Wankel engine

A rotary internal combustion engine invented by Felix Wankel (1902-1988). It consists of an equilateral triangular member with curved sides orbiting about an eccentric on a shaft inside a stationary housing whose inner working surface is in the shape of an epitrochoid. The rotor is in sliding contact with the eccentric and imparts power to the eccentric shaft as a connecting rod does to a crankshaft. With one-third of a rotor revolution per shaft revolution and a power impulse for each of the three rotor sides, the Wankel generates one power impulse per revolution per rotor—twice that of what the four-cycle piston engine produces. Thus it has become accepted practice to multiply the geometry displacement of the Wankel by a factor of two for comparison with otto-cycle piston engines. The Wankel's advantages include compact size, light weight and smooth operation because there are no reciprocating parts. Its drawbacks include relatively high exhaust emission, possible sealing problems and low fuel economy. Mazda, however, has made significant improvements in all three areas.

Car Insurance Comparison – Why It is Important

Knowing what to look for when making a car insurance comparison is getting to be more important all of the time. Most, if not all states require motorists to have some level of auto insurance.

But now, states like Mississippi that do not have insurance databases are going to have them, and there must be proof of insurance before the automobile can get its tags renewed. According to the Jackson Free Press, the Mississippi legislature passed a new law in mid-March of 2011 requiring that motorists have more than just an insurance card, but actually have the insurance and be in the database. No insurance means no tags. This will prevent motorists from signing up for insurance and then canceling the policy to save money and still have the card.

With this becoming more common, it is more important now than ever to know how to make a car insurance comparison. Everyone wants to save money on auto insurance, and if that is the name of your game, you will want to get the absolute minimum that your state requires. That does not necessarily mean that you are going to have great insurance, though, because it will most likely just be liability. If your car still has some value to it, this may not be the best for you. If your car is totaled, you will have no way to recover the loss.

If you are already covered under a health insurance plan, it may not be necessary to get additional medical coverage with your auto insurance. If not, this could be crucial. Other additions that you will have to consider include towing, comprehensive coverage, theft, extra liability, car rental and a number of other options your agent will be happy to show you.
