HILLMAN CAR CLUB OF SOUTH AUSTRALIA INC
It has a 3 cylinder engine made by Tilling Stevens – hence the model name "TS3."
A two-stroke diesel with direct injection, there are 3 horizontal cylinders, each containing 2
pistons that are opposed to each other and almost meet in the middle. With two-stroke design,
there is no need for a cylinder head. With diesel design, there is no need for spark plugs.
The Roots (not Rootes) blower fitted to the front of the engine supplies air to the cylinders under pressure.
