Volvo XC40
The Volvo XC40 is a subcompact luxury crossover SUV (C-segment) manufactured by Volvo Cars. It was unveiled on 21 September 2017 as the smallest SUV model from Volvo, below the XC60. Orders started in September 2017, and manufacturing began in November 2017. Along with conventional petrol and diesel engines, a plug-in hybrid model was introduced in 2019, and a fully electric model was released in 2020. Both the plug-in hybrid and the electric versions were marketed as the XC40 Recharge. In 2024, Volvo renamed the battery electric XC40 to the Volvo EX40, aligning it with newer battery electric models such as the EX30 and the EX90. A coupe version of the battery electric model with a sloping rear roof was released in 2021 as the C40 Recharge. It was renamed to the Volvo EC40 since 2024. The XC40 received the European Car of the Year Award at the 2018 Geneva Motor Show. and the car was named Car of the Year Japan for 2018/2019. Overview The design of the XC40 was previewed b ...

Volvo Engine Architecture
The Volvo Engine Architecture (VEA) is a family of straight-three and straight-four automobile petrol and diesel engines produced by Volvo Cars in Skövde, Sweden, since 2013, Zhangjiakou, China, since 2016 and Tanjung Malim, Malaysia, since 2022 by Proton. Volvo markets all engines under the ''Drive–E'' designation, while Geely groups the three-cylinder variants with its other engines under the ''G-power'' name. These engines are some of the few ever put into production as twincharged engines, in the company of the Lancia Delta S4 and concept Jaguar CX-75. History Development of the new engine family began in 2006, with the decision to only produce four-cylinder engines being finalised in 2007. The intention was to produce smaller, more economical and environmentally friendly engines that would be fitted to every Volvo model. In 2008 Volvo began to upgrade its Skövde engine plant and invested roughly 2 billion SEK into development and tooling for the VEA. In the autumn of ...

Coupé SUV
A coupe SUV is a type of sport utility vehicle with a sloping rear roofline similar to those of fastbacks or Kammbacks. The sloping roofline is adopted to offer a styling advantage compared to its standard SUV counterpart, which helps increase profit margins as manufacturers are able to raise the price by marketing it as a more premium model. Since all coupe SUVs ever produced are of the crossover variety, coupe SUVs may also be called "coupe crossovers" or "coupe crossover SUVs". Although the term "coupe" itself is supposed to refer to a passenger car with a sloping or truncated rear roofline and two ( or three) doors, traditional two-door SUVs (including body-on-frame SUVs) such as certain models of Toyota RAV4 and Jeep Wrangler are never considered by such terms, and every coupe SUV by definition (except for the Range Rover Evoque Coupé) is equipped with five doors. The body style notably gained criticism as some see it as less attractive and less practical than normal cross ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front-engine, All-wheel-drive
In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving. In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain. The Weak architecture produces a vehicle with a large powersplit between the front and rear powertrains, while the Strong architecture recommends a vehicle with more similar power and torque requirements for the front and rear. Most four-wheel-drive layouts are front-engined and are derivatives of earlier front-engine, rear-wheel drive, or front-engine, front-wheel drive designs. The first origins of it were intr ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...

Permanent Magnet Synchronous Motor
A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integer number of AC cycles. Synchronous motors use electromagnets as the stator of the motor which create a magnetic field that rotates in time with the oscillations of the current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field. Doubly fed synchronous motors use independently-excited multiphase AC electromagnets for both rotor and stator. Synchronous and induction motors are the most widely used AC motors. Synchronous motors rotate at a rate locked to the line frequency since they do not rely on induction to produce the rotor's magnetic field. Induction motors require '' slip'': the rotor must rotate at a frequency slightly slower than the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that couples a conventional internal combustion engine (ICE) with one or more electric engines into a hybrid vehicle drivetrain, combined propulsion system. The presence of the electric powertrain, which has inherently better energy conversion efficiency, is intended to achieve either better fuel economy in automobiles, fuel economy or better acceleration performance than a conventional vehicle. There is a variety of HEV types and the degree to which each functions as an electric vehicle (EV) also varies. The most common form of HEV is hybrid electric passenger cars, although hybrid electric trucks (pickup truck, pickups, tow trucks and tractors), buses, motorboats, and aircraft also exist. Modern HEVs use energy recovery technologies such as motor–generator units. and regenerative braking to recycle the vehicle's kinetic energy to electric energy via an alternator (automotive), alternator, which is energy storage, st ...

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a Slant-4 engine, slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the inv ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engine, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976–1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...
