Overview#
The MTU 10V0068 GS100 is a 100 kW natural gas or liquid propane standby generator set built on MTU's own 6.8LT V10 — a 6.8-liter, 10-cylinder V-configuration turbocharged spark-ignition engine with a liquid-cooled ball-bearing turbocharger. The V10 engine architecture is unusual at this power level and gives the GS100 a compact footprint relative to its output, with the unit measuring under 87 inches in length.
The engine is equipped with a 3-way catalyst for low emissions and is EPA certified. It supports dual-fuel operation with factory-configured natural gas and liquid propane options, making it well suited to installations where backup fuel supply continuity is a priority. The Bosch governor provides electronic isochronous control, though speed regulation is listed as consult-factory rather than a fixed percentage — confirm with the distributor for your application.
Standard equipment includes a unit-mounted radiator rated for 50°C ambient, 12V electric start, dual-fuel capability as an option, and the MTU digital control panel with SAE J1939 communications, NFPA 110 compatibility, and IP 54 front panel rating. Optional UL 2200 listing and IBC seismic certification are available.

Our Service Experience#
The V10 architecture is compact and mechanically interesting but requires technician familiarity with the engine layout — the cylinder arrangement means some service points are less accessible than on an inline engine of equivalent displacement. The 3-way catalyst requires periodic inspection; catalyst efficiency typically degrades after 8,000–12,000 operating hours depending on gas quality and operating profile. MTU Onsite Energy distributors can provide emissions testing and catalyst replacement scheduling.
Dual-fuel installations using liquid LP require careful commissioning of the fuel regulator. LP liquid supply pressure must be maintained within the specified range (max 312 PSI); over-pressure or excessive temperature at the regulator can cause erratic operation. Natural gas installations are generally less maintenance-intensive.
Frequently Asked Questions#
What is the MTU 6.8LT V10 engine? The 6.8LT V10 is MTU's own spark-ignition gaseous-fuel engine in a 10-cylinder V configuration. At 6.8 liters, it achieves 100 kW standby output with a turbocharged configuration. It is distinct from the John Deere 6.8L diesel used in the R-series diesel models.
Can the GS100 run on liquid propane? Yes. The 10V0068 GS100 is rated for 100 kW standby on both natural gas and liquid propane. A dual-fuel configuration allowing switchover between NG and LP liquid is also available as a factory option.
What emissions certification does the GS100 carry? The engine is EPA certified with a 3-way catalyst for stationary emergency standby applications. Consult your MTU Onsite Energy distributor for the current emissions data sheet applicable to your jurisdiction.
What gas supply pressure is required? For vaporous supply (natural gas or LP vapor): 178–279 mm H₂O (7–11 in. H₂O). This is a relatively low inlet pressure — confirm that site gas pressure at the generator connection meets this range before installation.
