An air-cooled V4 followed the next year, with pioneering V6 and V8 engines tried over the next few years before more conventional straight engine designs were settled upon.

Second hand Ro80s were virtually worthless in the 1970s due to the well-publicised engine problems, and a common " cure " for an ailing rotary engine was to simply swap it for a Ford V4 " Essex " engine ( as found in Mk1 Transits ) since it was one of the few engines compact enough to fit in the Ro80's engine bay.

The few exceptions have included the Yakovlev Yak-15, the Supermarine Attacker, and prototypes such as the Heinkel He 178, the first four prototypes ( V1 through V4 ) of the Messerschmitt Me 262, and the Nene powered version of the Vickers VC. 1 Viking.

It is interesting to note that Borland's Turbo Pascal V4 had a few quirks, the most notable of which was that it would occasionally ignore one or more lines of source code when said code was compiled.

The V4 engine has proven itself highly reliable, with few known faults.

Applications of control methodology have helped make possible space travel and communication satellites, safer and more efficient aircraft, cleaner auto engines, cleaner and more efficient chemical processes, to mention but a few.

Many early aircraft engines ( and a few in other applications ) had the crankshaft fixed to the airframe and instead the cylinders rotated, known as a rotary engine design.

Also known as slow-speed, or traditionally oil engines, the largest diesel engines are primarily used to power ships, although there are a few land-based power generation units as well.

The LH Torana was one of the few cars worldwide engineered to occupy four -, six-and eight-cylinder engines.

Since very few actual implementations of heat engines exactly match their underlying thermodynamic cycles, one could say that a thermodynamic cycle is an ideal case of a mechanical engine.

This technique is limited to the few engines and software tools that support it.

Heat-engine-powered generators are nearly universal, ranging from small engines producing only a few kilowatts to utility-scale generators with ratings up to 800 megawatts.

A few early gas engines had double-acting cylinders, but otherwise effectively all internal combustion engine pistons are single-acting.

Although rotary engines were mostly used in aircraft, a few cars and motorcycles were built with rotary engines.

Relatively few of the wiki engines currently in use were created after 2006.

General Motors did not succeed in having a Wankel engine meeting both the emission requirements and having good fuel economy, so in 1974 the company canceled its development, although GM claimed having solved the fuel economy problem and having obtained engines with a duration above 530, 000 miles ; unfortunately they just published a few papers on the results of their research.

Mistral claims to have overcome the challenges of fuel consumption inherent in the rotary, at least to the extent that the engines are demonstrating specific fuel consumption within a few points of reciprocating engines of similar displacement.

Although the rule still applies, the visible fuselage " waisting " can only be seen on a few aircraft, such as the B-1B Lancer, Learjet 60, and the Tupolev Tu-160 ' Blackjack ' — the same effect is now achieved by careful positioning of aircraft components, like the boosters and cargo bay on rockets ; the jet engines in front of ( and not directly below ) the wings of the Airbus A380 ; the jet engines behind ( and not purely at the side of ) the fuselage of a Cessna Citation X ; the shape and location of the canopy on the F-22 Raptor ; and the image of the Airbus A380 above showing obvious area rule shaping at the wing root, which is practically invisible from any other angle.

The basic design, with few minor changes, endured until Oldsmobile redesigned their V8 engines in the mid-1960s.

A few have a single engine and require one pilot to operate and others have two or more engines and require crews of two or more.

Although it was originally supposed to be available in GTOs and Firebirds, only a few SD 455 engines made it into Firebird Trans Ams that year.

A few Savery engines were tried in mines, an unsuccessful attempt being made to use one to clear water from a pool called Broad Waters in Wednesbury ( then in Staffordshire ) and nearby coal mines.

Forks has a display of one of a very few Shay engines remaining in Washington.

Most radial engines use overhead poppet valves driven by pushrods and lifters on a cam plate which is concentric with the crankshaft, with a few smaller radials, like the Kinner B-5 and Russian Shvetsov M-11, using individual camshafts within the crankcase for each cylinder.

A few engines utilize sleeve valves such as the 14-cylinder Bristol Hercules and the 18-cylinder Bristol Centaurus, which are quieter and smoother running but require much higher manufacturing tolerances.

A few days ago, she would have thought such an expedition as this utterly ridiculous ; ;

Black would have little trouble getting out, but it might delay him a few minutes.

`` We know Penny spent some -- and Carmer must have dropped a few dollars getting that load on ''.

Or else the North really believes that all Southerners except a few quaint old characters have come around to realizing the errors of their past, and are now at heart sharers of the American Dream, like everybody else.

A Yale historian, writing a few years ago in The Yale Review, said: `` We in New England have long since segregated our children ''.

`` You could come down to the office once a day, look over a few exchanges, dictate an editorial, and then have the remainder of your time for your more serious literary labors.

The wear and tear of life have taught me that very few friends of mutual friends long to see foreign strangers, but I planned on being the soul of tact, of giving them plenty of outs was there the tiniest implication that their cups were already running over without us.

Upon second thought we were forced to realize that we have very few reliable historical benchmarks against which we might compare the present situation, and that conclusions that present-day students are `` more '' or `` less '' religious could not be defended on the basis of our data.

And Lilly allowed me to help so that she could have her few little hours of escape.

The few scholars who have adopted the `` shore occupied by '' interpretation, Howorth, Shore, and Wade-Evans, have all been Celtic survivalists.

and among works of dystopian science fiction, not all provide intelligent criticism and very few have much merit as literature -- but then real quality has always been scarce in science fiction.

These new poems have only a few direct references to jazz and jazz musicians, but they show changes in Patchen's approach to his poetry, for he has tried to enter into and understand the emotional attitude of the jazz musician.

Long-range planning of programs and ways to finance them have become musts if the state in the next few years is to avoid crisis-to-crisis government.

The relatively few communities that have educational stations have found them of considerable value.

Granted that the Tammany name and the Tammany tiger often were regarded as badges of political shame, the sachems of the Hall also have a few good marks to their credit.

We have quite a few home-grown specimens of our own.

He seems to have at least a few 30- and 50-megaton bombs on hand, since we cannot assume that he has exploded his entire stock.

Cried one professor after a few months of Student Schiele's tantrums and rebellion: `` The devil himself must have defecated you into my classroom ''!!

Only a very few of the more advanced ones, such as India and Pakistan, have developed systematic techniques of programing.

If launched in a careful but determined way within the next few weeks, the Peace Corps could have several hundred persons in training this summer for placement next fall.

The last few years have witnessed what have been perhaps the most rapid advances in military technology in history.

Thus, in the last few years, a number of programs which looked very promising at the time their development was commenced have since been completely eliminated.
