I think it should be possible to approximate the desired effect by modifying the particle size. Anyhow, it feels a little bit like a workaround (particles are constantly emitted, just not visible or very small). IMHO the most suitable and intuitive property for the afterburner example and similar use cases would be the emissionRate.
For now I’ll try the suggested solution. Thanks and Goodbye,
