tec O.P. Upgrade Kits signed For Efficiency; •iro-Awareness

Coltec Industries' Fairbanks jrse Engine Division has devel- ed a series of upgrade kits for its

P. (opposed piston) engines, fo-

Lsing on improving performance id durability and reducing ex- aust emission levels. Its design llows for flexibility of relative air nd exhaust port timing without he need for backflow valves, and ,akes advantage of an open cham- aer in the presence of high air swirl for optimum combustion. The com- pany reports that its O.P. engine has a two-cycle design with ported uniflow scavenging, and is utilized in primer mover heavy duty appli- cations. The O.P. emissions reduc- tion kits include the following unit configurations: a blower scavenged; a blower-turbo with continuous or intermittent blower; a turbo-blower series; and turbocharged air scav- enging systems. Fairbanks Morse has developed specific upgrade kits for both blower and turbocharged applications, the fifth kit of each group combining and maximizing the improvement of the first four.

Marine Power, Inc. Offers 6.5 Liter Diesel

Marine Power, Inc. of

Ponchatoula, La., offers a new se- ries of 8-cylinder diesel engines built from the 6.5 GM diesel block. It is reportedly ideal for gas to diesel repowers. The 165 hp is naturally aspirated, the 230 hp is turbo- charged and the 275 hp is turbo aftercooled—all measured at 3,600 rpm at the crankshaft. The engine measures 31.5 in. high by 27 in. wide and weighs 1,000 lbs., includ- ing gear. It displaces 396 cu. in. and produces more than 350 ft. —lbs of torque from 1,700 to 3,500 rpm.

Compression ratio is 18.3:1 for the turbo and turbo aftercooled model, and 22:1 for the naturally aspirated model. The diesel features indirect injection for low emissions. Its cast iron block engine uses forged steel connecting rods and caps, cast alu- minum "scuff-proof" pistons and a hardened steel roller camshaft. The cooling system's heat exchanger is equipped with a remote surge tank and low-water alarm.
