spark plug

1. 1.

   The part of some internal combustion engines which forms a high-voltage electric spark which ignites the fuel-air mixture to begin the power stroke. (Petrol engines have spark plugs. Diesel engines do not have them because the heat from their high compression ratios supplies the ignition.)

   某些内燃机中产生高压电火花以点燃燃料空气混合物、开始动力冲程的部件；汽油机有,柴油机因高压缩比自燃而无

2. 2.

   Someone who is a driving force in new endeavours.

   推动新事业的人

3. 3.

   A rod (for cylindrical secondaries) or sphere (for spherical secondaries) of fissile material at the center of the secondary of a multistage thermonuclear weapon, which undergoes nuclear fission when compressed to supercriticality by the imploding secondary, helping to raise the secondary to the pressures and temperatures necessary to ignite nuclear fusion in the secondary's fusion fuel.
