A pneumatic tire and a rim includes a noise damper, fixed to a tire inner surface or a rim inner surface with the upper surface facing a tire inner space, and extending in the tire circumferential direction. The noise damper is made of a sponge having a volume ranging from 0.4 to 20% of the volume of the tire inner space. The noise damper is a laterally long and flat, with a maximum thickness ranging from 5 to 45 mm and a width more than the maximum thickness. The upper surface extends along a wavy curve including a hilltop, valley bottoms on each side of the hilltop and slopes extending down to the respective valley bottoms from the hilltop. Each end of the upper surface is terminated at the valley bottoms or the slopes. A thickness from the upper surface to the bottom surface ranges from 1.0 to 15.0 mm.

An assembly of a pneumatic tire and a rim includes a band-like noise damper, having the bottom surface fixed to a tire inner surface or a rim inner surface and the upper surface facing a tire inner space in the tire inner space, and extending in the tire circumferential direction. The noise damper is made of a sponge having a volume in the range of from 0.4 to 20% of the entire volume of the tire inner space. In a tire meridian section, the noise damper is of a laterally long, flat sectional shape having a maximum thickness value (tm) from the bottom surface to the upper surface in the range of from 5 to 45 mm and having a width (W1) of the bottom surface more than the maximum thickness value (tm). The upper surface extends along a wavy curve that is repetition of a wavy element in the width direction including a hill top portion having the maximum thickness value (tm), valley bottom portions on each side of the hill top portion having the minimum thickness value (ti) and slope portions extending down to the respective valley bottom portions from the hill top portion. Each end in the width direction of the upper surface is terminated at the valley bottom portions or the slope portions, but a thickness (te) from the upper surface to the bottom surface is in the range of from 1.0 to 15.0 mm.

摘要:
An intake port (4) is connected to a combustion chamber (6) of an internal combustion engine (1) via an intake valve (15), and a volatile liquid fuel is injected from a fuel injector (21) provided in the intake port (4). The controller (31) calculates a suspension ratio in the combustion chamber (5) of the injected fuel according to the particle diameter of the injected fuel (52-56), calculates an amount of fuel burnt in the combustion chamber (6) based on the suspension ratio (57), calculates a target fuel injection amount based on the burnt fuel amount (75, 76), and controls a fuel injection amount of the fuel injector (21) based on the target fuel injection amount (76). Precise fuel injection control can be performed without performing adaptation experiments, based on particle diameter data for different fuel injectors by taking the particle diameter as a parameter.
