1956 Commer C7 MkIII TS3 2-stroke

** Courtesy of http://www.commer.org.nz ** David Kent of South Australia restored this MkIII interim. The Commer is a CD 762 meaning it originally had a lwb 162" chassis.

The Rootes TS3 (Tillings-Stevens) engine was a unique design, loosely based on the Sultzer Bros concept. The TS3 was built by Commer and first used in 1953.

What an awesome noise

[grumpyoldsoandso]

Is this one fitted with an original exhaust system? TS3 are always raucous, but this one seems exceptionally so. Perhaps an original one couldn't be obtained, and this is the result. It's delightful, anyway!

I remember the distinctive sound of the blower from my childhood days, otherwise it was a sound only from vintage cars. I was then lucky enough to own a 1968 TS3 horse box in the late 1990s, a wonderful vehicle to drive with a 6 speed gear box but only needing 5th & 6th on the flat! In addition to the distinctive noise, the engine would de-coke from time to time, alarming following motorists with a shower of sparks thrown out just in front of the rear wheel ! Most TS3s had double headlights.

@kawa7900 My father was a diesel mechanic, and even as a boy in the 70s I remember him working on Commer 2-strokes. I think they kicked out somewhere around 145 hp, though the torque was the real reason to buy one. Even now, not far from where I live, a retired driver has taken to restoring old Commer knockers. He has 2 complete and running, and a third undergoing a makeover. You can hear him coming a mile off!

The TS3 is a two-stroke opposed-piston engine with three cylinders and six pistons. It has one lower-mounted crankshaft sitting on a plane line dividing the engine longitudinally, and the pistons are connected to it using a series of levers. The arrangement allows for a very compact engine block.

Too bad the video ended right when it was sounding good!

back in the 50s/60s in Lancs UK , Bridges Express Transport ran 50 of these trucks, reason they were fast and reliable and bloody noisy to boot,

Often 20 trucks would leave the yard and race down the street, the sound was unreal!!

@Xx69roadrunnerxX The TS3 is based on the Junkers patent, 3 cylinders with the 3 pair of Pistons opposed working through rockers onto the crankshaft, basically the same principle as the Napier Deltic used in English Electric Class 55 BR locomotives.

TS3 engines have three horozontal cylinders with six pistons. 2 pistons to each cylinder.

what sort of hores power did these trucks make as they sound fantastic

The Commer Avenger coach used the same engine. I can't imagine what the passengers must have thought of a long tour with that racket.
