Minkow and 10 of his associates were named in the count indictment here Friday, six months after the carpet-cleaning company was forced into bankruptcy proceedings and then liquidated.
VW is undeniably very bright as carmakers go, yet as a marque it is noticeable for not having a single turbocharged petrol car in its range. For its performance cars it has, since venturing into the hot car class with the Golf GTI, always done the job the classic way with fitting a big enough, powerful enough, healthily breathing, normally aspirated engine.
For the performance variant, exhaust-driven turbocharging has taken over in so many other cases, not least at Audi with the brilliant quattro. There is so much to be said for the turbo, especially if the engine to be boosted is of 1.
But turbos have some disadvantages, some of which become more significant on road cars, particularly with small engines. In nearly every turbo, lag and the lack of bottom end power spoil response and enforce or encourage wasteful down-changing, or driving in one gear too low.
For the engineer, there are the considerable problems of extra under-bonnet heat, more expensive manifolding, a more space-consuming engine, turbo controls, and extra weight.
Turbo engines are not efficient at low speeds, because the full effective compression ratio is not realised. Remember that turbocharging is just another way of supercharging, or forcing induction.
Talking of mechanical supercharging is not strictly logical, as exhaust-driven turbines are no less mechanical than gear trains or belts.
The Roots type of direct-drive blower, originating before the war and used extensively today in drag racing, has two paddle-like rotors that revolve closely meshing inside a casing. There was a host of other types of compressors, but these two predominated.
They worked, but they had their drawbacks. Both could be noisy aerodynamically, because of the sharp changes of volume, and sometimes mechanically as well. The mechanical side of the vane type was usually its downfall, depending on the lubrication which, if too frugal, affected compressor sealing and, if too liberal, could mean oil in the inlet air, and other mechanical problems.
As a general rule, the engine power needed to drive superchargers could become self-defeating. The strength of the turbo is that although it takes engine power to drive it via the energy of the exhaust gasesit compensates to some extent in the low friction of its rotor bearing, and in the more ideal cases, with a degree of recovery of the exhaust gas heat energy.
VW worked with both Roots and vane blowers, confirming their good and bad points, which inspired a further look at something which could be as mechanically reliable as a Roots, and effective in pumping as a vane.
VW found it in an old idea — the spiral blower. A Frenchman, Leon Creux of Paris, patented the principle in He primarily saw his spiral engine as just that, an engine, driven by an external source of pressurised fluid such as steam.
Here the word engine was used in its original sense, for any moving mechanism.
It is significant that of the five new patents applied for by VW, one concerns the high-speed milling machine developed to finish the spirals.
VW is not the only one to examine the spiral blower. Hitachi of Japan has a spiral-type air conditioning compressor, and others have proposed something similar.
But it is Volkswagen who have first applied the idea to a car. And they have done so very thoroughly. Imagine a round cake tin.During the 9-day period preceding its filing of a petition under Chapter 7 of the Bankruptcy Code, ZZZZ Best Co., Inc.
(Debtor) made two interest payments and paid a loan commitment fee on its long-term debt to petitioner, Union Bank (Bank).
After he was appointed trustee of the Debtor's estate. ZZZZ Best’s auditors obtained third-party confirmations to support the contracts, reviewed available documentation, performed analytical procedures to evaluate the reasonableness of the revenues recorded on the contracts, and visited selected restoration sites.
ZZZZ Best Company Fraud Case Study 1) At an early age, First limitation of the evidence is its insufficiency to support the occurrence, reliability and relevance of events and transactions. Mere paperwork is not enough to prove an event to have existed. It also needs inquiries from people accountable in recording or recognizing such events.
Upon the performance of those procedures, the auditors of ZZZZ Best Inc. had obtained evidence in order to draw reasonable conclusions on which to base the audit opinion.
