Abstract
A pre-chamber structure for a piston engine may include: a pre-chamber combustion chamber in which a mixture of fuel and air is combusted and a pre-chamber compression chamber including a sub-chamber communicating with the pre-chamber combustion chamber and having an inclined wall surface, and a main chamber extending from the sub-chamber, thereby preventing the fuel from being adsorbed and remaining in the wall surface of the pre-chamber compression chamber in a droplet state.
Claims14
A pre-chamber structure for a piston engine, comprising:
- a pre-chamber combustion chamber configured to combust a mixture of fuel and air to spread flame to a main combustion chamber;
- and
- a pre-chamber compression chamber comprising a sub-chamber communicating with the pre-chamber combustion chamber and having an inclined wall surface, and a main chamber extending from the sub-chamber.
A pre-chamber structure for a piston engine, comprising:
- a pre-chamber combustion chamber in which a mixture of fuel and air is combusted;
- and
- a pre-chamber compression chamber comprising a sub-chamber communicating with the pre-chamber combustion chamber and having an inclined wall surface, and a main chamber extending from the sub-chamber,
- wherein an injector configured to spray fuel to the main chamber is inclinedly installed at one wall surface of the main chamber at the same inclined angle as that of an inclined wall surface of the sub-chamber,
- a piston is vertically movably installed in the main chamber, and
- a lower portion of the piston is inclined at the same inclined angle as that of an inclined wall surface of the sub-chamber.
