| 摘要 |
An internal combustion engine comprises a cylinder assembly including a cylinder (4), at least one piston (8) mounted for reciprocation within the cylinder (4), a common compression chamber (6) defined by the cylinder (4) and piston(s) (8), a plurality of prechambers (3) each having restricted communication with the common compression chamber (6), each prechamber (3) having ignition means (1) operable to ignite fuel therein and means (18) to control admission of fuel to the prechambers (3) in such a way that at any time fuel may be admitted selectively to one, some or all of the prechambers (3), allowing combustion to take place in only one or in a selected number of prechambers (3). Where more than one prechamber (3) is charged with fuel, ignition of fuel may be selected to be effected simultaneously or sequentially.
