Technical Note:
The box volume is defined as the product of three perpendicular dimensions measured in the following way:
Length: The length of the crankshaft from front flange to flywheel face;
Width: The greatest of the following:
(a) The outside dimension from valve cover to valve cover;
(b) The dimension of the outside edges of the cylinder heads; or
(c) The diameter of the flywheel housing;
Height: The greater of the following:
(a) The dimension of the crankshaft centreline to the top plane of the valve cover (or cylinder head) plus 2 times the stroke; or
(b) The diameter of the flywheel housing.
(b) Development and production technology for solid or dry film cylinder wall lubrication permitting operation at temperatures in excess of 723K (450°C) measured on the cylinder wall at the top limit of travel of the top ring of the piston. Vessels, surface-effect vehicles, water-screw propellers and hub assemblies, water-screw propeller systems, moisture and particulate separator systems and specially designed components, as follows:
(a) Hydrofoil vessels with automatically controlled foil systems which are capable of speeds of above 40 knots in rough water (Sea State Five);
(b) Surface-effect vehicles, i.e. hovercraft, air cushion vehicles (both sidewall and skirted varieties) and all variations of vehicles using the wing-in-ground effect for positive lift;
(c) Small waterplane area twin-hull (SWATH) vessels having underwater hulls whose cross-sectional area varies along the longitudinal axis between points two major diameters from the bow and two major diameters from the stern;
Technical Note:
SWATH vessels are those which maintain buoyancy by means of submerged hulls using slender struts to support the deck and superstructure of the vessel above the waterline.
(d) Vessels incorporating:
(1) Equipment covered by any Munitions List Item, or by any of the following Items IL1485, 1501, 1502 and 1510;
(2) Degaussing facilities; or
(3) Closed/ventilation systems designed into the vessel which are designed to maintain air purity and positive pressure regardless of the conditions external to the vessel except where those closed ventilation systems are specially designed for and incorporated in the vessel's medical facilities only;
Note:
This sub-item does not apply to vessels containing equipment covered by Items IL1485, 1501, 1502 or 1510 whose export has been previously authorized.
(e) Water-screw propellers and hub assemblies, as follows:
(1) Supercavitating propellers rated as greater than 10,000 hp;
(2) Controllable-pitch propellers and hub assemblies rated at above 40,000 hp capacity;
(f) Water-screw propeller systems, as follows:
(1) Contrarotating propeller systems rated at greater than 20,000 hp,
(2) Ventilated, base-ventilated and super-ventilated propeller systems;
(3) Systems employing pre-swirl and post-swirl techniques for smoothing the flow into a propeller so as to improve propulsive efficiency of:
(i) SWATH vessels, hydrofoil vessels, and surface-effect vehicles; or
(ii) Other vessels whose propeller rotational speed is above 200 rpm, or having propellers with a rating exceeding 50,000 hp per shaft;
