Internal Combustion Engine with Homogeneous and Heterogeneous Charge 940900

ABSTRACT

A conventional diesel engine provided with divided combustion chamber, having the capacity to operate with a broad variety of fuels, with low emissions and low specific fuel consumption is described. The engine can switch from a fuel to another without any modification of engine structure and systems.

These capacities are obtained by a new way to achieve fuel injection and combustion. The fuel charge of each engine cycle is divided in two portions of different amount which are injected sequentially, one in the separate combustion chamber, the other in the main combustion chamber. Both injections are achieved by the same injection pump.
