Onan, the electric power generation subsidiary of Cummins Engine Co., introduced for the 2001 RV model year what it believes to be the first electronic fuel-injected (EFI) generator for the RV market.

Called the Marquis Platinum, it comes in three variations. The gasoline unit can produce 5,500 or 7,000 watts and the liquid propane (LP) and LP vapor models can produce up to 5,500 or 6,500 watts respectively.

Equipped with four-cycle, 633cc V-Twin OHV engines producing 10.7 to 12.3 bhp, all Marquis Platinum models are capable of simultaneously powering two air conditioners “with energy to spare,” according to Onan.

“The Marquis Platinum is the first ultra-quiet, sequential-port EFI gasoline RV generator,” according to the company. “It offers improved combustion, lower emissions and a new level of electronic microprocessor sophistication never before achieved in an air-cooled RV gasoline genset.”

The Onan line-up for 2001 also includes the Marquis Gold and Emerald Advantage, which, like the Platinum, are fitted with advanced microprocessor hardware and circuitry for easy maintenance and serviceability, according to the company.
