For some engines it is necessary to provide counterweights for the reciprocating mass of each piston and connecting rod to improve engine balance.

For simplicity and durability, modern sousaphones almost definitively use three non-compensating piston valves in their construction, in direct contrast to their concert counterparts ' large variation in number, type, and orientation.

For example, an internal-combustion piston motor can have the fuel supply stopped, and then internal pumping losses of the engine create some braking.

For instance, in aircraft, turbine ( jet and turboprop ) engines are typically much smaller and lighter than equivalently powerful piston engine designs, both properties reducing the levels of drag on the plane and reducing the amount of power needed to move the aircraft.

For each rotation, an amount of water passes through the piston chamber.

For convenience, the designer may elect to use piston motions dictated by system dynamics, such as mechanical linkage mechanisms.

For example, an infinitesimal compression of a gas in a cylinder where there exists friction between the piston and the cylinder is a quasistatic, but not reversible process.

The torque developed by the action of the linear motion of the piston depends on the angle that the driving rod makes with the tangent of the radius on the driving wheel .< ref group =" note "> The relationship is simply: Torque = Force < sub > piston </ sub > x R ( the radial distance to the point of connection of the driving rod ) x cos ( A ), where A is the angle the driving rod makes with the tangent to the radius from wheel centre to driving rod attachment </ ref > For a more useful value an average value over the rotation of the wheel is used.

For example, for a thermodynamic system consisting of a piston containing water vapour, the particle number is the number of water molecules in the system.

For aircraft which utilised a jet engine strictly as a booster to piston power, see: Category: Aircraft with auxiliary jet engines

For the Turbo and Eurosport models the rear drum was replaced with a dual piston caliper and disc.

( For example, in the textbook case of a gas compressed by a piston, the gas is equilibrated at piston position A and compressed to piston position B ; in the Jarzynski equality, the final state of the gas does not need to be equilibrated at this new piston position ).

: For maintenance access to the radar instrumentation used for volume recording purposes and piston level readings.

For internal combustion piston engines with a fixed engine block of radially-mounted cylinders driving a rotating crankshaft, see radial engine.

For these reasons racing and piston aircraft engines are " dry sumped " using scavenge pumps and a swirl tank to separate oil from air which is also sucked up by the pumps.

For maintenance, a power assembly, consisting of a cylinder head, cylinder liner, piston, piston carrier and piston rod can be individually replaced.

For the B230 engines 1993, piston cooling, oil squirting jets were added to help alleviate piston slap problems on the turbo motors.

For example, it can be detected in the exhaust of internal combustion engines and tobacco smoke.

For Daytona 1967, two Mk II models ( chassis 1016 and 1047 ) were fitted with Mercury 7. 0 liter engines.

For the most part, car bodies were now manufactured at Elizabeth, South Australia, with engines as before, confined to the Fishermans Bend plant in Port Melbourne, Victoria.

For stationary and shaft engines including propeller engines, fuel consumption is measured by calculating the brake specific fuel consumption, which measures the mass flow rate of fuel consumption divided by the power produced.

For internal combustion engines in the form of jet engines, the power output varies drastically with airspeed and a less variable measure is used: thrust specific fuel consumption ( TSFC ), which is the number of pounds of propellant needed to generate impulses that measure a pound force-hour.

For the five 6. 4 meganewton sea-level thrust F-1 rocket engines of the Saturn V, burning together, the reaction generated roughly 1. 62 × 10 < sup > 11 </ sup > watts ( J / s ) ( 162 gigawatt ) or 217 million horsepower.

For example, engines used to be 1. 5 L units with either 8 or 16 valves, but these have now been upgraded to 1. 6 L units that meet stricter emissions rules.

For fixed-wing aircraft, one syllable names were used for propeller-powered craft ( turboprops included ), while two-syllable names indicated jet engines.

For example, Starfleet Academy cadets use impulse engines when flying from Earth to Saturn and back.

For example for internal combustion engines, single and two-cylinder designs are common in smaller vehicles such as motorcycles, while automobiles typically have between four and eight, and locomotives, and ships may have a dozen cylinders or more.

For example NASA's space shuttle fires its engines for around 8. 5 minutes, consuming 1, 000 tonnes of solid propellant ( containing 16 % aluminium ) and an additional 2, 000, 000 litres of liquid propellant ( 106, 261 kg of liquid hydrogen fuel ) to lift the 100, 000 kg vehicle ( including the 25, 000 kg payload ) to an altitude of 111 km and an orbital velocity of 30, 000 km / h.

For the 1963 season NASCAR engines were restricted to using a maximum displacement of 7. 0 Liters ( 427 cu. in.

For example, people may include spurious metadata into Web pages in an attempt to mislead Semantic Web engines that naively assume the metadata's veracity.

For this reason, Wankel engines are very well suited to snowmobiles, which often take users into remote places where a failure could result in frostbite or death, and aircraft, where abrupt failure is likely to lead to a crash or forced landing.

For this reason, solids have been used as initial stages in rockets ( the classic example being the Space Shuttle ), while reserving high specific impulse engines, especially less massive hydrogen fueled engines for higher stages.

For a chemical rocket the propellant mass therefore would include both fuel and oxidizer ; for air-breathing engines only the mass of the fuel is counted, not the mass of air passing through the engine.

For the 2000 season the team were forced to use 1998-spec Ford Zetec-R V10 engines, which were rebadged as Fondmetal engines in deference to his financial input.

For example large Jet engines operate around 10, 000 rpm, while micro turbines spin as fast as 500, 000 rpm.

For £ 15, 000 Bristol got the Cosmos design team, headed by Roy Fedden, along with a small number of completed engines and tooling.

For example, the Space Shuttle's main engines used turbopumps ( machines consisting of a pump driven by a turbine engine ) to feed the propellants ( liquid oxygen and liquid hydrogen ) into the engine's combustion chamber.

For operation in high temperatures, the engine's ventilation was improved by creating slits over the engine deck to the rear of the chassis, and cold weather performance was boosted by adding a device to heat the engine's coolant, as well as a starter fluid injector.

For better weight distribution, the engine is pointed ' backwards '; the output shaft is at the front, and the gearbox is in front of the engine, the driveshaft running back through the engine's sump to a differential at the rear.

For example, if the engine's fuel supply were to be reduced, this would cause the engine to run lean by whatever degree the fuel delivery was reduced, which can lead to engine knock or detonation.

For 1997, the 3. 9L engine's torque output was increased to 225 lb · ft ( 305 N · m ), with a compression ratio of 9. 1: 1.

For the 2008 Dodge Viper, the engine's output was increased to 600 hp ( 447 kW ) and 560 lb · ft ( 759 N · m ) via a slight displacement increase to 8. 4 L ( 510 cu in ) and the use of variable valve timing, among the first utilized in a pushrod engine.

For the 1991 model year, the 1. 5-liter 4G15 engine's new three-valve heads boosted power from, and a new GS sedan offered the 1. 6-liter 4G61 with and a standard four-speed automatic transmission.

For several weeks the engine's scheme contained a typographical error-" Millon " instead of " Million ".
