Frivolous Litigation

Frivolous litigation, as used in colloquial and political terms in the United States, refers to lawsuits that are based on a theory that seems absurd, or where the claim results in damages that greatly exceed what one would expect from reading a brief summary of the case. Awards for medical malpractice are sometimes derided as frivolous (in this sense of meaning "excessive"). If a jury and a judge decided in favor of the plaintiff in such cases, the plaintiff's claim was not technically frivolous in legal terms, though it might be considered frivolous colloquially. Because of the ambiguity in the term, calling these lawsuits "frivolous" can lead to confusion because opposite sides of the tort reform debate can both say they oppose "frivolous" suits, with the tort reform supporters referring to the colloquial understanding, and tort reform opponents referring to the narrower technical definition. The typical definition in United States law is very different from its colloquial or political meaning. United States courts usually define "frivolous litigation" as a legal claim or defense presented even though the party and the party's legal counsel had reason to know that the claim or defense had no merit. A claim or defense may be frivolous because it had no underlying justification in fact, or because it was not presented with an argument for a reasonable extension or reinterpretation of the law, or because laws are in place unequivocally prohibiting such a claim (see Good Samaritan law). In the United States, Rule 11 of the Federal Rules of Civil Procedure and similar state rules require that an attorney perform a due diligence investigation concerning the factual basis for any claim or defense. Jurisdictions differ on whether a claim or defense can be frivolous if the attorney acted in good faith. Because a frivolous defense or claim wastes the court's and the other parties' time, resources and legal fees, sanctions may be imposed by a court upon the party or the lawyer who presents the frivolous defense or claim. The law firm may also be sanctioned, or even held in contempt.

Gasoline Engines

Gasoline engines have the advantage over diesel in being lighter and able to work at higher rotational speeds and they are the usual choice for fitting in high-performance sports cars. Continuous development of gasoline engines for over a hundred years has produced improvements in efficiency and reduced pollution. The carburetor was used on nearly all road car engines until the 1980s but it was long realized better control of the fuel/air mixture could be achieved with fuel injection. Indirect fuel injection was first used in aircraft engines from 1909, in racing car engines from the 1930s, and road cars from the late 1950s.

Gasoline Direct Injection (GDI) is now starting to appear in production vehicles such as the 2007 BMW MINI. Exhaust gases are also cleaned up by fitting a catalytic converter into the exhaust system. Clean air legislation in many of the car industries most important markets has made both catalysts and fuel injection virtually universal fittings. Most modern gasoline engines are also capable of running with up to 15% ethanol mixed into the gasoline - older vehicles may have seals and hoses that can be harmed by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentrations as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be started on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engines cars can also run on LPG with the addition of an LPG tank for fuel storage and carburetion modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork lift trucks that have to operate inside buildings.
