"Multifuel Engine The multifuel engine (fig. 1-11) is basically a four-stroke cycle diesel engine with the capability of operating on a wide variety of fuel oils without adjustment or modification. The fuel injection system is equipped with a device called a fuel density compensator that varies the amount of fuel to keep the power output constant regardless of the type fuel being used. The multifuel engine uses a spherical combustion chamber (fig. 1-12) that aids in thorough fuel and air mixing, complete combustion, and minimizes knocks."
