Title:
INTERNALLY COOLED HIGH COMPRESSION LEAN-BURNING INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2017194065
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture, allowing more complete and efficient combustion and therefore better thermal efficiency compared to conventional engines.SOLUTION: An internally cooled internal combustion piston engine and a method of operating the piston engine are provided with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. An effective compression ratio of the engines is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to a radiator, reduces engine knock, and reduces NOx emissions.SELECTED DRAWING: Figure 3
