    Abstract: A reciprocating compressor comprises a piston body reciprocally movably disposed within a cylinder housing and having first and second pistons which are coaxially aligned with each other. The first and second pistons define respectively first and second chambers within the cylinder housing. Intake and discharge valves are provided to allow therethrough a fluid to be sucked into and to be discharged out of each cylinder chamber, respectively. Additionally, the compressor is provided with a device for changing the rotary motion of a drive shaft into the reciprocating motion of the piston body. Accordingly, the compressor becomes small-sized and light in weight and is simplified in construction, thereby considerably reducing parts thereof.

    Abstract: A vibration suppression system for a diesel engine comprises a first device for decreasing the amount of intake air to be inducted into the engine when operated. A second device is provided to heat the intake air when operated. Additionally, a third device is provided to detect a low engine speed and low engine load operating range, and to produce a signal in response thereto. The first and second devices are operated in response to the signal from the third device, thereby avoiding irregular combustion and misfire while suppressing engine speed fluctuation and torque fluctuation.

    Abstract: An automotive internal combustion engine comprises a cylinder head having at its bottom surface two oppositely disposed projections which extend along the length of the cylinder head, and a cylinder block without an upper block deck, having two water jacket walls which are oppositely disposed to interpose therebetween a plurality of cylinder sections. The upper end part of the cylinder block fits inbetween the two projections of the cylinder head, thereby effectively preventing the cylinder block upper end part from vibrating.

    Abstract: An internal combustion engine of the reciprocating piston type, which is provided with an exhaust gas recirculation circuit to suppress the formation of NOx and has two or three spark plugs for each combustion chamber. There is a substantial overlap of the opening periods of exhaust and intake valves, so that a portion of the combustion gas is left unexhausted. The combustion chamber has a simple shape such as hemisphere, and the spark gaps of the plural spark plugs are arranged distant from each other in each combustion chamber so as to respectively share approximately equally divided portions of each combustion chamber. The number of the spark plugs is two when the volume of the recirculated exhaust gas, including the unexhausted combustion gas, is about 50% at the maximum of the volume of air admitted into the combustion chamber but three when the recirculated exhaust gas amounts to about 60% of the air at the maximum.
