and a displacement of 19L, direct injection that uses a high-pressure turbocharger with lower fuel delivery pressure and higher fuel injection pressure. At the same time, the integral forged crankshaft and connecting rod provide better endurance for the engine, and a large number of internal oil passages are used in the cylinder block to make the engine cleaner
CUMMINS K19 Diesel Engine
The Cummins K19 series engines are widely used in engineering machinery, heavy-duty vehicles, power generation, marine power and other fields. They have won the favor of various fields with strong power, ultra-low fuel consumption, high reliability, and low maintenance costs, and their technology is constantly being upgraded.
KT19
The power range is 425-725Hp, emission level China Stage II, the technical performance indicators have reached the international advanced level
- Localized production: The research and development of steel for exhaust valves and camshafts, crankshaft corner quenching technology, connecting rod shot blasting strengthening technology, rotary gun drilling technology, etc. have filled the domestic gap; China’s first domestically produced crankshaft oil hole electrochemical deburring process and casting room temperature phosphating process.
- Innovative production: Using PEPSET self hardening sand technology, large and complex castings such as cylinder blocks and cylinder heads are manufactured using a box less molding method; In China, the first methods to be used were transparent magnetic testing, black light leak detection, microelectronics, and micro hole inspection. The localization rate of accessories reaches 90-95%. It has been used in important sectors of the national economy such as automobiles, construction machinery, ships, and power generation, and has good economic and social benefits.
KTA19
The power range is 450-890Hp, the engine has a compact structure and is easy to maintain.
- Electronic control module:The fuel system of the QSK19 engine is controlled by the electronic control module ECM, just like other Cummins electronic control engines. The ECM of the QSK19 fuel system adopts Cummins’ latest electronic technology, which has two microprocessors to process and control the necessary data for engine and system operation. It also has 2MB of memory to store calibration information and fault data.
- Unique intake system:This engine is a turbocharged intake system that uses exhaust gas to drive the turbine, which in turn drives a centrifugal compressor to increase intake pressure. The air is then cooled by an intercooler to increase density and enter the cylinder. Composed of air filter, exhaust turbocharger, intercooler, intake pipe, intake manifold, and intake valve.
QSK19
Power range 525-750hp, the engine adopts turbocharging and intercooling technology.
- Electronic control module:The fuel system of the QSK19 engine is controlled by the electronic control module ECM, just like other Cummins electronic control engines. The ECM of the QSK19 fuel system adopts Cummins’ latest electronic technology, which has two microprocessors to process and control the necessary data for engine and system operation. It also has 2MB of memory to store calibration information and fault data.
- Cylinder body design:The cylinder body adopts an integral web plate, which has reached maximum strength and stiffness. There is a large cavity on the right side of the cylinder body for installing an oil cooler, and a concave hole for installing an oil pump at the front end of the cylinder body. On the left side, there are six independent piston cooling nozzle channels, a set of high mounted camshaft shaft holes, and a filter seat mounting platform.
