Design and implementation of a diesel combustion bomb facility
A combustion bomb capable of simulating diesel combustion without the need to heat the bomb to high temperatures is described. A lean precharge composed of acetylene, nitrogen, and oxygen is inducted into the bomb through a shrouded valve and burned to simulate conditions produced by the compression stroke in an actual diesel engine. By controlling the partial pressures of the precharge constituents it is possible for the burned gases to have an oxygen concentration, temperatures, and pressured similar to that of air in an engine at the time of fuel injection. Diesel fuel injected into these gases autoignites and burns in a manner typical of combustion in diesel engines. The shrouded valve can be oriented to create swirl and turbulence, which are thought to be important in diesel combustion. The combustion process can be observed through thick quartz windows which allow optical access to the entire bomb volume. Additional ports are provided for mounting a variety of probes.
