A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids.
Four-wheel drive, also called 4x4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.
A diesel–electric transmission, or diesel–electric powertrain is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a very similar transmission system used for petrol engines.
A zero-emission vehicle, or ZEV, is a vehicle that does not emit exhaust gas or other pollutants from the onboard source of power. The California definition also adds that this includes under any and all possible operational modes and conditions. This is because under cold-start conditions for example, internal combustion engines tend to produce the maximum amount of pollutants. In a number of countries and states, transport is cited as the main source of Greenhouse gases and other pollutants. The desire to reduce this is thus politically strong.
Global Hybrid Cooperation is a set of hybrid vehicle technologies jointly developed by General Motors, Daimler, and Chrysler LLC, with BMW joining in 2005. It uses 2 or 3 planetary gearsets in an automatic transmission: one on the internal combustion engine side paired with a second, forming the compound split, and possibly one third additional planetary gearset to multiply the number of fixed gear ratios. General Motors has stopped using the "AHS2" name as of 2006, preferring to call it simply a "two-mode hybrid system".
A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines or batteries, alternated with conventional fossil fuel.
An electro-diesel locomotive is a type of locomotive that can be powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
In computing, a hybrid drive is a logical or physical storage device that combines a faster storage medium such as solid-state drive (SSD) with a higher-capacity hard disk drive (HDD). The intent is adding some of the speed of SSDs to the cost-effective storage capacity of traditional HDDs. The purpose of the SSD in a hybrid drive is to act as a cache for the data stored on the HDD, improving the overall performance by keeping copies of the most frequently used data on the faster SSD.
A dual-mode vehicle (DMV) is a vehicle that can run on conventional road surfaces, a railway track or a dedicated track known as a "guideway". Dual-mode vehicles are commonly electrically powered and run in dual-mode for power too, using batteries for short distance and low speeds, and track-fed power for longer distances and higher speeds. Dual-mode vehicles were originally studied as a way to make electric cars suitable for inter-city travel without the need for a separate engine. More recently, starting in the 1990s, a number of dual-mode transit mass transit systems have appeared, most notably a number of rubber tyred trams and guided buses. The subset of dual-mode vehicles using conventional railtracks and roads are called road–rail vehicles. Dual mode transit describes transportation systems in which dual-mode vehicles operate on both public roads and on a guideway; thus using two modes of transport. In a typical dual mode transit system, private vehicles comparable to automobiles would be able to travel under driver control on the street, but then enter a guideway, which may be a specialized form of Railway or monorail, for automated travel for an extended distance.
Hybrid vehicle drive trains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power.
A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks, buses, boats and aircraft also exist.
The General Motors Precept was a 2000 low emission vehicle concept car aimed at meeting the 80 mpg‑US fuel economy goal of the Partnership for a New Generation of Vehicles between the US Government and GM, Ford, and Chrysler. GM was able to meet the 80 mpg‑US fuel economy goal with the Precept, creating versions using Lithium and NiMH batteries with diesel, fuel cell and other hybrid version of the car.
A hybrid vehicle is a vehicle which uses a mixture of power or fuel sources.
AMD Hybrid Graphics technology, is a collective brand from AMD for its Radeon line of discrete and integrated GPU, promoting higher performance and productivity while saving energy consumption in GPUs.
The Bombardier ALP-45DP is a type of single cab dual-mode locomotive built by Bombardier Transportation and operated by New Jersey Transit and Exo.
The Stadler Euro Dual is a series of dual power, electro-diesel locomotive by Stadler Rail Valencia. Unlike traditional dual mode locomotives, fitted with relatively low-powered diesel engines for 'last mile' movements only, vehicles are typically furnished with power units more comparable to that of mainline diesel locomotives.
In automotive engineering, the drivetrain is the group of components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power.
An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit that can be powered either by electric power picked up from the overhead lines or third rail or by using an onboard diesel engine, driving an electric generator, which produces AC or DC electric power.
The WEY Latte is a compact crossover SUV produced by Great Wall Motor under the premium brand, WEY.
