Oil-pumping and Piston Slap.

Unique Swedish Invention

NO CARBURETTOR

An engineer now resident in Stockholm has just perfected and patented the following unique sys- tem of fuel injection. The device is simple to make and is easy to fit to an ordinary engine, whilst it confers the advantages that almost any fuel can be burnt, that the engine will start from cold without difficulty, and that both the car- burettor and the vacuum feed tank become unnecessary,
