Title:
ADIABATIC INSULATED DIESEL ENGINE, AND HIGHLY EFFICIENT GENERATOR ENGINE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/145758
Kind Code:
A1
Abstract:
The present invention relates to an adiabatic insulated diesel engine, and to a highly efficient generator engine using same, which are capable of preventing adiabatic insulating material of the adiabatic insulated diesel engine from being burnt or damaged, enabling fuel to be easily ignited, and converting most of the calorific power from combusted fuel into driving power. The diesel engine comprises: a piston consisting of a piston head coated with an adiabatic insulating material, and a skirt having only a piston ring installed thereon and not coated with an adiabatic insulating material; a cylinder, an inner wall region of which, in which the piston head reciprocates, is coated with an adiabatic insulating material; and a cylinder head including an exhaust valve and an exhaust passage, on the inner surface of which an adiabatic insulating material is coated, which is coupled to the top portion of the cylinder, and which forms a sealed, adiabatic insulated chamber together with the wall of the cylinder coated with adiabatic insulating material and the piston head coated with the adiabatic insulating material. A small cylindrical combustion chamber, the diameter of which is smaller than those of the inner cavity of the cylinder and of the piston head, and the volume of which is 1/20th to 1/200th of the volumetric expansion of the adiabatic insulated chamber, is defined in the cylinder head. A compressed air passage and an intake valve, for introducing compressed air into the small combustion chamber during an exhaust cycle, are also defined in the cylinder head. An injector, for injecting fuel and water at certain time intervals into the compressed air introduced into the small combustion chamber, is installed on the cylinder head.
