Multiquip EE46462 Engine Cummins QST30-G5 NR2 Tier 2 1MWe

The Multiquip EE46462 is a genuine OEM Engine Cummins QST30-G5 NR2 Tier 2 1MWe designed for the QST30-G5 generator series. As a direct OEM replacement sourced through Multiquip's authorized parts network, this engine meets the original build specification for the QST30-G5 platform. Confirmed fitment for QST30-G5 equipment ensures a straightforward swap with no guesswork on compatibility. DHS Equipment supplies this part to keep your power generation equipment running at full rated output.

Key Features

• Genuine OEM Engine Assembly — Sourced directly through Multiquip's authorized parts channel, this engine matches the original Cummins QST30-G5 NR2 specification for correct displacement, power output, and emissions compliance.
• Tier 2 Emissions Certified — Built to EPA Tier 2 emissions standards, making this engine appropriate for applications and project sites where regulated emissions compliance is required.
• Direct Replacement for QST30-G5 Generators — Engineered as a bolt-in replacement for QST30-G5 series units, with matching mounting, fluid connections, and electrical interfaces to the original configuration.
• 1MWe Rated Output — Matched to the 1 megawatt electric output rating of the QST30-G5 platform, ensuring the generator set can deliver its full rated capacity once the engine is installed.
• Sustained Power Generation Performance — A correctly specified engine keeps the alternator operating at its designed load range; an underspec or worn engine causes voltage instability, derating, and unplanned shutdown under load.

The Cummins QST30-G5 is a turbocharged, aftercooled inline diesel engine purpose-built for large standby and prime power generator applications. It drives the alternator to produce the generator set's rated electrical output, and every aspect of the engine — fuel delivery, cooling capacity, and torque curve — is matched to the demands of continuous power generation duty. When an engine reaches the end of its service life or sustains damage, replacing it with the correct OEM unit — the Multiquip EE46462 — ensures the generator set returns to its original rated performance and emissions compliance rather than being derated or operated outside specification.
