考题
第一组Older loop scavenged engines may have a single injector mounted centrally in the cylinder head. Because the exhaust valve is in the center of the cylinder head on modern uniflow scavenged engines the fuel valves (2 or 3) are arranged around the periphery of the head. The pressure at which the injector operates can be adjusted by adjusting the loading on the spring. The pressures at which the injectors operate vary depending on the engine, but can be as high as 540 bar. Some injectors have internal cooling passages in them extending into the nozzle through which cooling water is circulated. This is to prevent overheating and burning of the nozzle tip. Injectors on modern engines do not have internal cooling passages. They are cooled by a combination of the intensive bore cooling in the cylinder head being close to the valve pockets and by the fuel which is re-circulated through the injector when the follower is on the base of the cam or when the engine is stopped. As well as cooling the injector, re-circulating the fuel when the engine is stopped keeps the fuel at the correct viscosity for injection by preventing it from cooling down. Fuel injectors must be kept in good condition to maintain optimum efficiency, and to prevent conditions arising which could lead to damage within the cylinder. Injectors should be changed in line with manufacturers recommendations, overhauled and tested. Springs can weaken with repeated operation leading to the injector opening at a lower pressure than designed. The needle valve and seat can wear which together with worn nozzle holes will lead to incorrect atomization and dribbling.Modern uniflow scavenged engines have______.A.a single injector mounted in the center of the cylinder headB.several injectors mounted around the external boundary of the cylinder headC.a single injector mounted at the external boundary of the cylinder headD.several injectors mounted in the center of the cylinder head

材料：Condor a catamaran vessel operating between the Channel Islands and France．The vessel has two main engines in each hull．All propulsion units are duplicated，with each set independent from the other．Shortly after leaving St Helier，Jersey，with 31 passengers and 18 crew，the fire alarm sounded indicating a fire in the starboard engine room．This was confirmed by the closed circuit television surveillance system which showed flames in the vicinity of the starboard outer main engine．The vessel was immediately stopped，all machinery in the starboard engine room was stopped and the fuel supplies shut down．Jersey Radio was informed of the situation two minutes after the alarm sounded. After closing all ventilation openings and accounting for all personnel，halon fire smothering gas was released into the starboard engine room．This was done five minutes after the fire alarm first sounded. The crew maintained boundary cooling and intermittently operated the sprinkler system to the affected space．Twenty minutes after the alarm sounded the situation was considered to be under control．Using the port main engines the vessel returned to St Helier where assistance was available from shore based emergency services．问题：Condor has two ________ main engines．A.combinedB.independentC.coupleD.doubleThe fire accident happened in ________．A.both the engine roomsB.neither engine roomsC.the port engine roomD.the starboard engine roomThe fire was mainly extinguished with ________．A.waterB.chemical agentC.foamD.powderIt can be concluded that ________．A.no officials from any authority know the accident after it happenedB.some officials ashore must have learnt the accident at very beginningC.there must be casualties even they were not mentioned in the reportD.fire is not dangerous on board vessel请帮忙给出每个问题的正确答案和分析，谢谢！
