Horizontally-opposed
A flat engine is a Internal combustion engine#Reciprocating engines, 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, 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 ...

ULPower Aircraft Engines
ULPower Aero Engines is a Belgian company which manufactures engines specifically designed for light aircraft/rotorcraft use. History In 2001 the founding partners of ULPower were asked to fix an issue with a Jabiru engine fitted into a helicopter. By examining the setup they decided to build a new engine from scratch instead, because the particular Jabiru engine simply was too small for the application. The new engine should have the following aims and objectives: FADEC, simple, robust, easy to maintain, low parts count, high power to weight ratio and low cost of ownership. The founding partners had years of experience in the professional automotive rally industry. This included engine design, development and production for the Dakar Rally and a proprietary ECU Based on the years of engine experience from Rally, the prototype helicopter engine and the proprietary ECU, they decided to form a company producing aero engines. A couple of more objectives were added: The engine sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jabiru 5100
The Jabiru 5100 is a lightweight four-stroke horizontally opposed flat-eight air-cooled aircraft engine, manufactured by Jabiru Aircraft. Design and development The engine is direct-drive and is fitted with alternators, silencers, vacuum pump drives and dual-ignition systems as standard equipment. It was developed from the Jabiru 2200 and 3300 aeroengines, but whilst these earlier modular-design engines share the same bore and stroke (97.5mm x 74 mm), the 5100 flat-eight shares only the 97.5mm bore, and the stroke is increased from 74mm to 85mm. In November 2014 the Australian Civil Aviation Safety Authority proposed restricting all Jabiru-powered aircraft to day-visual flight rules only, without passengers or solo students and within gliding distance of a safe place to land due to the engine line's safety record. Both the manufacturer and Recreational Aviation Australia opposed the restrictions as unnecessary and unwarranted. The final rule adopted somewhat softened th ...

CAMit 3300
The CAMit 3300 is an Australian lightweight four-stroke, 6-cylinder, horizontally-opposed air-cooled aircraft engine. Direct drive and using a solid-lifter valvetrain, the 3300 develops at 3300rpm. The engine was manufactured by CAMit Pty Ltd, of Bundaberg, Queensland, Australia. CAMit has manufactured engines for Jabiru since the Italian-sourced engines used by Jabiru became unavailable in 1991. After receiving requests for and producing aftermarket Jabiru engine parts, CAMit went on to produce whole engines incorporating these modifications in late 2013. Many parts are interchangeable with the original components from Jabiru 3300 engine. However, in terms of component design, lubrication, valve train operation and metallurgy, the CAE engine is a completely different motor to the Jabiru design. The CAMit series of engines are classed as Experimental. Each serial number includes 'SLRE', designating 'Solid-Lifter Revised Experimental'. CAMit Pty Ltd ceased operation ...

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Electronic Ignition
An ignition system generates a spark or heats an electrode to a high temperature to ignite a fuel-air mixture in spark ignition internal combustion engines, oil-fired and gas-fired boilers, Rocket engine#Ignition, rocket engines, etc. The widest application for spark ignition internal combustion engines is in petrol (gasoline) road vehicles such as cars and motorcycles. Compression ignition Diesel engines ignite the fuel-air mixture by the heat of compression and do not need a spark. They usually have glowplugs that preheat the combustion chamber to allow starting in cold weather. Other engines may use a flame, or a heated tube, for ignition. While this was common for very early engines it is now rare. The first electric spark ignition was probably Alessandro Volta's History of the internal combustion engine#1600 to 1860, toy electric pistol from the 1780s. Siegfried Marcus patented his "Electrical igniting device for gas engines" on 7 October 1884. History Magneto systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...
