Abstract
An improved gasifier and engine system which includes an air compressor, a fixed-bed gasifier, a gas cleansing device and a diesel-cycle internal combustion engine. Ambient air is compressed by the compressor to a predetermined first pressure and is directed to a chamber of the gasifier which contains a batch loaded charge of coal and/or other expendable conditioning materials such as water, limestone and sand. The gasifier partially burns the charge and produces high pressure and temperature fuel gas which is cleaned up prior to exiting the gasifier chamber. The cleaned hot fuel gas is directed to the engine where an injection device injects the fuel gas into a combustion chamber of the engine during a later portion of a compression phase of the diesel cycle. The injected fuel gas is ignited in the engine combustion chamber by a glow plug or other ignition-assist device. The remains of the burned charge in the gasifier chamber are removed, along with the contaminated or reacted conditioning materials, and replaced by a fresh charge. The subject invention provides a feasible way of continuously fueling an internal combustion engine with gasified fossil fuel and is compact enough to…
