Abstract
Abstract A starting system for diesel engines which sequentially provides pressured gas directly to the cylinders to initiate engine turnover. The gas is supplied either from a compressed air storage or from a chemical pressure generator capable of supplying high-pressure, high-temperature gases. The chemical pressure generator supplied gases initiate engine turnover while heating the engine to a point necessary for combustion in lowtemperature environments.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
151 words
In an auxiliary starting system for diesel engines, wherein pressured gas is ported directly to the cylinders of the engine in timed sequence corresponding to the differing positional movement of the pistons in the cylinders to force the pistons to move to turn over the engine, the improvement of a dual supply system for supplying the pressured gas, one of said supply systems supplying relatively low-temperature pressured gas, the other of said supply systems supplying high-temperature pressured gas (and the said systems separately actuatable) a distributor receiving gas from both systems delivering the gas in said timed sequence to the cylinders, means for separately actuating said systems to selectively supply the low-temperature and the hightemperature pressured gases to said distributor, a high volatile fuel source pressured from the compressed air source, and a valve selectively controlling flow of pressured fuel from said fuel source to the intake manifold of the engine.
