Title: Elevation of thermal efficiency of internal combustion engine and internal combustion engine thereof
Inventor: SHINBA MICHIO
IPC: F01K23/06
Filed: 1981-08-05
Abstract: PURPOSE:To increase the effective total heat energy by recovering the waste heat  energy in high efficiency. By means of a water tank for recovering the waste heat  installed in the manifold as well as on the muffler of an internal combustion engine  and driving a turbine by thus generated steam and adding said driving power to the  shaft output of the engine. CONSTITUTION:When the operation of an engine is continued, each pressure in a steam  collector 32 and in the steam chamber 16 of the waste heat recovery part RI increases  above a prescribed set value P1. Therefore, a pressurized flow-rate control valve 48 is  released, and a turbine 44 is driven. At this time, the steam in the steam chamber 16  passes through an excessively heating pipe 20 and forms the excessively heated steam,  which is supplied into the turbine. In this state, a power connecting apparatus is in the  connected state, and the shaft output of the turbine 44 is added to the shaft output of  an internal combustion engine 10. As the set pressure P1 is so determined as the number of revolution of the turbine 44 exceeds the max. number of revolution of the  internal combustion of the internal combustion engine, the generated horsepower and  the torque of the turbine are added to each original value of the internal combustion engine 10, and thus the total output can be increased.

Patent JP-H01293201-A (JP)
Title: Wheel
Inventor: MATSUI ISAO
IPC: B60B21/12
Filed: 1988-05-19
Abstract: PURPOSE:To improve a ride feeling by providing the directional element having the small air flow resistance from the inside of a tire to that of a disk and the large air flow resistance in the reverse direction between the air chamber of the hollow disk having a monocock structure and the air chamber of the fire in the wheel of an automobile etc. CONSTITUTION:The air chamber 4 within a tire and the air chamber 1 of the hollow disk having a monocock structure are communicated with a directional element 5. The element 5 is formed so that the flow resistance of the air from the chamber 4 of the tire to the chamber 1 of the hollow disk is small and the resistance of the flow in the reverse direction is large. In this constitution, when a tire 3 receives a shock during the travel of an automobile, the air pressure of the tire becomes high and the air passes the element 5 to flow into the chamber 1 in a small resistance. When the tire inner pressure returns to an original pressure with the shock gone and the air returns to the chamber 4 from the chamber 1, the shock is absorbed since the air gradually returns by the large resistance. Consequently a ride feeling can be improved.
