It did have four engines. It only had two propellers. That was part of the problem.
I think you are saying four single engines, yes?

It had the same kind of abomination engines that the Manchester had. Each engine, DB606 and DB610 in the case of the He177 and RR Vulture in the case of the Manchester, was actually made up of two smaller engines, DB 601s for the DB 606, DB 605s for the DB 610 and RR Kestrels for the RR Vulture, locked together and working on a single crank shaft. In each case, DB 606, DB 610 and RR Vulture, the conglomerate is considered a single engine. So the He177 and Manchester are both considered twin engined aircraft while the He277 and Lancaster are four engined aircraft.
