In 1968, gm's Ozzie toronado improved and developed the wedge-shaped car, and in 1968, it was adopted by the Cadillac premium sedan, eldo. Wedges are widely used in racing cars. Because the car first considers the influence of fluid mechanics (aerodynamics) and other issues on the automobile, the body can be made entirely by wedge, while the ride comfort is considered as a secondary consideration. Like the Italian ferrari in the 1980s, it was a typical wedge shape. Wedge shape for currently considering the high-speed car, whether from the aspects of its modelling concise, move feeling, or from its embodiment of aerodynamics, are conform to the requirements of the modern people's subjective, with a strong contemporary breath, give a person with beautiful enjoyment and speed fast. Japan's Toyota motor co., the MR2, is an engine sports car (the tail is fitted with a flexible flow board) that can be called a car in a wedge car. The car engine is in the design phase, and the fuel used for the compression ratio is set. The compression ratio is a very important structural parameter of the engine, which indicates the volume of the gas at the beginning of the piston at the beginning of compression and the volume ratio of the gas volume at the end of the piston. In terms of power and economy, compression ratio should be bigger and better. The compression ratio is high, the power is good, the heat efficiency is high, the vehicle acceleration, the top speed of the car will be improved accordingly. However, the compression ratio of the gasoline engine is not too large due to the performance of the cylinder material and the vibration of gasoline combustion. In short, a high compression ratio USES a high grade fuel oil. The higher the fuel mark, the slower the oil will burn, and the lower the combustion detonation, the higher the compression ratio of the engine. On the contrary, the low-grade fuel combustion rate is faster, the combustion explosion is large, the engine compression is lower. The powerful duo from the supermodel Gisele Bundchen and NFL superstar Tom Brady are put on the first position with this ranking. After a monster year stuffed with fashion and endorsement deals, Gisele Bundchen is just about the world's first billionaire supermodel with a massive $45 million over the 12-month period. Moreover, Tom Brady wasn't also overshadowed by his more famous wife. He bought home another $31 million using a four-year symbol of $72 million contract extension in September and NFL's richest deal, putting the couple's combined annual earnings at $76 million. Generally speaking, the interest rate varies according to the term of measurement, indicating that the method has annual interest rate, monthly interest rate and daily interest rate. It includes garbage trucks, refrigerated truck trucks, dump trucks carrying sand, concrete transporters, tankers, as well as trailers, semi-trailers, container trucks, etc.
