摘要： PURPOSE:To accelerate the activation of a catalyst as well as to aim at the simplification of a device in terms of structure and the promotion of low-unit cost of production by igniting a burner simultaneously with engine starting, thereby heating the catalyst, and when a catalytic temperature has become more than the specified value, stopping a combustion of the burner. CONSTITUTION:An exhaust emission control device is provided with a catalytic chamber 12 set up in an exhaust pipe 10 and a burner 14 being installed in close proximity to the upstream of this catalytic chamber 12 and ignited simultaneously with the start of an engine 38. In addition, it is also provided with a branch pipe 18 being branched off from a fuel feed pipe 16 and feeding the burner 14 with fuel, an air blower 20 for feeding the burner 14 with air from the time of igniting the burner 14, a temperature detector 22 detecting a catalyst temperature, and a car-mounted electronic control unit 24, respectively. In this constitution, the burner 14 is ignited simultaneously with engine starting, heating the catalyst as specified, and when the catalytic temperature has become more than the specified value, the burner combustion is stopped. Thus, activation in the catalyst is accelerated, whereby simplification in this device and low-unit cost production are all well promotable.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure of resin-made parts which are formed before welding by injection molding with an identical thickness, normally using the same material and can be easily joined together, even when the parts are easily deformed by an adverse effect of an inverted blister and a warpage is generated on the joint faces 22a and 23a which are easily subjected to it after molding. SOLUTION: In the joint structure, of the resin-made parts 22 and 23, which join the joint faces 22a and 23a formed on a plurality of the resin-made parts 22 and 23 respectively by superposing the parts, the rigidity of each of the parts in an orthogonal direction with the joint faces 22a and 23a is increased in one part 23 and decreased in the other part 22. The difference of the rigidity can be imparted by differentiating the thicknesses A and B of the parts or reinforcing ribs or the material or the shape.

摘要： PROBLEM TO BE SOLVED: To provide an intake air surge tank of an internal combustion engine constituted so as to enhance rigidity without increasing weight and a manufacturing cost. SOLUTION: This synthetic resin intake air surge tank 13 is arranged between a throttle valve 14 of the internal combustion engine and an intake air port of a combustion chamber 7, and is characterized by having an opening 16 closed by a lid 17 formed of a construction material having the rigidity higher than the surge tank. Thus, since only a relatively easily deformable planar part can be selectively formed of a highly rigid material, deformation can be highly efficiently restrained.

摘要： PROBLEM TO BE SOLVED: To improve a surge tank so as to relatively easily secure seal performance of a bolt fastening part inserted from the inside of the surge tank in fastening the synthetic resin surge tank by bolts to an intake air manifold (an engine body). SOLUTION: This intake air surge tank 13 of an internal combustion engine is formed of a synthetic resin material, and is joined to one end of the intake air manifold 5 by gathering a plurality of intake air passages 10 having other end joined to cylinder heads 3a and 3b. It is characterized in that passage holes 21 individually continuing with the respective intake air passages and bolt inserting holes 22 for mutually fixing the surge tank and the intake air manifold are opened in joining planes of the surface tank and the other end surface of the intake air manifold, and a seal member is installed along the outer peripheral edge of the joining planes so as to surround the periphery of the passage holes as well as to surround the outside of the bolt inserting holes. Thus, since the periphery of the respectively passage holes and the periphery of a plurality of bolt inserting holes are collectively and simultaneously sealed without using a metal gasket, even if the bolts are inserted from the inside of the surge tank, leakage of negative pressure from a clearance between the bolt inserting holes and the bolts is prevented.
