Private equity firm the Carlyle Group LP (Nasdaq: CG) completed its acquisition of Walbro Engine Management.

Terms of the transaction remain undisclosed. The deal comes on the heels of Carlyle wrapping up its $3.3 billion acquisition of a controlling stake in media distributor Getty Images Inc.

The Walbro sale, announced in September, marks an exit for private equity firm Sun Capital Partners Inc., which purchased the Tucson, Ariz.-based firm in 2007.

Carlyle, based in Washington, D.C., has more than $156 billion in assets under management. Equity for the investment comes from Carlyle's second Japanese fund, Carlyle Japan Partners II, the buyout firm said in a release. Walbro, a maker of air and fuel-ignition systems for the non-automotive engine market, has research and development facilities in Japan and the U.S., as well as factories in Thailand, China and Mexico.

Sun Capital is headquartered in Boca Raton, Fla.
