Cummins Announces Availability Of New XA' Series Diesel Engines

—Literature A v a i l a b l e— Cummins Engine Co., Inc., which acquired majority ownership of Onan Corporation in early 1986, recently announced an agreement with Hawker-Siddeley and Onan Corporation whereby Cummins will assume responsibility for the Onan L series diesel engines. Under this agreement, which covers only the L series diesel engines and not the gasoline models, the engine will be designated the Cummins A series. With the addition of the A series, Cummins power range will be expanded to 41 horsepower on the low end. This enables Cummins to offer diesel power for a wide variety of applications requiring from 41 to 9,000 horsepower.

The A series is strategically important to Cummins in three areas: 1) Automotive: Since the A series has a small package size and the capability to run at 3,600 rpm, it provides an excellent alternative for customers who have traditionally used gasoline engines, but who want the fuel savings and durability of diesel. In essence, the A combines the strengths of both the gasoline and diesel engines. 2) Industrial: Cummins is encouraging the worldwide industrial OEM's to standardize on Cummins throughout their product range, but to date have not been able to offer a cost-effective engine at the low end. The A series fills this void. 3) New markets: The A series also provides entry into several new markets: ground support, welders, lift trucks, and mobile refrigeration. Cummins thinks this engine will be particularly strong in the U.S. mobile refrigeration market. The Cummins A series engine family consists of three-, four-, and six-cylinder naturally aspirated models, as well as a six-cylinder turbocharged model. Plans are also in place to develop a four-cylinder turbocharged model. These engines, which are smaller than the Cummins B series, offer a wide power range of 41 to 120 hp at 3,600 rpm (compared to the B series automotive rating of 105 to 186 hp at 2,800). The A is designed as an in-line, four-stroke, water-cooled engine and employs an indirect injection system.

This new engine family, which began production in September 1981, was designed to provide optimum application flexibility, in order to serve various markets. It was released in 1987 by General Motors as a special equipment option in the P-40 stripped chassis, and began production in the Ford E350 stripped chassis in Venezuela in January 1988, and will begin in the U.S. in March 1988. It is also used in generator sets, marine auxiliary propulsion, small industrial equipment, and automotive repower applications. The Cummins A engine will continue to be manufactured at Onan's Huntsville, Ala., manufacturing facility. Product development will remain in Fridley, Minn. Marketing and aftermarket support will be transferred to Cummins marketing, parts and service groups in Columbus. For further information and specification details on the Cummins A series diesels,
