摘要： In the operation of a diesel engine, a mixture of air and fuel is flowed into each cylinder during the intake stroke when air alone normally would be flowed in. However, the mixture is lean so it does not ignite as the mixture is compressed and heated. Sufficient additional fuel is injected into the cylinder near the top of the compression stroke to increase the amount of fuel so the hot mixture ignites. As a result, most of the air and fuel has intimately mixed prior to ignition.
摘要翻译：在柴油发动机的运行中，空气和燃料的混合物在进气冲程期间流入每个气缸，当单独的空气通常将流入时。然而，混合物是稀的，因此当混合物被压缩和加热时它不会点燃。在压缩行程顶部附近有足够的额外燃料喷射到汽缸中，以增加热混合物点燃的燃料量。结果，大多数空气和燃料在点燃之前已经充分混合。

摘要： A method is provided for operating an internal combustion engine comprising a combustion chamber defined by the inner wall of a cylinder, a cylinder head and the upper surface of a piston moveable longitudinally within the cylinder, the engine further comprising a pre-combustion chamber in communication with the combustion chamber. The method comprises supplying to the combustion chamber a first combustible mixture of a first hydrocarbon fuel and oxygen; supplying to the pre-combustion chamber a second combustible mixture of a second hydrocarbon fuel and oxygen, the second combustible mixture being auto-ignitable; and compressing the first and second combustible mixtures by moving the piston within the cylinder; wherein under operating conditions in which the aforementioned steps are insufficient to operate the engine and keep it running, the method further comprises the step of generating a spark to cause ignition of the compressed first combustible mixture in the combustion chamber. An internal combustion engine operable using this method is also provided. In addition, a cylinder head for the modification of existing engines to operate using this method is also provided. The method is particularly useful for starting the internal combustion engine, especially when cold.
