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.

Auto Insurance

Defined as: The contract by which the insurer assumes the risk of any loss the owner or operator of a car may incur through damage to property or persons as the result of an accident. There are many specific forms of automobile insurance, varying not only in the kinds of risk that they cover but also in the legal principles underlying them.

In “plain” English, this means coverage that is carried by someone who is driving a motor vehicle that is involved in an accident that causes property damage or personal injury to someone.

Currently, New Hampshire and Wisconsin do not have “compulsory auto insurance liability laws”. Simply put, this means that these states do not require licensed drivers (and there should not be any other kind of driver) to have some type of auto insurance policy that provides at least minimum coverage. The remaining 48 states do have such insurance laws in effect.

You should check with the state you live in if you have questions concerning whether or not you are required to have auto insurance, and also to determine if you are required to have a certain amount of coverage. If you are required to have a certain amount, you will then need to check to see if there is a minimum amount and maximum amount.
