plug – свеча зажигания

gauge – измерительный прибор

to charge – заряжать батареи

to adjust – регулировать

– Donald, I know you are a driver of long standing. I would like you to have a look at my car.

– What’s wrong with your car?

– I don’t know yet. I can’t trace the fault.

– Let me have a look. When did you have your plugs checked?

– Three days ago. I thought I had run out of gas but the tank is half full.

– Have a look at the patrol gauge once more.

– All right. The tank is half full, as I have already said.

– The carburetor is in order. The engine is misfiring.

– So it is.

– I guess the battery has run down. It needs recharging.

– Too bad.

– Don’t get upset about it. It won’t take you long to have your battery recharged.

– Do you really think so?

– I am sure of it. The other day I went to the gas station to have the brakes adjusted. They did it in no time.

– Where is the gas station?

– It’s three miles south of the supermarket. Do you know the place?    

– I think so. In my car the brakes are a bit slack. I hope they can easily be adjusted.

– I advise you to have the engine greased.

– I’ll follow your advice. Thank you, Donald.

– Don’t mention it, Paul. I’m very sorry I couldn’t help you.

– Well, you have helped me to trace the fault. I wish I had bought a new car…

– Well, this one is much cheaper. It hasn’t got too many miles on it. It’s practically new.

– I must admit it runs smoothly. It was in good condition when I bought it.

– When was it?

– A year ago.

LITTLE SQUIRT

Delphi has unveiled the next-generation of its Multec common rail technology, which now uses a unique solenoid injector design to optimize fuel rate, spray shape and accuracy. The new system provides the smallest injection quantities, highest precision fuel delivery and, along with closed loop strategies, results best-in class emission and acoustics performance, claims Delphi.

It can deliver up to 5 injections per cycle, allowing high flexibility for combustion optimization. In addition, it is capable of 1,800 bar system pressure, although initial Euro 5 applications are at 1,600 bars.

Delphi has also introduced a unique, piezo-based injector that compared to current piezo common rail technologies is expected to generate a 25 – 30 per cent reduction in emission in its first implementation and possibly leading to better results with further combustion optimization.

This Piezotec injection system will help OEMs meet Euro 5 emissions regulations on heavier vehicles and stringent new US emissions regulations, claims Delphi. It can deliver up to 7 or more injection events per cycle with extremely high fuel quantity accuracy for pilot, main and post events. The design breakthrough allows dramatically reduced spacing between events, giving engine designers full freedom to shape the flow of fuel throughout the combustion stroke.

Delphi has several diesel technologies including catalysed particulate traps, oxidation catalysed and NOx traps. It is currently developing a combined diesel NOx and particulate trap.
