The volume determining the compression ratio is formed by a combustion antechamber (8) and a chamber (4) over the piston and a further air chamber (14) storing the air required by the antechamber. The air chamber and antechamber are permanently connected by a passage (12), connected at regular intervals via a slot (17) to the air chamber. A plug (15) alternately shuts off the slot and the drilling (13) connecting the air chamber to the main chamber. A poppet valve (6) controls admission of fuel from a vaporising chamber (7). A further valve (9) controls admission of gas through a further passage (10). A vaporiser (24) heated by the exhaust manifold (25) may gasify liquid fuels. On the compression stroke air passes up the passage into the antechamber, diluting the rich mixture contained in it. During the power stroke, air from the air chamber scavenges the combustion chamber. |
