engine cooling system

Voorbeeldzinnen

1. COOLING SYSTEM: LIQUID/AIR COOLING [2] For the engine representative of the type to be approved, a complete data-set shall be supplied.
2. Start the sample pumps (except the particulate sample pump(s), the engine cooling fan(s) and the data collection system.
3. An engine cooling system with sufficient capacity to maintain the engine at normal operating temperatures prescribed by the manufacturer must be used.
4. An engine cooling system with sufficient capacity to maintain the engine at normal operating temperatures prescribed by the manufacturer shall be used.
5. A brief description of the vehicle type with regard to the heating system if the heating system uses the heat of the engine cooling fluid: …
6. For forced cool-down, good engineering judgement shall be used to set up systems to send cooling air across the engine, to send cool oil through the engine lubrication system, to remove heat from the coolant through the engine cooling system, and to remove heat from an exhaust after-treatment system.
7. COOLING SYSTEM: LIQUID/AIR COOLING [2] For the engine representative of the type to be approved, a complete data-set shall be supplied. For modified engines, only data which differ from this data-set need to be supplied.
8. The cooling liquid circulation shall be operated by the engine water pump only.Cooling of the liquid may be produced either by the engine radiator or by an external circuit, provided that the pressure loss of this circuit and the pressure at the pump inlet remain substantially the same as those of the engine cooling system.
9. The cooling liquid circulation shall be operated by the engine water pump only.Cooling of the liquid may be produced either by the engine radiator or by an external circuit, provided that the pressure loss of this circuit and the pressure at the pump inlet remain substantially the same as those of the engine-cooling system.
10. Immediately after the engine is turned off, the engine cooling fan(s) shall be turned off if used, as well as the CVS blower (or disconnect the exhaust system from the CVS), if used.
11. Charge air cooled engines shall be tested with charge air cooling, whether liquid or air cooled, but if the engine manufacturer prefers, a test bench system may replace the air cooled cooler.
12. Charge air-cooled engines shall be tested with charge air cooling, whether liquid- or air-cooled, but if the engine manufacturer prefers, a test bench system may replace the air-cooled cooler.
13. ‘All engines that expel exhaust gases mixed with water shall be equipped with a connection in the engine exhaust system that is located downstream of the engine and before any point at which the exhaust contacts water (or any other cooling/scrubbing medium) for the temporary attachment of gaseous or particulate emissions sampling equipment.
14. The cooling liquid circulation shall be operated by the engine water pump only.Cooling of the liquid may be produced either by the engine radiator or by an external circuit, provided that the pressure loss of this circuit and the pressure at the pump inlet remain substantially the same as those of the engine-cooling system. The radiator shutter, if incorporated, shall be in the open position.Where the fan, radiator and cowl system cannot conveniently be fitted to the engine, the power absorbed by the fan when separately mounted in its correct position in relation to the radiator and cowl (if used), must be determined at the speeds corresponding to the engine speeds used for measurement of the engine power either by calculation from standard characteristics or by practical tests.
15. ‘All engines that expel exhaust gases mixed with water shall be equipped with a connection in the engine exhaust system that is located downstream of the engine and before any point at which the exhaust contacts water (or any other cooling/scrubbing medium) for the temporary attachment of gaseous or particulate emissions sampling equipment. It is important that the location of this connection allows a well mixed representative sample of the exhaust.
