Title:
内燃エンジン用の気体燃料燃焼装置
Document Type and Number:
Japanese Patent JP6591994
Kind Code:
B2
Abstract:
Diesel-cycle engines are known to have greater power, torque and efficiency compared to Otto-cycle engines of like displacement. When the fuel is a gaseous fuel, such as natural gas, a pilot fuel (such as diesel) is normally required to assist with ignition in a gaseous fuelled Diesel-cycle engine. It would be advantageous to reduce the power, torque and efficiency gap between a Diesel-cycle engine and a gaseous fuelled Otto-cycle engine. A combustion apparatus for a gaseous fuelled internal combustion engine comprises a combustion chamber defined by a cylinder bore, a cylinder head and a piston reciprocating within the cylinder bore. A diameter of the cylinder bore is at least 90 mm and a ratio between the diameter and a stroke length of the piston is at most 0.95. There is at least one intake passage for delivering a charge to the combustion chamber, and at least one intake valve is configured in the cylinder head and cooperates with the intake passage to create a predominant tumble flow motion in the combustion chamber.
