    Abstract: The external profile of a piston rod employed in the engines of passenger cars ensures smoother piston travel on start-up and during partial loading. In these operating ranges, piston ring parts may impact on the sliding surface of the cylinder on the counter-pressure side and give rise, amongst others things, to undesirable noise. To obviate such impacts, the piston rod tapers at the end facing the crankshaft space on the counter-pressure side, and has a transversal slit (3) at its junction with the piston head and an adjustment strip (4) in the vicinity of the said slit. An additional adjustable strip (5) may also be provided in the lower part of the rod, on the pressure side. As a result of the position of the adjustment strips, the special design of the piston and the special shape of the rod casing, the piston head aligns itself at a slight angle to the counter-pressure side, with increasing play between the piston head and the sliding surface of the cylinder, in the said operating ranges. When the engine is running at full load, the piston head realigns itself in the direction of its axis.

    Abstract: The technical problem is to reduce the operating noise of such a piston. It is solved by means of a piston having the following dimensions: a) A = (0.45-0.65) D; b) H = (0.25-0.4) D; c) A = (0.3-0.4) D; d) A greater than or equal to B; e) T = (0.45-0.8) D; f) the piston ribs between the annular grooves (2, 3, 4) and the rod region with a very narrow operating clearance have, in the case of a hot operating piston, approximately the same clearance in relation to the cylinder operating path. An additional improvement consists in inserting an annular jacket in the piston head in the radial region behind the annular grooves, said jacket consisting of a material having a thermal expansion factor less than that of the basic piston material. In a hot operating internal combustion engine, the piston has, in the region of the ribs, a clearance which, in the direction pressure/counter-pressure reaches approximately only 3-5 times the clearance in the very narrow clearance region of the piston rod.

    Abstract: Aluminium-based article having a heat and corrosion protective coating, especially engine parts such as piston crown or cylinder head, and a method of preparing said article. The coating consists of an aluminium-based bonding layer, preferably having a thickness in the range 0.1-0.6 mm, and an outer top layer of stabilized or partially stabilized zirconium dioxide, preferably having a thickness in the range 0.5-2.5 mm, and optionally a cermet layer, comprising zirconium dioxide and an aluminium-based metal component, between the bonding layer and the outer zirconium dioxide top layer. The bonding layer is applied to the substrate by thermal spraying of a rapidly solidified powder, substantially consisting of 60-80% by weight of Al and 40-20% by weight of Si, the particles of the powder having a frozen unstable micro-structure. The cermet layer desirably is a layer consisting of zirconium dioxide and an aluminium-based alloy, the metal content of the cermet layer decreasing substantially uniformly in the direction towards the outer zirconium dioxide top layer. The cermet layer preferably has a thickness in the range 0.2-0.6 mm. Also the cermet and zirconium oxide layers are deposited by thermal spraying.

    Abstract: An internal combustion engine comprises a flow control device (6), for controlling the flow of petroleum fuel into the engine, and which comprises regulator elements (18, 19), the relative positions between which controlling the flow rate, the positions of the regulator elements being controlled by an input element (23). The device comprises an adjustment means (30) which can be set to a number of different values, which provide for different response rates of the regulator elements (18, 19) to movement of the input element (23). Liquid fuel is thus injected at a desired rate into a stream of air, utilising a closure member (66) which when the pressure at which fuel is delivered to an outlet nozzle (51) is less than a predetermined value, prevents flow of fuel through the outlet nozzle, and when the pressure at which fuel is delivered to the outlet nozzle exceeds said predetermined value, the closure member moves to open the outlet a distance proportional to the pressure in the outlet nozzle. The engine also comprises a cylinder (110) and a piston (112) slidably mounted in the cylinder. The piston (112) is provided with a cooling passageway (122) which at or adjacent the bottom dead centre position of the piston is aligned with inlet and outlet ports (124, 126) of the cylinder. In the use of the engine, gas, which may be air or a mixture of fuel and air, is caused to flow through the cooling passageway during part at least of the cycle of reciprocation of the piston in the cylinder, to remove heat from the piston (112).
