A kind of Porsche engine, but different
Although America is not a diesel country, Cummins is really a household name there. The American company builds potent diesel engines that you will find in pick-ups, but also in trucks, ships and even trains. They recently won a contract from the American government for a special new diesel engine.
Cummins’ new engine is called ACE, which stands for Advanced Combat Engine. The special thing is that it is a boxer engine. The pistons are flat and opposite of each other, as with many Subaru and Porsche engines. A boxer set-up is certainly not common with diesel engines. Subaru was the first to make a diesel boxer for a passenger car in 2008, and there have been few other brands since then.
What makes the Cummins ACE so special?
According to the engine manufacturer, the Cummins ACE is 13 percent more efficient than comparable military engines. In addition, the engine is scalable, allowing them to produce three, four and six cylinders. Three-cylinder? Yes, apparently you don’t necessarily need an even number of pistons with a boxer engine. Power ranges from 750 to 1,500 hp. The latter gets two turbos. In addition, there is a possibility to apply electrification if necessary.
Another advantage of the new Cummins ACE is that the engine is compact. This leaves more room for armor, which is quite important with military vehicles. In addition, it allows the engine to easily fit into existing vehicles, such as the M88 armored vehicle. Cummins will receive a total of $87 million for the development of the new diesel boxer engine.
