Specific embodiment
Firstly, as shown in Figs.1 and 2, a kind of dress of the utility model about changeable car engine compression ratio
Set, be installed at the top of engine ontology 1 of car engine A, further included: a first piston 3, one first crankshaft 4, one drive
Dynamic device 5.
Wherein several cylinders 2 are equipped in the engine ontology 1 to arrange, and 2, each cylinder distinguish respectively have a compression unit 21 and
One sliding part 22, wherein the compression unit 21 is in close proximity at installation cigar lighter then at the top of the cylinder 2, and the sliding
Portion 22 is then located at the lower section of the cylinder 2, and the compression unit 21 of the cylinder 2 provides and installs the first piston 3, and the cylinder 2
Sliding part 22, which then provides, installs the second piston 6.
Further, as shown in Figures 1 and 2, which sets by 32 institute of a first piston head 31 and one first interlocking lever
It constitutes, the inside of the first piston head 31 is arranged in by the bottom end of first interlocking lever 32；Similarly, which sets by one
