摘要： PURPOSE:To reduce a length of a connecting rod compared to a stroke length and reduce the height of an engine by forming a recession on a lower portion of a cylinder so as to prevent occurrence of interference. CONSTITUTION:An upper piston 1 and a lower piston 2 which are provided on a rod 4 are connected to a crank shaft 6 by means of a connecting rod 5. A slit 8a having a width a little larger than the thickness of the connecting rod 5 are formed on a cylinder liner 8 to which the lower piston 2 is abutted within a range of crank angle between 90 and 270 degrees, while a recession 7a is formed on a cylinder 7. The recession 7a and the slit 8a prevent occurrence of interference of the connecting rod 5. It is therefore possible to reduce the length of the connecting rod compared to a stroke length, and reduce the height of the engine.

摘要： PURPOSE:To reduce fuel consumption through reduction of engine vibration and engine weight by providing a structure where the center of a rotor, a rotating body and the center of a rotor housing, a rotated body coincide. CONSTITUTION:A reciprocating piston C is incorporated in a rotor B which moves along an inner wall of a rotor housing A which is concentric with the rotor, and is connected to a connecting rod D. A crank shaft E, a rotating body with its center at an eccentric position from the center of the rotor housing A is connected to the connecting rod D. One or more piston (s) C can be provided. In the above-mentioned condition, reciprocating motion is generated in the piston C by rotating the rotor B and the connecting rod D within the rotor housing A at a same speed. By utilizing this motion, strokes of intake, compression, explosion and exhaust can be achieved with a unit of 720 degrees by operating an intake valve and an exhaust valve. This allows reduction of fuel consumption through reduction of engine vibration, increased torque, motion resistance and engine weight.

摘要： PURPOSE:To improve lubrication and sliding characteristics or obtain similar improvements by forming a cylinder liner and each type of bearings respectively with a ceramic material, and providing an alcohol injector or the like in an air intake passage for introducing the intake air into a crank chamber. CONSTITUTION:A cylinder liner 4 comprising a ceramic material is coupled to a cylinder 23 formed as part of a cylinder block 6. On the other hand, a ball bearing 1 comprising a ceramic material is assembled into a space between a hole 30 formed in the boss 29 of a piston 29 and a piston 17. Also, a roller bearing 15 comprising a ceramic material is assembled into a space between a hole 31 formed in the large diameter part 40 of a connecting rod 25 and a crankpin 19. Furthermore, many air intake ports 20 are radially formed at the lower part of the cylinder liner 4. Also, an alcohol injector 11 is provided in the second air intake passage 39 for introducing the intake air into a crank chamber 12.

摘要： PURPOSE:To improve the intake efficiency and the like by adopting such methods as to form a combustion chamber with adiabatic construction, and to connect a supercharger to an intake passage which is communicated with a guide scroll formed at the outer circumference of a cylinder liner. CONSTITUTION:An exhaust valve 1 is arranged at a cylinder head 3, and the valve face is engaged on disengaged with/from a valve seat 19. A plurality of intake ports 12 are formed at the lower part of a cylinder liner 9 in the circumferential direction. With the intake port 12, a guide scroll 11 formed as an annular intake passage 17 at a cylinder block 4 is communicated. A turbo charger 2 which is for instance a supercharger is connected to the guide scroll 11. In upper structure of a combustion chamber 8, a head liner 5 of integrated structure is formed of a cylinder head down-face part 6 and a cylinder liner up-part 7 made from ceramic material, and is fitted to the cylinder head down-face part 6.

摘要： PURPOSE:To constantly and effectively vaporize an alcohol fuel in all the operating regions of an engine and to improve the combustion efficiency by disposing a red heat member in an internal wall portion of a combustion chamber, and controlling the red heat member so as to put to a heated or non-heated state in accordance with the operating state of the engine. CONSTITUTION:A sub-combustion chamber 5 in which an exhaust valve 1 and an alcohol fuel injection nozzle 15 are respectively disposed has upper and lower internal wall portions 26, 29 made of material of low thermal conductivity. A red heat plate 12 is provided between the upper and lower internal wall portions 26, 29 and an outer periphery thereof is thermally insulated from a cylinder head 3 through a heat insulating gasket 14. Then, the driving of the fuel injection pump 11 of the fuel injection nozzle 15 and the red heat plate 12 is controlled by a controller 10 based on respective detecting signals from an engine load sensor 16 and a rotation sensor 17. Namely, for example, when an engine speed is lower than a prescribed value, it is judged that the red heat member is put to a low temperature state and the red heat plate 12 is heated to promote the vaporization of alcohol fuel.
