Masquito M80
__NOTOC__ The Masquito M80 was a Belgian two-seat ultralight helicopter designed and built by Masquito Aircraft. Design and development The prototype was designated the Maschelin M58 Masquito. It was a conventional pod and boom design and was powered by a Rotax 582 engine driving a two-bladed main rotor and a two-bladed tail rotor. It had two side-by-side seats and was fitted with two fixed skids as a landing gear. The M58 first flew in May 1996; it was later modified to the proposed production standard with a Jabiru 2200 engine and re-designated the M80. Three further M80 prototypes were built but the type failed to gain the appropriate certification and no others were produced. A Belgian company, D-Motor was set up to design and build a suitable motor for the M80. Two engines with a high power-to-weight ratio were produced: first, the D-Motor LF26 (a flat four) and, later, the D-Motor LF39 (a flat-six). Unlike the Jabiru motor, these Belgian horizontally-opposed engines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flat Four
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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-1950s 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 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called '' engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel-injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...

Horizontally-opposed
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engines ...

Flat-six
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. 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 The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine bal ...) 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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 engine, the D-Motor LF39, which is claimed to produce and to have dry weight of .

Jabiru 2200
The Jabiru 2200 is a lightweight naturally aspirated, pushrod four-stroke, flat four, air-cooled aircraft engine produced by Jabiru Aircraft. Design and development The conventional direct-drive engine is fitted with an alternator, silencers, vacuum pump drives and dual ignition systems as standard. The engine generates up to 80 bhp at 3,300 rpm. In Europe the engine competes with the Rotax 912, another flat four four-stroke engine, but one that has water-cooled cylinder heads and a geared reduction drive to the propeller. Jabiru Aircraft began as a builder of small two-seater aircraft in Bundaberg, Australia. It turned to producing its own engines when supplies of the Italian-sourced engines previously used dried up. Jabiru engines are designed to be manufactured in small batch quantities, so the firm uses CNC machines to mill major engine parts such as cylinder blocks and heads, rather than using cast items. A larger variant of this engine is the flat-six Jabiru 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
