摘要： PURPOSE:To improve the sealing ability by providing a groove portion on the outer periphery of an insulator or forming the inner periphery like a projected surface. CONSTITUTION:An insulator 88 is installed on an annular groove 86 of the outer periphery of an injector. The insulator 88 has a gap (w) to the opposed inner surface of an injector install hole and a groove 99 having a V-shaped section on the outer periphery thereof, so that the insulator is made flexible by the groove 99 and in the case of installing the injector 17 with a gradient, the insulator follows it to be deformed. Thus, sealing is ensured. The insulator 88 has a projected surface 101 in the inner periphery and is brought into close contact with the bottom surface 86A of the seal install groove 86 so that sealing is also accomplished in this portion.

摘要： PURPOSE:To prevent freezing of an air assist hole by accumulating water drops on this side of the air assist hole. CONSTITUTION:An air gallery 110 is formed in a solid wall surface portion of an intake manihold 12. The air gallery 110 is communicated with an assist air chamber 105 of each cylinder through an opening portion 114. The assist air chamber 105 is adapted to air-assist to a fuel flow from a nozzle hole 74 of an injector 17 through an air assist hole 107. The air gallery 110 is connected to ISC valve to supply the assist air. An opening portion 114 of the air gallery 110 to the assist air chamber 105 is positioned above the bottom surface 110A of the air gallery 110, so that water drops of the air assist system at the time of stopping an engine are captured on the bottom surface of the air gallery 110 not to reach the assist air chamber 105. Accordingly, freezing of the air assist hole 107 can be prevented.

摘要： PURPOSE:To effectively cool a bearing and improve durability of a turbocharger with its functional capability being retained, by providing to a center housing a water jacket which passes transversely across the upper portion of turbine shaft. CONSTITUTION:A water jacket 19 is formed to pass transversely across an upper portion of a turbine shaft 2, having a water inlet formed at a portion thereof as high as the shaft 2 and a water outlet 21 formed at an opposite side of the inlet. A presence of an oil inlet 15 causes the water jacket 19 to have its longitudinal cross-section unilaterally biased toward a turbine 1 side. In a region outside the oil inlet 15, however, the water jacket 19 has its lateral cross-section formed generally along an entire length of the center housing 10 as shown in a dotted line in such a segmental configuration in a fan shape excluding an oil passage 18a spreaded below the turbine shaft 2 like a trough.
