Lightweighting is a concept in the auto industry about building cars and trucks that are less heavy as a way to achieve better fuel efficiency, battery range, acceleration, braking and handling. [1] [2] In addition, lighter vehicles can tow and haul larger loads because the engine is not carrying unnecessary weight. [3]
The average car weight in 2022 was 4,094 pounds, according to a report from the Environmental Protection Agency. However, what is considered a normal weight will depend on the type of vehicle you ...
A small engine is the general term for a wide range of small-displacement, low-powered internal combustion engines used to power lawn mowers, generators, concrete mixers and many other machines that require independent power sources. [1]
In the automotive industry, engine downsizing is the practice of utilizing smaller combustion engines over larger ones of the same power capacity when manufacturing vehicles. It is the result of car manufacturers attempting to provide more efficient vehicles that emit fewer emissions , [ 1 ] often mandated by legislative standards . [ 2 ]
The Midwest twin-rotor wankel engine has an eccentric shaft that spins up to 7,800 rpm, so a 2.96:1 reduction gear is used. Aero-engine reduction gears are typically of the gear type, but smaller two-stroke engines such as the Rotax 582 use belt drive with toothed belts, which is a cheap and lightweight option with built-in damping of power surges.
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...
It is street-legal in the US. Cars were exported to other countries, [10] sometimes being classified as a moped (e.g. the P50 that went to Finland). [11] In the Netherlands there are two original Peel Tridents registered as tricycles, but the Trident replica with the 50cc engine and 59 km/h (37 mph) top speed was registered as a moped. In ...
Extremely efficient vehicle designs capable of achieving 100+ mpg ‑US (2.4 L/100 km) (such as the VW 1L) do not have substantially greater engine efficiency, but instead focus on better aerodynamics, reduced vehicle weight, and using energy that would otherwise be dissipated as heat during braking.
