Being chased? With our options we can create a smoke screen/cloud to be installed on your vehicle through a smoke generator. This machine heats a volatile material (typically oil or an oil based mixture) to evaporate it, then mixes the vapor with cool external air at a controlled rate so it condenses to a mist with a controlled droplet size.
Many armoured vehicles can create smoke screens in a similar way, generally by injecting diesel fuel onto the hot exhaust. See other options here.
