Premixed charge compression ignition engine and reciprocating generator having the same

A premixed charge compression ignition (PCCI) reciprocating generator having a PCCI engine structure to compress a premixed charge of fuel and air at a high temperature and a high pressure, and thus, induce a natural ignition of the premixed charge, the PCCI reciprocating generator comprising:

• a suction port provided with a suction valve;
• an exhaust port provided with an exhaust valve;
• a suction manifold placed to communicate with the suction port and provided with an injector, thus homogeneously mixing the fuel with the air therein to provide the premixed charge;
• a cooling nozzle provided at an upper end in a combustion chamber of a cylinder;
• a fluid feed pump to feed a cooling fluid to the cooling nozzle at a high pressure;
• a storage tank to store the cooling fluid therein, so that the cooling nozzle injects the cooling fluid into the combustion chamber at a high pressure during a compression stroke of a piston in the cylinder, thus providing a high compression ratio to induce the natural ignition of the premixed charge;
• and
• a reciprocating generator unit to generate electricity using a reciprocating force of the piston.

A premixed charge compression ignition (PCCI) engine to compress a premixed charge of fuel and air at a high temperature and a high pressure, and thus, induce a natural ignition of the premixed charge, the PCCI engine comprising:

• a combustion chamber provided at a sidewall thereof with both a suction port having a suction valve and an exhaust port having an exhaust valve;
• a suction manifold coupled to the suction port and having an injector therein;
• and
• first and second pistons respectively arranged in lower and upper parts in the combustion chamber to face each other, so that the first and second pistons reciprocate in opposite directions based on the combustion chamber.
