solving the problem of (technical writing)

[kvvic]

This is an introductory sentence from a research paper about superalloys. Could you please check this sentence, first of all, from the stanpoint of style. Specifically, I'm in doubt about the words in bold. Are such phrases acceptable in technical writing or do they sound too cumbersome?
Of course, I'd appreciate any other comments and suggestions.

Development and improvement of technologies for producing novel materials and methods for their protection are a vital prerequisite in solving the problem of ensuring the reliability and high efficiency of stationary and vehicular power plants, as well as in creating new-generation engines.

Development and improvement of technologies for producing novel materials and methods for their protection are a vital prerequisite in solving the problem of ensuring the reliability and high efficiency of stationary and vehicular power plants, as well as in creating new-generation engines.

It's grammatically OK, but it will exhaust the reader.

This one will, too:
Development and improvement of technologies for producing novel materials and methods for their protection are vital prerequisites when solving problems of ensuring reliability and high efficiency of stationary or vehicular power plants, as well as creating new-generation engines.

Then I'll throw out "solving problems of". This won't change the meaning and the sentence will be a little bit easier to read, I hope.

Development and improvement of technologies for producing novel materials and methods for their protection are vital prerequisites when ensuring reliability and high efficiency of stationary or vehicular power plants, as well as creating new-generation engines.

...ensuring [zero article] reliability and high efficiency...
Could you please explain it to me? There're no articles in my mother tongue and so I don't always use them properly. I thought ...the reliability and high efficiency... would mean the degree of reliability and the level of efficiency that are required of the power plants.

The articles are not necessary. They can be placed there, if you wish.

I felt it "tightened up" this lengthly sentence without them.

Thanks again for the explanation. It's not that I wish to place the article. I'm just trying to understand when the articles are necessary and when they're not.
