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 ...

Plug-in Hybrid
A plug-in hybrid electric vehicle (PHEV) or simply plug-in hybrid is a type of hybrid electric vehicle equipped with a rechargeable battery pack that can be directly replenished via a charging cable plugged into an external electric power source, in addition to charging internally by its on-board internal combustion engine-powered generator. While PHEVs are predominantly passenger cars, there are also plug-in hybrid variants of sports cars, commercial vehicles, vans, utility trucks, buses, trains, motorcycles, mopeds, military vehicles and boats. Similar to battery electric vehicles (BEVs), plug-in hybrids can use centralized generators of renewable energy (e.g. solar, wind or hydroelectric) to be largely emission-free, or a fossil plant in which case they displace greenhouse gas emissions from the car tailpipe exhaust to the power station. As opposed to conventional hybrid electric vehicles (HEVs), PHEVs generally have a larger battery pack that can be recharged (the ...

Mild Hybrid
Mild hybrids (MHEV) (also known as smart hybrids, power-assist hybrids, battery-assisted hybrid vehicles or BAHVs) are generally cars with an internal combustion engine (ICE) equipped with a minimally extended battery and an auxiliary electric combined motor and generator in a parallel hybrid configuration that is only enough for an electric-only mode of propulsion at slow speed and allows the engine to be stopped whenever the car is coasting, braking, or stopped, and then restarted once power is required again. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine. Overview The mild hybrid's electric motor provides greater efficiency through the use of a single device that is essentially an integrated starter/alternator sometimes known as a generator-motor unit. A typical mild-hybrid setup uses a belt-powered generator-motor unit driven off the engine to supply power to a small battery. The generator is also powered throug ...

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 ...

BMW B48
The BMW B48 is a turbocharged inline-four petrol engine which replaced the BMW N20 and has been in production since 2014. It was first used in the F56 Mini Hatch and has been used in BMW applications since 2015. The B48 is part of a modular BMW engine family of 3-cylinder ( B38/ B37), 4-cylinder (B48/ B47) and 6-cylinder ( B58/ B57) engines, which use a displacement of per cylinder. A SULEV version of the BMW B48, the B46, is sold in the United States and other regions with strict emissions standards. Outside of minor differences, primarily with emissions control hardware, the two lines of engines are essentially identical and feature similar performance and reliability. Design Compared with its N20 predecessor, the B48 uses a more undersquare design, and an engine block using "closed-deck construction". As with the N20, the block and head are made from aluminium Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, ...

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-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 ...

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.

BMW B38
The BMW B38 is a turbocharged straight-three DOHC petrol engine, which replaced the straight-four BMW N13. Production started in 2013. It is part of a modular BMW engine family, of straight-three (B38), straight-four ( B48) and straight-six ( B58) alloy block and head petrol engines, which use a displacement of per cylinder in the 1.2 and per cylinder in the 1.5. It specifically shares a lot of components with the BMW B37, due to their same size/configuration. The B38 is used in front-wheel drive cars (such as the Mini Hatch and BMW 2 Series Active Tourer), as well as BMW's traditional rear-wheel drive and all-wheel drive (xDrive) configurations. The first car to use the B38 is the BMW i8 hybrid sports coupé, where it is used as a transverse mid-mounted engine. Design The B38 features direct injection, an 11:1 compression ratio, variable valve timing (double-VANOS) and the single-scroll turbocharger with the world's first aluminium turbine housing, manufactured b ...
