Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. An alternative configuration for flat engines is a 180-degree V engine, where both cylinders move to the right then the left at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 '' Wilson-Pilcher 18/24 HP'' c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fl ...

Porsche 911 2
Dr. Ing. h.c. F. Porsche AG, usually shortened to Porsche (; see below), is a German automobile manufacturer specializing in luxury, high-performance sports cars, SUVs and sedans, headquartered in Stuttgart, Baden-Württemberg, Germany. The company is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE, usually shortened to Porsche SE. Porsche's current lineup includes the 718, 911, Panamera, Macan, Cayenne and Taycan. The origins of the company date to the 1930s when German Bohemian automotive engineer Ferdinand Porsche founded Porsche with Adolf Rosenberger, a keystone figure in the creation of German automotive manufacturer and Audi precursor Auto Union, and Austrian businessman Anton Piëch, who was, at the time, also Ferdinand Porsche's son in law. In its early days, it was contracted by the German government to create a vehicle for the masses, which later became the Volkswagen Beetle. After World War II, when Ferdinand, a me ...

Overhead Valve Engine
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. However, some designs have the camshaft in the cylinder head but still sit below or alongside the valves (the Ford CVH and Opel CIH are good examples), so they can essentially be considered overhead valve designs. Some early intake-over-exhaust engines used a hybrid design combining eleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Revolution Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min−1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to hertz. Standards ISO 80000-3:2019 defines a physical quantity called ''rotation'' (or ''number of revolutions''), dimensionless, whose instantaneous rate of change is called ''rotational frequency'' (or ''rate of rotation''), with units of reciprocal seconds (s−1). A related but distinct quantity for describing rotation is ''angular frequency'' (or ''angular speed'', the magnitude of angular velocity), for which the SI unit is the radian per second (rad/s). Although they have the same dimensions (reciprocal time) and base unit (s−1), the hertz (Hz) and radians per second (rad/s) are special names used to express two different but proportional ISQ quantities: frequency and angular frequency, respectively. The conversions between a frequency and an angular frequency are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

D-Motor LF26
The D-Motor LF26 is a lightweight liquid cooled side-valve four-stroke flat four, 2.7 litre petrol aircraft engine, produced by D-Motor in Deerlijk, Belgium. Design and development This direct-drive aero-engine is unusual in two respects: it is very oversquare with a bore:stroke ratio of 1.295:1, and it has a side-valve (flathead) valvetrain. The designer determined that since maximum continuous power output (65.3 kW) was to be developed at only 2800 rpm, the extra weight and complexity of overhead valves (OHV) would be superfluous. The resulting engine is compact and lightweight, with a dry weight of , and a maximum power-to-weight ratio of 1.09 kW/kg (wet; coolant fluids weigh ). The engine has port injection, a dry sump lubrication system, and dual ignition. Variants With the aid of funding from the Belgian government, D-Motor has developed a derivative 4-litre flat-six A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston en ...

D-Motor LF39
The D-Motor LF39 is a lightweight liquid cooled side-valve four-stroke flat six 4 litre petrol aircraft engine, produced by D-Motor in Deerlijk, Belgium. It is a derivative of the flat four D-Motor LF26. Design The LF39 produces and has a dry weight of . The power curve is virtually linear from 50 kW @ 1920 rpm to 91.55 kW @ 3100 rpm. Just like its smaller sibling, the LF26, this direct-drive aero-engine has a side-valve (flathead) valvetrain. The engine has port injection, a dry sump lubrication system, and dual ignition. Development With the aid of funding from the Belgian government, the D-Motor LF39 was developed from the LF26. The company encountered problems with the casting of the flat-six cylinder block and there were further problems with the flywheel/alternator, but these were solved using a lighter flywheel with neodymium magnets. The 2014 expected price was €17,800. In September 2014, EDM Aerotec announced the results of test flying the en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1960s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
