Main Features
The QSM Quantum System provides superior fuel economy with strong engine performance, engine protection and other programmable features. Components include:
Holset HX55 Wastegated Turbo – Designed for optimum boost, it improves throttle response across operating range.
CELECT™ Electronic Engine Management – Provides superior performance, fuel efficiency, diagnostics and prognostics using full-authority electronics. Its programmable features let you customize engine performance to equipment use.
High-Capacity ECM – New space-efficient Electronic Control Module packs ten times more memory and ten times more processing power.
Sealed Sensors – Fully sealed to resist water intrusion. Combined temperature and pressure sensors reduce inventory and simplify maintenance with increased reliability.
Advanced Combustion Technology – Optimized injector tips and a reshaped steel piston bowl improve fuel economy and emissions control with longer oil change intervals.
Articulated Pistons – Steel-topped pistons handle higher cylinder temperatures for improved fuel efficiency and emissions control.
The Auto-Tensioning Belt Drive – Self-adjusting for optimum tension, which increases fan, alternator and fan belt life.
Improved Camshaft Durability – Exhaust valve lobes are designed to improve wear tolerance. The injector lobe profile has been revised to optimize injection.
