In the bombardier beetle, the muscles that prevent leakage from the reservoir additionally developed a valve permitting more controlled discharge of the poison and an elongated abdomen to permit better control over the direction of discharge. [11] [12]
Hydroquinones are one of the two primary reagents in the defensive glands of bombardier beetles, along with hydrogen peroxide (and perhaps other compounds, depending on the species), which collect in a reservoir. The reservoir opens through a muscle-controlled valve onto a thick-walled reaction chamber.
The 16 valve Volkswagen engine is the same as the EA827 series, the only difference being the addition of piston cooling oil squirters, similar to the g60 block but with a 16 valve cylinder head attached.

The False Bombardier Beetle ranges from 14.9 to 20.0 mm long and is bodily and bilaterally symmetric. These beetles are mostly black, with a red/orange color displayed on their thorax and legs. They are known for having a unique defense mechanism, which consists of spraying out fluid from an abdominal gland when threatened. [6]
These beetles, along with others in the subfamily Paussinae, are known as flanged bombardier beetles due to their ability to explosively discharge benzoquinones, chemical irritants, at temperatures between 55° and 100 °C. A flange on their elytra assists in directing the chemicals toward the front of their bodies.
The bombardier beetle is unusual by using a violent exothermic chemical reaction to launch a boiling noxious chemical spray in a rapid burst of pulses from special glands in its abdomen, accompanied with a popping sound. The Anthia (oogpister beetle) will fire formic acid at
