Running a gasoline engine using hydrogen-based power

President Bush has made a challenge to the American people to begin running our cars on hydrogen as soon as possible, and has allocated over one billion dollars for research to find out how to do that.

In a suburb of Toronto, Canada, a small company called Rothman Technologies, Inc., has in fact discovered not one but two viable methods for breaking down ordinary water into hydrogen and oxygen. Neither method involves the need to spend a billion dollars. They are simple answers. The existing engines in our automobiles could work with these systems with very little alteration and no need for an external support infrastructure like the one now provided by gas stations, and which would be required by fuel-cell technology.

To understand how these water-fuel systems work, it helps to begin by realizing that ordinary water is actually a “battery” containing vast amounts of energy. Water is H2O — two parts hydrogen combined with one part oxygen. And, as President Bush says, hydrogen is an excellent fuel. (more…)

How automotive engine grows ?

Automotive production down the ages has required a wide range of energy-conversion systems. These include electric, steam, solar, turbine, rotary, and different types of piston-type internal combustion engines. The reciprocating-piston internal -combustion system, operating on a four-stroke cycle, has been the most successful for automobiles, while diesel engines are widely used for trucks and buses.
The gasoline engine was originally selected for the automobile due to its flexibility over a wide range of speeds. Also, the power developed for a given weight engine was reasonable; it could be produced by economical mass-production methods; and it used a readily available, moderately priced fuel–gasoline. Reliability, compact size, and range of operation later became important factors. (more…)

Engine designed for fuel efficient

Fisher Technologies has developed a modern-day performance increase for all piston engines which dramatically improves the efficiency for conventional engines, both gasoline and diesel. This unique cutting edge technology provides substantial increases in fuel economy, significant reductions in exhaust emissions and more power just by adding a “yoke-arm” between the piston rod and power-shaft. A simple mechanical combination, never before developed for piston engines, uses a unique yoke-arm linkage that connects the piston rod to the crankshaft, yet leaves the remaining mechanical arrangement for conventional piston engines relatively unchanged.

Piston engines applies new technology

Finding important break-thru energy innovations to save fuel and money should be one of America’s top priorities. To date, the engine and auto industries have exhausted most avenues to improve the piston engine and little or no consideration has been given to the piston-rod mechanical linkage. Big-Step is a “leap frog” initiative by Fisher Technologies to move forward with a proven, patented linkage and modern-day break-thru for the piston-rod/crankshaft connection substantially improving the performance of conventional piston engines.

Both automobile manufacturers and engine designers historically have been mostly of the mind-set to design and develop “small-step” improvements, and such a mind-set has slowed the progress for discovering the much greater break-thru needed today. (more…)

E30 M3 engine from BMW

The E30 M3 is the BMW Motorsport-developed version of the E30 3 Series. Its S14 four-cylinder powerplant is a further development of the M10 unit and was chosen by BMW because of its compact dimensions. The S14 engine powered the E30 M3 from 1986 to 1991.

The E30 M3′s S14 engine was designed for racing applications and is therefore compact and high-revving. It combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments. (more…)

MINIs was developed jointly by BMW and Chrysler

The MINI Cooper delivers 85 kW/115 bhp (PS), while MINI One has 66 kW/90 bhp (PS). The Pentagon engine meets the EU4 emissions requirements and is one of the few engines on the market that requires no secondary air injection or exhaust re-circulation to achieve this.

The engine has an overhead camshaft with control chain and four valves per cylinder, with roller tip levers that control hydraulic valve balancing elements. The cast iron engine block ensures low levels of noise and vibration. The cylinder head is aluminum.

Active knock control means that the engine runs on lead-free fuel between 91 and 98 octane. The same engine tuning can therefore be used almost anywhere in the world, no matter what fuel grade is available locally. In addition, customers can choose freely if various fuel qualities are available in their market. (more…)
