Abstract: 【課題】熱効率を向上する内燃機関を提供する。【解決手段】燃焼室22を形成するピストン30のピストン面31には帯電可能な絶縁膜32が形成されている。排気行程から吸気行程にかけてシリンダヘッド部24に設けられている電界形成電極35に高い正電圧が印加されると、絶縁膜32は正に帯電する。燃焼行程において燃焼室22で生成される火炎は正極の性質を有するため、正に帯電している絶縁膜32と反発しピストン面31から離れる。これにより、ピストン30を介して外部に放出される火炎の燃焼熱が少なくなる。したがって、エンジン1における冷却損失を低減することができる。【選択図】図2

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust gas treatment device of a hybrid system without deteriorating fuel efficiency, by dispensing with maintenance of the temperature.SOLUTION: NOx, HC, and CO held in a gas storage part 23 and PM held by a PF22 are oxidized or reduced by reacting with an oxidizing agent and a reducing agent included in exhaust gas by plasma and an electromagnetic wave generated by electric power supplied from a battery 16 when an engine 11 stops operation. At this time, though the PF22 and the gas storage part 23 are indirectly heated by reduction reaction of the NOx or oxidation reaction of the PM and the HC, the whole is not directly heated by the electric power from the battery 16. Thus, energy required for oxidation of the PM and the HC or reduction of the NOx is reduced. Thus, a specific substance discharged from the engine 11 can be treated without deteriorating the fuel efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control device evenly heating a particle collecting part, reducing melting of the particle collecting part, and capable of carrying out regeneration of the particle collecting part even when a single high frequency irradiation part is used.
SOLUTION: The exhaust emission control device 10 has a turbine 16 and a stepped part 23 reflecting a microwave irradiated from the high frequency irradiation part 13 to a side of the particle collecting part 12. A blade surface 28 of the turbine 16 is inclined with respect to a center axis of an exhaust passage 14. By this, when the turbine 16 is rotated, a position of the blade surface 28 reflecting microwaves irradiated from the high frequency irradiation part 13 is changed. Thereby, when the turbine 16 is rotated, microwaves reflected by the turbine 16 is changed in propagation length, and a phase in the particle collecting part 12 is changed. As a result, a portion wherein electric fields of the microwaves reflected by the turbine 16 are concentrated is moved with respect to the particle collecting part 12 following rotation of the turbine 16. By this, the microwaves are evenly irradiated with respect to the particle collecting part 12.

Abstract: PROBLEM TO BE SOLVED: To provide a gas adsorption amount sensor for precisely detecting the adsorption amount of the adsorption target gas adsorbed by a gas-adsorbing member.
SOLUTION: The sensor section 21 of the gas adsorption amount sensor 14 has a sensor adsorption section that includes zeolite which is a material identical to that of the adsorption layer of a catalyst 12. Accordingly, the sensor adsorption section adsorbs ammonia being the adsorption target gas in the same way as the adsorption layer of the catalyst 12. That is, the adsorption characteristics of ammonia in the sensor adsorption section are substantially identical to the adsorption characteristics of ammonia in the adsorption layer of the catalyst 12. As a result, the adsorption amount of ammonia on the sensor adsorption section becomes substantially identical to that of the adsorption amount of ammonia of the catalyst 12 itself. According to this constitution, the adsorption amount of ammonia in the sensor adsorption layer can be regarded in the same light as with the adsorption amount of ammonia on the adsorption layer of the catalyst 12. hence, the adsorption amount of ammonia adsorbed by the adsorption layer of the catalyst 12 can be accurately detected using the gas adsorption amount sensor 14.
