Phil Dixon’s Commer “knocker”. This truck was designed with a unique opposed piston engine The engine was the first diesel developed by the London-based Rootes Group and the opposed-piston design was intended to allow the engine to fit under the seat of cab-over-engine trucks designed by company, dispensing with the bonnet or hood.

The Commer TS3 “knocker” is a unique opposed piston engine and it Sounds Good! The three-cylinder, six-piston, rocker drive two-stroke with a blower for scavenging makes an incredible noise, as evidenced by this clip from goodwinmadhouse on YouTube. A 105 hp and 270 ft-lb of torque diesel in the 50s and 60s! Quite a feat of engineering. Watch this video above (maybe a couple times) and tell us: does the Commer Knocker Sound Good?
