49-PI is a 1. 27 hp ( 947 W ) 5 cc Wankel engine for model airplane use which has been in production essentially unchanged since 1970 ; even with a large muffler, the entire package weighs only 380 grams ( 13. 4 ounces ).

* Machinery parts that sound real, but if considering the actual machine, cannot exist: muffler bearings, diesel engine spark plugs, piston return spring, canooter valve, headlight or blinker fluid, or a top / bottom radiator hose for a Volkswagen Beetle ( which is air-cooled and therefore has no radiator ).

A shotgun or rifle having a barrel of less than eighteen inches in length or any other weapon, other than a pistol or revolver, from which a shot is discharged by an explosive if such weapon is capable of being concealed on the person, or a machinegun, and includes a muffler or silencer for any firearm whether or not such a firearm is included in the foregoing definition.

Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather than a power source.

Maxim is also noted as the inventor of the " Maxim Silencer ", a suppressor for firearms ( patented in 1908 ) as well as of a silencer ( or muffler ) for gasoline engines.

A scarf, also known as a muffler, warmstrangler or neck-wrap is a piece of fabric worn around the neck, or near the head or around the waist for warmth, cleanliness, fashion or for religious reasons.

A muffler ( or silencer in British English ) is a device for reducing the amount of noise emitted by the exhaust of an internal combustion engine.

Mufflers are installed within the exhaust system of most internal combustion engines, although the muffler is not designed to serve any primary exhaust function.

An unavoidable side effect of muffler use is an increase of back pressure which decreases engine efficiency.

This is because the engine exhaust must share the same complex exit pathway built inside the muffler as the sound pressure that the muffler is designed to mitigate.

Compression-release (" Jake ") braking, a form of engine braking used almost exclusively on diesel engines, produces extreme amounts of noise pollution if there is no muffler on the intake manifold of the engine.

The difference from the usual version is further stiffer continuous seam welded chassis and a Ralliart muffler.

Specifically, the entire undertray is completely flat and the muffler and rear valance were designed as integral aerodynamic components to decrease turbulence and rear lift.

Air is fed directly from beneath the hood through a visible slit passing into a dual stage variable intake manifold and then into ten individual throttle bodies before finally exiting from a dual stage titanium muffler.

A glasspack, sometimes called Cherrybomb ( a genericized trademark of a popular brand of glasspack ) is a type of automobile muffler in which the exhaust gas passes straight through the center of the muffler.

Replacing the factory muffler with one that creates less back pressure is a modification that is often made by hobbyists interested in increasing the engine power of their cars.

* the impedance of an acoustic component, like a wave conductor, a resonance chamber, a muffler or an organ pipe.

The exhaust pipes in automobile exhaust systems are designed as acoustic resonators that work with the muffler to reduce noise, by making sound waves " cancel each other out ".

Usage on public roadways may result a number of offenses, including but not limited to: no indicator lights, no rearview mirror, no horn or signaling device, no headlight, too-small muffler ( noise pollution ), improper lane change ( no blinkers ), or reckless driving.

The Hyper Pak consisted of a very-long-ram intake manifold meant to accept a Carter AFB 4-barrel carburetor, the AFB carburetor itself and an appropriate air cleaner, dual ( front-3 and rear-3 ) cast-iron exhaust headers, a large-diameter exhaust Y-pipe to connect to these dual cast-iron headers, a larger muffler, a 276 °- duration camshaft with appropriate valve springs and pushrods, a heavier-duty clutch, a manual choke control, a starter motor modification template and, in the full-race version of the package, high-compression pistons designed to increase the engine's compression ratio to 10. 5 from the stock 8. 5.

In a well designed tuned exhaust system, THE TOTAL INCREASE IN PRESSURE is in anycase MUCH LESSER than the one produced by a muffler.

Some vehicle owners remove or install an aftermarket muffler when Engine tuning in order to increase power output or reduce fuel consumption because of economic or environmental concerns, recreational pursuits such as motorsport and hypermiling and / or for personal aesthetic acoustical preferences.

* A muffler ( North America ) / silencer ( Europe ), to reduce noise.

She stood up, pulled the coat from her shoulders and started to slide it off, then let out a high-pitched scream and I let out a low-pitched, wobbling sound like a muffler blowing out.

Magnaflow performance exhaust was selected to develop a muffler that would allow maximum performance, and still deliver that killer sound, but be environmentally friendly.

Car seat and muffler hit by the Benld, Illinois | Benld meteorite in 1938, with the meteorite inset.

From spring 1932, the exhaust muffler was affixed by three clamps instead of two.

In addition, the cylindrical muffler was replaced by two flame-suppressing mufflers.

The muffler for internal combustion engines was developed in parallel with the firearm suppressor by Maxim in the early 20th century, using many of the same techniques to provide quieter-running engines ( in many European countries automobile mufflers are still called silencers ).

The sculpture of Paul Bunyan was manufactured by International Fiberglass, which mass-produced identical sculptures to sell to stores such as tire or muffler shops ( thus the sculptures are generally referred to as Muffler Men ).

He bought the land for $ 42, 000 to build a muffler shop and subsequently agreed to sell the land to a concrete company owned by the Docheff family to build a concrete batch plant.

New chassis details included a column gear shift, horns just behind the grille, battery under the right hand side of the hood, transverse muffler just behind the fuel tank, wheels by a different manufacturer, " Synchro-Flex " flywheel, hypoid rear axle and the deletion of the oil filter.

A Chimenea can also be repaired by the use of muffler glue to join major parts.

* Glasspack-an automotive muffler, often known by its genericized trademark name, Cherrybomb.

Other closings include the auto-parts manufacturing plant ( where Red Forman was a supervisor ), a local appliance and electronics store, Bargain Bob's ( owned and operated by Bob Pinciotti ), the local Foto Hut chain ( owned by Leo ) and the Forman & Son muffler and auto repair shop ( itself built in a former local muffler business ).

Both took factory produced motorcycles, removed parts deemed unnecessary and made them loud by removing muffler baffles for freer exhaust flow and perhaps to draw a little attention to themselves as well.

Additional options include " dark titanium " headlights, performance suspension and a performance rear exhaust muffler that increases the power output of up by to.

The fuel-injected engine also received a new muffler and the option of an upstream catalytic converter required on some models ( e. g. California ), necessitating a bulge in the rear apron sheet metal directly under the rear bumper, and replacing the distinctive dual " pea shooter " pipes with a single offset tailpipe – making fuel-injected models identifiable at a glance.

* BT-7 Model 1935: welded hull, redesigned hull front, new Mikulin M-17T engine ( licensed copy of a BMW engine ), enclosed muffler.

These covers combined with engine ISO mounts, extra shrouding, and a larger muffler made this series significantly quieter than previous series of Cub Cadets.

Engine power was increased 10 % over the base Zetec engine used in the ZX2 to 143 bhp ( 107 kW ; 145 PS ), courtesy of a recommended premium fuel re-calibration, new air inlet system, the performance PCM, improved Borla muffler and pipe ( M-5230-Z2 ).

It utilizes the stock engine that provides due to a revised engine mapping and a modified free-flowing exhaust that uses a baffle-free muffler.

Upgradable parts include the frame ( determines maneuverability ), engine ( acceleration and top speed ), brake ( deceleration ), muffler ( aids in acceleration ), oil ( aids in acceleration ), and tires ( improves traction ).

Engine power was increased 10 % over the base Zetec engine used in the ZX2 to, courtesy of a recommended premium fuel re-calibration, new air inlet system, the performance PCM, improved Borla muffler and pipe ( M-5230-Z2 ).
