QSK78 G-Drive engine provides the optimal combination of productivity and performance. Its 4060-horsepower (3028 kWm) V18 configuration incorporates the best features of our QSK Series engines, including advanced combustion technology and robust base engine components.
Featuring a high pressure (HPI-PT) full authority fuel system, the engine meets Tier 2 and 2gTA Luft emissions and has exceptional fuel efficiency. The CM2250 ECM provides the Power Generation Interface (PGI), the widely accepted SAE J1939 industry standard CAN based communication network and advanced engine protection, ensuring faster connectivity along with a superior fault-finding capability.
Plus, the QSK78 comes with optional features like ELIMINATOR™, CENTINEL™, and Prelub™, which help to significantly reduce downtime for routine maintenance.
Every QSK78 engine is covered by Cummins base warranty, one of the most comprehensive and simplest plans in the industry.
CTT (Cummins Turbo Technologies) HX82/HX83 turbo-charging – Utilizes exhaust energy with greater efficiency for improved emissions and fuel consumption.
Ferrous Cast Ductile Iron (FCD) Pistons – The design and material used in these types of pistons ensure increased engine efficiency and durability. Reduces ‘piston slap’ and increases power efficiency.
High Pressure Injection Fuel System – Provides a high-peak injection pressure for optimum combustion for low emissions and better fuel economy. HPI fuel injection provides a “soft” injection start for lower combustion noise.
Low Temperature After-cooling – Enabled by a Two-Pump Two-Loop (2P2L) cooling system that utilizes 2 separate cooling circuit that allows for longer engine durability and fuel economy.
G-Drive Integrated Design – Each component has been specifically developed and rigorously tested for G-Drive products, ensuring high performance, durability and reliability.
Service and Support – G-Drive products are backed by an uncompromising level of technical support and after sales service, delivered through a world class service network.
