Automobile
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Straight-eight
The straight-eight engine (also referred to as an inline-eight engine; abbreviated I8 or L8) is a piston engine with eight cylinders arranged in a straight line along the crankshaft. The number of cylinders and perfect primary and secondary engine balance resulted in smooth running, however there are several downsides relating to the significant length of the engine. Straight-eight engines were popular in luxury cars and racing cars in the 1920s to 1940s. During the 1950s, straight-eight engines were largely replaced by the more compact V8 engine design. Design A straight-eight can achieve perfect primary balance and secondary balance if an appropriate firing order is used. Like most other engines, torsional vibration of the crankshaft requires that a harmonic damper is installed on the crankshaft. at the accessory end of the crankshaft. As per other engines with 8 cylinders, the power delivery is smoother than engines with fewer cylinders. In the early 20th century, thes ...

Hardtop
A hardtop is a rigid form of automobile roof, which for modern cars is typically constructed from metal. A hardtop roof can be either fixed (i.e. not removable), detachable for separate storing or retractable within the vehicle itself. The '' pillarless hardtop'' (often referred to as simply "hardtop") is a body style of cars without a B-pillar, which are often styled to give the appearance of a convertible design. Pillarless hardtops The pillarless hardtop (abbreviated as "hardtop") is a post-World War II car body designed with no center or B-pillar styled to resemble a convertible. If window frames are present, they are designed to retract with the glass when lowered. This creates an impression of uninterrupted glass along the side of the car. Although having a rigid metal roof, the stylists sometimes make the "hardtop" cars appear to be like a convertible with its top up. Even the smaller automakers like Packard introduced two door hardtops in 1952 "as a resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedan (car)
A sedan or saloon (British English) is a passenger car in a three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of the word "sedan" in reference to an automobile body occurred in 1912. The name derives from the 17th-century litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet/sedanette. Definition A sedan () is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice, the typical characteristics of sedans are: * a B-pillar (between the front and rear windows) that supports the roof * two rows of seats * a three-box design with the engine at the front and the c ...

Touring Car
Touring car and tourer are both terms for open cars (i.e. cars without a fixed roof). "Touring car" is a style of open car built in the United States which seats four or more people. The style was popular from the early 1900s to the 1930s. The cars used for touring car racing in various series since the 1960s, are unrelated to these early touring cars, despite sharing the same name. "Tourer" is used in British English for any open car. The term "all-weather tourer" was used to describe convertibles (vehicles that could be fully enclosed). A popular version of the tourer was the torpedo, with the hood/bonnet line at the car's waistline giving the car a straight line from front to back. Touring car (U.S.) Design ''Touring car'' was applied in the U.S. to open cars (cars without a fixed roof, for example convertibles) that seat four or more people and have direct entrance to the tonneau (rear passenger area), although it has also been described as seating five or more people ...

Hydraulic Brake
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism. History During 1904, Frederick George Heath (Heath Hydraulic Brake Co., Ltd.), Redditch, England devised and fitted a hydraulic (water/glycerine) brake system to a cycle using a handlebar lever and piston. He obtained patent GB190403651A for “Improvements in hydraulic actuated brakes for cycles and motors”, as well as subsequently for improved flexible rubber hydraulic pipes. In 1908, Ernest Walter Weight of Bristol, England devised and fitted a four-wheel hydraulic (oil) braking system to a motor car. He patented it in Great Britain (GB190800241A) in December 1908, later in Europe and the USA and then exhibited it at the 1909 London Motor Show. His brother, William Herbert Weight improved the patent (GB190921122A) and both were assigned to the Weight Patent Aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colonial (1921 Automobile)
The Colonial was an American automobile manufactured in Boston by the Colonial Motors Corporation from 1921 until 1922. Although the company pledged to produce "in excess of 100 cars" during its first year in business no more than a dozen are believed to have left the factory. Each car had a 130-inch wheelbase and a six-cylinder Beaver engine. A complete line of open and closed body styles was advertised, but the few completed models all appear to have been open. Disc wheels were a feature of all models, and prices were approximately $5,000 for all body styles.

Colonial (Shaw Automobile)
The Shaw renamed the Colonial for 1921, was an American luxury automobile that was manufactured in Chicago, Illinois from 1920 until 1921. At the end of 1921 the Colonial was rebranded the Ambassador. History Walden W. Shaw and John D. Hertz, owners of the Walden W. Shaw Livery Corporation, decided they wanted to expand into the production car market with a luxury car. Walden W. Shaw Livery Corporation owned the Yellow Cab Manufacturing Company. The new luxury automobile was introduced as a Shaw at the Hotel Congress during Chicago Automobile Show week in February 1920. With Shaw taxicabs being so well known, using the Shaw name for a luxury car would not help sales so the name was changed to Colonial. This may have been no improvement, as several car makes had already been called Colonial. The Colonial was built on a 136-inch wheelbase and was offered as a 2, 4 or 7 passenger touring car priced at $5,000, . Shaw and Hertz also change their mind about the engine. Initially ...
