Overview#
The MTU 4R0113 DS100 is a 100 kW EPA Tier 3 certified diesel standby generator set built on the John Deere 4045HF285 — a 4.5-liter, 4-cylinder turbocharged and air-to-air aftercooled diesel producing up to 118 kWm gross. The turbocharger and aftercooler enable the same 4.5L displacement as the DS50 to deliver double the standby output with improved thermal efficiency.
The DS100 uses the John Deere Electronic Control Unit (JDEC) with SAE J1939 communication to the MTU digital control panel, enabling electronic isochronous governing (±0.25% speed regulation), remote diagnostics, and comprehensive fault logging. This is a departure from the mechanical droop governor used in the smaller DS50, providing tighter frequency regulation for sensitive loads.
Standard equipment includes a unit-mounted radiator rated for 50°C (122°F) ambient, 12V electric start, and the MTU digital control panel with NFPA 110 compatibility and IP 54 front panel rating. Optional UL 2200 listing, IBC seismic certification, and OSHPD pre-approval are available.

Our Service Experience#
The 4R0113 DS100 is a workhorse in the commercial standby category. The 4045HF285's turbocharged configuration delivers strong load-acceptance performance, but the charge air cooler warrants close attention. Any coolant leakage into the intake manifold — evidenced by white smoke at startup or unexplained coolant loss — must be diagnosed immediately. On a 4-cylinder turbocharged diesel, coolant ingestion can result in hydrostatic lock damage within seconds.
The JDEC electronic governor is a significant reliability improvement over mechanical droop at this power level. Fault isolation requires John Deere ServiceAdvisor or equivalent diagnostic software — factor this into service contract planning for remote installations. The SAE J1939 integration with the MTU control panel provides live engine data and event recording, which is valuable for post-event analysis after a utility outage.
Frequently Asked Questions#
What is the emissions compliance on the 4R0113 DS100? The DS100 is EPA Tier 3 certified and also carries South Coast Air Quality Management District (SCAQMD) certification, making it eligible for California SCAQMD installations without modification.
How does the DS100 differ from the DS50 at the engine level? The DS100 uses the turbocharged-aftercooled 4045HF285 with electronic isochronous governing versus the DS50's naturally aspirated 4045TF280 with mechanical droop. The turbocharger and aftercooler deliver double the output from the same 4.5L displacement, with improved fuel efficiency per kW and tighter frequency regulation.
What voltages are available on the DS100? Available in 120/240V single-phase and three-phase configurations including 120/208V, 120/240V, 277/480V, and 347/600V.
Is OSHPD pre-approval available? Yes. The 4R0113 DS100 is eligible for optional IBC seismic certification and OSHPD pre-approval, making it suitable for California healthcare facilities.
