後者就是所謂的柴油引擎啦...
"Compression Ignition Engines. With a sufficiently high
compression ratio and a suitable fuel, autoignition occurs
in a reciprocating engine. The engine is similar to the spark
ignited engines described above except that during the compression
stroke, only air is taken into the piston and compressed to
ignition conditions and then, the fuel is atomized directly into
the combustion chamber at a controlled rate."
