6 Cylinder 290HP QSM11 Diesel Engine For Construction Machinery

QSM11-C engine is a electronically controlled engine for off-road use, with a displacement of 10.8L, power range 290-420HP. The QSM11 engine has a high reputation in global construction machinery industry, it has characteristic of excellent reliability, durability, fuel economy and safety.

The Advantage and features of QSM11 engine:

1. Fully electronic control+low torque, stable power and fast response
CELECT electronic control unit injection: precise injection, multi-stage injection, no black smoke, linear power; has faster response, lower fuel consumption, and lower failure rate than mechanical pumps.
Peak torque at 1400 rpm: Strong starting under heavy load, no speed loss, large torque reserve, suitable for engineering conditions with frequent load changes.
Turbine with exhaust bypass valve: automatic voltage stabilization at high altitude/high load, maintaining over 95% power at 3000 meters, with strong adaptability.

2. Minimalist structure, ultra reliable, and long lifespan (core selling point)
Six cylinder, one cover+high-strength cast iron cylinder body: The main bearing area is 30% larger than that of the same type, resistant to deformation and high pressure, with a major overhaul cycle of 15000+hours and global verification of over 200 million hours.
No EGR, no post-treatment (National Third Edition): with fewer parts, fewer pipelines, extremely low failure rate, stable in high temperature/high dust/humid environments.
Whole machine strengthening: forged steel crankshaft, wear-resistant piston ring, strong connecting rod, no cracking under heavy load, no oil leakage, and minimal major repairs.

3. Low fuel consumption, wide adaptability, and cost savings
Electronic precise combustion: The minimum fuel consumption is ≈ 196 g/kW · h, which is 8-12% cheaper than models of the same power, saving a lot of money in long-term use.
Strong adaptability to oil products: compatible with high sulfur fuels, can refuel in remote areas/construction sites without picking up fuel or clogging the nozzle.
The low-speed economic range is wide: 1500-1900 rpm has the best fuel consumption and saves on both engineering and power generation.

4. Modular, easy to install and maintain, with minimal downtime
Integrated design: 25% fewer parts than similar products, standard interfaces, compact layout, low installation space requirements, and fast transformation.
Centralized maintenance: The machine filter/diesel filter/oil-water separator are arranged on the same side, allowing for quick oil and component changes; The maintenance interval is 500 hours, reducing maintenance costs by over 35%.
