Abstract:
1. A diesel type cross-cycle internal combustion engine comprising: a) at least one set of a male-cylinder and a female-cylinder for performing a cross-cycle; b) a male-piston reciprocating within the male-cylinder; c) a female-piston reciprocating within the female-cylinder; d) an air-intake-valve for admission of air into the male-cylinder; e) a fuel-supplying means and a diesel-ignition means, installed on an engine head of the female-cylinder, for initiating a hot-combustion, of fuel and a cold-expansion-medium remained from an exhaust process of a previous cross-cycle, before TDC of the female-piston; f) an exhaust-port, installed on the lower portion of the female-cylinder, for effecting a direct expelling-passage in the female-cylinder when the female-piston reciprocating over the lower portion of the female-cylinder; and g) a coordinate-valve, which is a type of spring-check-valves or swing-check-valves, installed on the engine head of the female-cylinder and served as a check-valve of compressed air from the male-cylinder, for effecting an injection of compressed air which cools down a working medium, of the hot-combustion in the female-cylinder, into a cold-expansion-medium of carbon-dioxide gas, oxygen gas, and nitrogen gas, wherein:
