  Cylinder liners are simple cylindrical shapes flanged at the top end to provide location and secure them in the cylinder block.   The lower end of the liner is fitted with rubber rings so as to form a seal for the bottom of the water spaces.   The sealing rings are designed to prevent scavenge air entering the water spaces.   The bore surface of the cylinder liner is slightly rough in order to retain the oil and to promote rapid wear in.   In order to provide a harder wearing surface, the bore of liners is subjected to the process of nitriding. Expressing the PURPOSE STUDY and TRANSLATE the following sentences:

In these sentences the purpose is expressed by using: to + verb (infinitive form)   to provide location so as to + verb (infinitive form)   so as to form a seal in order to + verb (infinitive form)   in order to retain the oil

Example: Studs should be evenly tightened. They must provide a satisfactory joint.  Studs should be evenly tightened (in order) to provide a satisfactory joint. Exercise 1 Link the following pairs of sentences so that they express purpose. Omit all unnecessary items:

a) a) The inner wall of the cylinder liner is porous. It should provide an oil retaining surface. b) b) A thin layer of lead or indium is often added to the main bearing shells. The layer gives protection against corrosion. c) c) Efficient scavenging is essential. It is designed to ensure sufficient supply of fresh air for combustion. d) d) The diesel oil supply system uses a transfer pump. It is fitted with the purpose of drawing oil from the double bottom tanks. Exercise 1 Link the following pairs of sentences so that they express purpose. Omit all unnecessary items:

e) e) The viscosity regulator controls fuel oil temperature. The device must provide oil at the correct viscosity for combustion. f) f) When distant pieces are fitted under the crosshead bearings they must be of exactly the same thickness. Accuracy is required with purpose of ensuring the correct alignment of the connecting rod. g) g) The connecting rod is usually forged from alloy steel, frequently with an “I“ or “channel“ section. This shape permits giving the greatest stiffness for its weight. h) h) Connecting rods sometimes taper slightly from the bottom to the top of the shank. The tapering is aimed at increasing the resistance to the bending stresses.

  Pistons may be made in aluminium alloy so that they can keep the weight down for the balancing purposes at high speed.   The rings have the gap so that they can be easily assembled on the piston.   The wall pressure of simple ring is restricted by the radial depth of the ring, in order that it may be assembled in the groove.   Send the letter by express mail in order that she gets it before Wednesday. Expressing the PURPOSE STUDY and TRANSLATE the following sentences:

In these sentences the purpose is expressed by using: so that + clause (subject + verb...)   so that they can keep the weight down... in order that + clause (subject + verb...)   in order that it may be assembled in the groove. More similar examples:  A fan was fitted at the entrance so that ventilation could be facilitated.  The piston was removed in order that it might be inspected for wear and cracks. Note: IN ORDER THAT is mostly used in formal English. In an informal style, we use SO THAT.

Example: Liners are always made of special cast iron. This enables them to resist the abrasive action of piston rings.   Cylinder liners are always made of special cast iron so that they can resist the abrasive action of the piston rings.   Cylinder liners are always made of special cast iron in order that they may resist the abrasive action of the piston rings.

o oThe research is aimed at finding solutions to this issue. o oFor this purpose the top of the piston crown may be bowl or toroidal shaped. o oFor propulsion purposes, close governing is not essential and stability is more important. o oFor obtaining the best results it is necessary that workers are well paid. ( = To obtain the best results… ) o oThe purpose (aim, object) of this report is to ensure the basic safety in the engine room. o oWhat is the purpose of supercharging? o oThe object of this design is to maintain more accurately the axial dimensions of the ring. Expressing the PURPOSE by using other words or groups of words:

1. 1.Piston rings are used in grooves turned in piston. Their purpose is to seal the gases in the top of the cylinder and prevent their leakage down the sides of the piston The engineers worked hard for two days. Their intention was to repair the damage before sailing In the fuel-supply system of larger vessels remote-operated valves are included. So, the fuel is turned off in the accidental occurrence of dangerous leaks, fires or other hazards In addition to special portable power tools, much improved workshop machinery is now provided. This enables a wider spectrum of repair work to be undertaken on board. Exercise 3 Join the sentences. Omit all unnecessary items:

5. 5.In the first port the newly-arrived rating bought a small camera. His purpose was to take as many snapshots as possible during the voyage The lower end of the cylinder liner is fitted with rubber rings. Their purpose is to provide seal for the bottom of the water space I sent my proposal to the Department Manager a week ago. I wanted him to consider them long enough before our meeting Scraper ring are generally fitted near the bottom of the trunk pistons. The oil thrown by revolving cranks is scraped off the cylinder wall on the down stroke A distance piece is interposed between the foot and the box. It permits piston to be moved nearer to or farther from the cylinder head at the top dead centre.
